Updated to 4.5

  • Do NOT use beta builds in production if build is not marked as [sTABLE].
  • Keep backups of scenes, presets and materials. Better - do backup of folder MyDocs/3D-CoatV4

For example, rename it MyDocs/3D-CoatV4 to MyDocs/3D-CoatV4_OLD, run beta, work there. If you want to get back to 4.1.17D -  

rename or copy MyDocs/3D-CoatV4_OLD to MyDocs/3D-CoatV4

- Bake->Update paint mesh with retopo mesh

- Fixed "Edit projetion in ext editor" issue in vertically aligned window.

- "Ignore back faces" works for Move tool in surface mode.

- nice bewel in primitives with "sector" option

15.05.2016 4.5.39

- BIG ONE: Baking multiple useful maps in Paint room->Textures->Light baking tool

- IMPORTANT (main reason of this build): fixed white spot issue

- Sculpt room : Geometry : Retopo mesh->Sculpt mesh

- Retopo: Update Paint Mesh with Retopo Mesh, it replaces geometry in paint room with retopo mesh

- updated installer. It registers Coat as usual program, it is now possible to uninstall each build from "Programs and components", each build has own place in start menu.

- Raul's tools included - QuadPaint etc. Pay attention that it are essentially BETA tools.

14.05.2016 4.5.38

- There is possibility to bake Sculpt objects onto current paint mesh. Retopo->Update paint mesh. It will keep painted textures and update normalmap and layers related to Sculpt volumes. It simplifies workflow when you need to change something in geometry on very late stage. Also you may bring paint mesh to sculpt room directly using Geometry->Paint mesh->Sculpt mesh.

- "Ignore back faces" works for Move tool in surface mode.

- If you select some voume via H key VoxTree will be scrolled to show selected volume.

- Material navigation in UV mapping mode tweaked (Speed of transformation).

- Fixed longstanding palette "Load" .aco files crash.

- fixed problem of moving collapsed maeria preview window

- AO correctly used for PBR materials for surface /voxels. There was problems since shaders unification.

- Transform/copy tool -> Import accepts not only psd files but regular images as well. It simplifies applying images over the model.

17.04.2016 4.5.35 [beta]

- Export constructor done! It is very important feature to pack many channels into one texture in customable way. It will help to adopt 3D-Coat's texture export for any render or game engine. Look v-ray preset as example. There will be more presets for convenience.


- Smoother/angulator/sublivide got 3d lasso in e-panel

- Fixed proble related to saving/import vox tree chunks to 3B file

9.04.2016 4.5.34 [beta]

- Cut and Connect for lowpoly modeling in retopo room.


- New import option for PPP - import eah material as separate UV set.

- Fixed problem of "Apply symmetry" and mesh corruption.

- Relative paths to textures in exported OBJ files.

- Fixed problem of OBJ export, vertices are correctly distributed between objects, not concentrated in first one. This proble was the reason of C4D crashes durig import of Coat's obj files.

16.03.2016 4.5.31 [beta]

- BIG library of primitives released, includes spirals, screws, etc.

- Corrected diffuse component rendering. It result with more contrast and pretty lighting. Now PBR looks really better and is well compatible with other engines.

- Rendering quality in render room improved. Now all samples are summarized with gamma correctio that leads to much better visual result.

- "Conform retopo" improved - Undo works correctly and reropo mesh visible during transformations.

- Crash in render room fixed.

- LMB/RMB/MMB outside of Sculpt RMB menu will close the menu instead of sculpting action.

- RMB over object during navigation will not trigger RMB menu.

1.03.2016 4.5.29 [beta]

- Shading using PBR was essentially changed. Now GGX lighting natively supported. What does it actually means -

1) Almost all voxel sculpting shaders are PBR compatible now. Each shader has rich set of parameters, including different textures, sss, gloss, metalness, cavity and bulge settings. Very good support of cavity and bulge is present in realime.

2) All PBR shaders effects (except pseudo SSS effect) are exactly baked into paint room.

3) PicMat-s are also present but it is not guaraneed that they will be baked correctly, so use them only on intermediate stage.

4) GGX exact support means compatibility with most of current engines and renders.

5) Painting over mesh is "as is" without modulation on background shader color. But painting over layer 0 is disabled for voxels/surface.

- Factures included in this build (DX only). It is essentially beta stuff, so it is just for review. Factures are addional covering over the voxel/surface objects. We take tiled texture and mix it with random pieces seamlessly. It allows to cover meshes with tiled textures without tiling. Also it allows to texture objects without UV-s at all. It is very important for landscapes. It was developed long time ago, but now we decided to expose it as beta tool. To use factures go to Paint room, open Windows->Popups->Factures and select facture. Now paint over object. Textue will be modulated by selecteed color.


- Old shaders are disabled because shaders system was completely re-made.

- Old panoramas are disabled, you will need to add them as HDR or EXR files from scratch.

15.01.2016 4.5.26 [beta]

- Big and important! Anti-atiased painting introduced everywhere - vertex paintg, ppp, mv, ptex. It is applied to stencils, materials, brushes, text, curved pictures.

See examples (stencils) - https://t.co/zI9lOpLUBt , text - https://t.co/iLTQsmmaik

- Export of metallness is possible in gloss/specular color workflow as well.

- Export dialog got controls to correct exported textures via gamma and curves correction (preparing to make good presets for all renders).

- Move via brush tool in retopo room will not snap vertex to cursor position even if thre is only one vertex in brush.

- Contours for cutting may be saved in UV and Retopo rooms, look in Commands->Save contour. Files may be saved as EPS or DXF. It is very useful for real thing production - like shoes or acryl details.

4.5.25 [beta]

- problem of loosing PBR materials probably fixed, but anyway requires careful checking.

- Edge loops with SHIFT + click in retopo/select/edges mode

- 3D spline points from E-panel may be transformed by gizmo and re-snapped to surface using "Attach to surface" without flattening.

- Resolved little scripting issue - 3d-coat.com/mantis/view.php?id=2056

- Cancel in Smart materials editor will remove only completely empty materials (they appear if you press + button). Previously condition for removing was less strict.

- If you you are in 3D selection E-mode, loading spline will not switch you to 2D spline mode. Transforming 3D spline with gizmo is also allowed.

- If you bake multiple times same scene again and again, 3D-Coat asks if results of previous baking shouls be deleted.

- In lock panorama mode screen refreshed when you rotate panorama. But panoramas management is still under construction....

- layers folder support metalness/gloss

16.01.2015 4.5 BETA6

- correct texture UV editor view

- robot/preview sphere included in distributive

- Objectify was super slow. I fixed it in beta6. Extra functionality in objectify - removing small flying noise, unifying small pieces, decomposing to child volumes, sorting by size.

- 3D-Coat now may import object space normal maps (with auto conversion to tangent space). It guarantees normalmaps compatibility.

- "Draw on plane" extended on Curves/Text/Snake clay

- Fixed seams problem in ppp - colored pixels near the seam in some cases.

- View seams in paint room - bit.ly/1shKfFR

8.01.2015 4.5 BETA5

- Fixed crash in pose tool

- Fixed crash in fill tool

- GL version works!

- snake fixed

- fixed problem with sliders numerical input in Layer blending palette

- panoramas updated

- different small stuff like default hotkeys

6.01.2015 4.5 BETA4

- Important!! fixed critical problem related to broken export.

- Compatibility/GGX/Blinn-phong shading. Compatibility shading preserves colors as well as previous coat's shading but is able to use advantages of PBR.

- PBR preview in paintbrush mode

- new materials


3.01.2015 4.5 BETA3


- fixed problems related to rename/move/duplicate items in folders. Need te be carefully checked anyway.

- HDR support for panoramas. Panoramas will be auto - leveled. I included several really good panoramas i Panoramas/ folder, set other default panorama.

- Materials in 4.5 will not destroy 4.1 materials and vice versa. New mats has extension .pbrm instead of .xml. But if you want to use older materials - use Edit->Convert materials

- Top row conditions are now same as in materials. Realtime preview should work correctly for both - paint conditions and materials.

- View separate channels - color/specular color/gloss/metalness

- a lot of paint problems solved.

- UDIM naming for UV-sets supported with tiled import. Fixed seams problem related to tiled import.


24.12.2014 4.5.BETA2

- Option "Lock transparency" in "Layers blending" option works correctly for metalness and all tools.

- RMB over material allows to re-fill with the material all non-transparent area. It allows to change easily the material used for layer.

- bugs related to material folders fixed.

20.12.2014 4.5.BETA1

- PBR & Smart PBR materials introduced.

- a lot of bugfixes.

4.5.b1 CUDA took forever to load...got that white-wash "not responding" screen, so I waited a while for it to finish.  I did load, but it also may have taken a bit because of my firewall.  It loaded my presets, just fine.  It's weird going back to 3DC after using ZBrush so much lately.  I keep trying to increase brush strength using S.


I also like the preset buttons.  I wonder how well that will work when you have tons of them, though.  I take it the new procedural material system didn't make it in...never mind, I found it beside Stencils.  I just don't know how to apply it.  Pulling up one of my own "materials" ends up showing just a blank sheet.


EDIT:  OK, so I was able to see the material by changing from the default Cube Mapping to Camera, but I have to do that every time I pull one up and painting over it in the Voxel Room onto the sculpture doesn't appear to have any effect.  I also noticed that if I load the DX .exe, it shows I'm using 4.5.b1(CUDA), but if I load the GL one, it shows I'm using 4.1.17D(CUDA).


This yellow adjuster also appeared out of thin air as I was right clicking to adjust my brush size:




I can't recall what it does and I certainly don't want it in my way.


It would also be nice to be able to get the environment back on a reset, rather than having chosen an un-preferred environment image and not knowing how to get back to default.

Curious as to know when a Linux PBR 4.5 beta will be released. Are you going to work through problems discovered in the windows version first before releasing a Linux beta?

Awesome!  :D  I too am looking forward to the Linux version, any ETA?

A number of things:


1) Too many materials? I requested a way to tag and search materials, ala dDo and Substance. I think it's really necessary especially since  you can have so many of them. I think then we could just have one folder, and not worry so much about organizing them, as long as they are tagged. So if you want this too, we should start a Trello for it, or maybe Andrew will just do it. ;)


2) The material gizmo shouldn't be showing up like that all the time, it was happening to me too. It's a bug. Mantis time.


3) Watch my latest video, it show you how to put a material together.


4) Only use the DX version for now. Andrew noted above that GL was not updated, but still included.


5) To change the environment, you can do so under the Camera button (top right of the viewport). At the moment the options are limited, I'm hoping for some more that I requested with Andrew.

Pbr preview looks nice, but I can't do "normal view".

I can't assign multiple preset to different part of my model.


This is probably because I don't understand how it works but for a first time this is pretty discouraging.



Hey dude.


When you say normal view, do you mean the normals?


Assigning multiple presets to different parts of your model must be done manually, so it's slower than dDo in this regard. The upside is that you can control exactly where they are placed by brushing, or using Stroke modes, the closed curves and lasso modes work pretty well here. I think the idea behind them hasn't really changed from what they were before they became "PBR" materials, they are still really stamps of a sort.


To place them quickly I've found that I paint a Color ID map, then just use the fill tool to fill those areas with the PBR Mats I want. Upside to that is you can then, if you need to, use the Color ID map you created in another tool or engine.

When I say I can't do "normal view" I mean, if I don't go into fill mode to bring the pbr preview gizmo I get no pbr shading.


As for assigning multiple materials to a model I don't get it. At all. Would love a quick explanation in that regard, cause right now all I get is a single mat applied to the entire model and it's changed as soon as I click another mat (not sticking to parts).

Ok cool. Yeah, that makes sense.


For PBR shading to work, which IMHO I'm not sure is entirely 100% PBR accurate (only Andrew could say I'm guessing), you need to turn on an environment map from the Camera button. There should be one selected by default. If there isn't one, let me know and I'll post one up for you to try.


I'll see what I can do about recording a quick demo video for applying the mats. I'll type up a longer response here in a few as well.

Ok, to apply mats, just use the regular painting tools, like the paint brush, airbrush, pencil and fill tool. If you're familiar with dDo, ignore what you know there, those things don't apply here. PBR Materials in 3DC are no different than they were before, when applying them. The fill tool will fill the entire area, the brush tool (and other alpha respecting tools, airbrush, pencil, etc.) allow you to paint them on directly.





  • Activate a PBR Material
  • Choose a tool to apply it with (brush, pencil, airbrush, etc.)
  • Make sure depth, color, gloss and metal are on where applicable (and values higher than 100%)
  • and stroke them on


When using the fill tool, it will fill entire areas of the mesh as before, whether it's using surface materials, disconnected mesh islands, objects or a layer. That's only good if all you want to do is fill huge swaths. Now, where it comes in handy is when you paint an area with a single solid color. Then use the fill tool. I'm in the process of working up a video with this in mind.

Cool! Glad you got it working for you. :) I sent Andrew a few, but I'm not sure if they are part of the distro or not. Let me know, and I can upload them for you to dissect or use the image maps to make others.

I did some cool looking painting!....but I just cannot get it to export the obj with textures without a crash? Anyone exported?


Edit ..I managed to get something exportd be deleting an obj and unhiding something else ....but dont really know what is happening.

         I am trying to render in Carrara but have no clue how to make it look like the Coat image.....( massive sad face)

I meant the file format (.hdr), not HDR as in High Dynamic Range. Probably I shouldn't use the caps.

For now if I want to load it into 3D-Coat, I need to manually convert it to .exr first.

Most of HDR environment maps on the Internet usually come as .hdr files, and majority of software supports this format. Hence my question.

It's not a big deal, just something that would be nice to have.

Is there a way to switch off the PBR , I have set the background back to vertical gradient and I can still see the effect and the reflecton from the panoramic image. Is this how it is supposed to work? I thought the lighting would go back to how it was if you reverted back to the gradient background.

Hey there folks,


Glad to see 3DCoat adapting PBR. While playing around with it today I noticed a few issues. I am using the same EXR in Unity 5 (Beta 17) and also in Substance Painter and now in 3DCoat to make sure I am using the same lighting conditions to compare. While it all looks good in Unity and Substance Painter, it doesn't in 3DCoat. The lighting has an odd green touch to it and seems generally darker. Normal maps also seem very flat currently (see image). No matter what settings I have in the shader (normal map cranked up) it always looks rather flat and uninspiring compared to Substance Painter/Designer/Unity. 


What are the plans currently on exposing more light/rendering features in viewport? Is what I am looking at in the viewport rendered in Linear color space? Also, are there any plans for further post effects like Tone Mapping, etc? 


I am aware that this is a first public beta. With that said I also hope that there will be performance improvements as some PBR materials act very laggy when trying to paint and I have pretty beefy hardware.
