personally i haven't had bugs with paint room,

i think it just needs alot love put into it...

however power smooth does destroy the paint applied ... it smooths it to almost a point its erased

@CarlosanHey, I know you have responded to this before, but the baking displacement is still giving poor results. Hardened normals result when baking.

Steps:

1. From Startup menu choose Bust. Merge sub-tree so it is one voxel mesh. Turn on symmetry x axis. Autopo mesh. In retopo room unwrap uvs or auto uv. Bake menu choose "Bake w/per pixel painting w/ displacement". Set scan depth settings accordingly. Import Object for perpixel dialog, set to blender, add initial subdiv, keep UV, no smoothing. set texture sizes. Result in paint room is hard edges on normal map in texture editor and on model. These results are both with per pixel w/displacement and flat displacement from bake menu in retopo room. Expected result is a smooth mesh with displacement.

Hi!

Baking displacement for PPP is really tricky. It has sense mostly for the pipeline when use displacement for the parallax, but using the normalmap for rendering.

Both Images are from "Baking into Scene (microvertex) and Retopo->Microvertex (no baking). All with 1 or 2 subdivisions in dialog. Nothing with PPP. None of the baking options for microvetex are baking correctly from the retopo room.  Meshes should be smooth without these hard normals. This is happening in Windows as well. Forgive my frustration. Since when are these options used for an obscure operation like parallax. Even if it used for something like "Parallax" these results cant be good for that either. This is a workflow of 3DCoat is it not? Baking and painting displacement. It is very misleading to say you can bake displacement but now its used for a parallax workflow. I've used this workflow before without any problems. Can we at least get it working for the other baking options besides PPP? Seems to work as it should for "Industry Tuts" and the official youtube channel. Nowhere does anyone mention "Parallax". I do appreciate everyone on the team and your massive efforts, but from my point of view, it just seems like no one wants to address it. Baking should be one of the pillars of any 3d application. Thanks again for your time Carlosan. I know you are very involved with the community.

solved on version 2022.60,

• The texture baking dialog jumps back to the middle when you toggle an option.
• If you click ‘settings’ multiple times, it adds a dialog every time, on top of each other.
• On undo, the OLD circle was suddenly overlayed onto the new circle.
• Textures->Import UV does not flip the UV
• Fixed problem of stamp mode and symmetry in paint workspace.
• Fixed problem of curves and lines strokes w/symmetry in paint workspace.

I just discovered a new , first time i see it.

I was setting a smart material texture, one of my simplest setup: one texture in mask, modulate color, cylindrical projection, nothing more.

To get it applied correctly on my model, I had to scale down many times using the yellow square of the gizmo,

then suddenly, it became inefficient and started displaying only down and right arrows.
I tried to scale it up, but it's too late and doesn't react correctly.

As you can see on the screen, the top arrow has coming back while the left side is still missing.

I had to reset parameters to get it back to normal

 

I can easily recreate the problem by scaling down multiple times any other material:

Press with RMB over any gizmo icon to restore it to default size

Not a bug per se, but something that does need fixing.

Keystrokes, and pop-up hints for Glossiness, Roughness, and Metalness are mixed up and have been for a long time (since V4 at least - and still the same in 2023.01

1: Glossiness and Roughness sliders are interconnected (understandably), but the keystroke hint tells us that Roughness uses the "<" & ">" keys -

This is incorrect, "," & "." are the keystrokes used for both glossiness and Roughness . Yet in the keystrokes file they are < & > - and they do work.

2: Additionally, Metalness also shows the hints that "<" & ">" keys are used - when metalness has no keystroke assigned.

3: We are shown in the Windows/Sliders Menu that Glossiness Opacity uses keystrokes ";" & "'" but the ' key is used by the Quick Menu, and the ; key does nothing - there is no slider for the Glossiness Opacity on the brush or channel menu, so why is this shown in the Slider Menu along with these keystrokes? 

The Layers Menu has Gloss Opacity, but no keystrokes assigned. This is not what the Sliders menu is referring to.  The manual says the keys are ; and / (which also do not do anything).

4: The terms used are confused. The Channel controls on the Brush menu bar  menu uses Glossiness Intensity, but describes it as Metalness. Intensity and Degree also seem to be used interchangably.

"Export Objects & Textures" is out of order.

1,Select "Export Objects & Textures" in "Painting Room".

2,Uncheck "Export Textures".

3,Specify the save location of the object in "Output mesh" of "Export geometry". (This will close the "Export Textures" option.)

4.Click "Export" to export.

5,Select "Export Objects & Textures" again to bring up the panel, the "Export Textures" option is closed. Checking the checkbox does not open any options.

The option cannot be set even if it is checked, but it can be exported. However, existing files will be overwritten. When you open "Export Objects & Textures" again you will see the options.

The same thing happens with "Export geometry".

 

I have a video on my Twitter.

The sliders in paint room layer system are very slow when I work with 2k or 4k maps. I have i7 6700k and GTX 1070. When I move the slider it performs operations and my fps change to 10 or 11 fps. I think that the event of sliders are bad configured. It needs to perform the operation after the user release their LMB or optimize the performance to get realtime feedback.

Other bug or I think that is bug.. In the export textures dialog. I wanted to export my textures in EXR 16bits, but in the options when I choose EXR, I only can see 8bits. 

I reported in other post about the layer masks.

@lunarbor 3DCoat-2023-12 - The export dialog has been corrected; there was a problem where the UI would not refresh depending on the Export Geometry/Textures checkboxes.

Hello,

I recently tested 3DCoat Textura Demo (Win10, Huion 950) and I would like to ask about these (not sure if they are all bugs or if I overlooked something) :

1. "Rotate around..." camera navigation - by default it is set to "Last Draw Point", but when I changed it to something else, there is no way to activate it again.

2. "Color Swatches" window - not working properly when undocked and going from "Small" to "Huge" preview is doing nothing. Also - is it possible to rearrange contents of this table?

3. (not bug I presume) - When changing tools, Stroke Mode is stored, but not when the last one - selecting whole faces/polygons - is set. Would be very handy for freezing parts of lowpoly models.

Are these bugs/behaviours present in previous versions? I really like the workflow of this software.

[Carlosan]

Hello and welcome !

Are you testing latest version 2023.12 ?
