I found a workaround solution to the missing smart materials (if you have the windows installation of 3dc) Copy the folder "patterns" from 3D-CoatV49 (in windows) to 3D-CoatV49 (in Linux). For some reason the "patterns" file in the 4.9.66 linux download is 0 bytes when extracted.

Thanks for confirming it isn't something peculiar to my setup.

I've got 4.9.66 working and registered following these instructions on Ubuntu 20.04 (thanks for the post). However I do not have any smart materials. When I got to edit>Relocate 3D Coats data it is pointing to the correct directory which is ~/Documents/3D-CoatV49 Anybody know how to get them work ?

Thanks very much Sergyi, very useful information and helps clear up what all the folders are for and where I could install 3D Coat on a linux system. I've decided to stick with installation in the Home folder, its a little cleaner than installing to the Desktop. Messing with environment variables, FServer etc is starting to get a little complicated for a relatively new user to Linux.

Hi Carlosan, I copied the tar.gz file to the Desktop and extracted it there. It created a folder on my desktop 3DCoat-4.8.20 I then followed the guide in the previous post to create the 3D-Coat.Desktop & 3D-Coat.sh files and installed them in the directories suggested in the guide. When I ran the program it still created these folders in the Home directory ( 3D-CoatV3, 3D-CoatV4, 3D-CoatV4.8, Applinks ). So installing to the desktop is a little bit more messy than installing to the Home directory as I now have a folder on my desktop in addition to 4 extra folders in Home . 3D coat is running fine but I've emailed Sergii to see if he can provide any information as to where it should be installed. I think that information should be added to the guide.

Hi the guide how to create a shortcut is very useful to get 3DC up and running in Ubuntu based linux distros. Is there a guide where to install 3dc on linux. I mean which directories it should be installed to. When I unpack to Home or /opt I end up with 3 folders in my home directory 3D-CoatV3, 3D-CoatV4 & 3D-CoatV4.8. It seems kind of messy and clutters the home folder area or is that normal and how it is designed to be ?

Layers -> Import ( color, roughness, metalness, depth). On import it will allow you to select which uv map to import to.

I just found a solution. Use the layers menu export your All layers Color to psd, Metalness and Roughness to TGA Imported your updated model via File > Import Object. Then use the layers menu to import the color, metalness and roughness to the new uv set. The you can delete you previous model from the paint object dialog.

Thanks Carlos for the suggestion Unfortunately it didn't work in this case. The error I get is: "The imported object does not match the object in the viewport. The imported object with the new UV-set must have the same vertices and faces order" I don't really know what that means to solve it. I tried with both obj and fbx formats and get the same error.

Hi I've created several layers and painted my model with smart materials. I've then decided to re-uvmap part of the model in Blender and re-export to fbx. Is it possible to replace the model that is in 3d Coat with the updated exported model from blender and apply all the layers to it ? The uvmap name on the updated model is the same as the one in 3D coat

When I import a obj model with its uv maps into 4.8.07 I get a low res pixelated grayscale image of the uv map in the background of the Texture Editor. Is there a way to turn off that pixelated image so it is just a nice plane dark grey background ? I find the pixelated image distracting while painting in the Texture Editor.

I mainly do aircraft and need to draw straight panel lines on curved surfaces. Curve stroke with 2 points works but creates a curved line on curved surface when viewed in a ortho view. PS This isn't SOS urgent but I keep hoping with each update throughout the 4.0 release it will be fixed.

The glossiness map is grayscale map like a spec map. Some render engines support glossiness maps and some don't. If your render engine doesn't support it you might be able to tweak it in PS or your 3D application so it gives acceptable results to you. By tweak I mean play with it brightness contrast, opacity, those sort of settings. Perhaps this thread will help

I'm using the CUDA x64 version on W7. Hopefully someone else can suggest something to help you. Have you tried other models ? Do they have same problem ?

Layer 0 is default gray colour uv applied model on import and layer 1 is ready for painting which you would normally rename to something more appropriate. I don't get a layer named after my imported model but could be something different in the way your 3d application export to obj. It works fine for me. After filling the whole layer did you hit the close button in the smart materials palette to deselect the smart material ? Otherwise when you paint it is just painting the same smart material that was used to fill the whole layer. Also make sure the little green ball in the top centre of your screen doesn't have a cross through it. That is the color channel. If it has the cross then click on it to activate. Sorry if I am describing obvious things but you did say newbie in your question.

Yep, it still works without smart materials. But there is no spec map export option, only glossiness.

Javis, thanks very much, it now looks in modo just like I see in 3DC ! I would never have figured this out on my own. Just for other users - there is more to getting it to look the same in Modo as it does in 3DC than just the material setup. It is also the environment image, light setup and material color spaces of each of the maps generated by 3DC.

Right click on material and set the preferred mapping to cube mapping. Does that fix the icon ? If you change to cube mapping in preview options, that won't work.

Try Right click on material & "Restore factory defaults". To get the normal icon you will have to change its mapping to cube mapping as carlo says.

Hi Carlo I eventually found a solution to this, (although it would be a lot easier and quicker if the line tool worked on curved surfaces). Setup the 2D grid and 2d snapping. Use the Curve stroke tool and place numerous points along the length of the line, place more points on the curvier parts of the mesh which will stop the line projecting onto the surface in a distorted way (as per my first post in this thread).

Thanks Javis Message sent with zipped 3b file. BTW I did solve my dark texture issue. I've never used normal maps in modo before (always bump) but found out on the modo forums you have to set the colorspace of them from default to linear which solved the dark texture issue. I don't know how to solve the metal effect on the edges though.

Thanks for this Javis, it really makes the workflow easy for 3DC Modo users. I am having some problems in Modo 801. I can't get the metal effect to show on the edges ? I'm also getting some darkening of textures and they look glossy on the rear of the engine for some strange reason. I exported color, roughness, metalness and tangent maps from 3DC and put them in the v3.4 shader in the correct spot but don't really know what is wrong.

Its pretty hard to draw with just a brush using grid snap as the brush just wobbles off the grid as you drag it along. It is easier with a big brush but I'm trying to create fine detail and need a small brush. Its pretty disappointing that 3DC doesn't have the ability to draw straight lines. except at 45° increments. Having said that, thanks for all your help Carlo !

I'm not sure what it is but when using the line tool over any curved object it will not draw except for the start and end point. I have tried this on 3DC default sphere object. I have also tried it on imported cylindrical meshes (obj) from my 3d application. If I use the 2D or 3D grid with snapping on, it has no effect on the line tools ability to draw over curvature and I still just get a dot at each end of the line. There is perhaps a checkbox somewhere in 3DC which you have checked which solves this issue, but if there is I cannot find it.

2D grid is fantastic and very versatile. Thanks for making me aware of it. I don't understand why you can draw on a curved surface and I can't. I just get a dot at each end of the vertex line tool and it draws through the mesh. Are you using the vertex line tool or have you used a brush ?
