Wow, it's been nearly a year. Decided to revisit 3Dcoat on Linux. Using Fedora 43 now and still the same error. I ended up manually changing the name of existing folders in /home/user/Documents/3DCoat/UserPrefs/SmartMaterials/ to start with capitals i.e fabric -> Fabric. Now I'm able to install new smart materials via "Install Extensions" without errors. No idea if there will be any consequences for this change. However, I've discovered that mouse wheel scroll doesn't work. Always something  In case this helps people using other distros, I've had good results running Ubuntu 24.04 inside Distrobox. Just have to install some missing libraries within the Distrobox container.   #install fuse sudo apt install fuse #install missing libraries sudo apt update && sudo apt install -y libgtk2.0-0 libcanberra-gtk-module libpackagekit-glib2-18 libnss3 libcanberra-gtk3-module packagekit-gtk3-module Then have to download fbx-sdk and install it inside the container as well. Everything seems to work, including the app-link with Blender 5.0. Well, everything except the mouse scroll wheel. Tested on the Linux 2024 and 2026 builds. No download links available for 2025.

Hi,  quick question - is anyone in here using current lineup of XP Pen tablets with 3D-Coat and could share their experience? Currently, I'm using Huion Kamvas 16 gen 3 and it's perfectly fine, but I'm thinking about jumping to 19 inch screen in 4k res, so I'm considering XP Pen Artist Pro 19 gen 2. Normally, I would go with Huion Kamvas Pro 19, but the price difference is a bit high because of the touch feature on Huion, which I don't care about and won't use that feature.   So, any info about XP Pen performance with 3D-Coat and other 3d apps? Does the pen pressure, tilt and all the buttons work correctly in 3D-Coat, etc.? 

Contact support@3dcoat.com asking for support.

Are there any other linux builds posted somewhere other than the latest 2026? My license is available until mid 2025, but the only download options I see are for February 2024 or your link for 2026.01. Is there anything else in between?

Okay, I'll have to wait for the 2026 version then. In the meantime, I guess I'll just have to erase and smooth the airbrushes then.

Yes, it is a current limitation of the paintengine The dev team is working on the 2026 release that migrate the engine to GPU accelerated for ppp

Yes, this request was posted on our Mantis bug tracker web

To replicate it, just use the airbrush and make it really large and spray the entire sphere at the main viewport screenspace for a few seconds. The brush should be bigger than the mesh so it can wrap around without you moving the camera, like you are trying to airbrush both sides of the sphere so it is 1 consistent paint coating. In substance, Tri-planar projection will allow you to wrap airbrush from front, side and back side so that you have an even spray so theres no gaps or seams. Just wondering if there is something like that in 3d coat too, because I can't find it and it seems really useful.  How do you airbrush or paint a round object all the way around and have it smooth, consistent and seamless then without extra brush strokes? 

Just wondering then, so there's no way to just paint on the UV texture around / outside of the seams, is there? I feel like that would solve a lot of issues since this should be a really easy fix normally. Can you ask them to let that be a possibility, or is that just how the software works?

Sorry if this is something simple but struggling to find documentation. Followed this link's instructions but for some reason, any areas without UV's are gray. Curious if there's a proper way to make Layer 0 fully black upon export. https://3dcoat.com/documentation/manual/workspaces-rooms/paint/opacity-transparency/

Export as png model, not jpg teethBder.fbx

Sorry, I can't replicate this issue on 2026.1

I just opened the file you sent and it was still jaggy looking and bleeding involved. I even exported it out of 3d coat to blender to see if it actually changed, but the results were still poor. I didn't do anything else besides open the file. See below for screenshots inside 3dCoat and exported to Blender to view. 3D coat textura 2025.17 so the latest publically available one.

sorry, i am attaching the projects   cloth.3b teeth.3b

Can you zoom in on the texture editior, I can't see it clearly because its really small and I tried magnifying it but its still too small. Thats what I originally did, if you look at the original picture I have the islands separated by the gum and the teeth and when I used fill it created the jagged lines. How did you fill the color on the Texture Map editor so that it fully enclosed the islands without jagged edges or bleeding, because I have been trying all day with 10 different isolated islands and meshes and it doesn't work like the one you pictured. It leaves bleeding and jagged eges at it. Did you not use the fill tool on the UV texture? Can you explain exactly how you painted it so there was no edge bleeding. I need to know how to do this, its very important but its not working like intended.   Look at the clothing item FBX above, I am trying to do the same thing with that but its not working. Separated islands, with different colors for clean edges but it just bleeds. Can you show me how to do that with the clothing item above, this is affecting all my isolated islands.

The only way I found to keep same result was to separate the UV islands at seams edges. Look at the UV island on Texture Editor Panel, are more small the the original.   Anyway we need better padding option, similar to "UV Space Neighbor" on Substance Painter.  Feature request added. Thanks for point it up.  

Its not the mesh thats the problem, I just need to know how to wrap the airbrush around a model, it doesn't have to be this leg, it could be a normal sphere I just want to wrap brushes around an object like in Substance Painter with tri-planar brushing. This isn't a technical problem with the mesh, I am just asking how to airbrush around an object without a harsh line because theres no tutorial on it and the only solution I have found is erasing and repainting. Here is an example of what I mean, with the default 3d coat sphere with just the default airbrush in screen space..
