Thank you very much for your explanation — my issue has been perfectly resolved. After switching to the OpenGL normal map preset in 3DCoat, the normal direction problems no longer appeared in KeyShot. Although the normal map itself still seems to show errors along the UV seams when viewed directly, the actual KeyShot render looks completely correct, with no visible issues at all. This preset change is honestly amazing. That said, I feel that the KeyShot export preset in 3DCoat doesn’t produce very strong results visually, at least in my case. I’m not sure whether this is due to some incorrect settings on my side in KeyShot, but the PBR material response feels rather subtle or muted, and I’m not sure if I’m describing this clearly enough. From my experience, exporting from 3DCoat using the Blender preset and then using KeyShot’s standard material type actually gives better results. Simply setting the contrast of all grayscale (black-and-white) textures to 0 in KeyShot already helps improve the final render quite a bit — at least perceptually, that has been the case for me.

The only difference between OpenGL and DirectX is that the green channel is flipped. KeyShot primarily uses OpenGL for its user interface, real-time viewport, and core functionality.  For OpenGL, you may need to invert the Green channel (Y+) depending on the target engine, although 3DCoat usually handles this in its export dialog. - 3DCoat Normal Map Format: When exporting textures, ensure the Normal Map is set to OpenGL.     version 2026 have added Keyshot, but you can create your own. Test another preset to find which one works for your current workflow

Thank you very much for your suggestion. However, I couldn’t find an Unreal Engine 4 preset on my side. I used the export settings shown in the image I sent earlier, but the manually painted normal map still shows the same seam issues. Would it be possible for you to share a screenshot of your export settings? That would really help me understand exactly how the setup should be configured.

Is anyone else having problems with their Brush disappearing when you switch (using Vertex Paint on a Sculpt Object) to the Paint room? I have had this issue on and off for over a year now...and I wanted to know if it is some kind of corrupted .xml file in my Documents/3DCoat directory, or not. I think this is DEFINITELY a BIG Bug because it's repeatable, even if I temporarily rename my Documents/3DCoat folder (so 3DCoat will generate a fresh new directory on the next opening of the application), I run into this problem over and over.  To repeat this issue, I simply pick a brush alpha and instantly lose my brush in the viewport.

Hi  At export, try selecting another preset as Unreal 4 Hope this help

Hello, I created a tight-fitting suit in 3DCoat, going through the full workflow from sculpting and retopology to painting in the Painting Room, and then exported the model as an OBJ. After importing the model and textures into KeyShot, I noticed some issues. The model itself and most of the textures look fine, but when I checked the normal map, I found that normal errors appear along some UV seams. No matter how carefully I check, I can’t find any problems with the normals inside 3DCoat. So I opened the exported normal map in Adobe Photoshop for inspection and discovered that, along the UV seams, some normals in the texture are actually inverted. What’s interesting is that the incorrect normals only occur in the areas where I manually painted the normal map. The normals generated through baking appear completely correct. Could this issue be caused by something I did incorrectly during the normal painting process? And what would be the recommended way to fix or avoid this problem?

Hello everyone. I just came back from doing photogrammetry in Petra and Wadi Rum and I'm starting a tutorial series about my workflow. 3D Coat is in the centre of the whole production and an absolute necessity. If you are interested then check out my YouTube channel and feel free to comment with tips and tricks if you see anything that could be done better, I always want to learn more. The video below is an overview of what I'm planning to do. I hope you like it.  

Yea, maybe that's it. I THINK I had my brain screwed on backwards that day. I had Opacity, iirc, set to 100 % LOL 

I run into things like this every so often, but it is usually because I forgot to do something on my "Pre-Flight Checklist" of sorts. It may be that I was trying to paint on a layer that is hidden or locked, or that one or more of the channels (color, depth, glossiness) wasn't enabled. In this case, I think it is because your OPACITY is set way too low for you to notice when some paint has been applied. At 13% Opacity, you are probably not going to see much, if any paint, laid down...because it would be very faint.

You already have PolyGroup functionality in the Sculpt Workspace, via the Pose (Advanced Transform) tool using selections you make with it. You have different modes of selection and when you have created a Pose/PolyGroup selection, you can store it to a Paint Layer. If you have a FREEZE selection made to an object and switch to the Pose tool, 3DCoat will read that Freeze Mask as a Pose selection. It works in reverse, too. If you have a Pose selection made (in Surface mode only) and suddenly step out of the tool, you will see the Pose selection as a Freeze Mask. I agree on the customized (numbers/segments) on the Pose tool lattices and Freeform Primitives. I've been wishing for that for years.

but this wouldnt actually change the mesh shape? this is displacement which cutting holes or have overlaps like shirt collars cant do , i suppose seam tearing would be an issue too ...  i know you guys work hard but cant we just get a traditional sculpting techniques .. because you cant manipulate the mesh proerly like you could quads , remeshing , poly modelling and refining , youre just reinventing the wheel but not as efficient its a wheel with 10 sides so it skips the road..

Try Bandicam, it is free

Is there a way to do this from within 3DCoat?  I don't normally do or make video's.  

pen radius is 0.014 ?

Please record video.

Yup, that's my work flow.  NADA happens.  

@Richard A.Hello! Please watch the video and tell me what I'm doing wrong. Запись экрана 2026-02-23 103905.mp4
