This was reported and fixed in the latest 2026 GPU build (03) 

This should be implemented now, in the latest 2026 GPU build (03)

It should work fine with older versions, because I have been using a SpaceMouse Enterprise for over 5yrs now and the drivers always worked well for me...except for the past year, as I mentioned before.

Have you tried any older drivers than 10.8.18? I thinking about trying the oldest drivers for my device, but I'm not sure if that's gonna go well with Windows 11 and also ZBrush.

3DConnexion changed their API over a year ago and thus their drivers since those changes have made it not work properly in 3DCoat. I reported this multiple times to Andrew, contacted 3DConnexion support directly and they said they had already reached out to Andrew about it, but because he is not working on 3DCoat full time now (due to the ongoing Russian invasion of Ukraine), I suppose he has not had enough time to work on it. Must not be an easy fix. I am currently using driver version 10.8.18.3698 and it works. What was changed is that for the top model, the SpaceMopuse Enterprise, it comes with built-in preset commands and radial menus...someone on their end spent a lot of time setting this up. This prevents the user from having to do all of this, manually, and the options contain all the tool icons + text, rather than just text alone. Nevertheless, there is some buggy behavior when navigating. I hope this gets fixed for the 2026 release.

ATTENTION: Existing fabric materials will be replaced with new fabric materials in the next build.

Windows, 2026-03 NS (Beta GPU Per-Pixel Painting) 3d-coat-5-27-2026NS.zip (Just unpack and run 3DCoatGL64.exe) - Retopo/Modeling Room: Added option "Switching Pen Mode to Rectangle After the Select Transform Activated" - New nodes are now created at the location where the right mouse button was clicked to invoke the menu—rather than at the location where the mouse cursor happened to be at the moment the node was created. - The "Soft Displacement" property has been added. This is a displacement effect designed to be used in conjunction with a normal map: Soft Displacement shifts vertices without affecting shading, and its impact on shadows is reduced by half; the normal map is then used to define the orientation of each pixel, ensuring correct shading. This feature is crucial for creating high-quality fabric materials. - Retopo/Modeling Room: "Polygon Tree" has been improved. Speed up work for large files. - Retopo/Modeling Room: tool Cap - bug fixed and improvements. - Node header default colors are now category-based (each category has its own distinct color). - Normal Map Support in Node-Based Materials - Fixed a crash that occurred while clearing the Node Graph in the Node Editor. - Fixed selection of multiple nodes using a rectangle or CTRL. - Added the ability to select multiple painting layers, move selected layers within the painting layer tree, and group, hide, unhide, duplicate, or delete them. - In GPUPPP mode, layer masks affect based on brightness, rather than exclusively based on transparency. - SoftDisplacement, combined with Sheen, can simulate fur, while FWSNormal defines its direction. To enable support for PPP texturing, "Show Displacement Mesh" must be enabled, and tessellation must be configured. - A tool for extracting MicroprotrusionsColor based on pixel brightness has been added to the PBRTiler extension.

This problem was reported here. https://3dcoat.com/mantis/view.php?id=2617 Thanks for point it up

Nah, that is not the problem, 3dconnexion app see different programs properly.

Will try that, but I don't think it will work. I've locked the horizon and it helped just a bit(consistency between views), but new issue appear - switching between ortho and perspective will often screw up the camera. Model will be far(I mean really far) in the viewport, or will disappear from the viewport, or camera will be zoomed in somewhere inside the model. That's with new 3D-Coat api for 3dconnexion. There is no such issues with 4.9 api, only the inconsistency between ortho and perspective view - 3dconnexion app doesn't have different settings between ortho and perspective, so if I set it up for ortho, it will work ok in that view, but will be screwed up in perspective and vice versa. EDIT: After playing around with new 3DC appi and 3dconnexion settings the same movement inconsistency is there too and sometimes all spacemouse navigation stops working in ortho view.

This ? If you have downloaded and are using the most recent 3dxWare driver, some devices lose the ability to have application specific settings and settings are global and stay the same regardless of what program you are using

Global speed won't work for me, the speed difference between ortho and perspective view is still there. How are you creating separate profiles for ortho  and perspective? I don't see any way to differentiate between ortho and perspective in 3dconnexion settings, it is just app specific, not view specific.

This ? Preferences > Viewport Does modifying these settings change anything ?

I’ve had the same issue with 3DConnexion in 3D Coat for a long time. The only somewhat usable workaround I found was lowering the global speed in the 3DConnexion driver and then creating separate app specific profiles for ortho and perspective heavy workflows, but it still feels inconsistent compared to Blender or ZBrush.  

And we NEED, NEED, NEED a DESELECT (SEAMS) BRUSH in the UV tools. On models without super clean topology and UV seams (ie. RETOPO via DECIMATION and Imported STL files, etc.), it can be a major paint in the bum and major time drain to deselect unnecessary seams. I know we can clear all seams at once, but in many cases that is going too far. There may just be one difficult part, while all the others are okay. Being able to DESELECT with a Brush would make the task much more efficient and a lot faster. I have requested this multiple times. The is also an open source UV packing utility that works way better than 3DCoat's packing. I requested that a long time ago also. It's really needed, and the UV toolset has really been somewhat neglected since Andrew added GU unfolding.  

Feature request: OpenGL to power its interactive 3D and 2D UV unwrapping viewports and tool operations. * speed up the complete UV editing workflows please

This happened to me, too, and I haven't been able to tell what caused it. However, when I renamed the MY DOCUMENTS/3DCOAT directory and then opened 3DCoat 2026, it created a fresh new one and that seemed to fix the problem. Of course I have to copy the custom contents of that older one, such as Smart Materials, Shaders, Stencils, Presets and such, but for now, that fixed the missing brushes problem.
