Confirmed For this type of task is much better to use Add/Split tool

Is this reply related to your current issue ?  

What are your snapping settings set to? Here's a GIF example of what I mean:

Doesn't work at all, results are even worse. Run brush along projection with higher position sampling kinda works(not alway, it often makes weird hooks on the end of curve), but Brush along curve absolutely not.

I figured it out; it's because 3D-Coat uses the device's color profile (instead of its own), so if that profile is wrong, the issue happens. The solution is to, inside of Photoshop, go under Edit > Assign Profile and select the incorrect profile your laptop was using, then when done with doing final touch-ups to the texture in PS simply export it and PS will convert it to a sRGB making it look correct in Sketchfab. To prevent this from happening again in the future, make sure the device's color profile is correct before texturing.

Hi, in the 3D Coat Texture 2025.17 version the AO calculation gives very strange results, and in my opinion incorrect, compared to the 2024.32 version I attach the screenshot with the differences. Thanks for any suggestions or addressing this bug Giobianco

Hi, with 3D Coat Texture version 2025.17 I have problems when I try to open new files, when I click on "Paint UV Mapped Mesh (Per-Pixel)" and click on the folder icon to open a file, nothing opens (the Windows window with the directories does not appear) but the selection menu simply disappears... and to be able to load an FBX or OBI model I have to go to the menu / file / import / model for Per Pixel Painting. Thanks for any suggestions or addressing this bug   Giobianco

Ok, so in the latest version of Reality scan they have added the option to export vertex colors either in linear or in sRGB. I suppose that takes care of the problem even though it could be nice to have an option in 3D coat to gamma up or down.

When I cut with knife tool, the mesh result follow the silhouette and also snap to the underlying sculpt... what I am doing wrong ?

I've confirmed this and I agree that the resulting geo should also snap to the underlying sculpt.

Using this settings, I can't see any problem

Some issues with brush strokes - it's ok in freehand mode, but it's absolutely screwed up when using curves. Video is recorded in 3DC 2025, but it's the same thing with 2026 version.  

Quote fragment from Wikipedia: "... executed client-side, by the website-user's computer via the user's web browser". In practice, it means no installation is needed, executes on any platform/OS, and users always get the latest build. The theoretical 3DCoat on the web could have a minimal set of essential/core features. Users access it through their web browsers to process their local assets. The question is, is there a need for such 3DCoat on the web, and what essential/core features should it have?

Hi It's been a while since I last posted here, but I have a concern regarding the Knife tool whilst retopologising. I'm not sure if there's an option I need to adjust, but is there any way of getting the Knife tool's cuts to influence the low poly mesh so it conforms to the reference mesh? In other words, like the Split Rings tool, when you add a loop, it makes the low poly mesh conform to the reference mesh by pushing the loop out and matching the curvature and silhouette. All I get with the Knife tool are the cuts, but the low poly mesh remains flat. Thanks

It really depends on what functionality will it have. That should work from within browser?

Hi to all. I am doing only hard surface modeling, working mainly in Paint Room - UV Room and only for separating the model in the Modeling Room. Models themselves are created in Blender, right now in Version 5. Right now I use 3DCoat 2026.1 I have been using 3DCoat for some years now on a daily basis and to me it sounds funny what is written on the topic of this forum section by Carlosan, that more detailed information is needed to solve problems. I do have high resprect for Carlosan, he is really doing his best in support, but, in my opinion, forwarding the problems to the developers does not bring any results. I have been reporting multiple problems in Paint Room and UV Room over the past years. All of the problems have been checked and confirmed as faults by different high ranked testers and been reported to the developers. The problems are not minimal small side effects that are not working correctly, the problems are fundamental problems. None have been solved up to now! I wrote a personal message to Mr. Shpagin, the lead developer of 3DCoat. I dared to do this, just because Mr. Shpagin wrote in the forum: "...just in case you have problems and get no solution for it, contact me in person" BUT, not even an answer to my mail. So even though I´m sure I won't get a solution for the problem, I will post it here. The model is created in Blender 5. Imported to 3DCoat by per Pixel Paint with Auto mapping In UV Room I separate the corresponding UV Islands to separate UV sets. After separating a part to a new set, I do an "unwrap" command and "apply UV set", switch to Paint Room, check if the different UV sets are correct, return to UV room, and then I continue with the separation process. After some time this strange effect happens. As seen on the pictures (attached),  the UV Sets in the UV Room are all correct, but one of the UV sets in the Paint Room is completely broken. You may swith back to UV Room, do an unwrap, do an apply UV Set, return to Paint Room, confrim the change in the UV Room, but nothing changes, the UV set is broken and stays broken. There is no way to correct it. Result .... restart your work, lose more time. Pictures Bild 1 and Bild 2, show the different rooms: UV Room and Paint Room. You may check the memory consumption in the bottom line, as well as the time and date stamp, just in case you think that I want to fool someone. My system can´t be the problem, there is enough memory, enough harddrive space, all these things have been checked and confirmed within the last years of error reports. I clearly understand that solving a problem like this is nearly impossible, because there could be any number of problems with the model itself. But the model  is checked in Blender for manifold problem or any other related problem and over all, the problem has nothing to do with this model specifically, the problem appears nearly every time I do work with models with a high polygon count. So, maybe the problem was already reported by someone else, maybe there is already a workaround, but I don't think there is a solution and my experience shows me that there probably won´t be a solution, either.  Another frustrated user of 3DCoat Best regards Walter PS: I´m well aware of the terrible situation in Ukraine and my heart is heavy when I´m thinking of the daily threat to the Ukraine people. 

Try exporting trough Textures Menu   same result ?

It is for Sculpt Objects (Nodes Workspace), but not just yet for Paint Objects. They are preparing it for the 2026 release and working all the bugs out before dropping it to beta. Should be anytime now.
