Check this option Try changing this: Ghosted must be set to Pick & Act

I really don't get how I am supposed to enjoy this software when there are bugs all over the place. 

With carve tool, I have previously drawn on the blue ghosted object and saved the file. Now when I opened it, and started drawing on the hands, it draws through! Why is 3dcoat so god damn inconsistent and full of bugs?  It feel like I am the god forsaken beta tester.  Intro.3b

alright solved it, turns out my documents folder was set to read only by windows ransomware protection

Hi, some materials paint fine on MacOS but many are just paint black, not sure if it's a user error or a bug.   here's the link on discord showing the video   https://discord.com/channels/680168650791321648/680168650791321774/1555967632686063806   cheers,   Kuzey

Oh, by the way In few newer versions of 3DCoat textura same issue I described here also present, I tried only Stable releases  

Hi! So I've been working on 2025.11 version since it was first released and payed today to have further one year update. I am constantly having issue with windows layouts resetting to default, so I thought update will fix it. And this partticular issue, well, was fixed.  On the other hand devs changed something critical about viewport or smth, that is not allowing me to work comfortably with Alpha cutout anymore.  My main go-to setting is showing lowpoly model.(6 on a keyboard)  See, it enables backface culling and getting rid of weird rendering way where borders of alpha texture showing all geometry below through them too. That being said - in 2026 releases (and I tried few of them) hotkey 6 is not working. Moreover - changing options in View menu does nothing (Yes im aware of linear texture filtering and backface culling option there) - wireframe on mesh is not turning yellow, as it was before on 2025 release. This leading me to another thing - when I am uploading my mesh - it has white aliased borders, with no texture applied at all. I dont know what the issue here with Viewport, but changing its settings does nothing too - it just broke. Below is screenshot of model, with Layer 0 disabled, no textures applied in Flat shading mode. Thode white boders are being on top of everything is just annoying..  Same mesh on my 2025.11 Textura relese have no such problem, Low-Poly option in Viewport working correctly. I dont know what changed, but feels like I will stick to my 2025.11 release for another year, cause updating on newer one is just not working for me and I have spent half of day already trying to find whats wrong. It is sad, that paying for update is kinda useless this time, but I hope this post will highlight one of a problems for people who works on pipeline like mine

not sure what you mean... If you are talking about Focus on brush command - it is still there, in the activity bar. You can assign shift+z on it without any problems.

I find the "Online" App link is old and doesn't work well. Ive copied the py code from the 3dcoat "Install App Links Blender 4x) to the Blender foundation file for 5.2 - where ever your 3dcoat app link is and pasted over old code. Never needed to reset the location of the exchange folder. The folder mentioned by Dmitiriy Nos works. When I upgrade to 3dcoat 2026.24NS the Blender app didnt update.  

@JulianC:\Users\...\Documents\3DCoat2026\Exchange is the most reliable path for exchange. Specify it in Blender settings as well.

Problem with multi layers is you can’t save the material to be used later. One needs to build all nodes in one layer so they can be saved and used again. Hopefully this will be fixed in future development of nodes.

Which is the correct Applink Exchange Folder for Blender? My AppLink does not work, I am not able to send or receive objects from and to 3DCoat/Blender. I am using 3DCoat for years and AppLink sometimes work, sometimes it does not, depending on the current version. Right now, I have three 3D Coat folders in my Documents:  - 3DCoat - 3DCoat2026 - AppLinks All of them include exchange folders. This is incredible confusing and I have no idea which folder path I should use to make the AppLink work. The documentation about the AppLink is outdated https://3dcoat.com/documentation/manual/getting-started/app-links/blender-applink/. I just want to send objects from Blender to 3DCoat and back again. Could someone please help me out? I am using Blender 5.2, 3DCoat 2026.24NS and AppLink Version 5.0.0
