Bug Reports

Substance Painter 2026 cannot perfectly mirror brush strokes.When performing UV mirroring, asymmetry occurs. I tried using the mirror function within the filter, which works perfectly. However, the object contains a small portion that is asymmetrical, so I wasn't initially considering using the filter mirroring.

Run painter in cli with --help, --enable-remote-scripting is missing.Run with --help-all does nothing like what it claims to be doing.Documentation https://helpx.adobe.com/substance-3d-painter-python/api.html does not contain any mention of remote scripting.It is only found on https://experienceleague.adobe.com/en/docs/substance-3d-painter/using/scripting-and-development/scripts-and-plugins/remote-control-with-scriptingAnother bug, but that is related to this site. Editing the “Describe your bug” essentially creates a new one so anything users have written about a bug is deleted. 

I’m creating a new post about this topic because everywhere I see theres no solution. I can open the file, and I can export texture, but I’m not allowed to modify it since if I do anything it starts to load and never finish, ending up to be closed by ctrl alt del. I’ve seen in way too many posts, for some years ans this bug is still nowadays all strong. Whats the problem with this software? its a industry standard going with the same bug FOR YEARS. This is just ridiculous

Hello, I purchased Substance Painter 3D Steam Edition and installed it on Arch Linux (GNOME) and on the latest 64-bit version of Ubuntu LTS (GNOME). I am encountering an extremely annoying issue with the software’s color picker. The bug manifests differently depending on the distribution : For Arch Linux – GNOME  : When I click directly on the color, the widget does not appear at all—the click seems to do nothing. When I use the eyedropper tool, the screen turns black until I select a color (which ends up being black since the screen is black). After that, the screen returns to normal. This makes the software practically unusable. For Ubuntu LTS (latest 64-bit version) – GNOME : When I click directly on the color, the widget appears correctly and works as expected. However, when I use the eyedropper tool, the same bug as on Arch occurs. Note : When I refer to the color and the eyedropper, I mean the main color picker as well as all the settings used to modify a material (textures, etc.

Hello!After updating Substance 3D Painter to version 11.1, I encountered a problem: the baker stopped working.What happens:When I try to start baking, the program completely freezes and becomes unresponsive. I have to force-close it through the Task Manager. The issue occurs every time, even in a new project.My system:Windows 11GPU: NVIDIA GTX 1080 TiGPU drivers are updated to the latest versionWhat I have already tried:Restarting the software and the PCCreating a new projectUnfortunately, the problem persists.Could you please advise what I can do to restore the baker's functionality? Are there any known conflicts or recommended settings?Thank you!

The stencil display is low quality; this happened on its own—I didn't make any changes to the settings. The texture resolution for the projection is 4K; the texture resolution in the scene is 2K or 4K (this doesn't affect the display). Viewport scaling doesn't help. Substance 3D Painter, version 11.1.3Build 5196 - 464cbc573e735fa706a879f3a29107b6fc9865c7

It is not really a bug, just annoying for years: I am super quick with mouse and pen → I click into a textfield or drag my selection around the text I need to copy it and jump instantly to the next action. This works for all programs I know (Windows, 3 screens btw).Not in Substance Painter (and I think Designer has the same issue). If I click into a textfield to enter a name for a layer or material, or set a slider to an exact value I always need two or three attempts. Because I am so fast with my cursor that when starting to write my mouse cursor is alreay moved away from the text field. Or I use my Wacom pen: Click into the textfield with the pen, raise it to type, but raising the pen is a movement that drives the curser a bit away from the textfield. So it losts focus and I type into the void.Same for selecting text: If you move just a bit to far away from the text the selection ends and you can copy what you want → the clipboard is empty. I am often so fast that I recognise it when

Windows ink is a menace. Can we please get rid of this? I just don't want to be drawing and moving a program in lag with windows ink causing this much issue.

Hello,Version: Substance 3D Painter 12.0Issue: When I modify an existing Color Selection mask on a folder (by adding or removing a picked color), the Base Color of the material inside that folder disappears. Other channels (Normal, Metallic, Roughness, etc.) remain unaffected.Steps to reproduce:Bake an ID map from vertex colors (e.g. red, green, blue areas). Create Folder A with a black mask + Color Selection picking red and green. Create Folder B with a black mask + Color Selection picking blue. Place fill layers with materials inside each folder. Base Color displays correctly at this point. Remove red from Folder A's Color Selection, then add red to Folder B's Color Selection. Result: The Base Color in Folder B no longer displays for the newly added red area. Normal, Metallic, and other channels display correctly.Workaround: Deleting the Color Selection alone does not fix it. Deleting the entire black mask and recreating it from scratch (black mask → Color Selection → pick colors) re

Heyhey, guys! I am a bit frustrated right now because my Painter keeps crashing whenever I try to open a certain file. It's not just that file, though, but also all autosaves of it (going back about an hour before the last manual save). It opened just fine earlier today and I had no issues with it at all so far. An older version (basically without actual progress, though..) opens without issue as well. So far, I have restarted my PC, updated my graphics driver, made sure that Painter launches using my GPU, moved the file from my external hard drive to my local one and tried to run Painter and open the file without anything else running at the same time (to make sure all resources are reserved for Painter). Nothing has helped. It just crashes about a second or two after I try opening it. There was one instance where it took a few seconds and it looked like it might be loading the file, but it just crashed again after a few seconds. I didn't even do anything overly fancy.

Why does Painter insist on going back to base color from mask mode when I switch layers? Working in mask mode is often the quickest way to see which surfaces in a complex scene have which materials, but every time I switch layers it jumps back to base color. This is really disruptive to workflow. With a complex scene with many layers, keeping track of material assignment is already extremely difficult in Painter and it's important to try to avoid overlapping materials. So masking is very important. Working in mask mode to quickly check thru all layers in this way would really be the fastest method... except Painter jumps out of this mode with every layer change, and all the associated redraw time that this entails. Think I really might have to learn Mari.....

Hi! I have a problem.My Autosave plugin settings are not saved.I am trying to configure this plugin, but after I close Substance Painter and open it again, all the settings of the Autosave plugin are reset to the default ones.What could be the problem?Windows 11 operating System.

I recently updated to Substance painter 12.0 today, updating one of my projects I was working on.I then go to export the textures to files, same as I’ve done for years on previous versions and..it does nothing. Just sits there, no files generated, just stuck on computing textures results.Have tried reinstalling, no change. Was working fine on the last version.

Substance Painter 12.0.1 I have this issue where after baking all the maps look fine except world space normal (see first screenshot). The mesh is triangulated in Blender before export. And I have re-imported the FBX to blender to triple check this. Must be some baking bug in painter? Not having a correct world space normal is really messing up all the smart materials, not sure how to fix it. World Space Normals in Painter Blender MatCapAttached my exported FBX if you want to test it.

Hi guys, I'm having an error when baking any model in the software. It creates artifacts on the AO map that are the same in all models. I tried to find a solution for this, but I was unsuccessful. Could somebody help me?
