Bug Reports

When creating a proyect using a template that has a shader asigned to the texture set, it only applies that shader to 1 of the texturesets the imported mesh file has, leaving the rest with the default asm-metal-rough, when it should apply the shader chosen in the template to all texturesets.Attached gif shows how that happens even with the default PBR with Alpha Blending template shipped. 

Hi everyone,I'm new to Substance Painter and I'm having trouble with my custom mesh. I can apply materials like roughness and metallic just fine, but I can't paint directly on the mesh or use masks — nothing shows up when I try.I’ve checked the UVs and they seem correct (everything is in the 1001 tile, no UDIMs). I also made sure to disable automatic unwrapping when creating the project. The mesh loads correctly, and I can see it in the viewport, but painting just doesn’t work.I’ve tried using paint layers, different brushes, and switching view modes (Material, Base Color, etc.), but still no luck. Everything works perfectly when I use the default mesh (Meet Mat), so I’m really confused.Could this be a shader issue or something with the texture sets? Any help would be greatly appreciated!Thanks in advance

Hi,The path tool only appearing across texture sets when using filled path, but not when using paint along path. Example on the pictures:

Hello!Ive been working in a Substance Painter file with no issues till recently. Whenever I wanna edit the file set to 2k, it crashes. It worked fine before, not sure what has changed. This issue doesnt happen when the file is set to 1k or below. I have a strong Razer Laptop with an RTX 4080 and have worked on very heavy files before (I work in Video games.) I hope there is a solution to this as I need to export my file in 2k textures! I've attached the log.

 I tried all formats, sizes, bits, paddings

Hello. I am using Substance Painter 11.0.2. I know it has an update, I haven't downloaded it yet because I don't want to waste my bandwidth downloading an update only to have to roll back to before 11.0.2.  It seems the Substance Painter in Windows Mode is too big for my screen. I'm using a standard 1080p resolution screen on my laptop.  How do I fix this?

Hi everyone,I’m having trouble launching Substance 3D Painter 2025 (Steam version). When I try to start it, the splash screen shows up, but the main window never opens.

It gets stuck every time I click on the texture set section to adjust the resolution or look at other models, and all versions of 11 I tried with the same result. Who can save me?

Hi,I recently upgraded to a new ASUS RTX 5090, and I’m experiencing an issue with Iray in the latest version of Substance Painter.All system and GPU drivers are fully up to date.When I set Iray to render only on the GPU (disabling CPU rendering), the viewport freezes and displays “Iray warm-up” in the bottom-right corner. The program doesn’t crash, but the rendering does not proceed — the image remains frozen indefinitely.If I re-enable CPU rendering, the frame immediately unfreezes and Iray starts rendering normally.I have tested this with both the latest Studio and Game Ready NVIDIA drivers — the issue remains the same.This problem did not occur with my previous GPUs (GTX 1070, RTX 3090, RTX 4090) — they all rendered fine using GPU-only mode in Iray.Could this be due to Iray not yet supporting the RTX 5090 architecture?Is there a workaround or upcoming update planned to support this GPU?Thank you in advance!

mac os 26 Developer beta5 Steam Substance  painter 2025 In the video, both blender and double-click to open can be previewed normally. When importing sp, a strange stretching appeared.   

 mac os 26 Developer beta5 Steam Substance  painter 2025 1，The window is always incomplete.。2，Maybe it's not a bug, it's a very obvious jaggedness, and there are still obvious jaggedness in 2025. You can find a solution in the blender code.。3，It keeps prompting "Turn on video and audio recording" – I've already turned them on. The translation comes from ai. Thank you for your efforts. I hope the mac version will be better, such as gpu ray tracing, etc. 

When I create a new Tab from a Saved Search, and position it where I want it to be, it is forgotten when restarting Painter. For example, I want to have an undocked tab of my brushes on my second monitor, but every time I restart Painter, I have to do the entire process over again. If I dock the tab in the main application window, it remembers that, but I want it undocked on my second monitor. Saving my UI Layout doesn't help. 

In Painter 11.0.1 I'm experiencing a bug where the UI is updating incorrectly. If you have a scene with multiple shader instances in it and have a textureset active using a shader instance that is not the first one in the combobox there is a problem. If you switch to a debug shader in the viewport (like "Normals"), the Shader Instance widget will go blank, showing that no shader from the scene is currently used on the textureset.  When you set the debug mode back to "Material" the expected behavior is that it returns to the original Shader Instance that is assigned to the current textureset.  However what actually happens is that the widget updates to just show the first shader instance in the combobox list.  It doesn't actually break shader instance assignment, but the UI does not match what is actually assigned to the textureset. This is causing some serious problems for us as we have a tool that watches the contents of this widget to update our custom U

Hi, So the path tool in the newest version of substance painter is bugged now as it won't allow stitches to loop across the full path if the size is too small. This was never an issue and is causing a lot of extra work for us now to fix. Any ETA on a hot fix for this?

On the newest version of Windows 11, with the newest versions of Creative Cloud and Substance Painter installed. This is my first time installing an Adobe product and I've run into an issue where Substance 3D Painter gives error code 205, says "Substance Painter has encountered and issue and must close, you will not be able to use Substance Painter at this time" and crashes every time I try launching it, sometimes taking longer than a minute to do so. Both Substance Painter and Creative Cloud are the newest versions, and this issue doesn't occur for Photoshop, only for Substance Painter. I've tried uninstalling and reinstalling, as well as installing it onto a different drive with more storage free, I've tried having no other apps running, I've tried signing out of Creative Cloud, restarting my PC, then signing back in (About a dozen times now), as well as signing out of CC, then restarting, then signing back in through the Substance Painter app instead of the CC app, I've tried cleari

I am getting this message periodically and time consumingly.  "[Project management] Save failed - this is unusual, check previous messages for more information" I can't share the file as it's covered by an NDA, but I see no reason that the file should save fine one minute and not the next. This program is supposed to save me some time texturing and I'm spending half of it dealing with nonsense like this.  Sorry for my irritation but I just lost a couple hours work due to this, as I also had to disable the Autosave function as it was taking just over a minute per save, which is not conducive to good workflow.  Anyway, I appreciate any assistance.

Hi, I have a very inconvenient issue/bug with my Substance Painter.From a random point, my file doesn't want to save anymore, even increments.I've allready lost a day of work with this, then the next day I didn't had any issues, and today here we go again, it stopped saving at 11:06AM. (It's now 11:50)The auto-save are not working eather.He you can see some screeenshots: Apparently, the autosave stopped working at 11:06AM but the regular "crtl+s" never worked as the last save is indicated the day before (see file explorer screenshot) My substance Painter is up to date, my disk have space in it.Disk ref: Crucial P5 Plus 2To (ssd M2) Thank you in advance for helping out with this !
