Bug Reports

Substance Painter 11.1.3 consistently Generates Thumbnails will scroll through assets, whether its materials, smart materials, alphas, etc. I have set the icon memory budget to 2000MB. I also used Environment Variables, SUBSTANCE_PAINTER_PREVIEWS_MEMORY_BUDGET, set to 24000. When scrolling through assets Substance Painter slows down significantly, where adding a material or smart material takes an extrememly long time to apply or load.5950x RTX 3090128 GB RAM All nvme SSDs

Accidentally overwrote my SPProject and my autosave won't open giving "Failed to Open Project", I have v 11.1.3 but the original project and it's autosave were created in a previous version in end of January. Need help opening this autosaved file since it’s a work file, it weights 3.21 GB so I'm sure it's not an empty scene because that’s pretty much the same weight the original project file had, just cannot get to open it, can anyone help with it?https://we.tl/t-kklfzFDR77 wetransfer stays up for 3 days but I can update it after it expires if needed.Really need to open this file!😫

Hello. recantly I bought mobile device with new Ryzen AI MAX 395+ including 8060s iGPU. Unfortunately I encountered problem with GPU accelerated baking, CPU only baking is working perfectly fine. When I click bake, programs starts to proceed with baking although no progress is being shown. After a while baking finishes, but nothing changes in terms of viewport ouput and when I try to interact with it nothing changes ,viewport become static. I can freely interact with UI though like nothing ever happened. When I check the log file it says that baking has actually has been completed but few lines above there is fatal error saying:[ ERR] <Qt> "[DBG ERROR][Main]" "[SALpp] [Level:FATAL] [Component:DeviceLost] GPU Device lost: driver crash or TDR"I tried to increase Tdr value to as high as 180s for both keys, I also was testing it with different VRAM allocation values, up to 48gb (16/32/48gb, 48gb being max as my total system memory is 64gb of ram). That haven’t resolved the problem th

Inside Painter, MacBook trackpads only control zoom when two-finger swiping and nothing else. Swiping zooms, spreading fingers does nothing, shift+swipe does nothing.I would expect it to work the same as the 3D view inside Designer, in which two-finger swiping rotates, shift+swipe pans, and finger-spreading zooms in/out. That’s how all other 3D applications I’m aware of also handle trackpad navigation, so this doesn’t seem like an intentional design choice.

Hello. I added some plate polygons to add some flair to the model. Then I added a color material to the plate polygons and baked it again. However, doing so caused the previously normal drawing to collapse.I checked it several times, and it was the exact same model except for the plate polygons, and there were no problems with the color material. Therefore, I consider this a bug. 

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!

Stencil: after draging a alpha texture into the slot i try to draw on a paint layer that i created on a black mask. the preview of the texture works and i am able to scale rotate and move the alpha. but when i try to draw it on the mesh nothing happens. weirdly enough, when i draw on the UV/2D view it works. Its only broken in the 3D view. Projection tool: when i drag a texture into the stencil it does not show up in my paint buffer (the buffer just stays grey) so i dont see what i project but when i left click, it actually project the thing onto the mesh. So just the preview is broken. 

In Texture Bake mode, even if the model’s geometry is perfectly flat, if there are polygon edges or UV seams within that flat area, the curvature bake still produces white lines.Please let me know if there is a proper setting to avoid this or if it is a bug.If it is a bug, I would like it to be fixed.Thank you.

Hello there,My team works on building assets for a AAA project, and part of our pipeline involves baking AO at a max occluder distance of 200 for consistent AO results across buildings.As of Substance 11.1, we can no longer set the Max Occluder distance beyond 1. This is disrupting our workflow and requiring us to roll-back to a prior version. 

Hi I am using substance 3d painter to paint over my 3d model. I can only paint one object at a time (unable to load UDIMS) and the texture maps are not fully fitted into the box when i upload the export jpegs into blender model so the model doesnt come out great.   so two issues1. my uv maps arent fully fitted into the box2. I cant load UDIMS and paint across the 39objects that are attached together this is the model. I think its because the objects are touching and thats what happensI mainly want to paint and not dive deep into modelsI opened the model in opengl, directx not sure what the issue is. will include the model obj attached  

hi guys!I'm on a AMD RYZEN AI MAX+ 395 w/ Radeon 8060S, 3000 Mhz, 16 Core(s), 32 Logical Processor(s) wth 128gb of memory vram.I oticed that the Stylized filter at 4k makes Substance Painter freeze or the viewport will become unrespnsive (only the vieport, the menu are still working) . It only happens at 4k, at 2k the same filter works butter smooth.Usually, with 128gb of vram I'm able to use Painter without issue, it's actually very fast.Thank you!Max

yesterday everything was fine. today i cant make a project, access shortcuts, or edit and update old project. i cant access easy mode. i cant find core files, ive reinstalled the aplication 3 times with no fix. each new install has the same issue. im using the steam 2025 version. how do i fix this

※ Sorry if there are any parts that are not correct as I am using a translation tool.I am always lagging when I rotate or move by entering alt + LeftClick , RightClick , MiddleClick keys in the latest SubstancePainter. I have been suffering from this problem for the past 6 months.I thought it might be a problem with my computer, but it is not.Old PC i7-12700 rtx3070 mem64gbNew PC Core Ultra 7 265F rtx 5070 mem64gbPC at work similar to the above specs and the same phenomenon is happening on all computers.So I installed Substance Painter 2022 (8.3.1) which I bought on Steam and tested it, but there was no problem at all. (Attached video)I also installed 8.3.1 with AdobeCreativeCloud and had no problem.I do not know how to solve this problem. What should I do ...Translated with DeepL.com (free version)

So I am running into the following issue when I am trying to create some textures for a personal project:  This glitch is happening on all layers and all channels, and there is only one texture set I am working with.  I have tried closing out the project and restarting, and I have also tried to remake this project, with the same results

As mentioned in the subject , for some reason I cannot add an anchor point to the group. Substance 3D Painter, version 7.4.3Build 1610 - 7fb11e93372084443976065c4dd47f45a8f0940c

Version: Substance 3D Painter 2025 - Whatever is live on Steam right now.Platform: PC, Windows 11Reproduce: Bake all maps for a symetrical angular hard surface model. Apply painted steel smart material. Observe that edge wear is applied asymmetrically, and that the curve map is generated assymmetrically.Expected result: Curvature map is generated symmetrically for the model regardless of UV island positions.Actual result: Curvature map has small differences despite being largely correct. I am encountering an issue where auto-baked curvature maps are generating inconsistently on a symmetrical model. This has resulted in the issue below, where edge wear is asymmetrically applied on the back of the model. Red is where it has applied, blue is where it has not.I believe this to be caused by the curvature map  baking improperly. This is the curvature map of the same area, and as can be seen from the texture dilation, one side has generated a lighter curvature line, while the other

Hi, I've been trying to bake some wings that are slightly thin, from high to low poly, but this error occurs, some strange straight lines or wrinkles appear on the edge for some reason.  

1. Painter should be better at processing imported bitmaps - it should have an option to preserve original image proportions if they are not square.2. After undocking a window, its numerical fields sometimes do not work properly.

Hi, substance painter on my laptop with Nvidia rtx 5090 24 GB vram, Intel ultra 9 275 Hx CPU and 128 GB ram, does not work, runs between 2 and 4 fps, impossible to work .Hello, I'm using Substance Painter on a laptop with an NVIDIA RTX 5090 GPU (latest Studio driver installed). The software starts, but the viewport is extremely slow and the GPU isn't being used correctly (verified via GPU-Z and Task Manager). I've already tried the following: - Forcing GPU usage via the NVIDIA Control Panel and the Windows graphics settings Clearing the shader cache - Adjusting TdrDelay in the registry - Testing both the Game Ready and Studio drivers Substance Painter shows GPU usage of only 0-4% and isn't effectively using either the video engine or the VRAM. Is there a planned update that officially supports the RTX 5000 series (Blackwell)? Or is there a version that's compatible with this GPU? 

Hi, my student license to Substance 3D products ran out recently and I was hoping to renew it but I recently changed schools. When renewing it, I mistakenly used the email of my last school which I don't have access to. After trying again with my current school's email, Identit-e gave me the message:"DENIED - You are only allowed to redeem 1 discounted product every 365 days. Our records indicate that you have already redeemed within the past year."even though I have not redeemed the license because I can't access the email.

Using a scratch stencil, I see that some scratches show up properly oriented, some seem misaligned, and some seem tiled (even when tiling is disabled). How do I properly align the stencil properly so the effected area is more predictable?

I have test the GPU, worked with AMD Support AND support with the manufacturer and a PC technical agent.All found the fault to be with Adobe Substance Painter.I have been able to bake 4k textures for my projects but I can't even paint or do anything because the program with lag and become non-responsive when I interacte with the viewport.I have been trying to get help from Adobe Technical Support since three weeks ago and recently tried to get help here. I'm posting in hopes of getting help.All other support team options have failed and I when I tried to go into a call and have assisstance, the person didn't seem to know what to do. Please help. I don't want to pay for a subscription to something I can't even use.If there were other options I would have never bothered with this buggy program and lack of support. I have evidence to support that the GPU is fine and I can provide dxdiag and sysinfo if needed.
