Substance 3D Painter

After updating to version 12.2.0, I received a notification upon launching the program stating that I needed to update my graphics drivers to the latest version. I did so and then launched the program; however, issues arise as soon as I try to work with masks or layers—the program itself remains active, but the viewport stops responding. I am using an RTX 4070 with the 621.01 Game Ready driver.

Hello! I am trying to Run Adobe Substance Painter 2025 on my Macbook, through Steam. I have tried everything to make it work yet it continues to crash on the startup. I have submitted a Log.TXT to see if it can be diagnosed. System Specs:  (Image removed)

So i posted this a while back before but the Post has been removed for some reason…. i guess because being inactive on the post. but yeah this happens when using the Pen Tool more you use it. adds artifacts to your Height and the only fix for this was to Down Grade to 2025 11.0.3… Any Higher that that Version the Bug still remains there…… shocking its still there in 2026 Video example i made for the old post  

Since upgrading to 12 and above, I’ve had nothing but graphical bugs and corruption with my textures in the viewport. Previously, in 11 and below, I’d never encountered any of this. Admittedly, I am using an old graphics card still - the GTX 1080, which is using the latest drivers. I’ve tried uninstalling Substance Painter and reinstalling, but it doesn’t fix the issue. I’ve also tried disabling the Sparse Virtual Texture in the settings.The video recorded and attached demonstrates perfectly the kind of graphical corruption I keep getting. At the moment, I’m using 12.1.5.Graphical Corruption

Error example:[BakingProcess] Can’t create a resource from the baker result: tile (0,0): couldn’t find surface in resource world space normal *name of asset*When starting a new file, baking completes as expected without any error. But upon making shader application or UDIM lay out changes to the asset in Maya and re-importing the mesh, baking fails on all mesh map bakes.Error seems to be stemming from UDIMs changing texture sets/UV coordinates.Tests/Attempted Solutions:1) Not moving any UV’s, and only applying a different shader in Maya (Error)    • Seems to not matter if texture set stays enabled or gets disabled in Painter2) Not applying a different shader/texture set, and only moving a UV island to a new UDIM (Error)3) Making a new Painter scene and using the mesh with the changes (Bakes as expected)4) Tested with different assets, all give the error5) Tested with Substance Painter 11.0.3 (Bakes as expected)6) Instead of using “Re-import Mesh”, I tried going to Project Configuration

Close Painter with the project still open.ResultPainter crashes during shutdown and the crash report window appears. It happens on every exit.

Problem with baking rounded objects (but this apply to many other cases).Example with this Cactus Sculpt. Here is one layer of the upper flower _high, viewed from side and from above: Automatic cage (experimental), works amazingly well for tons of complex objects, but not for some simple ones like the example above. If I bake with Cage type set to: Automatic (experimental), it feels like the Max rear distance is infinite and catches anything behind faces. If I bake the more traditional way with a hand-made cage mesh, or with the basic Distance-based Cage type, it works perfectly fine: So basically, there’s an issue with Automatic (experimental) Cage type. The automatically calculated “Max rear distance” cannot be controlled by the user, and the one that’s calculated automatically seems to go indefinitely, baking everything on the opposite side of my polygons normals direction.Of course there are tons of workarounds. But it just doesn’t feel right. Esepcially given how much of a revolut

Tested this on a dummy file and i'm getting the same issues, images attached below. So I just built a new PC and started working in substance again only to realize some of my bakes are completely broken. AO in particular has these weird artifacts appearing all over the model. The model and UVs are fine and my GPU drivers are updated to latest. At my wits end trying to fix this. PC spec is 7600x3d and 7900xtx with 32 gigs of ram. Windows 11. I'm using Substance Painter 2022 Steam Edition. 

If I press the Tab key, it’ll hide the UI like it should, but if I press it again, the program crashes. It happens in every 12. version, pls fix

Since 12.1 (this is 12.1.1) the VRAM usage of Substance Painter is crazy. There's another bug report about performance issues but for me it wasn't clear if it's VRAM related.What happens:While working on a very small scene which only uses like 3GB of VRAM it skyrockets to the max in the matter of minutes while working on it.This is 100% a memory leak and happens as well with version 12.1.1My system is nothing special, Win 11, 64GB, i9-9900K but what makes it a bit more special is the fact I have 2 GPUs, a 3090 and 4090 both with 24GB VRAM.I tried to force using the 3090 using the options inside Windows Display > Graphics options but that doesn't help, it only switches the issue to the 3090. I'm currently at the Nvidia 610.62 Studio Drivers.If I quit Substance Painter while it hugs the 24GB it will roughly empty 12GB and after like a minute it gives me back another 10GB of VRAM.It also doesn't really matter what I do, the screenshot attached is a storyboard where I only hide/unhide m

1.Open new project2. switch shader to pbr-material-layering or pbr-material-layering-10-mats3. assign all materials to any material that has distinct normal map(e.g. Stylized Wood Bark)4. Normal map is visibly blank/totally flat - buginterestingly enough, while no materials in the basic library work, some materials from substance 3d assets do work, this one for example :https://substance3d.adobe.com/assets/collections/1b1c286f3c9fd90f5aaca37388d9c7371c4d0753/asset/4186eaeaf99dc95f06c4cc2e164ce0fb5d3c3150 

The Steam perpetual version of Substance 3D Painter 2026 has significant lag and stuttering every few seconds. I saw patch notes claiming this has been fixed, but it has not been fixed on the Steam version it seems.Specs:OS: Windows 11GPU: NVidia RTX 5090CPU: Intel Core Ultra 9 285KRAM: 64GB DDR5Storage: 2TB+ NvMEThings I’ve Tried:ReinstalledClose Logitech lamp array servicesRestart PCForce Substance to use dedicated GPUAny way that Adobe could look into this issue would be great. It’s negatively impacting my ability to work.
