We’ve noticed that Roughness map (Specular Roughness) fails to export when packed with other maps. The only solution we found for it to export properly was by first using document channels export preset, which seems to be loading the texture into memory, THEN exporting with any other preset.

When I use a FBX file it uses correctly the Material Name that is assigned to the Mesh:Assignment in the Maya Model file:When I use a USD file it uses the Shading Group not the Sader as a Name: I checked my USD and the Shader is still assigned:  It would be great to have only one way of naming here either for both the material name or for both the shading group name, but mixed is confusing our pipeline when exporting the texture files. Thank you!Best regards,Timo

Windows 11 | Painter 11.1.3 | Nvidia GeForce RTX 3080Ti | 128 GB RAM | ADM Ryzen 9 5900X 12 Core When I create a new File I set a OCIO (Custom, ACES 1.2 or ACES 2.0 doesn’t matter). Then I load in external texture files and set their Output color space. It doesn’t matter if I set this manually or automatic via OCIO rules All good and works like that:After saving and reopen the file I lose all the “Output color space” OCIO rules/settings. It displays not compatible and only the defaults are available. When I check the Project Configuration it is still using the correct OCIO file and there is also no Error/Warning in the LOG: Does anyone else has this issue? It is a critical Bug in our case because textures load wrong and are not correctly exportet. Also it is very confusing. Sadly we can’t go to Painter Version 12 yet because of the python version switch. Best regards,Timo

Hello! It's more an issue with Steam pricing, but Valve to this day refuses to adress it - so it can only be adjusted by the developer/publisher. The core of the problem is Multi-Variable Conversion method that Substance 3D Painter uses on Steam; this conversation uses outdated data that punishes some regions.Poland is the prime example for this issue - in case of Substance, which base price is 199.99$, the Polish people have to pay almost 250$ for the purchase. Higher then Norway while our economies are far from comparable. Pictures below.​​So for no reason we pay 24% extra for software on steam.https://polishourprices.pl/ describe the problem the best. Best case scenario would be to match the base price (199.99$). Thanks for understanding and any help regarding this issue! 

I was unable to bake my carvature in v12. It turned out black. Same model baked well in v11.

When importing compatible ABC files into Substance Painter, mesh names for geometry masks come in with incorrect extra leading forward slashes. For example, with an ABC hierarchy of…foobarbaz...the mesh names come into Substance Painter like so:/foo/bar/baz While this could be considered just an inconvenience, it causes a practical issue.  The same source exported as FBX does not result in this same extra leading forward slash; and so if a project is set up to use mesh names for geometry masks and the model is updated between ABC and FBX, then the geometry masks will not be preserved after the model update.This can be worked-around by restricting a file to only use the model format it started with; but this seems to be a limiting restriction.

12.1.1 build 5594，The emission channel is ineffective in OpenPBR material mode, whereas it works when switching back to the previous material.

OS: Windows 11 GPU: NVIDIA GeForce GT 1030 (2 GB) CPU: Intel i5-10400F Works: Substance Painter 11.0 Broken: 11.1+ (and upwards) Symptoms: New and existing projects affected. Model initially appears white until a layer is toggled. Toggling a layer makes textures sharp. As soon as the camera rotates/pans/zooms, textures become permanently blurry. Texture Set resolution remains at the selected resolution (does not change). GPU usage stays around 20%. Already tried: Clean reinstall. Updated NVIDIA drivers. Verified Painter is using the GT 1030. Vulkan diagnostic tools run without errors. Problem only appears in versions using the Vulkan renderer. I don’t think it is my graphic’s card at fault since i even tried small texture sizes and light models and it still becomes extremely blurred (it’s not being overwhelmed), what do you guys think? Please help. 

I’m trying to bake a single UDIM as I want to adjust the cage size for that specific part. I untick all the other UDIMs. Though when I press bake I get an instant crash report. It seems to only work if all UDIMs are selected.I also have GPU and Raytracing unchecked. It’s frustrating as this is forcing me to use Marmoset for my baking.

updated my drivers to the latest and tested it in two different computers. the maxfrontal distance cage preview does not update in realtime when dragging the slider. you have to hover over the viewport before it updates

Basically the title, I was painting along, happy as can be until suddenly the lag attacked. It takes anywhere form 3-20 minutes to compute a single stroke of the paintbrush.I've uninstalled and reinstalled on my fast SSD.I've updated my windows preferences to both Best Performance on Power Settings and Best Performance on Substance Painter specifically.I have "Saved and Reduced File Size"I have upped my cache limit to the max and also moved all caches, preview, and temp files to my SSD.I have tried only working on one layer at a time.I have reduced the resolution of my UVs to 1k for the main body texture and 512 and 256 for the eyes. I have Sparse Vrtual Texture enabled/Hardware support acceleration. I don't feel like my model is particularly super detailed or layered compared to other Subtance projects I see. Processor: AMD Ryzen 5 2600 Six-Core ~3.4GhzMemory: 64GM DDR4DirectX 12 When running performance tests while it was trying to compute a brush stroke it was using 6

This started happening randomly yesterday on projects i had just worked on. Everything else works but it just crashes after reimport, when seeing the log it shows that it was imported succesfully then it crashes. The log shows no useful info about the crash. If i import the mesh again and again with the same material it works but if i reimport the mesh with another material it crashes. This happens on every project.

After updating Substance Painter from version 12.0.3 to 12.1.0, all anchor points connected to material channels no longer return the correct anchor mask. Instead, they produce a completely black mask, even though the anchor levels indicate that the values are within the expected range and are not actually black.This issue did not occur in version 12.0.3 and appears to have been introduced with the update to 12.1.0.Expected anchor mask:Expected anchorReturned anchor in material color channel:Returned anchorAnchor values in material color channel:Anchor valuesAnchor values in mask:Anchor values 

8K export re-evaluates live generator-driven height incorrectly, contaminating exported normal maps. 4K export is clean, painted height is clean, and rasterizing the generator at 4K before exporting 8K produces clean normal maps.

Use AMD Driver 26.6.1 on a 9070XTHave GPU raytracing enabledCreate new project with a low poly meshHead to the Bake Section and select the high poly meshSet output size to 4096 or higher (though even 1024 seems affected)Hit Bake Selected TexturesThen the application will go through each map without baking anything, proceeding to an AMD popup stating Driver Timeout.I have uninstalled and reinstalled Painter, removing preferences. Changed Registrys as recommended to 60 seconds, as well as tried tuning my GPU to have the lowest Max Frequency it can. All these don’t fix the issue.The only thing that fixes it is disabling GPU Raytracing, which defeats the point considering Painter V11.1 added Vulkan which should allow AMD cards to use raytracing to speed up baking. Without it something that would take 5 minutes takes roughly an hour for 7 mesh maps. 

 I’m using Substance 3D painter (Steam Edition) that i bought just 2 days ago.My baked ID texture is based on mesh’s vertex color. As you can see, the baked ID texture have the correct color like what in the 3D modeller software (Blender, 2nd image). But unfortunately, what appears in substance 3d painter viewport is the model having the incorrect color, it’s like having some sort of weird gradient, what worse is this weird color also affect the final material mode. I’m unable to pick color in masking as it’s always show the different color.5 Months ago, i’m using Substance 3D painter (Steam Edition) using subscription, i’m not facing any trouble. I’m only facing this issue just 2 days ago when i bought it, this issue also appears when i open my older substance 3D project, using this recent Substance 3D Painter.

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.
