Substance 3D Painter

As I was working on my character model, the default material sphere disappeared when I creating a black mask. I used the “Smudge” tool a few layers back to smooth out the redness of the lips. However, once I got out of it, it caused the default material sphere to disappear whenever I create a new fill under a black mask. Because of this, if I use the “Dirt” brushes as an alpha, it would have a squared border. However, if I choose one of the “Dirt” brushes from my Asset Library, it would appear normally without the squared border. To get back to the “No Material” issue, even if I use the “Paint” tool as some suggested to fix the issue, it will still immediately disappear when I choose a different option. If I reopen Substance Painter, everything will appear normally until I click on a different tool, which causes the grey sphere to disappear. I received this red error message in my log stating the following: [GenericMaterial] Shader API has been updated. Textures may briefly flash white

Is there a way to prevent polyfill from filling random polygons on surfaces hidden from the camera by the surface I intend to paint on? If not, I'm afraid I won't be able to contain my increasingly violent intentions towards the Substance painter dev team. 

I want to set the Output Folder of File/Export Textures gui, via python API.Is there a way to do that, if yes how? Also the same question for Output templateIs there a way to set (select a template) it via python, if yes how? Also the same question for New Project/Project template.Is there a way to set (select a template) it via python, if yes how?   Thank You!

Hi,I’m getting strange black/white noise or dots in the Substance 3D Painter viewport, as shown in the screenshot. The same project looks normal on another computer.Could this be related to the GPU, driver, or viewport settings? What should I check or compare between the two computers?Painter version: Substance 3D Painter, version 12.1.3Build 5709GPU: AMD Radeon RX 5700 XTOS: Windows 11 Version 25H2

Anyone know why this is happening, for some reason some uv island in a single mesh isnt getting mask when i try to mask the whole object but when i try masking comletely unrelated object that part is getting masked. i checked the uv, it isnt overlapping or anything and there is proper padding too. watch the video to clearly understand the issue 

I'm waiting to purchase the Substance Painter Steam version of 2025. It'll be the end of January and still nowhere to be found. I don't want to buy the 2024 version which will no longer be updated. Will there be any discount for the 2025 version if there will be only 11 months or less of support instead of a year or will the update period cover 12 months from the release date?

Hello,I purchased Substance 3D Painter 2026 on Steam on August 27, 2026, and I am using version 12.1.3 on Windows.During actual production work, I have experienced frequent random crashes, errors, and unstable behavior. I tried restarting the application, changing settings, and repeating work after crashes, but the instability has made it difficult to use reliably for professional production.I found Adobe’s official announcement published on August 28 regarding random crashes in Substance 3D Painter 12.1.3 on Windows:https://community.adobe.com/announcements-57/12-1-3-random-crashes-1639216Could you please confirm whether the random crashes I am experiencing may be related to this known issue in version 12.1.3?I purchased the software specifically for professional production work, but because of the frequent instability, I am currently unable to use it reliably.I submitted a refund request to Steam, but it was declined because my usage time exceeded the standard two-hour refund limit.

Hi, Is there a way to prevent a PassThrough filter/Layer above from reading through a specific folder?For example, a folder blend mode that would act as a boundary and prevent filters above it from detecting the layers insidethat folder?Is this possible in Substance 3D Painter?

Although I heard that ID map isn't strictly necessary, I still baked it with submesh as a color source. Also all meshes were knife cut and separated in blender either way. But when I click on for example an engine part, for some reason it also selects a part of the wing. In another example I click only on the right elevator and it selects almost the entire mesh. What am I doing wrong?  

Hi thereAs you can see in image below, my curvature mask is being display with horizontal and diagonal direction, why? I want to add a darker shapes only on areas where the normals are pointing down ( is a palm tree ) ( i am a noob just starting with Painter ) Help Thanks 

Hola. Intentaré ser breve :)Equipo con 32GB de RAM y NVIDIA RTX 4070 con 16GB.He modelado en 3D MAX 2026 exportado como FBX2020.He abierto el modelo en Blender para esculpir las texturas y exportado como FBX.He abierto el modelo en Substance 3D Painter para exportar los Heightmaps y aquí es donde tengo el problema, me pasa lo siguiente:Substance genera la carpeta temporal correcta pero en un momento dado la borra, incluso con el contenido que ya hubiera podido crear en ella y me devuelve este error:"[Library] Error al exportar el recurso 'height OgreTeeth': Error al guardar."Después de muchas pruebas usando tanto Exportar texturas como Exportar recurso y habiendo borrado los directorios de cache:C:\usuarios\MiUsuario\AppData\Local\Tmp y C:\Users\manel\AppData\Local\Adobe\CacheMe sigue dando los siguientes errores:can't be generated" para las 4 UDIMs (Height, Height_1, Height_2 y Height_3).El orneado lo hace bien, el problema está cuando hago el export de los Heightmaps¿Alguna sugerenci

I’m painting manually base colour and normal material for my model. After a while i turn the model to check the other side and I’m met with this huge black spot. I go through single channels, it is only shown in normal channel and normal+height+mesh channels. I tried to delete it by using eraser with normal material only turned on, nothing happend, it only deleted the actuall normal materials under it. I cant paint over it or do anything to it. One bad thing that I did is that I painted base colour and normals in one layer. So I can’t really delete just one layer that could have had the normals painter in it.
