Feature Request - Python API - Recent Files FunctionalityOpen for Voting

The Python API has always had the ability to load and save files, but no way to read write or use the Recent files.  Unless it is undocumented or somewhere else besides the substance_painter.project module. For now, someone needs to create their own UI or Recent File list if a pipeline tool is created for saving projects. Pythin API Function Request:- Ability to read the list of Recent Files.- Ability to add to or edit the list of Recent Files.- Saving or Loading either adds to the Recent Files,  or that the open/save/save_as functions offer a save to recents flag/option.This would make wrangling projects so much easier.Thanks again for the fantastic integration

More control, less friction in texturing workflows: The latest Substance 3D innovationsNews

Paul GrestyCommunity Manager

Hey there, one and all! We’re psyched to announce the release of Substance 3D Painter 12.0. This update introduces several new features designed to improve projection workflows, streamline project setup, and give artists more control when refining the final look of their assets. Some highlights include Warp to Geometry, a new projection tool developed with Adobe Research that helps project details cleanly onto complex surfaces, and a new post-processing stack that allows you to refine renders directly inside Painter. The update also brings improvements to the New Project window, automatic UV generation for hard-surface assets, and more. Take a look at the full announcement in our post on the Adobe blog, which you can find at the link below. You can also find news about updates to Substance 3D Designer and new content in the Substance 3D Assets library. We hope you enjoy the update! Keep creating awesome stuff!

Error Accessing Embedded Presets - Python API

Hello guys 🙂 I’m hitting this error in my Substance Painter Python exporter: ValueError: For exportList item #0, the preset "resource://starter_assets/glTF PBR Metal Roughness" is undefined I am using Everything (voidtools) to try and locate it, but I can’t find that preset on disk anywhere, I am assuming it is embedded. Do you guys know where it's coming from? Any other preset from the starter-assets folder work fine. How can I access the glTF ones?  Any help would be appreciated, thanks 🙂

Can't find where glTF Metal Roughness export preset lies

Hi there! I have faced an issue with locating glTF PBR Metal Roughness export preset. I want to write plugin using it so it would be helpful to know the ResourceID of this preset. Any piece of advice will be helpful. Thanks!

Multiple Export Parameter Templates with Separate Output DirectoriesOpen for Voting

When iterating textures, it becomes time-consuming to repeatedly export each texture set into its own directory. Currently, exports are limited to a single output directory per export, which means I need to re-export each texture set separately into its respective folder. This becomes a time sink for any project with multiple texture sets.It would significantly improve workflow efficiency if we could create multiple “General Export Parameters” templates, each with: its own output directory an assigned texture set After setting these up once, re-exporting could be done with a single click while automatically routing each texture set to its correct folder.This would streamline iteration-heavy pipelines where textures are frequently re-exported.If there are technical or compatibility reasons this hasn’t been implemented, I’d also appreciate insight or recommended alternatives.Thanks!

绘画笔刷右边的一直显示无材质

In Substance 3D Painter, when painting on the mask of a fill layer, the brush always displays "No Material". This happens with all brushes, and restarting the software doesn’t fix it. What’s the problem? This didn’t occur in older versions; it only started happening after I updated to the latest version 11.1.2.

Version 11.1.3 Generating Thumbnails consistently which slows down Substance Painter to a crawl.

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

Jagged edges on the model after baking

Hi everyone!I created a simple, slightly conical circular band model in Blender (image 1). After UV unwrapping (image 2), I then exported the high- and low-poly models in FBX format.In Substance Painter, after baking, I get noticeable jagged edges on the model (image 3).For baking, I set the antialiasing to Supersampling 16x, and the output size on 4096x4096.After baking, there are jagged edges (image 3).Why does this happen and how can I fix them?Thanks so much!123

My autosaved project won't open, giving "Failed to Open Project" and I lost my original project file, v 11.1.3

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!😫

AMD GPU baking issue

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).

Add the option to choose which specific installation of After Effects 'Send to AE' uses.Open for Voting

Hi, hope you’re good 👍🏾I’d like to request an option to point at a specific After Effects installation for the Export > Send to After Effects command.Use case is that I have a bunch of different versions installed for older project/plugin compatibility reasons, plus I’m working in the AE Beta for testing most of the time. The current functionality seems to automatically send to the most recent release version, and it would be a big timesaver to be able to specify which version of AE to send to, especially as this command can generate just and GLB file without all the maps as well.I’d imagine the most straightforward place to put this would be in the config options for Send to AE - there could be a dropdown with all the recognised installations, and a checkbox to enable selecting a version manually.With all the good work that the AE team are doing with substance and 3D integration right now, having this flexibility would offer quite a big quality of life upgrade.Cheers!

Need ability to export UDIM tile's name for game engineReleased

The UDIM numbers are not useful for game engines, yet they are essential for painting and baking across multiple parts of the mesh in Substance Painter.   Instead of having to look up what part 1004 is, it would be nice if I could export it with the name I put on the tile within Substance Painter.

Critical error can't build edition context. Invalid edition target.

Hi all, I am getting the following error over the last couple of weeks and I have no idea what the issue is. “Critical error can't build edition context. Invalid edition target”This pops up on different models and models that have worked with no issues before. I have updated to the latest edition but it hasn’t fixed the issue. The error pops up randomly when I am working on a model and I can pin point it to anything one thing that I am doing. Any help would be amazing as this is preventing me from completing work.

Mac trackpad navigation does not work correctly inside Painter

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.
