Substance 3D Painter

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  

I am making a project for a helibase to be used within msfs2020/2024. The model is painted in SubstancePainter and I am using different layers. I start by baking the model (a building) using document resolution and output size to 4k. I am baking the world space normal, AO, curvature, position, thickness and bent normals. I am not including the opacity, height, ID and normal in the baking process. After baking is complete I paint my texture sets, and I adjust the texture set size to a maximum of 2k, but also down to 125x125, depending on it’s visibility on the building. I use multiple layers on faces such as walls and roof. When the model is finished I export it as a .gltf file for final adjustments within Blender.  My issue is that when the project is complete and built within msfs2020 development mode, the texture files are very large in size and I need to reduce them.Is there something with my workflow above that I could do differently to reduce the texture size even more? Is there s

I want to programmatically set the Output Template before export. So that when someone goes to export it is already prefilled. I am making a tool that opens Painter and does project set up and initial baking. It shouldn’t export anything, however I want to set which export preset should be used. Is there a way to set Output Template from Python (or JavaScript)?  

Hi, I just installed Substance Painter and it won’t open from Creative Cloud. For context, I have PS, zbrush, blender, maya, etc and they all work fine. PS opens fine from Creative Cloud. Substance is the only application that simply does not open. When I click on it from CC, the mouse gets that little buffering icon for a second and then it disappears. No error message or anything pops up. I also tried going to the .exe and running as administrator. An error pops up and says “The application was unable to start correctly (0xc0000142).” I have tried a fresh install but no luck. I am running windows 11 and have an nvidia geforce rtx 4060 GPU with updated drivers. All other 3D software works fine.

Hello,I am looking for a feature in Substance 3D Painter that functions exactly like Blender's "Paint Mask (Face Selection Masking)".In Blender, I can select specific polygons and use a BRUSH to paint within those boundaries without the paint bleeding onto unselected faces (see attached Blender screenshot).  In Substance Painter, I cannot find a direct way to do this. The Geometry Mask only allows "Mesh names" selection, and the Polygon Fill tool only fills faces with solid colors rather than acting as a brush boundary.Is there a direct way to use polygon selection as a "live boundary" for the brush tool in a standard workflow?I want to confirm if this fundamental feature from Blender is simply missing in the standard Painter workflow or if I am overlooking a specific setting.Thank you.

I’ve been having an issue when baking my low poly mesh with my high poly mesh. I’m fairly certain its due to the software reading one part of the mesh as another, but i have no idea on how to resolve itImage described​​​​Issue shown while baking 

I added the roughness channel from this turtle skin material, on top of a aluminum material to add a pattern. It creates these outlines with spots in the center. How could I make it so the outlines in the metal have a different color? Could I also make a separate color for the grayish spot in the centers?

Hi everyone,I'm new to SP and am trying to understand how texture placement works with the various Projection options.In Image 1:you can see how I assigned the different projection modes for each side of the model. And from a relatively far away, it doesn't look bad.But up close, in Image 2:the UV stitching lines are clearly visible.How can I fix this?Thanks! 

I have a problem where I put my texture into roblox studio so it can add it into my mesh but for some reason it gives me errors. Does anyone know how to fix it? plz help

I recently updated to Substance painter 12.0 today, updating one of my projects I was working on.I then go to export the textures to files, same as I’ve done for years on previous versions and..it does nothing. Just sits there, no files generated, just stuck on computing textures results.Have tried reinstalling, no change. Was working fine on the last version.

Substance Painter 12.0.1 I have this issue where after baking all the maps look fine except world space normal (see first screenshot). The mesh is triangulated in Blender before export. And I have re-imported the FBX to blender to triple check this. Must be some baking bug in painter? Not having a correct world space normal is really messing up all the smart materials, not sure how to fix it. World Space Normals in Painter Blender MatCapAttached my exported FBX if you want to test it.

Hi guys, I'm having an error when baking any model in the software. It creates artifacts on the AO map that are the same in all models. I tried to find a solution for this, but I was unsuccessful. Could somebody help me?  

Hello yall,So I recently began a 3D model journey in which I would texture using photoshop. I decided to pay for Substance Painter on Steam to use a better program. [according to other creators]. However I have recently run into a issue.Any time I try to export a texture file the program will crash. Sometimes I can export a texture or two before it decides to crash. I am exporting what I consider a basic texture, 2D View png 8 bits 2048 and Dilation + transparent, I tried to make it 1024 and still crashes.My computer is not buns at least I don't think so, my specs are a Ryzen 9 5900x amd gpu 7900xtx and 64 gb of ram. I have 3tb of free space on the drive where substance is installed. If anyone knows a fix or a way to trouble shoot please let me know. It has stopped my work flow. 😓I watch my PC usage and nothing seems to spike while exporting. This just started recently and I even rolled back but nothing changes if anything it got worse

I recently purchased the newly released Substance Painter 2026 on Steam. As the latest version, I expected it to support available downloadable resources.However, I noticed that a free resource pack (materials/assets) on Steam requires Substance Painter 2025 to be installed in order to use it.This raises a couple of questions:Is there a specific reason why this pack is not compatible with the 2026 version?Are there any plans to update it for 2026 or release an equivalent pack for the new version?It seems counterintuitive that the latest version cannot access content available to a previous one, so I’d appreciate any clarification on whether this is intentional or just not updated yet.

Since the last update, everytime i export a model directly to subtance stager to take photos, the model doesnt export the roughness channel, you can see in the first photo how the model dont have any roughnes map, looks like plasticine, the second one has the same materials and the rouighness look way different, works perfectle and was exported with older version, this ruin all my workflow since the update, someone else has the same problem?? 

The 3D mesh file is in obj format. After drawing with a pen or brush, when sending it to Stager for display, it shows that the model cannot be imported. However, if you go to the project configuration, change the import settings, remove the retention of the brush positions on the mesh, and re-import the mesh, it can be imported normally again. The cost is that it will change the position of my pen path. Is this a bug?

Spoiler: Curve Shape slider does nothing related to sharpening a curve marked red on a screenshot.
