Substance 3D Painter

Should i mark Sharp edges on my low poly(Shade auto-smooth) or shade smooth for high poly to low poly baking?I did an experiment of baking into the low poly once with sharp edges and another without.1st image is with sharp edges marked.2nd image is without any sharp edges marked and shaded smooth.*No custom normals.**High poly(subd) ofc is fully shaded smooth.***Working in Blender.

When I open substance painter, it doesn’t matter what I do, after around 3 minutes, it will just close. It does not crash, as if I’m in a project, it will ask to save before closing. It was working perfectly fine a couple of hours ago. Please help me with this! I really doubt its GPU related as the program is not crashing, it literally just closes. I can just be on the home screen and it will still close.

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. 

Can’t change light source direction (shift+right click) or slide any of the control sliders. Makes the painter process extremely painful.

Hi, I cannot really know why I do not have materials showed in the right side of the bar, I have tried multiple times for finding solutions but no much usable information found.  

Sub Surface Scattering isn’t rendering properly for me. I have tried almost everything from changing the shader to remaking the entire model Weirdly brightens up the model when I turn on SSSRenders fine without SSS. As you can see, it weirdly brightens up the model. It’s renders fine without SSS. I just can’t figure out how to render out the SSS. I have baked a thickness map and inverted that map for the SSS and it should render out without any problems. Any Help will Really be appreciated.

When I try to launch substance painter on steam it does not launch.I have the Substance 3D Painter 11.1.3 currently.I paid a lot for this application to never be able to use it, as you can see by my 45 minutes of usetime spent to try to open the application. When I press play, substance sends me to the lauchscreen, and then it collapses and I can press play again. I need this program right now, any help is welcome!I have tried:updating pc and graphic cards clean reinstall How can i even contact support? There is no where to contact anyone :(( So i am trying here… (and no, my program is too old for a refund, as that is  2 weeks, but I don’t have a functioning program so...) PC specs:Processor: AMD Ryzen 9 5900HX with Radeon Graphics (3.30 GHz) Installed RAM: 32 GB Graphics card: NVIDIA GeForce RTX 3080 Laptop GPU (8 GB) AMD Radeon(TM) Graphics (497 MB) System type:: 64-bit operating system, x64-based processor  

I’m having an issue where the Steam version of Substance Painter won’t launch.

Hi, Substance Painter crashed and now I cannot open my project file. It gives me the "Failed to open projectsettings.ini" error and exits. I spent too many hours on this mapping work and I cannot redo this from scratch. Could you please check and fix my corrupted .spp file? Thank you.*This post has been moved by a moderator.

I read all threads and I’ve seen this an ongoing issue. Baking and artifacts on edges, where the Normals are bending over 90 degrees.Regardless, even when not using sharp edges, and having a clean seam underneath, the unwanted ‘warping’ effect around the edges is clearly visible, especially when using a pure high glossy metallic reflection material like pure chrome. I think I pulled very trick from the register, to avoid these lousy looking artifacts, but no success.I wonder, perhaps there is anything substantial I’ve been totally missing here?Thanks for any little help,appreciate it! 

Run painter in cli with --help, --enable-remote-scripting is missing.Run with --help-all does nothing like what it claims to be doing.Documentation https://helpx.adobe.com/substance-3d-painter-python/api.html does not contain any mention of remote scripting.It is only found on https://experienceleague.adobe.com/en/docs/substance-3d-painter/using/scripting-and-development/scripts-and-plugins/remote-control-with-scriptingAnother bug, but that is related to this site. Editing the “Describe your bug” essentially creates a new one so anything users have written about a bug is deleted. 

I’m creating a new post about this topic because everywhere I see theres no solution. I can open the file, and I can export texture, but I’m not allowed to modify it since if I do anything it starts to load and never finish, ending up to be closed by ctrl alt del. I’ve seen in way too many posts, for some years ans this bug is still nowadays all strong. Whats the problem with this software? its a industry standard going with the same bug FOR YEARS. This is just ridiculous

(Sorry my bad English, still learning...)I'm having the problem that the loading bar is stuck at about 30-40% of the way when I try to open a project, I've left it open for about 2 plus hours and the loading bar dont move at allThings i tried: reinstalled Windows 10, cleaned my PC, updated all drivers...I really don't know what to do and I'm very frustrated because I can't work. PC:Ryzen 7 5800x3d32 GB RAMRTX 3080The program simply doesn't consume RAM, cpu or disk or other resources, it just makes my GPU go to 100% I have the most current drivers for my GPUMost current version of the programProject is less than 200MB in size​Any tips or suggestions i could do?    

I have a substance 2025 perpetual license but I can't find a download link to be able to install the software on a new PC? Is it possible to download previous version of the substance suite for older perpetual licences?
