Substance 3D Painter

Hello,I'm writing a Python plugin for Substance Painter and I discover a bug that creates crash on startup:I have a virtualenv containing these versions:PySide2==5.12.5Qt.py==1.3.3shiboken2==5.12.5 I add virtualenv's site-packages to my PYTHONPATH and launch Painter with this script inside startup folder : from Qt import QtWidgets import substance_painter PLUGIN_WIDGETS = [] def display_dialog(): main_window = substance_painter.ui.get_main_window() dialog = QtWidgets.QDialog(main_window) dialog.show() def start_plugin(): global PLUGIN_WIDGETS menu = QtWidgets.QMenu("&Test Menu") action = unit_menu.addAction("Test") action.triggered.connect(display_dialog) substance_painter.ui.add_menu(menu) PLUGIN_WIDGETS.append(menu) def close_plugin(): global PLUGIN_WIDGETS for widget in PLUGIN_WIDGETS: substance_painter.ui.delete_ui_element(widget) PLUGIN_WIDGETS = [] I just add a menu "Test" with a "test" action insi

I have recently purchased Substance Painter 2024 perpetual on Steam , i imagined i would be getting a year of updates like any regular software you buy, but now i see Substance Painter 2025 has released on Steam and my version is still 2024.This should not be the way this works , if you get a year of updates , this should include a free upgrade to the newer version. If you purchased 2024 the day before 2025 dropped this would litterally feel like a scam. Is there a way to upgrade SP 2024 to SP 2025 without having to purchase it again after 3 months ? 

It is exactly as it says. I am trying to load my material shelf, and it will only load the materials that start with a number to the ones that start with the letter F. Others will not load, and it is extremely frustrating. I do not know what is wrong. The program also will not close properly; I have to go to ask the manager to close the program, which I have never had to do before, but its freezing my PC a lot. Can someone help me figure out why Substance Painter broke and how I can get my library to load? It constantly is saying generating thumbnails, but nothing; I have uninstalled and reinstalled everything. I have my local cache at 3000, and my Specs are a 3900x and an RTX 4090, running substance from an SSD 

I only see export mesh and export texture.  

I was using Substance Painter the other day, everything was working fine. Then I opened a file and it shows a white screen and it doesn't respond. This happens with every file, and I restarted my computer thinking it would help (it didn't). I saw that other people had this problem as well. I don't think I have the most up to date version of substance (6.2.2) but I am afraid to update it when it isn't working. Attached is what I see when opening a substance file, and a pic of my specs. I believe my driver is up to date as well. Thanks.

In the old substance painter at default, there should be a grayscale slider in the grayscale tab when doing the paint mode which is now missing on my painter 3D. Am I missing something here is is this a bug?  

Hi all,I have a clean install of the latest version of Painter.All I did was set the color management to OpenColorIO and import a mesh with baked maps.I then applied a fill layer and used a hex code to set a specific color.As you can see in the image, the colors don’t match.The hex code from the website, which should be correct as far as I know, appears significantly different in Painter—both in the Fill Properties and on the mesh itself.Ignore the second fill layer, it has no effect in this example.So, why is this happening? What could be causing this behavior, and how do I fix it?

Hi guys.When I import my 3d model in Substance 3d painter and bake it, Apparently there is a problem with ambient occlusion.How can i Fix that?model in blender and unwrapping in rizomuv, and bake setting was default.

Thanks for clarifying! I would like to know if the steam version of substance painter has any downsides compared to the normal one, and if it is just a 1 time payment of $200? [Message moved and edited by moderator]

Hello,I am using version 10.1.2 and Windows 11.When I try to export my textures it doesn't work, in the log says "[Library agent] Failed to save updated preset 'Arnold UDIM Legacy (AiStandard)': The default library 'starter_assets_1' is only available in read mode because you don't have write permission on it.". I want to export my textures in Arnold UDIM Legacy (AiStandard), exr 16 bits. If someone can help me please, thank you.

As seen on picture, when I use some smart mask or smart materials which contain Mask Editor, they appear as squares. I bake maps in Marmoset and then import in substance painter and texture it. What could be problem?

Hi, I have a strange issue with the new version ( 8.3 ) of Substance painter. When I am going to render view and try to render an image, it is rendering until I touch something. Even clicking on the blank space between buttons resets render. Iterations reset to 1, and the image is blurry. It won’t be such a deal, but pressing ,, save render” button causes same result - render resets and i cant save renders with more than one iteration. Few things i noticed: it works like that for every project; when I moved back to 8.2, problem disappeared ( i have the project in 8.3 version so i can’t edit it there ); Iray resets render even when i am changing windows on my computer. Also tried to reinstal Substance few times, nothing helped. I am working on m1 Mac with Ventura 13.01. Does anyone know how to solve it? Thanks in advance

My Fill Color Picker in Substance Painter starts lagging badly after a few minutes of use. I’ve already tried running the app as Administrator and even reinstalling it, but the issue persists. The lag makes it difficult to change colors smoothly. Any suggestions on how to fix this? My pc: AMD Ryzen 7 5800X3D 48 GB RAMRTX 3090 Video showing the issue: 

i baked some details on a flat plane for a trim sheet. and i got this issue a couple times (see Picture) i tried a lot to get rid of it but i cant seem to find the problem, does anyone have an idea how i can go about this?  Also its this way in every map not just the normal.   

Hello I am new to substance painter and I am trying to figure out how to stop the normals of one material that are bleeding through to the other. I have had added a screenshot that hopefully helps show what I am trying to stop.

Hello, I've been trying from a couple of day to open my Fbx files on Substance painter for my college assignments but I'm not able to. I've heard somewhere to try Obj files but Obj files are not opening as well.I've also tried cleaning up the file in maya and also reinstalling substance painter but it's still not working. Please help!I've attached the screen recording below while trying to open the file, I'm getting the left bottom corner errors.

I've been using Substance Painter for about three years already using student access provided by Adobe, which is also mentioned clearly here https://substance3d.adobe.com/education/ Recently, my licence ended, so I did request another for third or fourth time like I did before. This time they provided me link to verify my student status, which is not working. (The link https://www.identit-e.com/adobe ). As I need it for my studies, I contacted Adobe through chat, asking to grant me my student access as I am a student of higher institution. In return, I was told that "they don't have student plans for Substance". Which is a lie (?) because the website still mentions that Substance apps are free for students and teachers. For every question I had, I was told to refer to my university. But my univeristy does not provide licenses and it has always been done by students using this link https://substance3d.adobe.com/education/ .At the end, I was told that they d

I'm having a problem with making panel lines in Painter. I can't get the line to go all the way across half the time, even when I go well beyond the edges. Is there a way to prevent this?

I am a freelancer from Russia planning to work for a European company as a short term contractor. In Russian Steam, there's Substance 3D Painter 2025 in two versions: perpetual and subscription. My question is - which version do I need to be able to sell my textures and .spp files to the companies so they can use/modify my files in their commercial projects? They told me they have Adobe subscription for studios, and they are concerned about the "2. Restrictions" of the license agreement. Please clarify which Steam version I can use, if any?

Hi! There is a problem in Substance Painter. I am exporting a model from Blender to Substance Painter, and white lines appear on the borders of the UV islands when sharpen is turned on. The same problem with bevel. I checked the curve map, it baked correctly.I’ve been experimenting with different padding sizes – I was previously using 0.002 (which is what I always used when texturing in Blender), but have also tried going up to 0.01. Unfortunately, none of those changes seemed to make any difference in how these artifacts look.I have a hunch why this might be happening. Typically, sharpness filters in different software look at neighboring pixels to determine the color of a specific pixel. Since there are no pixels outside of the UV islands, the sharpness filter seems to be using a pre-defined color – which is clearly not matching the texture’s actual color. I think expanding the texture beyond the UV islands could help with this, but I’m not sure if Substance Painter has that function

Issue:I receive 3D model files from my team, who work in KeyShot, and when I import them into Adobe Substance Painter, the model appears disassembled or not fully put together. The same files seem to work fine in KeyShot and other software like KeyShot Viewer.Details:The files are exported from KeyShot in FBX, OBJ FilesWhen opened in Substance Painter, the parts seem to be separated or misaligned.I've checked the files ingestaltor.io & KeyShot and they appear fine there.My primary goal is to apply materials and colors for a color study rather than detailed texturing.Why I’m Using Adobe Substance Painter:I’ve been using Adobe Dimension and love how easy it is to apply materials and render scenes. However, I’m looking to step up to a more advanced 3D workflow. Is Substance Painter the best tool for this kind of work, or would another Adobe or third-party tool be better suited for color/material studies?Troubleshooting Steps I've Tried:✅ Opened the file in another 3D viewer to v
