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 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]

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?

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.

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

So im currently at my job atm and Im bringing in a model to bake in substance basically to bake the maps from a HP onto a LP, and when it bakes it bakes everything but when you try to use the bit map as a mask it just said fails to decode map. This has been an issue for i dont know about a year or more i feel and ive seen multiple threads about this but zero answers now myself and alot of other customers have had this issue and were paying customers can somone please for the love of god figure out what is going on within substance painter. [EngineBitmapLoad] Failed to decode bitmap.resource://project2/Curvature Map from Mesh body?version=a7b603ca8fc7757fb5c46344211c1902f42c323f.image error code Im not bring ANNNYYY textures in this is just what i think you guys have programmed into the actual texturing software and somthing is bugging up the system this WAS not an issue before adobe took over but alas here we are dealing with zero help and no solutions im sorry for

Helllo!I've created a custom material, importing it into painter and using it as a custom brush (a nuts and bolts generator) but I'm getting some major aliasing / bit depth artifacts in Painter where in Designer it looks fine. I've done various testing but cannot get rid of this artifacting at all. Does anyone know the issue here?Thank you,Marcus  

hy guys so i'm working on texturing a model of my own but i can't find the solution to this problem :when i bake my model, i obtain this , which is quite cool but when i look at my normals, i get this, which is a big problem  i tried a few things, flipped my UVs, but i really am out of options based on my limited knowledge of the soft If a life saver can answer me, he'd have my eternal gratitude thank you

Hello there!I am currently experiencing some trouble while developing a python plugin for the newest Substance Painter version (8.1.2).Lets say I want to save some string data from my plugin to the project file, when the project file is saved.My current approach is to write that into the projects metadata, when the project is about to be saved, using the substance_painter.project and substance_painter.events module.Consider the following pseudocode: import substance_painter.events import susbtance_painter.project class PseudoClass: def __init__(self): ... self.event_dispatcher = substance_painter.events.DISPATCHER self.event_dispatcher.connect(substance_painter.events.ProjectAboutToSave, self.save_settings) ... def save_settings(self, event): metadata = substance_painter.project.Metadata("PluginSaveData") metadata.set("plugin_save_data", "testsavedata") This should work in theory, but sadly raises the following Error instead:[Python]

Hi!I have been working on a character and baked my high poly onto the low poly in substance painter. Hoewever, I keep getting some weird results on the neck. I have tried a bunch of different things already but to no avail. There are no visible issues with the low or high poly, and there is no overlap in the UV's, yet I keep getting this one error in the middle of the neck as well as these subtle lines (looks like stretching to me) on the sides. Below you will find images of my bake, the wireframe, high poly (decimated) and UV's.  (I am using UDIMs for the UV's)          

Im doing a script to process a list of .spp files, and at end of my script Im using substance_painter.project.close() to close the current file and repeat the process with the next file in the list but this command closes the Substance Painter instance and not the current file. There is another way to process a bunch of files? A strech of my script is:for i in range (100😞 substance_painter.project.open(substance_painter_projects[i]) #do something substance_painter.project.close() #jump to the next file 

Hello, i'm currently trying to export my textures in 8k from substance painter. The problem is that squares appear in my textures and only when i'm exporting in 8k. If if I export in 4k, the problem doesn't happen. I join a screen of the texture in 8k with the square problem, and a texture in 4k without the problem.As I really need to export in 8k, could you help me to find a solution ? Thanks  

Is there a way to work with material references between files?For example, I have a wood material in a file, and I would like to reuse it in another one, but if I change the source file of the wood the other files will be updated.Something similar in Blender we have the "Mark as Asset".

Hello,can someone point me in the right direction?The mesh was auto UV unwrapped in Substance, and Im trying to paint in the eye shadow. But the paint stroke is super blurry in some parts and sharp in other parts. I've illustrated the issue by painting a diagonal line across the face. You can see the line is varying thickness across different parts of the model.How can I get the paintbrush strokes to remain constant across the entire model??
