Bug Reports

Using Unreal Engine 5.5.3 on windows 11 and Substance in UE5 Plugin 5.5.1, when doing a recompile for my C++ code, the build fails related to "SubstanceCore".I have to disable the plugin to be able to build the project. ---------- Creating patch ---------- Running C:\Program Files\Epic Games\UE_5.5\Engine\Build\BatchFiles\Build.bat -Target="TestProjectCPPEditor Win64 Development -Project=""C:/Users/rhaam/Documents/Unreal Projects/TestProjectCPP/TestProjectCPP.uproject""" -LiveCoding -LiveCodingModules="C:/Program Files/Epic Games/UE_5.5/Engine/Intermediate/LiveCodingModules.json" -LiveCodingManifest="C:/Program Files/Epic Games/UE_5.5/Engine/Intermediate/LiveCoding.json" -WaitMutex -LiveCodingLimit=100 Using bundled DotNet SDK version: 8.0.300 Running UnrealBuildTool: dotnet "..\..\Engine\Binaries\DotNET\UnrealBuildTool\UnrealBuildTool.dll" -Target="TestProjectCPPEditor Win64 Development -Project=""C:/Users/rhaam/Documents/Unreal Projects/TestProjectCPP/TestProjectCPP.uproject

When opening levels in the Unreal Engine editor, the process is extremely slow. Upon investigation, it was found that the delay is caused by the RebuildAlert function, which calls Substance::Helpers::SubstancesRequireUpdate. This function iterates through all Substance assets and calls GraphRequiresUpdate on each.The issue lies within GraphRequiresUpdate, as it internally calls AssetRegistryModule.Get().SearchAllAssets(true). In Unreal Engine 5.4.4, this function introduces a 100 ms sleep. With 1000 Substance assets in the project, this results in a delay of 100 seconds when opening a level.I noticed that in all occurrences (two) of GraphRequiresUpdate being called higher up in the stack, AssetRegistryModule.Get().SearchAllAssets(true) had already been invoked. Therefore, I commented out the AssetRegistryModule.Get().SearchAllAssets(true) call within GraphRequiresUpdate, which eliminated the significant delay when opening levels.Steps to Reproduce:Use a project with a large number of S

Please someone tell me how to solve this prob ? 

Unable to load SBSAR materials into Blender. The console error log is attached.I have uninstalled and reinstalled multiple times. The addon is working in Blender 4.2, but not 4.3.

Hi Adobe Rep + Community, I can't get the Adobe Substance Plugin for Blender working. I am using the Blender v4.2.2 LTS on Windows 11 (23H2) with the latest Substance3DInBlender and Substance3DIntegrationTools, v2.1.1. I don't have the Substance Plugin installed for any other 3D package. Is there anything else I can do to troubleshoot this bug? This is the screenshot of the installation: Thank you,Toan

And this is the screenshot of System Console when I click the Load button..

The discord links used for "Feedback: Report a Bug" and "Help & Resources: Discord Server: Discord Server" are invalid.(Windows, Blender 4.3.2, Substance 3D Add-On & Integration Tool version 2.1.1)

Hi!Im on a Mac trying to install the plugin but when i try to install the integration tools it shows me this message , can you help me please?

Hi! I am attempting to use the Substance Plugin for Maya to generate my hyper-shade network for Redshift. However, whenever I try to render the scene I get the error message "(substanceOutputNode) is not supported by Redshift." I was able to get Redshift to render the scene perfectly fine once time before it returned to giving me error messages. Any help would be appreciated! 

Currently using blender 4.2 and aslo tested the pluggin on blender 4.0 but either version gives the same result, working on an HP Pavillion laptop running windows 11, the plugin is version2.1.1. The sbsar material will load in with all the correct exposed parameters but when clicking apply it always says the material must be rendered first but never does 

the fact is that when you press the "load" button, several seconds pass and instead of opening the archive selection browser, the inscription "Substance 3D in Blender: SRE Initialized successfully in [2.029] seconds" is displayed I reinstalled the addon and tools, even installed different versions of the blender, but nothing works 

Hi im new to this side of 3d. When I try to use the plug in "substance 3d for unreal engine" in UE5.3.1 and 5.2.1  to import a sbsar file it shows this error and does not show up in the folder: And when I try to import the same file a second time in a row I get an overwrite warning for the file like it was allready imported:If I click Yes, the file appears in the folder, but I cant use it, and sometimes UE crashes.Here are some logs:Im going to try on UE4 next

After loading and applying a sbsar using the Adobe Substance Blender Add-on, objects exported to gLTF or USD lose their material.  No textures are exported or embedded into the files. gLTF export works fine in current Blender 4.2, though USD export still seems to lose the material.

I tried to load a .sbsar file and received the following message in Substance 3D in Blender: "Substance file [base-concrete.sbsar] located at [D:\blender檔案\texter\base-concrete.sbsar] could not be loaded."

The load page does not appear due to an error

i am using Unity 2022.3.22. When i import the substance to unity plugin i am met with these errors.  I am targetting the Android platfrom as i am making a VR experience. I have changed the the .so files in the plugin folder to include android but this does not help . I did see others with this issue but they said they fixed this issue with the sbsario.dll file. Any help would be greatly appretiated 🙂 

I noticed that using "Substance2" node will increase rendertimes from 400%-1000% compared to old "Substance" node. This makes Substance workflow very difficult right now. I can replicate the effect just by connecting substance map in to the Diffuse slot of a material and rendering.We use V-ray 5 but the perfomance issue is noticeable with Arnold renderer also. I have contacted Substance support and have not recieved any solutions.I have switched Substance engines between GPU and CPU but no difference in render time. Also noticed that the "Substance2" resource allocation is different than the "Substance". Please see the images  and compare the render times and see the picture from the Task Manager. 

Hi im having trouble booting an older project with substance materials. Ive updated everything to UE 5.3 and installed latest plugin but when booting any project with existing materials from substance, it fails. Is there any way I can get around this?Thankshere is the crash log:LoginId:3513e7b349de3ff6ba70b1876b562d95EpicAccountId:b2218432cad24958b00a013ed0dd3db8Assertion failed: [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\LinkerLoad.cpp] [Line: 4616] Z:\HYPERDRIVE\UNREAL_ENGINE\Projects\Megascans 4.25\Content\Materials\Substance\3D_Printed_Triangle_Links_INST_ambientocclusion.uasset: SubstanceTexture2D /Game/Materials/Substance/3D_Printed_Triangle_Links_INST_ambientocclusion.3D_Printed_Triangle_Links_INST_ambientocclusion: Serial size mismatch: Got 312, Expected 600KERNELBASEUnrealEditor_CoreUnrealEditor_CoreUnrealEditor_CoreUnrealEditor_CoreUnrealEditor_CoreUnrealEditor_CoreUObjectUnrealEditor_CoreUObjectUnrealEditor_CoreUObjectUnrealEditor_CoreUObject

I made in Sampler an SBSAR with the Embroidery generator. Unfortunatelly the color look completely different when I import this sbsar in Blender with the substance 3d-addon for Blender. Did any of you have this issue too? I use Blender 4.1 and the substance 3d-addon for Blender 2.0.0

Getting the following error:dlerror: dlopen(.../Assets/Adobe/Substance3DForUnity//Runtime/Plugins/libsbsario.dylib, 0x0003): tried: '.../Assets/Adobe/Substance3DForUnity//Runtime/Plugins/libsbsario.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '.../Assets/Adobe/Substance3DForUnity/Runtime/Plugins/libsbsario.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')) Is there no ARM support yet?  If not, what's the ETA for that?  M1 has been out for quite a while now. I noticed that there's a folder Arm64 with the libsbsario.so file but no dylib.  Can't seem to get it to work
