An Update on Substance Format Support in Unity

Export Substance Materials In Unity AssetBundles Erorr!!

Hello,

I am trying to do a Unity Cloud Build to iOS on an AR Foundation project with Substance. Prior to the latest release (2.4.4 was what I had) I was able to get good iOS builds but now I get the following error:
❌; ld: bitcode bundle could not be generated because '/BUILD_PATH/<PROJECTPATH>/Libraries/Allegorithmic/Plugins/Substance/iOS/libSubstance.Engine.a(S00_EntryPoints.o)' was built without full bitcode. All object files and libraries for bitcode must be generated from Xcode Archive or Install build for architecture arm64
286: ❌; clang: error: linker command failed with exit code 1 (use -v to see invocation)
287: ▸ clang: error: linker command failed with exit code 1 (use -v to see invocation)

If I remove substance I get:
❌; Undefined symbols for architecture arm64
264: ❌; ld: symbol(s) not found for architecture arm64
265: ❌; clang: error: linker command failed with exit code 1 (use -v to see invocation)
266: ▸ clang: error: linker command failed with exit code 1 (use -v to see invocation)

if I build in XCode (with or without bitcode enabled) I get:
Undefined symbols for architecture arm64:

"_cppCheckDimensions", referenced from:

_NativeFunctions_cppCheckDimensions_m23DCDF6EBB913EA779654085FCDEB3F2A684D9E4 in Substance.Platform.o

(maybe you meant: _NativeFunctions_cppCheckDimensions_m23DCDF6EBB913EA779654085FCDEB3F2A684D9E4)

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)


ANY help on this is much appreciated.

 

@AcuityCraig I have the same problem (when building locally on a mac). Did you found a solution?

Undefined symbols for architecture arm64:

ld: symbol(s) not found for architecture arm64

 

@HaimBendanan no I have not. I made the decision to wipe substance from the project, remove its scripting defined symbols from the build settings (player settings > Other settings) and move on to other things till I get some kind of an answer.

 

Hey guys, today I managed to release an update to my Substance To Material asset on the store, I think you might be interested. It supports all Unity versions (including Unity 2018 and Unity 2019), and converts in bulk all presets of any substance into Unity independent materials
https://assetstore.unity.com/packages/tools/utilities/substance-to-materials-converter-118459

Feel free to let me know what you think

 

Same problem. Now i cannot build ios app....

 

I'm encountering the same issue. Failing in Xcode.

 

Hello,

I'm very sorry for this late reply. I missed these notifications on this post. Totally my fault.
We do have this issues resolved in our upcoming 2.5.1 update.


Cheers,
Wes

I use Unity 2018.4.20f but please look at below pic why it looks like this when I get close to wall? (It happens for all materials from substance database)

 

Hi, I tried to import version 2.5.4 into the newly created projects 2020.2 and 2021. Several times. I always got this message:
Failed to extract Substance.Editor.InspectorSubstanceImporter class of base type UnityEditor.Experimental.AssetImporters.ScriptedImporterEditor when inspecting Assets/Allegorithmic/Plugins/Substance/Substance Engine/Editor/Substance.Editor.dll
UnityEditor.AssemblyHelper:ExtractAllClassesThatAreUserExtendedScripts (string,string[]&,string[]&,string[]&)

I cleared the asset store cache and downloaded the plugin again, repeat. Architecture set to x86_64. Do you have any advice?

Edit:
Unity 2020.2.1f1 works despite error messages (manual copy .sbsar files).
Edit:
Substance materials appear to be incompatible with path-tracing?
Edit:
Unity material created from Substance is HDRP/LitTessellation. This shader does not appear to be compatible with path-tracing. If I change shader to HDRP/Lit, works fine.

 

I've had the same error (and in the same two Unity versions) and have found that my Substances still work despite the error, although occasionally I need to reimport a .sbsar file. Newly-imported .sbsar files seem to be okay for me. I've never needed to clear the asset cache, however.

I'm not using path-tracing in my current project, so I can't comment on that aspect.

 

Hi,
Thanks for reporting this issue. The devs are looking into this error message. For the path-tracing we need to take a look. Could you please post this support question in our thread here. https://forum.substance3d.com/index.php?board=6.0. I can then have the devs and our QA reply to your question.

Thanks!
Wes

 

Hi,

I am using sbsar files with 2k resolution for maps in untiy3d. The number of sbsar files loaded in a scene will vary. There can be chances that 8 to 10 sbsar files are loaded in scene simultaneously. I want to achieve below things -

1. I want to optimize the use of substance in unity3d so that application can run without any issues. Currently with 2k textures, whenever I change any values of sbsar file (eg. normal intensity), it takes around 8 to 10 seconds to show the effect and also a lot of cpu power. In some cases the application freezes and crash.

2. I have to bake the maps for all sbsar files in a folder by running a loop that goes through all textures of all graphs at runtime once all the tweaking is done. This process is taking a lot of cpu power and memory. I want to optimize this process. I have checked the substance in unity api but have no clue how I can optimize it using 2k textures.

Please suggest and help me to optimize it.

 

Thanks for reply.

- I think this is unity problem, not adobe (LitTesselation shader not supported by path-tracing). Path-tracing is not (yet) common mode.
Substance materials looks great in unity!

 

Hi, I upgraded your pluign to 2.5.4 version, but when I try to compile my project with XCode Archive I have an error:
bitcode bundle could not be generated because '/Users/massimosarzi/Documents/Unity/BiRingGit/Biuild/ios/buildIos/Libraries/Allegorithmic/Plugins/Substance/iOS/libSubstance.Engine.a(S00_EntryPoints.o)' was built without full bitcode

If I build directly on my Iphone this error disappear. What I have to do?

Massimo

 

This plugin is so slow and buggy. Takes two minutes to make a single change. Sometimes it just decides to do the two minute import without even making a change. My height map is suddenly missing, even though it's checked. Guess that's four minutes of importing to do!
EDIT: Nope, still gone

 

It can be related to Unity version. What version are you using?

 

2020.3.7
