Unity Substance Plugin freezes when changing parameters on runtime (Android)

[MalteDe]

Hello 🙂

I am currently working on a android game trying to change substances in runtime.

The substance is referenced by a script when I build the game (Caching Behavior paragraph) (https://substance3d.adobe.com/documentation/integrations/publishing-for-mobile-172823474.html).

When I use the "Simulator" of Unity to test the game everything works fine - the textures are generated.

Building works fine without any Errors, but when I start the game on android (Huawei P40 Pro) then it freezes.

1.) Do I have to put the .sbsar files in a specific folder so that they work runtime?

2.) Does anyone have the same problem?

3.) Is this a known issue and will it get fixed?

Thank you for taking your time to read this message, I am looking forward to a reply :)!

Hey @MalteDe

Do you have this problem with this .sbsar only? 

Did you try any Substance materials from Substance Source to see if they work?

Does this work on your Mac or Windows machine and only freezes on Android?

What happens if you remove Substance plugin and build your application without Substance? Does it run on your Android device without any problems?

What version of Unity are you using? 

To answer your question regarding location of the .sbsar file, you can drag and drop your .sbsar file on Assets folder. 

Thanks,

Hey @Alireza5EAF  🙂
Thank you for your fast answer!

My Unity version is 2021.1.15f1

It doesnt work with other .sbsar files after building it for Android.

I ran it on my windows computer, and it worked on it. it worked aswell in the "Simulator" mode on various simulated devices, and only freezes on my Android device.

I tested this one from substance source aswell (https://substance3d.adobe.com/assets/allassets/e9adbcd1c283253a54c01a61a3fa5216a5d3e4db) That one even gave me a "Microsoft Visual c++ Runtime Library Runtime Error!" in the editor in Play mode (Windows) after changing the randomseed value which crashed unity (reproduceable). And it doesnt work for my Android device.

After removing any code related to the plugin it worked just fine on Windows and Android and after removing the Plugin everything worked fine aswell.

I really hope that this gets fixed, because I really love the way the plugin is designed and am very grateful that you guys developed it, but unfortunetly I cant use it in the current form.

Thanks alot!

The SubstanceGraph.RenderSync() command doesnt work for me aswell (on Android).
