[Question]: How to create *.mat files #14

Closed Drjacky closed 2 years ago

Drjacky commented 2 years ago

I realized you have depth.mat, flat.mat, shadow.mat and textured.mat. I'm wondering how did you create those files?(that then we can build .filamat files with the help of the shell script).

zirman commented 2 years ago

It's built using matc from files in ./app/src/main/materials/. You can download compiled binaries for matc here: https://github.com/google/filament/releases

Make sure you download the version compatible with filament in build.gradle.

Copy matc into the root of the project and run this script https://github.com/zirman/arcore-filament-example-app/blob/master/build-materials.sh.

Okay, I'm confused! We have(how?) filamat files which after we use the build-materials.sh/matc, we get mat files? Or We have mat files(how?) which after we use the build-materials.sh/matc, we get filamat files?

Either way, how we get the first files?

I'm asking this because of two things: 1- When I replace your GBL with mine, I get this error after run:

    reason: uniform named "alpha" not found

2- If I want to update filament dependencies, I need to run the build-materials.sh Otherwise, I get an error:

reason: Material version mismatch. Expected 12 but received 11.
