* Re-organize Android Gradle files Clean up our Gradle files, share versioning, etc. and prepare for publication to sonatype. * Use androix annotations for desktop * Add samples as subprojects to root Gradle * Fix build script * Don't break when samples aren't compiled * Better organize the Android Studio project

// Simple lit material that defines 3 parameters:
|
|
// - baseColor
|
|
// - roughness
|
|
// - metallic
|
|
//
|
|
// These parameters can be used by the application to change the appearance of the material.
|
|
//
|
|
// This source material must be compiled to a binary material using the matc tool.
|
|
// The command used to compile this material is:
|
|
// matc -p mobile -a opengl -o app/src/main/assets/lit.filamat app/src/materials/lit.mat
|
|
//
|
|
// See build.gradle for an example of how to compile materials automatically
|
|
// Please refer to the documentation for more information about matc and the materials system.
