To repro, make two changes before building filament:
- In
gradle.properties, changecom.google.android.filament.dist-dirby replacingreleasewithdebug. - Change first constructor in
ModelViewer.ktby passingEngine.Backend.VULKANinto Engine constructor.
This can actually be repro'ed with a release build:
- just use the
-doption when invokingbuild.sh - if using Android Studio, you also need to set
com.google.android.filament.matdbg=trueingradle.properties
For record. It seems adreno vulkan compiler has a problem with shaders of the following form:
#version 450
out gl_PerVertex {
vec4 gl_Position;
};
highp vec4 m1(const mat4 inm, vec3 p) {
return inm * vec4(p, 1.0);
}
highp vec4 m2(const mat4 inm, vec3 p) {
return inm * m1(mat4(1.0), p);
}
void main() {
gl_Position = m2(mat4(1.0), vec3(0.5));
}
where two methods have const mat4 and one calls the other. This adjusted version does not crash:
#version 450
out gl_PerVertex {
vec4 gl_Position;
};
highp vec4 m1(const mat4 inm, vec3 p) {
return inm * vec4(p, 1.0);
}
highp vec4 m2(mat4 inm, vec3 p) {
return inm * m1(mat4(1.0), p);
}
void main() {
gl_Position = m2(mat4(1.0), vec3(0.5));
}
We use const mostly as a best practice and in the hope it will help compilers. We could get rid of them, I don't think they have any actual impact.
Running spirv-diff on the crashing vs. non-crashing version, we get
