crash inside compile => [UmbraShader.compile]

FMotalleb commented 2 years ago

I manually converted a shadertoy glsl to Umbra compatible file and received this exception

please note

I can generate a dart file from examples given in this repo and run the example app
I can generate a dart file from the hello world template of Umbra template and run the example app

I faced an error during the installation of Umbra

umbra install-deps
✓ Dependencies downloaded (1016.4s)
⠧ Extracting dependencies...Killed

I installed glslc manually into the Umbra (~/.umbra/)
I faced this exception one more time when I tried to use another shader from shadertoy

Exception:

an exception has occurred.
TranspileException (59: 6 is an unsupported Storage Class)

based on: this twit the issue is the glsl file that I am using is referencing an unsupported method "mat2"
