Which GLSL versions can use in Vuforia Studio?
Hi,
I try higher version shader in TML (GLSL).
#version 300 es
After I preview the project, I got error message.
Compile error in vertex shader: ERROR: unsupported shader version
Hello William,
In a shader with this directive
#version 300 escan be only compile in a WebGL 2.0 context.
So, it is clear that Vuforia Studio and View are using a WebGL 1.0 context.
More details here :

Another way to check and who is more accurate, is to look in the libthingview_wasm.js file provided in each Project created.
We can found a function named createContext.
In this function, we can see :
var ctx = canvas.getContext("webgl", webGLContextAttributes);
So, it is webgl 1.0 used and not webgl 2.0.
Best regards,
Samuel
