Fragment shader is not compiled.
WebGL: INVALID_OPERATION: useProgram: program not valid
v3d.js:1 WebGL: too many errors

What is the procedure to correct this?

According to https://www.soft8soft.com/docs/api/en/renderers/WebGLRenderer.html#debug

.debug : Object
checkShaderErrors: If it is true, defines whether material shader programs are checked for errors during compilation and linkage process. It may be useful to disable this check in production for performance gain. It is strongly recommended to keep these checks enabled during development. If the shader does not compile and link – it will not work and associated material will not render. Default is true.

But it does not describe how to “disable this check”

How do I determine what is the cause of this error?

Thanks.

app.renderer.debug.checkShaderErrors = false;

but it’s not a solution in your case. it won’t remove errors in shaders.

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

Hi there,

The error is probably caused by incompatibility of materials exported from Blender and Verge3D runtime. Please make sure that

1. the app was updated in the App Manager
2. the gltf was exported using the Verge3D addon of the same version

So in the browser console, there should be something like Verge3D 4.7.1 License, and the Verge3D addon should have version 4.7.1 in Blender.
