Bake glsl shader into a Texture?

[Dipesh_Dulal]

Are there any examples of this approach? I am confused.

I have a GLSL material and want to export baked in texture since, GLSL material applied to a mesh can’t be exported as GLTF files.

After creating a second canvas with preserveDrawingBuffer to true. How does one extract the texture information say as a png for use the baked in texture for GLTF files. ?

This is something that I have been trying to do and came across this thread.

Export the scene with custom shaders and canvas texture

I have a scene with custom shaders applied to a material and I use canvas texture to pass it inside the fragment as a uniform. I want to export the same scene. What type of exporter should I use or how should the export be done? I have searched for the solutions in the forums but looks like it’s not possible using custom shaders. Any ideas? I cannot remove the custom shaders as I have an algorithm that calculates the uv coordinates and to avoid texture stretching I have put logic inside fragme…
