Is it possible to set render modes through uniform variables or something.
I’ve created a volume shader plugin for Godot but don’t know how to change blend modes from gdscript.
I have the same question - I would like to “dynamically” set render_mode to cull_disabled based on a ‘uniform’ parameter set by the calling script.
I guess an obvious workaround is to duplicate the shader with appropriate variations (with or without cull_disabled set), but it would be nice to be able to change it dynamically.
Blend modes can be changed using keywords at the beginning of the shader:
I’m not aware of a way to choose blending using a uniform, even in regular GLSL.
I am aware that blend modes can be changed using render mode. What I a am interested in is how to change said blend modes outside of the shader.

I am not aware of a way to do this. It sounds feasible because normally, blend mode is not part of a shader, it’s part of the states set by the renderer when binding a material AFAIK. I wonder myself if that’s a feature to ask in the Godot API.
I also wonder why you want to change the blend mode of a ShaderMaterial dynamically? Just curious about the use case

Because I have this addon where I want to have the blend mode customizable. Just like you can change blend mode in a regular SpatialMaterial.
