I am trying to understand the question, in what case are you doing this? Are you using the load material ACE? In general the best initial load of textures should be done in blender and exported with embedded textures in the gltf, glb. Are you doing another procedure after that? Any screenshot or demo project, so I can understand the issue better?

Oh I see what you mean.
I was talking about using basic shapes: I want to create an environment with basic shapes such as cubes but can't use the one from Construct 3 directly because they don't support 3D rotation. So i wanted to use cubes rendered from Blender and change their texture directly from C3 (because I'll be using a lot of different textures).
But with what you said it sounds simpler to do it externally rather than build it in Construct.
