Master Material - Additional texture switch for Material Instance

Hi,

I’m setting up a master material and I have started using Static switch parameters use load in textures instead of colour values if required in my material instances.

However, because I am setting up a master material which will blend multiple textures together, for example a master stone material that is used on several meshes with their own normal maps. I want the option of loading an additional texture by simply checking the relevant box in the material instance which then blends the materials. This works as intended, but I need to have a blank normal map until I choose the relevant texture to replace it if required.

Would this be similar to how the Static switch parameter works? I assume I need something like an ‘if’ node that will allow me to load a texture parameter if its ‘true’. Otherwise, nothing at all is read and visible in the material instance.

Any help will be greatly appreciated.

Thanks,

Well, the only thing you have at your disposal is static switch parameter and you should use it for this case.
