I am new to the 3D world and am exploring ways to embed alpha cutoff and double-sidedness into different file formats. I know that gltf allows us to specify alphaMode, alphaCutoff and doublesided value. I wanted to know if there is a way this can be achieved in the obj format. More specifically, I want to know if I can simulate setting alphaMode to "MASK" and specifying the alphaCutoff value and enabling/disabling doublesided flag of gltf in an obj file.
Is there anyway this can be achieved?
