I'm using blender since few months. I've been seriously impressed with Blender. I want to achieve realism. But unfortunately, my game engine doesn't support PBR. It works on OpenGL 2, gltf.
So, I'm unable to use cycles renderer in the blender for my game engine.
Can I get realism without PBR on Blender Internal?
Can I use cycles in my engine (baking or other methods?)
How to fake PBR in my game engine, Godot 2?
Are Diffuse, Displacement, Normal, Specular and AO enough for Realism?
If I'm missing something, or some tricks, please do tell.
any help will be appreciated. Thanks in advance.
