Welcome!
Step 1: Choose ONE software to learn*
(*If you are new to 3D)
Keep it simple, no need to learn multiple at once.
I recommend Maya for those looking for general 3D (animation, VFX).
Unreal for those inclined towards Gaming.
Katana, Arnold, Redshift – are renderers. To begin, I would stick with Arnold that comes with Maya to simplify.
Step 2: Power of Light
The Power of Light course will give you the foundation for the art of lighting.
With those two elements – you will set a great foundation.
Happy Lighting!
