must a person first learn python and how to code in the bge before using stuff like parralax mapping or displace mapping?
This section is for community resources, if you are looking for help, a better section is the Support and Discussion one.
Parralax maps, displacement maps, etc are implemented via glsl scripts, not python. I am not sure however on the specifics of implementation. You could see how normal maps were implemented before the BGE got its GLSL mode, as they used to be implemented with glsl scripts then.
thanks! (I thought I was on the right section…oh well.)
