I'm thinking about making some mini game systems for -mostly- visual purpose (portfolio), and i was wondering if :
- it's possible to extract independently the R, G and B channels of a texture to treat them separately (with shaders) ?
- if the size of a texture used in a level should be using a power of 2 (128*256 etc.) to increase performances ?
- if construct can work with tiling textures the 3d way (you can tile as many time as you wish a bitmap on a defined surface)
- if it is possible to post process the entire screen at once (lens vignetting) ?
Thanks in advance.
