>> Question: Bump and normal and displacement are separate maps?I was under the impression they were the same thing.
In most cases we use a height map. From that height map a normal (bump) map is derived by the engine when using it.
Height maps allow for easy manipulation so that is why we use them (makes modding easier). This is why the texture has to be a
1 channel image.
When it is a 3 channel rgb image the software thinks its a normal map. So they can also be used directly instead of the height map.
>> Aare other maps supported? eg. reflection, transparency, specular..
Yes, when an color image is 4 channels the default is that the 4-th channel is the transparency. But by setting
Code:
color_w_type = SPEC;
in the shader (.ini file) it uses the 4-th channel as specular. You can also use a separate reflection file. Most metallic objects use them.
