Long time ago, I bought a scifi models pack from dexsoft.
I used them to toy around a bit

The mdl file contains a single skin which contains the color.
There are 3 additional files for
- height
- spec
- normal

Is there a single shader available which supports to use all 4 maps?

If I create my own models, should I go the same way if I want to sell them? What is the best combination for users who don't want to code at all?

more questions:

If I have a flat table and a hightmap which "extrudes" a block in the middle of the table - what will be shown at the sides of this extrusion? Or am I missing something? Is the height map just for shadows?
