Shadeless 3d models... how to fix?

[Okuni]

Ok. I'll cut to the chase....

I know how to import models into gzdoom (Using IQM). Now... since I only use the diffuse image of the model I can see that the 3d model looks shadeless.

I've seen the textures that some mods like "Samsara reincarnation 2" or "DOOM 3D"use with their models.

My question would be... how?. AFAIK... some models that I want to port into GZDOOM uses normal maps. And as far as I can tell, it is quite difficult to put those maps into a 3d model using gzdoom(Or maybe I'm just not well informed at all about these type of maps).

I've heard that you can extract some of the channels of the normal maps and "fake" some depth into the model (With photoshop). But still I think that I'm missing something.

Can you help me out here?.

Yeah... I stumbled across that article weeks ago. Thank you for pointing it out.

Guess that I have to make a deep look to shaders (So I can know how to use them).

Thank you for taking the time to answer my question.
