Experimental support of parallax mapping in 2.13

[Arcturus]

One thing I wanted to test was .md5 meshes. Parallax mapping doesn't mesh very well with them, but if you crank it up to 11 you get something that looks like polished metal. Of course you can forget about proper texturing, but it reacts to light believably.

It definitely bends weird in this case. But conceptually it's pretty good and doing its job best it can: Still impressive to see something like that in TDM!

[Arcturus]

UV seams are very visible. Other than that I think it's usable.

Here's the material:

textures/test/parallax_gold
{
	diffusemap	textures/test_parallax/parallax_gold	
	{
	blend specularmap
	map _white
	rgb 1
	}
	{
		blend parallaxmap
		map textures/test_parallax/parallax_gold_height
		min -1
		max 1
		//refineSteps 5
		//linearSteps 20
		//grazingAngle 0.3
		offsetExternalShadows 0
	}
}

I used two noise textures made in GIMP: https://drive.google.com/file/d/1O77ZcNIkYetGk_w_53JXgwpntwOyEkKJ/view?usp=sharing

Generally .md5 mesh will look like any other geometry as long as it's not deformed by animation:

It would be nice to see a performance comparison on that. A scene with typical materials vs. parallax versions. R_showprimitives, CPU and GPU utilisation increase, stuff like that

I lied. Actually parallax mapping works fine with animated .md5 models.

There must be something else going on with the builder model, and now I wonder if it has something to do with this situation:

With lower specularmap values looks like it's a bit rougher.

Continued in this thread.

This will be great for an acid trip \ hallucination based mission!

At last: We have Mandrasola consumption implemented in TheDarkMod

Could you please explain where is heightmap used on the builder model?
How does it look without heightmap/parallax?

@stgatilov Builder guard has a uv seam in the middle of the chest and the texture is mirrored, so that thew me off. I don't think it works well in cases like this, but as my later video shows parallax mapping generally works with animated md5 meshes. And just to be clear, I'm not saying we should put it on our characters, I was just experimenting. That video of the builder shows parallax mapping with extreme values, because I found it interesting.
