Normal and Occlusion Maps

Postby o4saken » Sun Jan 10, 2016 9:45 am

I decided that i want to learn to make normal maps, experiment arround with different methods, and see what i get. Hopefully in the end to be able to make some awesome assets.

Anyhow, first attempt was my more detailed male model skin texture, and then i decided to try it out on the elegant male suit.

I am posting this as work in progress as i will be adding more as i go along.


Here is the normal map/ occlusion map for the suit for anyone who is interested, as well as render examples with and without it. I set the normal map to strength 1.5, which is a bit strong but i wanted to see the difference.

Nice :)

If I remember correctly, those MH assets also already include AO and normal maps of their own, though I can't remember how they looked.

When i used the shorts it exported a normal map which was fantastic, but when i chose the suit for a design i was working on it only came with the difuse, thus i created my own. not sure if there is one, but i assume it would have exported were there one.

There are AO maps for the suits: http://download.tuxfamily.org/makehuman ... t01_ao.png
Why they are not exported, no idea. The AO map is declared in the mhmat file as far as I can see.

EDIT: My bad, that was the casual suit ...
Indeed, elegant suit has no AO map: http://download.tuxfamily.org/makehuman ... antsuit01/

My first attempt at makeclothes, thus i went with a simple t shirt.


I am not sure if the texture actually exported, thus i have included it in the zip folder along with a Normal and AO map.

Posting it here and not under user contributions as its nothing special and i plan on creating better stuff that i will upload to there.

Indeed the material file does not reference the textures.
A quick tip: if you enable the material editor plugin in makehuman, and restart, you can modify the material from there.

To fix the material, add the following lines at the bottom (to the .mhmat file):
Code: Select all

OK i need help, i am trying to make a jacket, but when i try to makeclothes it says that it cant as i have both tris and quads... Now i know you cant use tris which is why i was carefull not to get any.. i have rechecked and there really arent any.. its all squares, so why am i getting this error?

Are you sure you don't have a surface with more than four edges?

I didn't try (I'm at the office), but there seems to be a key combo for selecting all quad faces. If you do that and invert, is anything selected?

Really old docs though (scroll down to "face types") :

I usually use http://wiki.blender.org/index.php/Exten ... g/MeshLint for this. It can find both tris and ngons as well as other mesh irregularities that are probably not so relevant to MH but still are worth knowing of.
