.Map :: MoHAA Mapping

I do.

Actually, all that's needed is a basic knowledge of TIKIs, shaders and a little bit of artistic skills.

The fog isn't too bad I think... though you really need to add another layer to that sand ground texture shader (maybe even same texture but scale it up much... then blend with const alpha) so that it doesn't look so tily.

So what would I have to do 1st, to turn let's say the german worker into a cowboy?

Ooops, u said so before and u were right. I forgot to do this, but now, I don't know what such a shader would look like. Using the same (stock) savel texture again and blend it? Wouldn't it have to have an alpha channel?

A micro skinning tutorial:
1. Make a proper directory structure somewhere, eg.:

Code: Select all

c:\cowboy---+
            |
            +---models---+
            |            |
            |            +---player
            +---scripts
            |
            +---textures---+
                           |
                           +---models---+
                                        |
                                        +---wildmaps

2. Extract the TIKI of the player model you want to edit (e.g. models/player/german_worker.tik and models/player/german_worker_fps.tik) to c:\cowboy\models\player.
3. View the TIKIs, track down the shaders and textures for them.
4. Do whatever you like with the textures.
5. Make new shaders for them.
6. Change the TIKI's name and edit it so that it contains the right model and surface definitions.
7. Pack everything into a .pk3.

You can fake an alpha channel with alphagen in the shader

, e.g.

alphaGen const 0.5

creates a constant mid-tone alpha channel

@jv thanks a lot. So I made a shader

Code: Select all

textures/savel/saveltest
{
	qer_editorimage textures/algiers/savel_1.tga
	qer_keyword rock
	qer_keyword wall
	surfaceparm sand
	surfaceparm trans
	{
		map $lightmap
		rgbGen identity
	}
	{
		map textures/algiers/grndset_2af.tga
		tcMod scale 0.7 0.7
	}
	{
		map textures/algiers/savel_1.tga
		alphagen const 0.5
		blendfunc blend
	}
}

Is this it? Or is there a better way?

hehe, thanks! Maybe a bit too micro for my microbrains, but I'll try my best.

not sure if this was what jv was helping with but an overlay texture might be good to break any monotony.

just a basic texture like any other, only difference is it has a lot of holes and such and is used exclusively as a notsolid brush, like adding quick rips and holes in walls without making a new texture

Yes that's about what I had in mind Wacko

Only atm you are rendering 2 opaque maps over each other (1st and 2nd stage) so you'll see the first stage (lightmap). Hence bring the lightmap down and blend it.

Code: Select all

textures/savel/saveltest
{
   qer_editorimage textures/algiers/savel_1.tga
   qer_keyword rock
   qer_keyword wall
   surfaceparm sand
   surfaceparm trans
   {
      map textures/algiers/grndset_2af.tga
      tcMod scale 0.7 0.7
   }
   {
      map textures/algiers/savel_1.tga
      alphagen const 0.5
      blendfunc blend
   }
   {
      map $lightmap
      rgbGen identity
      blendfunc filter
   }
}

Scale of the large texture can probably be much larger (smaller number) than 0.7 too

I tried both in a test map next to each other and I can't see any difference ingame. Did I miss something?

jv_map wrote:Scale of the large texture can probably be much larger (smaller number) than 0.7 too

Mmm, I tried some other values and 0.7 looked best imho, around 0.2 looks kind of washed out... Is there a way to rotate one of the stages (not making it rotate

) to reduce the tiling even more? Couldn't find anything in the Shader Manual

Uhm... did you light the map?

tcMod transform can do it... but it's a little tricky to use

experiment a bit I'd say

Well, I did light the map, but there was nothing that could cast a shadow, so that's why there was no difference.

Ok then, thanks a lot for ur help.
I'll start playing around with tcMod transform now

Posted: **Sun Apr 10, 2005 10:45 am**

I'm done with playing around

Code: Select all

S' = s * m00 + t * m10 + t0
T' = t * m01 + s * m11 + t1
This is for use by programmers.

This strongly makes me remember that I am NO programmer

What is s? what is t? what is my name?
Calling it "a little tricky to use"... Imagining to change parameters, compile, start mohaa to check - again and again for the next 2 years... no thnx

You don't have to compile again...

... vid_restart will do

Hell yes, u're right (again

). This way (and having two pcs) it wasn't that hard though I had no idea of what I did all the time

.
After doing quite a lot of shaders that do need a recompile, I didn't dare to believe this is possible
