This page is a tutorial on how to create and use a glow mapped texture. you'll cover creating the texture and loading it.

the tutorial covers basics of setshader and setpixelparam, and some of the texture command

A Tutorial written by Hirato Kirata 
 
 
 
This tutorial requires the following tools (or tools with similar
functionality), or traits 
<ul>
<li>The gimp (you can attempt paint, photoshop, etc)</li>
<li>basic ascii text editor (like Kate. notepad, etc), do not
use MS office or OOo</li>
<li>relative competency in finding files and directories</li>
</ul>
Today I'll demonstrate how to create a texture, that'll glow without
the need for lightmaps. This is done by using glowmaps. 
 
1. First of all, we'll need to make a directory for all the files. Go
to the directory to where PAS was installed in. 
Once there, go into the folder named "packages" and create a directory
named platinite within it 
it should look similar to this 
 
[[image:glowmap1.jpg|none]] 
 
2.
next up, we need to open up the gimp, and tell it open a new image.
When asked for height and width, enter 32 for the width, and 16 for the
height. 
Once you've done that, just zoom in a few times, so it'll look like
this. 
 
[[image:glowmap2.jpg|none]] 
 
3.
Next up, we'll need to select an inner area, roughly 26x10 pixels. Use
the rectangle tool (R) to make a selection, with each corner, being 3
pixels from each of the image's edges. 
We should have something like this afterwards, ready for colouring in 
 
[[image:glowmap3.jpg|none]] 
 
4.
now to colour in our image. Select black, and colour the whole middle
area. Afterwards, press ctrl + i, and colour the border a darkish grey. 
You should have something similiar to this now. 
 
[[image:glowmap4.jpg|none]]
 
 
5.
next up, press ctrl + a, and  just blur it once with a filter,
to
give it a bit more softness, and then save it as "lighta.jpg" in the
folder we created at step 1 
The image just shows which blur I'd like you to use. 
 
[[image:glowmap5.jpg|none]] 
 
6. Next, under the blur, and select the inner bit, with colour select
(Ctrl + O). 
Colour that in yellow 
Invert the selection again, and colour the outer bit black, as we dont'
want that to shine. 
Now, select all again (ctrl + a), and run the blur filter 3 times. 
The reason for the blur once again is to make it look softer. 
The images should now look like this, save it as lighta_g.jpg. 
 
[[image:glowmap6.jpg|none]] 
 
7. feel free to close the gimp now, but we're not done yet. 
Go to the directory we created at step 1, when in there, create a new
text file named "packages.cfg". 
I can't stress it enough to make sure the extension is CFG and not TXT. 
 
[[image:glowmap7.jpg|none]] 
 
 
8. Just open it up in a text editor. We'll need to load the images. 
once open enter the following lines. 
 
setshader glowworld 
setpixelparam 0 1 1 1 
 
texture 0 "platinite/lighta.jpg" 
   texture g "platinite/lighta_g.jpg" 
 
The
setshader will set a shader for the textures to use, here we're telling
it to use the glowworld one, which takes a texture, and one in a glow
map slot. 
The setpixelparam is a command that sets attributes of
certain shaders. With glowworld, param 0 is the glow colour. As we
already set the colour in the image, just leave the RGB at 1 1 1. 
texture 0 loads a new texture 
texture g loads a glowmap to use with the last texture loaded with
texture 0 
 
we should have something similiar to this now. just save it 
 
[[image:glowmap8.jpg|none]] 
 
9.
We're not done yet. We still need to put this in a map cfg. But I
suspect there's no point in that. so return to the base of your PAS
directory, and go into data. 
We'll be modifying the defaults here. So open up
default_map_settings.cfg with notepad or something already. 
Add the line 
 
exec packages/platinite/packages.cfg 
 
At the very end, similiar to below. 
 
[[image:glowmap9.jpg|none]] 
 
we're
pretty much done now, congrats, just launch PAS and marvel at your
work. Note you won't see the glow till you calculate lightmaps

Hope you learned something today :)
