Here's a good one. 3989 "stars". It's fun to travel inside.

The radial profile is an exponential probabilistic distribution (I removed the layers I was using at first). Should I use a gaussian (normal) radial distribution ?
Please, tell me what you think of this chip.
It may be usefull to know how this format (CMOD) is working, so here's a micro-tutorial. Below is a typical code for a distribution of dots :
emissive 1 1 0
diffuse 1 0 0
vertexdesc position f3 end_vertexdesc
0.8658485885146612 0.2426581291531574 -0.43751943285191164
0.09960431714365557 -0.8865045061998517 0.4518724825586342
-0.9508415773552661 -0.2907842543243548 0.10651202847368269
0.694091501772355 -0.5857211989415121 -0.41853036243254127

The red numbers are RGB color definitions. You can change them to any numbers you want, but they must lie between 0 and 1.
number is the transparency effect (alpha). You can change it to any number between 0 and 1. Of course, 0 means "totally transparent" while 1 means "opaque".
number defines the coordinates of dots (vertices, actually).
The number 0
defines the material assignement, which is declared in the header (0 is associated to the first material declaration, 1 is the second material in the header, etc...) In the example above, there's only one material definition.
The number 4
is the number of vertices which are rendered as "dots" (points). This number may be different than the number of vertices.
There are some other options for this format, which permits the definition of lines between vertices, dash lines, etc, but I will not describe them here.
