Is anyone familiar with what lines in the effect file designates which portion of the effect texture .bmp the "particleattrubutes" uses?  Most of the textures have four images, one in each quarter, of the .bmps. 

What I'm trying to figure out is how any given quarter of the .bmp is referenced in the codeing.

(I've already went through the effects SDK, it's not too much help in that area.)

Disregard!

  JoBee supplied the info.

Sorry i missed this! 

In the "effect" file, each element is made up of three sections, [emitter.x], [particle.x], and [particleatributes.x]

In the [particleatributes] section, ther are two lines:

uv1=x.xx, y.yy
uv2=x.xx, y.yy

UV1 is the lower left corner, and UV2 is the upper right corner of one quarter of the texture BMP.

So, upper left quarter of the BMP would be

uv1=0.50, 0.00
uv2=0.00, 0.50

Upper right would be

uv1=0.50, 0.50
uv2=0.00, 1.00

Lower left would be..

uv1=1.00, 0.00
uv2=0.50, 0.50

and lower right would be..

uv1=1.00, 0.50
uv2=0.50, 1.00

Again, sorry I missed this.  I only happened across it while looking for ShaneG's "Adventures in GMAX" thread.  Has anybody seen it?
