If you go the the page you'll see that it is simply a greyscale image and I havent been able to figure out how to make the darker parts transparent- like the normal clouds.png in celestia...

Any help would be great thanks!!

Code: Select all
#! /bin/sh
jpegtopnm clouds.jpg > tmp1.ppm
ppmtopgm tmp1.ppm >tmp2.pgm
pnmtopng -alpha tmp2.pgm tmp1.ppm > clouds.png

ppmmake white 2048 1024 >tmp3.ppm

I have tried your method with photoshop 7, and the DDS plugin of nvidia. http://developer.nvidia.com/view.asp?IO ... ion_plugin
He works fine, but I can only save the image with trasparency in PNG.
Do you explain to a neofite, how to save the PSD file in DDS with transparency ?
