Hopefully it would be simple to integrate, as it's a simple texture overlayed with multitexture with a 1/8 texture scale, repeated. Probably would be GL and d3d only however since it's best worked with multitexture <!-- s:P --><img src="{SMILIES_PATH}/icon_razz.gif" alt=":P" title="Razz" /><!-- s:P --> I remember coding a thing like this back in 2002 on CheapHack, was easy to do. Just one problem - the flats, somehow need to avoid this overlayed on the water flats, and the transparent ones.

AFAIK, Vavoom actually supports PNG images and TGA images, I don't know if that's what you mean... The detail textures that Doomsday uses come in this formats, but I don't know if there's a way to load them to the game, heh! <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->

I mean "Detail" textures, as in a tiled texture of overlay grain or so. TGA, PNG or whatever, it should be an 8-bit grayscale texture. Here's an example of one: [img:2aj263xi]http://www.planetgargoyle.com/detail.gif[/img:2aj263xi][img:2aj263xi]http://www.planetgargoyle.com/detail.gif[/img:2aj263xi][img:2aj263xi]http://www.planetgargoyle.com/detail.gif[/img:2aj263xi] Also see Figure 19 here <!-- m --><a class="postlink" href="http://www.gamasutra.com/features/20010523/hajba_pfv.htm">http://www.gamasutra.com/features/20010 ... ba_pfv.htm</a><!-- m -->

It shouldn't be hard to implement.
