Bumpmap: Convert your texture map to grey scale, and then invert its colours, to make it a negative image. Save it and load it as a bump map; Poser will ask to convert it to a BUM file, so let it do so. Dark areas will be lowered, light areas aill be raised (or is it the other way around?lol) Transmap: Black is transparent, white is opaque (black is what's transparent, white is what's visible). Use your selection tool in whatever program you use, and select around the template. Fill the template areas with black (RGB 0,0,0). Then invert the colours of the image (turn it negative) so that the template areas are now white and the surrounding areas are black. Now, say you want rips in a dress: use black and draw the rips and tears within the template areas. Save the file. In Poser, in the material editor, load the transmap into the transmap box; set transparency max to 100% and make sure the highlight is set to 0%, and is black in colour. This is how I usually create transmaps/bumpmaps. Some people say Poser doesn't do bumpmaps well, but I'm a relative newbie to these areas and I don't know how else you can do them. Hope it helps :) JoeBlack

In p5 a bump isnt inverted. Black is negative, white is positive. Just desaturate your texture in photoshop then kick up the contrast and lower the brightness a bit. Fiddle as needed/if needed.

Annette - the best way I've found to create transmaps is with a vector point-to-point line tool. That way the points are editable and I can make sure seams match-up, among other things. I always 'draw out' my transmap on a copy of the template and load that as a texture.

Both Photoshop and Paintshop Pro have vector tools (as, I'm sure, do other graphic editors) and it was (literally) an epiphany for me when I started using vector lines to do my transmaps.

I've a basic tutorial for PSP on my site. It's the first in a series of three on this topic. The first tutorial is long, but it really does ground you in the basics. The next two are/will be more tips-and-tricks oriented. You can find it here, at the bottom of the page: Wax Textures

In any case - good luck!
Regards,
-Nancy.

Thanks to everyone. These are all great tips. I am in the process of creating my own textures and I know these will come in handy. Was working with Vicky and I just knew I has to learn how to do a trans map for those eyelashes. :) Thanks a bunch! Annette
