Please, can anybody explain me how to make a transmap?

It took me a few tries, reading SEVERAL threads about it, and looking at an existing map to figure it out AFTER having read the manual. I'd suggest searching through the archives here for information, unless there's a tutorial (check the Tutorials link), but I don't recall seeing one... It's one of those things that's easier to do than to explain... Essentially, you use the texture template for both transparancies and textures. The texture map you use normally, but the transparancy map you only use black, white, and - if you're adventurous - shades of gray. The darker the black, the "more transparent" it will be on the final render. Transmaps don't show up before renders, though transparent ITEMS show up as outlines only in most pre-render views. You also need to load the transmap into the transparancy channel on the Materials editor, and play with the sliders (for "standard" transparancy - i.e., a segment of the model is "gone" - your best bet is to make the transmap all absolute white and absolute black, set the minimum slider to 0%, maximum transparancy slider to 100%, and falloff to 0).

ruf, Check the tutorials section of the site. Stormrage did a couple of tutorials on transmaps. Do a search for Stormrage and it should pull both of them up.

I just created a trans map for the first time in order to make Vicki's bikini bottom into a thong. Since all it required was black and white, it was easy, I did it in Photoshop using the bikini texture map template. I created the cut-out shape in black for one side of the back, then duplicated that as a mirror image for the other side. Then I created a layer filled with white as the background for the transparency, to cover the map itself, flattened the image and saved it as a .jpg. It worked like a charm, and I didn't have to go to the trouble of creating a new prop. Gromit
