Subject: texture map hell

Ok heres my problem. I have a t-map of a pic and an alpha for it. I place the t-map on a plane just how I like. Now how do I get the alpha map to line up exactly in the transparency channel? I keep reading that you can copy the settings down but I dont ever seem to get a way with that..is there some sort of trick to it? Up 'till now I have just worked around the issue but I need to figure this out today for a project I am working on.

Brent, If the Alpha map is the same size as the image I don't know what the problem would be; I should import correctly. If they are different sizes, open the picture in your paint program, import the alpha and make adjustments in the paint program to fill in any mis-alignments. Save off the new Alpha and everything should be hunky dory. If you've done all this, post a pict of the shader tree and we'll see if anything stands out.

Hi Brent, I'm not sure of what you're looking for ... Did you use a rectangular layer to apply your T-map in a particular area of a shaded plane ? Or did you apply the map to the whole plane ? I got a solution for both but i'd like to have more details on your problem . If it's the first case, you'll need to copy the rectangular layer to its opacity channel by holding Ctrl while you drag it . Then, in the opacity channel, you change the T-map to your alpha map, and apply the same settings as the T-map . In the second case, you will need to manually apply the same settings (rotation, tiling) for the T-map and the Alpha map . Both cases need some little tricks, and i'd like to show you a capture of the shader tree to help clear things up . So tell us what kind of effect you're trying to achieve ! litst
