alpha channels using photoshop CS2, and Max 8...

almighty_gir

so, is there any reason why any time i want to make alpha planes for hair in max 8, using CS2, that the tip of the planes has a non-transparent line? i've checked the alpha texture, and its pitch black, so it should be transparent. but for some reason it isn't.

i never had this problem when i was working with photoshop 7 =/

When the texture is filtered by a 3D app, the edge pixels will pull in the opposite-sides' colors.

To avoid it I scale the UVs down a bit, a couple pixels away from the UV 0-1 box.

it is either .png or.tga files in Max have a one pixel error at thier edges on the alpha.

If the problem is filtering, like Eric mentioned, you can turn it off in the bitmap properties section of the material. It defaults to Pyramidal (or something like that), so change it to None. Try turning it off in just the opacity map and see if that helps. Haven't tried it myself but it's worth a shot.
