Alrighty folks. I have been trying to get the alpha mapping on an object to work. I’m trying to get the object to essentailly have a hole in it to see through to the object underneath. Unfortunately, it’s not working. I’ve tried every method I could find a tut or thread on, and nothing as of yet. No transperency, just a kinda milky surface where the hole should be any suggestions?
EDIT: More info
I couldn’t use the simple way of just cutting a hole in the mesh because the “hole” has to appear to fade in and the only way I’ve found to do it is through alpha/transparency mapping (unless someone has a better way?).
So I have a tga image with a nice transparent hole right in the middle of it for the “show-through” portion of the object, and I have the imaged mapped to color and alpha, and have the texture set to calc the alpha and use it <–update: that wsa wrong turned off calc alpha, much better effect. DVar is set to 1, and alpha is of course to 0. ( I so have to get a good screen cap prog, any suggestions?) Now every time I do a test render the hole seems milky opaque, you can almost make out the object beneath, ALMOST.
So I hope someone can help me out with this because I’m ready to remove what little hair is left on my scalp with a violent upthrust from a clenched fist.
EDIT: Even more info
O.k. After monkeying around some more I find that where the transparent portion should be is just being filled with the world color. MONGO CONFUSED!!!?
