I got a texture map that is in Tiff format with a alpha channel with it.
The RGB channel is red, alpha channel is just painted with a big white dot in the center.
Then i apply to a sphere, What i want do is to have the white dot on the sphere. The rest are transparent.
What i get now is either the whole sphere get transparent or thing is transparent.
how do i apply and arrange the render tree to get the effect that i want.
i've checked ed's website. It doesn't have any tutorial that talks about it.
Plz help, urgent!!!thanks thnaks:cry:
