I’m trying to acheive a sprite type thing, by using planes as dupliverts from a particle emitter, and by mapping an image texture to them.
But I’v got a problem:
When I map an image (or movie) with a alpha channel to them (or just a normal plane which doesn’t move or anything), The renderer doen’t render the parts of the plane covered by the transparent part of the image as transparent.
Say you have a square plane in the view, with an image of a duck mapped to it, and that the duck pic is a targa of tiff, with only the duck opaque and the rest transparent. The rendered image is of a duck on a black backgrouns (which looks good), but if you only display the alpha of the rendered image, it is a white square on a black background, which is useless.
I’ve tried every combination of these settings:
Use image map alpha
map texture to colour and alpha
render with RGBA (into targa or alpha supporting mov file)
and so on
any help would be greatly appreaciated…
