how can i make a logo with the transparency?
i need to see only the logo and no other things on the texture.
i made the material putting the texture on diffuse and on opacity but with direct light system i see black effects beside of the logo.

instead if i use the path tracing everything is ok.

how can i do??

Short answer: Use path tracing. The direct lighting kernel doesn't support direct light passing through objects with an opacity map. (This is, because of a CUDA compilation problem, we couldn't solve yet)
