Surface with Transparent Background

[Anonymous]

Is there a way to make the white background of the logo transparent so you can see the corrugated metal as background? The logo is a surface applied to a smaller corrugated metal piece separate from the large corrugated metal panel.

Try using the alpha channel (load your texture in that channel) in the surface and make the delta white, also you might need to check invert, try playing with those values. If other color rather than the white gets transparent, then you will need an image of the logo in black and white and loaded into the alpha channel.

Arqrivas, thanks. Where do I find the Delta White, and the invert? I have attached an image of the surface setting that shows the Alpha Channel.
