This is pretty basic, but the kind of thing I haven't done in Carrara... have done it often in Rhino...

I need to take a logo and place it on the side of a helmet (helmet is red or whatever) and have just the logo (no square background) appear against the red of the helmet.

I know it involves using a texture map with an alpha channel, but just can't quite get it right.

I'm stuck with using Carrara 4 pro for this series. Carrara 4 pro apparently will not open the newer Photoshop PSD files.... I have tried png files, but I'm obviously missing something... I don't want to get into uv mapping, unwrapping, etc... not necessary for this.

Any simple 1-2-3 steps that may help get this moving?

Thanks

Here's an example (Helmet made in Rhino... rendered in Carrara)
