Hi,
I have the following problem:
I want to have a logo mapped on a 3D object with a shiny surface.
I want to see the shiny surface AROUND and not BEHIND the logo (no transparency and no reflection on the logo). So I have a reflection map for the surface, but this reflection map also apply on the logo.
I tried to make an alpha channel on the logo with the the "texture lab" on the scene builder, but it doesn't work.
Anyone has an idea on how to do that?: have an "alpha mapped" logo that is not affected by the reflection map of the surface it is mapped to ?
Thank you for your help.

Sushi,

The best ways to do what you are looking for are to create a second object floating just above the shiny surface and place the logo texture on it with an alpha channel.

--or--

to cut the logo into the geometry and apply a separate material to it. Then you would be able to apply a separate lightmap (flat) to it. Lightmaps are applied to materials. So if the area you want to make shiny and the area for the logo are the same material, then the lightmap will be applied to the entire material over both areas.
