UV Mapping problems

Can anyone help with Maxwell Studio V2?

I'm trying to render two products, in a single scene, which need the same logo/decal but in different locations. I was able to place the logo on the first object but I'm having problems with the second object, the second logo on the second object does not show at all.

Object1: The first material was made the same way as the second listed below, except with a channel number of 1. This one works fine as it should.

Object2: I selected the second object and created a new UVSet (cubic), scaled and positioned it with the channel set to 2. The Material is Chrome, One layer is Chrome (Nickel Plating) made of two BSDFs and a second layer white BSDF with a Opacity Mask of a black white logo (jpg) channel also set to 2.

Here are screen shots of the material setting.

If the above is too confusing, could someone be kind enough to list the proper steps for creating and placing two logos on two separate products...or point me to link that might already cover this subject?

Thanks

1. Unwrap your model, at least the poly's that need the logo on them.
2. Make sure you place the poly's from each model on the same coordenates.
3. Render out your UV map.
4. Use photoshop (or paint) to place the logo in the spot where the poly's are.

Or unwrap them both and place each logo individually in the right place. And create 2 materials.

Thanks for the reply Tok_Tok.

I'm afraid I don't know how to unwrap the model. As far as I know my 3D software (Alias Studiotools) does not have that function and Maxwell does not do it as well. What software would I need to unwrap the polys, do you have any recommendations?

I myself do not use external unwrap software. 3ds Max already has a great tool build in. :)
So i don't have any recommendations for but, have a look where google gets you ;)
