Flamingo materials & blocks

Wondering which is a\the best way to use Flamingo materials while creating a Block instance.

I add materials to a Rhino solids, then create a block from all solids.

I then embed the block into another file. When I try to render this file not all materials from original file render. They do not show up in Flamingo Control Panel. They are shown in the layer dialogue box though.

Any thoughts? Is this a Flamingo issue or is it withe the block?

Thanks, Randy
