you can assign just one material to the object.
within that material, you can assign as many textures as you want to as many
projections as you want. You can assign a material to a cluster, containing
a selection of polygons from the object.
again with as many projections as you want.
You cannot apply a material to a projection. This just doesnt make sense.
A material is applied to an object or a cluster.
A projection is a property of an object. (actually it is a cluster I think,
but that just makes it more confusing)
There is no immediate link between materials and projections, allthough
within a material you can define what textures use what projections.
perhaps try to explain why you want to do this / what you are after to
achieve.
I do have the feeling that you want to assign your material with the
original texture, and corresponding projection to the object, rendermap this
to another texture, using a second projection, and then assigning this to
the object to see the result. If so, a good method is making a second pass,
assigning an override material to the pass, and assign the texture on that.
So you can switch to the original pass and see the object with the original
texture, and then switch to another pass and see the object with the
rendermapped texture.
