I assume that converting to a vertex object (not sure how that is done) would freeze the shape.  Is the ability to alter the topography the only thing I would lose in doing this?  In other words, can I still use terrain shaders on the vertex object and treat it like terrain?

Also, does this response indicate that there is no way to assign shader domains to a terrain?

Thanks.
