Hi all,

I've modelled a lighter, made of transparent plastic. The dielectric material gives me nice refractions, but whenever I add more attributes to it, it won't render - MR will just freeze after a partial render (doesn't crash - but after a several minutes I just hit escape).

I've just added them as per a tutorial (create a reflect or transparency sample compositing node, plug it into the shader group then the material into that) but it fails.

Without them the dielectric is not so good - anyone know hoz to properly add to it?

thanks
