Maya to renderman - shave instanced geometry

[keith-andersen]

greetings

I'm haveing some drama rendering a grass setup I've made using shave and haircut.

Basically I've created blades and pods of grass that I'm instancing in Shave and haircut. This works fine in maya render but I want to render in renderman. When I do the result is bleached out showing no texture - just the silhouette of the geometry

any ideas

also it seems shave  doesn't instance nurbs - is that right

thanks in advance
