no idea how to attach a material

I know it sounds painfully naive and dumb, but I have a material and no idea how to attach it to my Geo
any help would be appreciated

also my render tops wont show me a render anymore

Hi,

You can attach a material like the Phong MAT to the Material Parameter of the Geometry COMP.

Have a look here: derivative.ca/wiki/index.php?title=Rendering to get a quick overview of what is required to set up a render.
