Forcing brute force on an object... how to?

[Deflaminis]

you can fake the gi contact shadow under the feet/car using vray dirt maps on the materials below, set to be affected only by the animated object.

Smart, never thought of that. Always rendered a shadow matte pass but for some simple projects this seems way better.

i use it generally for people, cars etc on large landscapes. works perfectly.

Got it. Thanks.
