Inserting Vray materials to bongo

what is the best way to delegate Vray materials to finished animation with keyframes set. Can I just layers from layer list and assign material which will not effect key frames and will cover all animation period.


You can change materials by using layers that can be easily turned on/off with keyframes.
You can also animate the properties of a material (color, transparency …) but only in certain renderers that support it.

Thanks that works. But unfortunately I created may blocks. Which are very resistive to accepting material definitions after blocking them.
