How to animate Season?
The Leaves change colour when seasons change. This is what we need to do. Go to the Maps rollout and in the diffuse slot click on mix map. Mix map uses two colours, colour1 uses bitmaps and colour2 uses a gradient ramp. click on the gradient ramp in color2 map slot and adjust the colours and see the colour of the leaves change. The max files comes with both the materials for your reference.
