Hiya,
I'm working on a lava splash texture for a computer games.
The way I generate the splash is I have an object colliding with the surface while it is spinning. The way I do is I have a Rigid Body Dynamic object.

However with the rigid body object I lack control. For example I want to shrink the colliding object or delete it after a few frames. I would also like to control the scale or rotation directly by hand. The reason is that I want to quickly grow the object to create an explosion.
What would be the best way to achieve this?

I'm currently testing using a static object and animate it. This seems to work if I enable velocity on the collisionsource node, but maybe it is not the best way?

Ok, static did not work great. But I found the deforming object in Collisions. This seems to handle scale and animation changes very nicely.
