Alternative to animated Boolean?

#1

Hey everyone!

So we’re working on a medical animation where we’re showing a tool that is cutting away the surface of a bone. Immediate thought is using a Boolean but as expected, there’s flickering. Turning off High Quality doesn’t help. Is anyone aware of a better Boolean solution in C4D? We thought about exploring doing a texture approach with Proximal to control the Alpha channel but not sure that will work well in Redshift. I’ve attached a simple preview that hopefully illustrates what we’re doing.

Thanks guys!

Is there any reason you are not using Volume Builder/Volume Mesher combination in this instance as that is the obvious solution to your problem?

Perhaps you could use the Volume builder to do this. The Meshes are really good in the Volume Mesher( but dense ) and you have control over the quality etc.

Thanks guys! Explored this but it has a very detailed UV map so that’s out. Deadline was extremely short so we wound up having to do PLA animation which is akin to stop motion. Extra work but that was the unfortunate reality.

UPDATE: We settled on a solution using Fields and the displacement deformer. We took a setup that The Priest made last week for a different problem and tweaked it for something like this. A really simple and elegant solution, I hope this helps someone else as well. Big kudos to Priest, we didn’t even know a spherical point field existed…
You can adjust the roughness and cleanliness of the path it creates by adjusting the strength of the Spherical and Spherical Point fields in the Group Fields of the displacer.
