tyBoolean issue

[TubeSmokeGuy]

Hi!

I made a simple flow with some animated objects as shape geometry and returned them back via export to objects as reference nodes.
The exported objects work fine, but as I picked them in tyBoolean to fuse them together, there are some crazy mesh distortions and gaps from the point on when they collide.

Don't know if this is a bug or just normal behaviour.

I attached a small video and the max file here.

A union of concident faces like that is basically the worst-case-scenario for a CSG operation and it is guaranteed to have a high failure rate.

I would recommend moving to a VDB workflow in tyFlow for something like that - you won't run into the artifacts. The downside is that in order to preserve the hard edges you'll need a decently hires grid.

Indeed I allready tried the VDB alternative but as you said i had to raise the voxel-grid resolution very high for keeping the crisp edges. When I cache it out the last few VDB frame files reached over 100MB each. Additionally I had the issue that I don't get it stop calculating after it has reached its final desired form.

I asked for that in these threads:
Crisp edges: http://forum.tyflow.com/thread-1824.html
Stop building: http://forum.tyflow.com/thread-1825.html

But so far it works fine, here I attached the video :
