I'm having trouble using this operator for collisions, I attached an example.

hi, c53.
Just enable 'Invert' option in your sphSDFColl operator and it should work.

Thanks for the reply Skinnytorus, enabling invert does produce collisions but it also has some strange effects. I don't think that the operator is working correctly. I tried to use the most recent wz4player(v0.210) to play magellan and in one of the scenes the liquid falls through the mountain mesh instead of colliding. The samples in example.wz4 where the operator is used don't work well for me either.

Then it might be a version issue. FR have changed a lot in WZ4 (and maybe the player) since they published Magellan.
Try asking ryg about it at http://www.pouet.net/topic.php?which=8736&page=25

I fixed it in CE, collisions are now working with this operator

Respect, man. Congrats.
