Bug in cylinder/fluid collision #3766

Open ad-daniel opened 3 years ago

ad-daniel commented 3 years ago

Describe the Bug There appears to be a bug in the collision between the edge of a cylinder within fluids, as can be seen from the video, instead of falling off directly, it seems to get stuck for a bit until the following shape pushes it off. No other shape appears to have issues like this.

It is not a regression.

Just as a (useful ?) note : when you change the "stream velocity" of the Fluid "FLOWING_WATER" from "3 0 0" to "1 0 0", this cylinder doesn't move at all anymore. Could this wrong behavior be somewhat related to the issue ?
