Hello, I am using Houdini 18.5 with the pyro sparse solver and simulating plane trails moving from point a to b. When simulating first 100 frames it goes quite fast.. max 1 minute per frame but for the next 100 frames simtime is now almost 15 minutes per frame and I am only talking about 1 trail. Multiple will be added soon. Problem is I actually don't need to simulate the areas where the camera does not see the trail. After 100 frames, over 50% of the trail is not even in the camera frustrum anymore. I was wondering if I can use some kind of dynamic bounds with the camera frustum. I only want it to process the data when seen by the camera. If the trail moves out of the camera frustrum it does not need to be simulated anymore. Not removing it after the simulation but while the simulation is necessairy to improve the speed. Any hints?

Motion Path and Camera handles visible simeltenously
demoan666 posted a topic in Animation & Rigging
Hi everyone, I am trying to get to see the camera handles and motion path at the same time, unfortunately seems i can not do it, this is very helpful while animating the camera however it seems i am doing somrthing wrong in this regard here is what i mean exactly: please see attachment grab01.mkv in addition to that a few more "whys": 1. why the motion path doesnt show first and last keyframe's tangents 2. why the camera frustrum handle moves to the "not visible" motion path @1:19 mark on the attached srenngrab 3. why do i have an alleged "orphan keyframe" on the motion path on frame "49" while there is no keyframe on that frame PS: that being said i must admit i do not understand the hudini handles' full potential yet, still studying it. I hope someone magical has the answers/ solutions thanks in advance!
