Hi. I'm hoping someone can help tell me why a phoenix smoke simulation, using a tycache as an emitter, changes so abruptly between 2 frames.
I've also posted this on the Phoenix forums (and submitted a support ticket), as I'm not sure if it's a phoenix or tycache issue.
The change happens between frames 347 and 348 of the simulation (see attached screen grabs) which has run as expected up until this point (overall shot frames range is 55-428 ), but for some reason at this frame the smoke seems to stop being emitted correctly and a lot of the existing smoke seems to get culled too.
So far as I can tell the machine isn't running out of memory, as the size of the grid at this point is less that it has been earlier in the shot. The smoke is being emitted from a tycache object which seems to be behaving correctly, and it isn't getting clipped by other geo in the scene.
So far as I can tell there's no reason why this should happen. I'm stumped.
I've uploaded the max file and tycache etc to my gdrive here https://drive.google.com/drive/folde...usp=drive_link
This is a personal project so I can share any further data if needs be.
If anyone's able to take a look and enlighten me I would be eternally grateful.
