Hey guys,
This is my first post here! I'm new to Houdini and learning a lot from the shelf tools, available tutorials, forum posts and documentation.
Now I'd like to create dust trails from shattered asteroid pieces. Here is what my trail setup looks like so far (.hip attached):
I'm almost happy but a few things should be improved/fixed:
The "Source Volume" node doesn't know the torus' velocity when drawing into the density field, which results in stepping.
I'd like the smoke to interact with (flow around) the geometry. Can I draw it into an obstacle and/or velocity field? Merging the solvers didn't help yet.
Maybe I could modify the air pressure/resistance aroudn the asteroid and ignore it for the smoke that's far enough away?
With the "Gas Resize Fluid Dynamic" node active, there's some strange aliasing happening towards the end.
Any tips on how to achieve/fix those issues would be great! I've been searching the forums and several tutorials already. But as today most of them are not written text but videos instead, it's hard or at least very time-consuming to find specific information.
I'll keep playing with nodes and parameters, watching volume wrangling tutorials and also try preparing an upres setup.
Thanks!
Hebi
