Hi all,
I'm trying to figure out why I'm not seeing an effect of coordinate speed in my sims. Or maybe I am and it's subtle?
Fire Sims
I've attached a video of some RnD work I've been playing with. The first two sims have very different coordinate speeds (0.2, 0.8). The coordinate method is set to grid. The only thing I can think of is that my incandescence values are so high that it's limiting the visibility of the frequency. However with the other two sims, I have the method set to fixed and can perfectly see the frequency.
Since I'm fairly new to fluids, I don't think I quite understand the coordinate speed definition. Here's what the documentation reads:
Scales how fast coordinates are moved by Velocity when the Coordinate Method is Grid.
When Coordinate Speed is 1.0 the coordinates move through the volume at the same speed as the other properties (for example, Density). However this tends to result in the texture smearing out after a few steps.
Lower values tend to preserve the character of the texture and can look more natural.
Any help would be great!
Best,
Colby
