Hi,

I have encountered a problem when I trying to build a fog solver by following the tutorial "Building Fluid Solver From Scratch" (https://www.sidefx.com/tutorials/masterclass-fluid-solvers-from-scratch/). My problem is:

I'm trying to implement the fog solver example shown in the tutorial. However, the anti-aliased noise seems not working properly, I could not see the fog effect from the scene view as the example shown.

I have attached the tutorial demo screenshot (named "it should be") and screenshots of my volume setting and volumeVOP connections within this post.

Could anyone help me with this? I'll appreciate it

Best regards,

Hi,

I finally found a way to make it work now. But one thing I didn't get that when I set the "Uniform Sampling Divs" to 75 as the tutorial did, the fog effect didn't show up, when scaling down the parameter to around 50 (or 60 maybe), the fog effect starting shows up incrementally, the lower the parameter is, the bigger volume the fog is.

Therefore, I just left the parameter to 10 (default parameter), to get the approximately fog effect as is shown in "it should be.jpg".

Did anyone know why would such a situation happen? I'll appreciate it

Best regards,
