Thanks!
Very cool Steve. Great looking fire! Thanks for that tutorial.
hi Steve, great tutorial, thanks, an excellent result, I'm using your node setup to create flames for a movie - I don't think you mentioned anything about your values for properties > geometry > volume sampling > step size and max steps - these have a huge impact on the final result - defaults are step size 0.1 and max steps 1024 - are those the values you used? - best, Stephen Norrington
I believe I left those settings on default, I did some experimenting, and when using de-noisier the results where so close that it didn't warrant the extra rendering time you get changing those settings.
thanks, good to know - another question: do the overall dimensions of the domain and/or its scale (applied or unapplied) affect the resolution of the sim or are domain divisions a standalone grid that gets subdivided the same amount irrespective of the size of the domain - in other words, are domain division sizes determined by domain size or are they independent and "outside" the sim with the domain "overlaid" on them - I'm having a hard time getting blockiness out of my sims even though I'm working at 128 domain divisions, no matter whether I use a tiny domain or a huge one, not sure why - SN
