Smoke

Post by B.Y.O.B. » Fri Nov 16, 2018 6:29 pm

A frame from a short smoke animation I'm currently rendering.
Render time around 7 min (including 15 sec denoising) for 100 samples.

Edit:
Complete animation: https://youtu.be/l_YPrGoFPzQ

This is a continuation of my older smoke test: viewtopic.php?f=2&t=358

lovely...

Way back I did some sims with realwflow and also fumefx and krakatoa. I remember that rendertime was always a fraction of the time the simulation took. Is this simulated inside blender?
I know there are some tools but since forever I always consider simulating fluids very slow and it scares me lol...

I'll upload the scene when I'm done rendering so you can look at the settings.

Yes, Blender smoke simulation, and in this case it's definitely the other way around. I think simulating took something like 15 minutes - then I rendered for a few hours until the noise and heat got on my nerves. I'll render the rest tomorrow.

btw You should consider to upload it as an official test scene.

Here it is: https://youtu.be/l_YPrGoFPzQ

The file is attached.
You first have to free the bake in the smoke domain settings, then bake, then you can render.
Note that I used a file output node and halt conditions, you might want to turn these off for your tests.
Also be careful about RAM consumption, rendering a frame takes about 4.2 GiB RAM and 2.5 GiB VRAM.
The baked smoke data takes about 8.6 GiB of hard drive space.

The denoised image has worked well.
