"up-rezzed" fluid smoke quick test...

Recommended Posts

I found these all add up to nice results:

* Change the volume filter to sinc on your volume object.

* Higher frequencies on your emitter will exploit a higher res sim.

* Some kind of film LUT/sRGB LUT or just a gamma of 2.2 might help in a perceptual way, instead of looking at it in linear.

I did a test with the pyro res at 120 / 180 and it was still fast, but with a sphere emitter it didn't really give it much sharper edges :/

I have just used billowy smoke with noise and that works well.... It needs rest of course.

I enjoy Blackman myself:)

Nice test netvudu.

I like this tool but there is so much difference between a real hi-res sim and a hi-rezzed sim. It's useful of course, but it's not a replacement for a hi-res sim from my point of view. I'm sure you agree

Having said that, Sam.h: "higher frequencies on your emitter" do you mean in the AutoDop/Upres smoke solver??? like the manual advice on setting this to even a lower value (0.7 instead of 1). What's the real effect (I haven't had much time to try it out)?

Cheers

I would recommend working with the shader as much as you can, working with both sim and shader at the same time seems to work best for me now that I know a bit more about the process.

There are a lot of things you can do with the modifiers to tighten up the edges of your fluid. ( like on a density modifier, create a sharp falloff in the curve) I'm still trying to get the hang of all these modifiers, but I can see their strengths.

As well, you could go above 200 for your upres...try 280 or more. Good luck , Ive been getting some amazing results with these tools, just a matter of figuring out how they work. It's a much different process than maya fluids, but the results are coming out better too, ( I can finaly say goodbye to maya for good ;)

I meant higher frequency details in the emitter... so rather than emitting from an object you could emit from a volume and mult in some noise...

I would wholeheartedly agree with you if this was an SPH sim, but to my eyes for SDF sims this technique could be quite valid. Accepting it

Sounds to me like you are talking about the Pyro VEX Shader, while if you read above you will undoubtly realize I said I was using the billowy smoke shader for the up-rezzed fluid...

...you can upres more things than Pyro FX, you know ;)

But just make the test hi-res/hi-rezzed and you'll see a lot of difference. If you want a close shot, let's say these kind of commercials where everything is slow motion and close to camera... I think you cannot get along with this solution.

I wish I could test the hi-res, but today I don
