Hello everyone,

I am learning to make fire. I am trying to making it look really sharp and crispy. I gave value of 20 for “Sharpness” in pyro solver with values like 0.2 or 0.3 for “disturbance” , “shredding”, “confinement” and “turbulence” and the division size is 0.02, and still it doesn't look sharp. I am using Micropolygon rendering, with depth map shadows.

I have uploaded a video of my WIP render. I am still working on the shader.
Please help me if anyone has solution.

Joker has posted some amazing resources for fire simulation - it's probably worth checking the link and reading through it learn some cool advanced techniques

Really Thanks MartybNz

I checked your file advaitk8 ,To achieve better result you should care these points :

1. Increase your Turbulence and Swirl ,Because your Fire is so smooth

2. Improve your shader with above Topic's instructions to achieve sharpen result

3. for rendering Pyro effect I suggest you to use Raytracing instead of Micropoly ,In this case your fire will render with more details :wink:

Thanks a lot for the tip.

I will definitely improve my file by playing around more.

Hello Joker386,

I have a question. How do I make it move really fast like the actual fire in a fireplace.?

I added the velocity but it doesn't really look good. And I want to avoid using a timewarp to make faster. Timescale acts a bit weird too. Please let me know if there is any other way.

Thanks.

Just increase “Timescale” parameter in the “Pyro Solver” ! (in the Simulation TAB) 8)

Thanks.

I tried increasing the timescale. I was getting really step like simulation.
But then I had to increase the substeps and change the frame steps in Global Animation Options and now it works really good.

Thanks a lot.
