Blender 2.65 Fire problems

I’ve been using the smoke simulator for about a year now, but in the new options i cannot manage to get the materials to look like realistic fire as well as the renders come out very pixelated despite a very high resolution. Any hints?

The pixelation will probably be fixed by decreasing the Step Size under Step Calcuation under the Integration section that appears under the Material panel for the domain object. I think it defaults to 0.2. I use values around 0.005. It made a world of difference. Might depend on domain size etc, so experiment a bit.

As for the fire material, study the materials in the blend files posted here:

The materials are brilliant and I think possibly by the genius behind much of the smoke and fire simulation code.

It’s helpful. Thanks.

The step calculation was what had me baffled. Extremely useful and actually improved baking time!
