I started to work with my Version of TFD.

Here in these Files i have a Torch and started to set it up.
The only Problem ist that the Density of the Temerature is being cutted out. I dont know what i have done Wrong.
For the Density there is more than enough room.

Just try it out.

You have not activated density in the main settings .You are not emitting density or fuel. density creates density straight away fuel can be set to create density when it burns. You are using temperature to map the density but 1. the smoke colour is too dark 2. The cooling means the density since it is based on temperature will fade out too soon, if you lower the temp decay the smoke will last longer but the flame will also last longer. You are far better dealing with smoke as density. Your file is R17 and I have r20 so I will not be able to give you a file

Just add 1 to the density emitter and shade density with density and make sure it is active in the main settings

I finaly made a pretty good render this time.
A simple Torch.

The only problem was the extreme rendertime. But if i go up with the Voxel Size the fire is blury.
From 0 to 750 i had a rendertime of 18 h.

I hope you can give me some hints how i can reduce the enormous rendertime.
The Cinema File and he rendered animation are here.

As far as i figuret out, the tfd is beaming lightinformation himself.

How can i adjust the light that been rendered by the Container himself ?

This is how far i am come.

I am not able to adjust the Light, that comes out of the Turbulance Container himself. I allready tried a few settings but the lightstrenght is allways the same. I cannot adjust it.

Here is my actual work.

I tried to render a test. The basic shadow that is thrown along the Wall if blurry and false.

There is the last character, an "_" missing on that link.

Anyway, TFD creates great global illumination of fires inside rooms. Just turn of the "default light" in the render options, use GI, and add an additional light source with shadow enabled to have more control over shadow patterns on the wall.
