Blender Flame Smoke animation rendering I am playing around with my first fire animation attempt.  Settings are done but I have the following 2 difficulties,


I would like the flame animation to be a constant one.  As it is it starts from nothing at frame 0, develops into a flame at frame 66 and stays constant till frame 100.
I would like it as in the part from frame 66 to 100.  I tried starting the animation at frame 66 but it did not work.

The flame is not rendering, only the smoke is.  I tried to enable the volumetrics as in the tutorial I saw but there is not enabling button. 




Here I uploaded the file I am working on.



Thanks for any help given.
To display the flame, connect the Volume Info/ Flame socket to the Blackbody intensity socket of your Principled Volume shader



As regards having a sustained flame, without the moment when it "ramps up", I believe the easiest way is to just bake your simulation cache for many frames, then remove the first 66 frames from the animation (Render > Start > 67). It's impossible to skip the baking of the phase where the flames develop, because you can't easily create an already-burning starting condition.

You could in principle move the smoke cache 66 frames forward, but it's hacky (requires moving several files manually) and I wouldn't suggest it.
