Hi,
I am currently struggling to achieve something very basic with PhoenixFD. A simple colored fire like on this example:
I assumed something like this would be very easy, but so far I have no luck fighting the user interface. I assumed that fire appearence/color settings reside in the Volumetric options window, and that's where I went. By default, fire color seems to be derived by Kelvin temperature gradient, so as soon as I found out I can not edit colors in the gradient, I logically went to the based on dropdown and found two options: Texture and RGB, which I assumed would help me achieve what I want.
Upon selecting RGB option, Color and Intensity frame in the UI became inactive, but no Color swatch to input fire color has appeared. I therefore opened PhoenixFD documentation in search of where I should set up fire color, but documentation is very lacking in explaining how "based on" modes other than "Temperature" are used. When I just try to render the fire, it disappears, and does nothing. I proceeded to switch to Texture mode, and plugging Gradient ramp texture inside of the Texture slot, with a weird feeling that I have no idea in what way the texture would actually be mapped on the fire - would it be the same way like temperature mode, derived from gradient? Or is it some UVW space of the grid?. I tried to render, but again, nothing rendered. I tried changing RGB level value of the gradient ramp map to extreme values like 1000, but smoke still did not render. Checking "Modulate" option did not do anything either.
So, I would be thankful for any guide on how to change fire color, and I would also suggest updating documentation so that something so trivial is not so difficult to figure out.
Thanks in advance
