making fire

Dosser:
g'day all,

I'm wondering, is there an easy way to give the look of fire using just Anim8or? I know there's particle effects, which would obviously be the way to go for moving images, but I'm really just interested in a still picture.

The fire in the picture is intended to be very distant (a large torch viewed from far away, similar to a beacon or lighthouse).

I think I can do it fiddling with transmaps, but not too confident on this method.

Has anyone else done something similar and can give me advice?

floyd86:
Transmap can look good for thing like fire, and as you said, this fire is very distant. So using a transmap will probably come out good. Make a plane with a slight bump in it like this: ) this will give the flame a bit of depth. Then apply the material with the transmap on it.

Here's a quote from the old anim8or forums.  You just need to do some searching.

For those flames, I used a cylinder, and used the "Rotate Faces" tool a bunch of times. And, I also used my own material setting:

One Sided material
Amb: 0
Dif: 0
Spec: 1 (255,64,0)
Emissive: .250 (128,0,0)
Rough: 4
Bril: 0
Trans: 0

Then, I stuck a local light at the base of the object.

I tried that way, it's not a bad one: but his looks far better than mine. How does he get such a strong yellow touch to it? The material colours are all red, and the light can't have that much of an effect :S

Anyway, made a simple flame using that and some material fiddling (more yellow / orange colours, rather than just reds). Added a 'halo' (sphere of very transparent yellow). I'll render later, when the rest of the scene is done.

Thanks for your help.

Also, is there a bug with 2 sided textures and transparency? Transparency just doesn't seem to work for me once I tick the 'two sided materials' button.

hihosilver:
Transparency should work on both sides, but if you make one side transparent, and you see through to the back of a face with an opaque material on the back, that material will show through, but transparency should work on double sided materials. (though not using the ART renderer)
