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?
-
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.
-
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)

in a 2-sided material, the transparency settings for the front and the back are independant of each other, so you have to enter values for both. when you turn on double-sidedness, anim8or doesn't make the back values the same as the front, it sets them all to the default new-material values.

Yeah, I set both sides to .01 (should be an practically transparent) transparency, and it was still a solid sphere. Untick 'two sided textures' and it disappears.
