Trouble Rendering Fire
How is fire rendered with Mental Ray? With Scanline rendering, it's pretty simple. Set up a gizmo, assign fire to it and adjust settings to taste. But Mental Ray will not render fire via a gizmo.
So how is fire rendered with Mental Ray?  Thanks a ton. |

Re: Trouble Rendering Fire
Deconstructing the Elements has Fire, Lava, Smoke, Water, Tornadoes, explosions - you name it.
I've only read through it, but I want to really work through all the exercises. |

Really??? DANG!  There HAS to be a way to render effects with MR. This just makes no sense at all. I haven't used scanline in over 4 years! ...And I'm not about to go back to it either. |

Re: Trouble Rendering Fire
SNAP! I got it to work!
At least, it'w working in an isolated scene - all by itself. I'll see what happens once I merge it into the scene where I couldn't get it to work before (with Daylight System active). I'm thinking that perhaps the MR Sky as an Environment Map might be what caused the fire effect not to work everytime I tried it before. If so, I'll just turn it off and go from there. |

Re: Trouble Rendering Fire
Hi Michael,
With a daylight system in the scene and exposure set up for it you will NOT be able to see the effect of your fire! Just as you wouldn't see any illumintion from a small hand torch if you shone its beam onto a patch of Bright sunlight!! regards Bri

I have only seen the original copy which used Max 6 and the scanline engine, not sure if any of the effects were updated for MR in the newer version!!  Regards Bri

The fire is in a fireplace within a room. The nearest window is about 25' away and buffered by a wall. No direct light is entering the scene. In fact, very little (if any) indirect light is entering this particular scene. therefore I could elliminate the daylight system without any impact on my scene. It was being used primarily for the room with the window that this space in adjoining. |

Re: Trouble Rendering Fire
I've disabled EC & the Environment Map (MR Physical Sky). Now all I get is a black flame. Even when I change the smoke color, the entire flame remains black.
