This may be an odd question, and probably past the capability of the Mental Ray renderer in Autocad, but anyone have an idea on how to do Fire? I have a fireplace I need to add a little pizazz to.

print it out and put your fireplace next to a real fireplace.

 

...but seriously, one of our rendering gurus will be along shortly.

In Max you can create fire using a particle system, But in Autocad? I don't think it's possible.

 

The best thing to do is just add it post-render in Photoshop. For the rendering, you could place a low intensity reddish orange light in the fireplace to produce the glow from the flames, and then add the actual flames in post.

That is what I was afraid of.

 

Ohh well.

It can be done in AutoCad. Here's how: Use the first image in the texture slot, and the second image in the opacity slot. Create a couple of surfaces about 24"x24" or so. (Make sure your material's tile size is 24"x24" as well.) Place the surfaces at various elevations and various depthswithin the fireplace. Now, place a couple of point lights "in the fire". Change the resulting color of the light to a fire-like hue and the intensity of the lights to around .05. Under Attenuation, change "use limits" to yes, and the end limit offset to around 6'. Under rendered shadow details, change the type to soft (shadow map), map size to whatever you want (I used 256 for this one) and softness to 10. Attached is the result I got using those settings. Please excuse the low quality. Hope this helps.
