View Full Version : i remember seeing this problem somewhere?
dosealas 12-17-2002, 10:03 AM hey guys and girls....
what the hell does this happen for....the two lights from the engines are volume lights and i put two light s in front o fthem so the ship could be illuminated from the engine glow....
when i decrease the muliplier i dont get this result but...i need to keep the multiplier high!!
any ideas?

I don't get your problem exactly, but I think you can achieve this effect without volume lighting.
maybe you could try some atmospheric like Fire, or use some plugins for this like firestorm (www.blur.com), or volumetrics like those produced by afterburn (www.digimation.com).
There is a tutorial written by Arild Wiro in www.3dstudio.com that will help you. Find it here (http://www.the3dstudio.com/(fbjncl45o0gcxe553mrux4zz)/tutorials.asp?id=74&mode=Display&name=Engine+Flames&ct=FX&author=Arild+Wiro&email=wiro%40secondreality%2Ech&url=www%2Esecondreality%2Ech)
Hope it helps pal.:thumbsup:

Also try just using particles and glowing the hell out of them.
Volumetrics need to be used sparingly. If you can get away with another method, best to do so as it increases your render times substantially.
Just making mention of this, as what you are doing is not wrong, but I would hate to have to work on your scene in a production enviroment. Not to mention, using a volume light won't allow for the engines to "trail". Just some thoughts.

dunno whay u need to drop the multiplier but heres a few useful suggestions
1) forget particles
2) if the multiplier needs to be lowered to avoid it lighting parts of the scene you dont want lit then exclude the geometry from the light
3) if you really do need to drop the multiplier value in the scene then simply drop it, then increase the volume lights fill % and if necessary brighten its colour
4) failing all of that, make a cylinder, map the transparency as a gradient inside falloff and give it some colour, falloff and wind up the self illumination
hope this helps

Ok, halo, why forget particles?
If he's animating the engines, mapping aint the easy way...And a volume light is'nt either.
Just curoius.
