Ok, I was hoping someone could shed some light on my lighting and rendering quandries when it comes to this wanna be photorealistic gatorade bottle. While the modeling isn't all done and everything I started trying to work on the traditional lime green liquid for it. Well at first I tried an actual object inside the bottle but my old teacher said just to use a volume effect on the bottle.

I am just not apt enough to get this to work as you can see, my lime green liquid looks very very purple.

Any suggestions?

I'd say that your ray depth needs to be turned up, but I don't think that is the problem. I just did a bottle (cola) the other day. It had to be whipped out really quickly. (Short deadline.) So I just used a duplicate of the bottle, shrunk it, cut the top off and made it a brown color. Then I associated an extra light to the "liquid" and used it to get the right look.

Hm, so you did what I was thinking of doing the first time. Let me get this straight, you made the light on the "liquid" only associated with that model, and excluded that light from the other models?

I'll try that tonight, thanks Ed :)

Duplicate objects are probaly easier, or even an inner to contain your volume, you may be having problems with colour due to the volume effect absorbing colour, so you need to use the inverse of what you want.

You may also want to pipe a different shader to your shadow.

Good luck,

I'll keep plugging away at it. Sometimes I feel like I know what I'm doing and other times I just feel way outta the loop. I really hope to overcome that soon :)

Yes, that is what I did. It makes it much easier to control the color of the liquid.

I still obviously am missing something since I did that but I couldn't get my colors right. Was the light inside the "liquid" perhaps? Mine wasn't and I hadn't tried that so I was wondering if that was what you did.

Thanks Ed,

The light was outside the liquid. I also adjusted the color of the light to help "push" the color of the liquid into the right range. Brown in my case. Try turning the intensity of the light up till it looks good. (I think I had mine set to 3 or 4.)

AHHH, 3 to 4 on the light, hehe tricky Ed tricky :)

I'll go ahead and try that tonight. Thanks as always.
