3ds Max Mental Ray : Bathtub water reflection light onto walls

[yourfather]

Hello everyone.

 

1. I have bathroom with large windows that lets the sun in. I want the water in the bathtub to reflect the sunlight onto the surrounding walls.

 

2. I am using the standard AutoDesk Water material.

 

3. I am using Mental Rays Daylight System

 

The problem is, I dont get any light reflecting off the waters surface onto the walls.

Any tips would be greatly appreciated.

 

Best,

 

Robert.

You have to on 'caustics'. Here is a great tutorial for that.

Hey guys, thanks for replying.

 

Though I already understand how to get basic caustic lighting.

 

There's a few things in my scene that might make "caustics" or light reflections on the ceiling a and walls impossible.

1. I'm using a daylight system. So maybe the daylight system won't generate caustics?

2. Maybe the walls are too far away from the pool of water?

 

Can any of those factors be contributing to the fact that I can't get caustic light reflections on the walls and ceiling?

 

Please bare with me as I am Farley new.

 

Best,

 

Robert

Best thing is, if you are happy with your overall light settings just keep it as it is.

For caustics, make a new light which affects Caustics only. Normally I’m using this method. That makes easy to control it.
