Vray-Water shader

#1

Hi
Im making an animation of a can covered with water drops.
Its almost done, so I made a low quality render to test it out, and everything looks ok, except the water drops.
At some frames they are ok, transparent and everything, but in others they look like asolid piece of something.

 This is the shader:

 And this is the scene setup:

I guess Im making some mistakes about ligthing, Im not an expert of it :frowning:

Can someone help me out?

You have grey background covering the entire thing. Of course your water would reflect it. You’ll want some darker area so your water can have parts not reflecting anything and see through a lil better. Lower your reflection glossiness to something like 0.98 would help giving it some high lights as well.

You should place your light cards yourself to mimic studio set up in this case. You can look at, or try, some of the studio HDR to get you started.

BTW I just noticed the mesh in maya displays in a strange way
Half of the model is black: http://prntscr.com/a2dgkg
And the other half is normal: http://prntscr.com/a2dhbm

In the two pics I just rotated the mesh, from the same camera angle.

Do a AO/Dirt pass if you want to check your model. Maya viewport does not display V-ray material that well.
