Carrara - Octane water on surface Canundrum.

protovu

Hello Fellow Carrara Octaners,

So I have a snag I am hoping someone can help with:

Attached are two images. The actors we are concerned with here: the table top, and the water. The water is a metaball object, the table top a simple vertex object.

All materials(shaders)  are Octane.

What is happening is, any contact of the water drops with the surface result in the ink shown. The drops in space do not have this problem. The type of water drop object makes no difference (primitive or vertex).

To have the look I am after, I need the metaballs to be half way through the table top. Floating them over the surface doesn't quite cut it, though I am experimenting with having a negative metaball object push up against them to try to flatten out their bottom.

Ideas anyone? 

Thank you,

Rick

It's the intersection with the table that's throwing it out

The metaball modeller should have a Negative cube option,. which should be able to Flatten the bottom of the Positive spheres,. but,. unless you need those droplets to be animatable ,. I'd convert the metaball to vertex model,. then, select the bottom section,. Using the front or left view,. then scale that to almost flat.

Use Pathtracing or PMC  render option for best results.

Hi 3dage,

Thank you for responding.

Yes, animated. And, I have been experimenting with having a negative metaball cube push up on the underside of the water. The negative cube doesn't have very much power, so I have duplicated it many times, with limited results. I will duplicate it some more. Pathtracing and PMC............not familiar, will look into that.

Is there a reason my previously uploaded images are not showing?

Hey, 3dage. Thanks for the tip on the kernels. I would probably not have found that option on my own....right in front of my nose. Seems to help the liquid look a little. On flattening the bottom. I used the punch modifier. Seems to help.
