I saw a post where the poster was wandering how to do a spilled liquid after
failing with blobs.. So I've knocked up this test scene using a couple of
splines for the liquid which might help them.
I'd like to invite suggestions for improving the lighting and look of the
water, or better still change it from water to semi tranparent coffee. I'd
like to get this simple scene improooooved ( that is to say realistic ).
Thanks
Heres the code if you want to have a stab at it...

Some suggestions:
- Usually, materials and especially wood tend to be darker where wet.
- you could improve your wood texture, with better pigment and some normals.
- it would be easier to see where there's water with a clearer
background to be reflected in it.
Efficient how you did the water patch,

Id suggest some media, perhaps a photon map just for cool effect,
darkening the liquid, even if it is water, and increase the ior.
That about sums it up, looks good so far!
