Hi!

I've downloaded nice model from google warehouse to practice rendering.
The problem is- when I render with water smoothness 0 everything is ok ( obviously it looks like old school game

) But when i try to smooth water black triangles apears in reder image (like reversed faces) Any idea how to smooth water and render it in proper way?

Strongly smoothed lo-poly models and Indigo are not friendly. That's because you reach physically impossible incident angles above 90°, and in reaction Indigo terminates these rays with no reflection (black render)

You need to subdivide the mesh so that the waves are smoothly detailed. The excellent "Subdivide and Smooth" plugin from whaat would probably do the job, but it's non free.

Thanks for Your help! This plugin is not expensive, but I realy don't need it right now. I've tried to divide polys by hand, and it works, but it takes hell lot of time

And then there is always Blender. Export from Sketchup subdivide in Blender and import into
Sketchup or reference as an external mesh.
