Need help with solving a glitch when rendering water

Post by rotex » Thu Feb 16, 2023 7:17 am

Hello all renderers!

I've had an issue with my renderings of water for a specific model (see attached picture). I have tried to adjust and change different settings but without luck. My concern is the shadow ring along the perimeter where water meets the bubble shaped dome, it's very unrealistic and I would rather get rid of it.

Hopefully someone can help me.
Thanks in advance!

choose water material with Twilight Material editor and disable "cast shadows" and render with Easy 08 render setting.

Easy 09 or 10 are fully unbiased and will ignore the cast shadows setting.

Easy 08 is for outdoor rendering with unbiased quality but will allow not casting shadows for objects and allows fake emitters.

you can use this water.
It's the template "Liquid>Water" with a procedural in the bump and color white.
Advanced>Cast Shadow is disabled.
see attached .skp scene
Rendered on Easy 08
