Hello,
I use the sphere refraction model (the only one working for my case), to simulate water surface.
I get quite good results but something is bothering me :
- refraction index must be really low to get something render through surface (not realistic but ok, not a big problem)
- with a correct index I get “reflection” artifacts behind the refracted object (mush more bothering. It’s appears like a rendering bug)
See on simplified example :
