How to get colors inside a refractive object?

Recommended Posts

It's a shadowing issue.  The cube has a solid shadow, despite its transparent material.  If you stretch your sphere on Z so it sticks out far enough beyond the cube, you'll see it.

The cheap solution is to shut off shadow on the light (Shadow -> Shadow Type: "No Shadow"), or from the cube (note sure if that's doable in PBR Mantra).  The more expensive one would be to use caustics, but sloooow.  I'm still a noob on shading, so I don't know how you'd do caustics using Classic Shaders, but the Principled Shader has a "fake caustics" option.

H16 has some new features related to this. I haven't tried it myself, but there's a webinar about refraction, dispersion and nested dialectics here which should get you on the right track.

this could be a very noobish thing to do...but all I did was to lower the Opacity Scale of the cube..to say 0.5 and voila..

Wow guys, thank you for your answers!

I think the solution with the lower opacity will do the trick :)

The webinar looks also great <3
