PhiiLL Posted June 7, 2017 Share Posted June 7, 2017 Hey Guys, I'm trying to achieve the look of an object inside glass. My problem is, that the inner object has no color when I render it. Could you please help me? Thanks Sphere_In_Refractive_Cube.hipnc Quote Link to comment Share on other sites More sharing options...
jimmay Posted June 8, 2017 Share Posted June 8, 2017 (edited) 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.

rich_lord Posted June 8, 2017 Share Posted June 8, 2017 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.

Noobini Posted June 8, 2017 Share Posted June 8, 2017 (edited) 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.. Edited June 8, 2017 by Noobini Quote Link to comment Share on other sites More sharing options...
PhiiLL Posted June 10, 2017 Author Share Posted June 10, 2017 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 Quote Link to comment Share on other sites More sharing options...
