vadsemir Posted November 16, 2014 Share Posted November 16, 2014 Hi guys, Would you please help me to figure out what is wrong with my material settings.... You can see that on the left hand the light is OK, meaning, the light passes through the kind of light bulb (basically sphere #1), and after that the light passes through just a round glass shape (sphere #2). But on the right hand i start getting a problem as soon as i add another glass sphere (sphere #3). Nothing is changed, i have only added 1 additional glass sphere. I utilize only 1 glass material, and even the depth of refl/refractions set to as much as 40 does not solve the problem.. Please advise! Link to comment Share on other sites More sharing options...
Corey Beaulieu Posted November 17, 2014 Share Posted November 17, 2014 What is your light setup? I get what you are expecting when I use both a Vray Sphere and a Light Material with Direct Light ticked on. All glass is shelled right? Link to comment Share on other sites More sharing options...

The light setup consists of just Dome light with HDRI map and the Vray mesh light in light bulb. In order to simulate the realistic light in this case i do not use any Vray Light Material. Yeah, i checked the glass shell, it`s ok, no normal inverted. Link to comment Share on other sites More sharing options...
vadsemir Posted November 17, 2014 Author Share Posted November 17, 2014 Actually i am trying to simulate the light not of the bulb itself, but of _spiral_ located inside the bulb, like it used to be some years ago. And on my first picture you can see it is ok (on the left) but it is not ok (on the right) as soon as i start to add another glass sphere cover.

jasonstewart Posted November 18, 2014 Share Posted November 18, 2014 Refraction Max Depth? At the top of the bulb there seems to be some additional glass that is black as well, worth a shot. Link to comment Share on other sites More sharing options...
zuwinnadi Posted November 18, 2014 Share Posted November 18, 2014 Might be worth checking your general reflection/ refraction limit in your scene: Rendersetup /V-Ray / Global swithces Link to comment Share on other sites More sharing options...
vadsemir Posted November 18, 2014 Author Share Posted November 18, 2014 I have simplified the scene which means i have deleted all the details that might confuse anyone. The only stuff left is - glass spheres, the glass bulb and a light source, just simple Vray Light. Again, despite the fact that refl/refr. settings are ticked on and extremely leveled up, i get not what is expected - when the large sphere is added (by copying and scaling), the light seems not to get through,which is not physically accurate, since the glass material is transparent.

Ismael Posted November 19, 2014 Share Posted November 19, 2014 :eek:Affect All channels in refraction? Does glass have thickness? Link to comment Share on other sites More sharing options...

The glass sure has some thickness, as you can see on the screenshot, as well as the result of making Refraction affect all channels Link to comment Share on other sites More sharing options...
