great!!!

I like it. Is it possible for you to share some details on your environment/material. This is something I have had trouble with. I’ve gotten close, but not quite to the level of that render.

skylight; white multiplier 0.3
background; black
+
i used a cylinder as circle light with an emissive layer multiplier set as 8

Glass material; Reflection layer, reflection set to white with a fresnel map
                       Diffuse layer, transparency set to white
                       Refraction layer, refraction white transparency black IOR:1.6 my Fog color is RGB 118,87,209 fog multiplier 0.1

I hope these settings will help you. if you want any further settings i can send you a “configuration” file.

Thanks a lot. I will try some of these settings and see what happens. Thanks again.

this one has a rough surface and i put some air gaps into the glass

… and now set the color mapping to gamma 2.2. :wink:

thanks Micha.
I tried it but it lost its ambience, it become too bright and looked not good to me.
is there a special thing about this gamma value (2.2)?
i am asking that because i dont know anything about it? :sweat_smile:

Best you read here:

and here

Vray calculate the lighting in a linear color space, but if you like to use images on a computer screen, you need gamma ~2.2. So you must set the output to gamma 2.2. Than you get right fresnel reflections, light and shadows. Problem: if you use textures, most this textures are corrected for gamma 2.2. If you set the output at g2.2, than your textures are corrected twice. So you must set all textures to 1/2.2=0.45. The same problem with colors, but here we have no option.
I hope the next SR solve this workflow problem. I count the days to get a global gamma control for colors and textures. :!:

Back to your image: if you like to get a natural lighting, you must set gamma 2.2 and adjust the intensity of your lights and colors. Best you set g2.2 and the ground at white. Than you adjust the brightness of the light, so that the white ground is right. Than adjust all other colors.
