White gradient teinted glass

[fraggle]

Hello,
what approach is the best one to get a white gradient tinted glass?
Of course the fog will not work due to the way vray works using B&W color as mask.
Thanks for your feedback.

Do you have an example image of the effect you're trying to achieve?

like any gradient glass but with white instead of color (not frosted, but white inside the material)

I would propably go with either of the following ways:


For the first image: Blend material, blending between a white opque material (or a SSS one) and a clear glass
For the second image: Blend material, blending between a foggy glass and a clear glass


Just blend with a gradient ramp and you're good to go.

Edit: Playing with the fog bias value might get you somewhere, too, especially in the second example.

thanks,
I used the blend one from opaque to transparent but
that's really hard to simulate fog with a blend material.

The second solution won't work. White is not a fog color is equal to transparent.

2. Changing your fog color and fog multiplier will let you achieve this result

[fraggle]

This can't work on white because the multiplier need a color value to work and white doesn't have any color value.
Even with a white set to 254, it turn out grey/black immediately.

If you can fake it, use a [blend (blend (white LightMtl and Glass Shader)) and Glass Shader]

I don't think the second image has less transparent glass down there...I think it's just a result of it being thicker.

[fraggle]

true indeed, but I would like to apply this gradient to an even thickness and anyway it will not solve the white issue whatever the shape.
