Title: Gradually turns from opaque to transparent
Post by: Zvi on November 03, 2019, 02:27:19 PM
Is there glass material that gradually turns from opaque to transparent glass?

You'll have to use a gradient texture to control the opacity. Can't remember exactly what parameter you have to texture but it can be done.

Hello Zvi, ciao Nico.

I would use a glass material as base and apply a diffuse or slightly rough plastic as label on top.
The opacity from the label can be controlled by a fade texture like Nico mentioned right.


Hope that helps
Cheers
Marco

Nice execution of this look (and how to) here:

Thanks a lot, it's really helpful!

I tried, but  there was no gradient, as you can see in the attached image and ksp file.

Try this. It has a multi-material on it with two options. One with Eric's method (map the Diffuse and Specular Transmission channels with Color Gradient nodes) and the other with Marco's idea to use a label controlled by a gradient

Magnificent!
How do I turn the gradient so that the white is up and the transparent down? I tried to change the angle and it didn't work.

Reverse the positions of the black and white colors in the gradients and then adjust each one so that the transition occurs where you want it to.
