Alpha channel sounds good, but instead of using it for transparency effects (which are often slow), you can use it to change the specular (reflection) amount on the single material directly.

A quick mockup with the screenshots from above:

When you use the following reflection settings:

You can use the alpha channel like this in a custom shader:

There are many more similar possibilities, if you rather like to control the material by metalness and roughness you could do it like this for example:

Element 115 posted on October 20th, 2018

Working on one of a few train chassis setups for new custom coaster system. This will be the 4 - across seating version.

Looking nice there, Element.

I have a question for anyone who can help me. It's about the badges on the car bits for my Viper ride.

I'd like to change the light grey sections of the badge texture and have them as a chrome NL2mat i did up, like i've used around the edges. So the snake logo is in chrome, like the real ones.

Now, i have an idea to try involving adding a separate face using the chrome NL2mat slightly offset behind the logo texture plane, and modifying the image texture to use an alpha channel, so you can (hopefully) see the chrome NL2mat through it.
But i'm just wondering if there's a better, easier, more efficient way to do something like that.
