Flip Normal map green channel

I would like to flip the green channel of all the normal maps plugged into a material instances. I’m using a Master Materials and Material Instance.

Is there a way of using a “-1 scalar” or a “One Minus” to flip the normal map green channel in the Master Material so all the instances will flip the green channel?

use a “*-1” as they go between -1 and 1

I guess you can copy the texture and make a flipped version

or as @RecourseDesign says

Thank you RecourseDesign and ClockworkOcean. This helps me a great deal!!!

Just out of curiosity, would this “Flip Green” be acceptable, too?
And would this be ok to add a Multiplier to the Normal Map to control the Height?

It has to be a -1*

Use FlattenNormal to control the height. Normal maps don’t work like texture, hence lots of special nodes.

Like this?

Perfect :slight_smile:

Thank you so much!

For controlling the height of the window, use FlattenNormal. The reason there are so many special nodes is because normal maps do not work like textures.

The perfect solution.

I don’t think there is a better solution than this.

Use FlattenNormal in order to build a window of a specific height. Using normal maps does not produce the same result as using textures, which is why there are so many special nodes.

It’s the perfect solution you’ve been looking for.

This is a perfect solution for all your needs.
