Hello UE4 community,
to understand certain methods of using nodes and calculations in the Material Editor, can you preview the calculated number, like you can see the texture changes on every node?
For example, in one tutorial I saw, the instructor recommended to use the Red Channel of the Albedo Map and Multiply it with a Scalar Parameter and putting this into Specular.
Because Unreal need a number between 0-1 for Specular, I would love to know, what number will be there after this method or also in between to check the path and understand everything even better.
Thank you, greetings Frederick
