There was a puzzle where the outline was done, but the design of each individual part had not yet been decided. We had an idea for this part, but when we actually placed it on the screen, it was unexpectedly small, and it was a little difficult to distinguish the parts necessary to solve the puzzle.
So, to emphasize that part, we decided to make it brighter in the emission settings. However, when we try to make the emission color brighter by specifying HDR in Unity, the color specification is limited. Specifically, each value of RGB can only be specified as 100% or 0%, and intermediate colors cannot be specified.
Also, even if we try to specify a color other than HDR, it doesn’t shine as much as I would like. Therefore, I decided to test several patterns, such as blinking the material.
