In my game Atmocity, buildings have an efficiency variable that determines stuff like population capacity, resource output etc. I would like to somehow make a visualization mode so that players can easily find areas that are underperforming.
Essentially what I would like to accomplish is to lerp from this:
Since my knowledge of shaders and image effects is pretty limited I’m open to ideas on how to do this in a performant way. I have to keep using the standard shader and don’t want to switch materials, since we’re talking about potentially hundreds or thousands of buildings.
How did you solve this problem? Screen space and mapping world pos of the point to the correct building/parcel? Or any other approach? Thank you so much!
A replacement shader replaces the standard shader. The replacement shader is pretty much just a gradient with shadows and lighting turned off.
Buildings can inhabit the same space (building origin is in the center of a 1x1x1 space, so several buildings can have the same location). Because of this I pass the building’s efficiency variable via a material property block to the shader instead of using world pos. This 0-1 variable is then interpreted as a red to green color that is added on top of the gradient.
I will be doing a short tutorial on this fairly soon.
