I need to add color effect to spatial and be able to remove it conveniently. For example, suppose that mage casts ice spell on other character. I need to visualize the cold debuff by making it bit more blue. After cold debuff is over, spatial has to look normal again. If character is poisnoned, I want it to turn green and make it look normal when poison debuff is over.
Problem is that I don’t know where to start. Should I do something in control’s controlRender-method or change material somehow?
I’ve already read documentation about Post-Processor Filters and Effects, Materials, Shaders and Shader Nodes.
I’m not entirely sure at this point if I wan’t to be able to combine these color effects or not. If it doesn’t cause too much trouble, I’d like to keep that option open.
