How can I make my plants change material to an emmisive one in the night so that it is “Bioluminescent”.
If you ever saw James Cameron Avatar you know what I mean.
Thank you
It depends on how you are switching between day and night. But the basics on how to accomplish the switch are pretty simple, theres two methods i can think of off hand. First you can use the set material node which will give you an instant change to the new material like flicking a switch. Second and this is the method i would use is to multiply the emmissive value by a scalar parameter in your material and set the scalar prameter from inside your blueprint using a set material scalar parameter node. This method allows you to change the emmissive over time if you wished through the use of a timeline which would create a more natural look.
