How can I make Megascan trees and plants and foliage emissive? #bioluminescence

[korteee118822 (korteee11)]

Hi,
I would like to make a similar magic forest with bioluminescent plants and trees. I would use one of the Quixel megascan tree pack, but I don’t know where to make the letters emissive. I tried some settings but it didn’t work. I was able to color the leaves with the health color settings in the material, but unfortunately they do not glow in the dark.

How can I make it emissive?

Hi korteee11,

You’ll actually have to edit one of the Material Functions to do that.

Open up “MF_TwoSided_Leaves” into the Material Editor and select the “SetMaterialAttributes” node - in the details panel, Add a new Attribute Set Type with the + icon and set it to EmissiveColor

Then double-click on the wire going into the “Base Color” to create a re-route node, and drag off that and add a “Multiply” Node. Then create a Scalar Parameter and call it “EmissiveColor” - that is what will control the amount of emission.

Now open the tree and find the material instance used for the leaves - click on the folder to browse to that MI and edit it in the Material Editor - you’ll find the “EmissiveAmount” parameter you added listed in the Details Panel, tick it and set it to something like 0.5

Now you should have something like:
