"Foliage" Master Material - Mage Hideout

This is the master material used for the plants.
Because I needed to create several flowers color variations I decided to multiply different colors on top a neutral flower texture.
I also wanted to make the plants flowers glow: the glow animation pattern is varied through a channel packed "Cloud texture".
The channel packed "RMA texture" used by this material is slightly different: it holds a Roughness map in the Red channel (used as Cavity to "neutralize"/"tone down" the light in Unreal) and an Ambient Occlusion map in the Blue channel (used to add some shading to the plant leaves). Specular and Metallic are set through parameters.
The RMA texture was the first iterations of my channel packed textures. I changed to SRM because I realized that was better to "neutralize"/"tone down" the light with a Specular map, instead of adding darkness with an Ambient Occlusion map.
