Emissive tree material - and Quill shader mixed
Happy accident when creating an emissive material for the tree trunk created in Quill. I applied the Quill Vertex shader to the leaves and experimented with changing the leaves to the emissive material. Clearly had missed most of the frames apart from two. Created an interesting strobe effect, which is something I was hoping to create, to replicate David's wayfinding of touch and objects appearing from negative space
