Hi Everyone,
My first post here. I have job that I am doing for a client with A LOT of trees. As the rendering is fairly loose the client has requested that the trees crowns be transparent so they do not block too much of the building. Normally I woudl apply a fresnal Fallof map with gradient materials to give the edges of the transparent trees some definition, but I am at a loss as to how I can achive this in Vray. I've tried using a fallof material in the diffuse chanel of a VrayMat and setting the refract to white, but the effect is nothing like what I want. I was able to throw a VrayWrapper around the standard material I described above, but it is brutally slow to render.
Is there a way to do this?
THanks,
jeff
