Nothing I do lets me render grass in Revit 2018

Hello!

I’ve been using Enscape for 3 years now and I was sure that I could make the grass render with my eyes closed. The project I am having trouble with is in Revit 2018 and there is seemingly nothing I can do to get the grass to show properly.

I have a request for a full render that was due yesterday.

Grass names are Tall Grass, Wild Grass and Grass and they are using the image provided in the grass tutorial

I have deleted and recreated the Toposurface. I can’t upload the model because it is too large. I’m sure the solution will be something very simple.

Can you post a screen shot of the grass in a 3D View and the material assignment?
