Some flowers material not showing up in matinee render

Some flowers material not showing up in matinee render. I tried turned off texture streaming… im out of ideas…

Are they SpeedTree or custom meshes or sample content from Epic?

From what i’ve heard more people are having this kind of problem and SpeedTree is aware of it but i still suggest reporting this to SpeedTree.

oh they are from speedtree.

oh… ok thank you.
