CineCamera focal length changes material when rendering.

I’m doing some nice renders but when I change the “Current Focal Length” to something higher than 35 and pull the camera back to fit everything in shot, the hair renders incorrectly. If I have a higher focal length and put the camera up close, it renders fine.

I though it might be LOD’s since the issue seems distance based but everything is forced to LOD0

any help is appreciated, thanks!

I think I fixed it. had to change the “Opacity Mask Clip Value” to 1. I guess since the camera is further back this needs to be higher
