Parallax Occlusion materials have some issues with the forward shading option; It generally works, but it then has some “greasy” artifacts on the materials in the level.

Hi ,
Forward rendering in 4.13 is super
early, only the first checkin of many
really, and not ready for general use.
That’s why it’s not being announced in
this release. I expect it will be
ready for use in 4.14.The only things working in 4.13 are
the actual forward rendering of
multiple lights, with dynamic shadows
from stationary lights on opaque. No
MSAA (which is the whole point of
forward), no significant performance
gains, no blended reflection captures,
no shadow receiving on translucency or
even support for translucency lighting
modes.
Once this moves towards 4.14’s release and is an announced feature we can start adding tickets for issues like this if they are still occurring. Until then it’s still heavily in development and is not expected to work correctly in all instances.
Thank you!
Tim
