Hi Matt,
If you’re using the Paper 2D starter template, you’ll want to make sure that the camera in the character is not set to Orthographic. Currently not all light types are supported and there are known rendering issues with that view mode. You can change this in the Character’s BP by selecting the camera and selecting the camera then setting it from Orthographic view mode to Perspective.
Aside from that, check to make sure that your flipbook material is set to Lit and not Unlit, otherwise you’ll see lighting issues since it can’t be lit.
I checked this against 4.10.2 since I don’t readily have 4.9 installed at the moment.
If that’s not it, can you provide screenshots and settings being used for your flipbook material that can better help assess the issue.
Thank you!
Tim
