From testing this I suspect that it’s not supported for Mobile. I’ve emailed one of our engineers to confirm this. Sorry for the delay. 4.14 issues have taken priority as we’re getting closer to release.
Thanks for reply. Nice to see 4.14 is going well.
I suppose there isn’t anything that prevents it to be supported. Data is there ready for use and Mobile already support stationary directional light with static and cascaded shadow mapping is supported.
As I suspected, this feature is currently only set for Deferred only, so that knocks out mobile which uses forward rendering. One of the mobile rendering engineers is looking to see if it’s feasible for mobile. If I hear anything definitive back, I’ll post back here.
