Hi~ Me again
I’m working on a GearVR demo.
The project can running on 59fps/s constantly under 1440P full resolution now,
But I was only using basecolor in all materials.
I read the GearVR manual that said Metallic,Roughness,Normal,Emissive are supported,
so I linked Roughness and Normal node to my Materials.(parameter node for Roughness;
normal map node for Normal)
As I expected, it didn’t work at all and fps droped a bit.
I switched to Android preview in my UE4, only basecolor showed too.
I’m pretty sure some of these effects need mobile HDR turned on - but beware this is a huge performance hit for mobile VR You will need to go through and turn everything not needed off and even then current gen phones would only support it for very small environments/projects
Some of those effects do work without mobile HDR however they behave very different and are much less pronounced
