UE4 not support forward rendering so i can not archive that m i correct ? If so. Can anyone tell me when this feature will be support ? This feature only in the wish list and i have feeling that UE4 is willing to sacrify forward rendering to make the engine less complicated . Mobile is my battle field not console .So i need an offical answer so that i can decide to move to Unity or wait (when)
Hello LamVu,
This feature has been implemented soon. This will be a huge change for mobile developers.
Rest assured that this issue has been addressed and will soon be available for development.
Thanks,
thanks for your answers . UE4.9 will support dynamic point light so i guess spot light and the rest will coming soon . By the way . UE4 use deferred rendering for all light right ? . Is it impact FPS on mobile ?
Hey Lam Vu,
Yes, UE4 does utilized deferred rendering for all lights with a few exceptions.
1.) For mobile development, for devices ES2 and lower, UE4 still uses forward rendering due to buffer limitations.
2.) For dynamic lighting on devices that came after ES2 that incorporated metal shaders and required greater performance then the render method switched to deferred. There are still limitations due to the amount of buffers that can be assigned before frames per second drop below 10. The code is there if you want to utilize more buffers if you want to.
