Is there any way to get correct photorealistic specular reflection from big sized Sun disk (Directional light with Source angle = 10.0) on the water made with new Ocean Water Actor and its built-in water material?

r.Water.SingleLayer.RTR 0 should fix it

Same issue in Ue5. Light is passing through objects and reflecting on water surfaces. Single layer water command didn’t help ☹

i think that the water plugin doesn’t support the sun angle variation for reflection size. (maybe water materials problem?) but we can istantly solve that issue by making (process volume - detail- reflection setting - screen reflection). then reflection is working… quailty is not lumen and rtx…
