In 4.14, I have encountered translucent flickering with the forward renderer in translucent materials that have refraction or use a scene color node. I have also found valid workarounds by changing r.SceneColorFormat to 4 (we normally use 2) or set r.ParallelTranslucency to 0 (which is normally set to 1). Performance is everything since we’re doing a VR project, so I’ve been trying to avoid using such materials so I don’t need to switch these values…
