Luoshuang's GPULightmass

[anonymous_user_21e38222]

Could someone tell me, what I’m doing wrong? I have a single scene with an interior and exterior, mostly with Datasmith geometry and shaders, and textures resized by hand between 512-1024px res. At some point, the light build stopped even through the console. At the moment I have around 220 items in the scene for which you need to build a light. During the calculation of bounces, the memory of my GTX 1060 is loaded at about 4.9-5.2gb out of 6, but after last bounce pass, I’ve always get that “out of memory” error. Hom many VRAM do I need more for the next step? Or this is impossible to get away from that, for now? I’m using gpu lightmass for UE 4.20.3

For GPUs with low VRAM amounts, try to keep your lightmap resolutions to 512 and lower.
