Multiple Mesh Emitters Grain

[snaap]

Hi there. Please accept my apologizes if its a repost. I m new around here. Here is my problem. I ve created a night forest scene with moonlight from side which is basically a octane daylight colors adjusted. I have 10-15 lanterns with flickering (with vibrate tag) mesh emitters (spheres) inside and octane material/blackbody emission active with 2000. samples each. In kernel settings i have directlighing with 512 samples specular depth of 3 glossy 1 Diffuse 2 ptpower 0.01. Now when i rendered scene (in res. like 4000x1000) the trees that get light from emitters are extremely grainy. I have approx 4 minutes render time for each frame. So is there a way -ways to enhance result without crazy render times ? Any help ll be appreciated. Thanks.

++ when i use only daylight, that gives me nice result even in dl sampling 128.

Hi,

500 samples is probably too low for a dark\night scene. try bumping it up a bit.adaptive sampling can really help with hi sample render times. also, the lower the geometry on mesh emitters the less noise u get...try optimizing ur lanterns geometry.

HTH,
