So I’m strugglin’ to reduce noises of this image:
I stopped rendering after the right half is finished. I can still see noises at around the upper right corner.
I have tried a lot of tech to reduce noises. I increased the size of that point light to 1 cm, used filter glossy of 0.5, added a light portal at the light bulb, facing to the floor, also selected the “limited global illumination”. The sample is as high as 20480. So I wonder if I’m missing anything? Or what is the regular sample I need to render an interior image like this?
Note: There is a light bulb with a point light in the middle as you can obviously see, and there are also 3 other same light bulbs without light. The light bulb use the glass+transparent mixed shaders. Everything else is just the chair model.
I appreciate your help!
