I am quite new to Photoview 360 (and rendering) and was trying out some random renders. However, on both preview and full render, the result came out grainy, especially on areas with lights.
I had a spotlight placed inside the orange cylinder on the ceiling shining downwards as per attached. The inside of the cylinder and the walls appears grainy. I have searched the forum and google for a solution, and have tried playing around with all the surface finish and illumination settings. However, the results in the final render turns out the same.
Hope you guys can help! Thanks in advance!
