Would anyone be able to tell me what that noise (from the light inside the temple) is from? I had “Denoise Data” selected… This was rendered in Cycles with a GPU. Not sure what’s making it so noisy… but here’s my super basic temple.

I am not sure, but “denoise data” selected is probably adding more info from the render to the post-processing function of Blender, which you are not using.
Noise comes from too low light (add more lamps, no night scene) and low Cycles render samples (lightrays). How higher the samples, the lower the noise. But huge increment of render times.
So Switch on desnoising at low samples.
I’ll try that next time. Cheers!
