slow render query

Hi all,

Im using the render selected feature in corona. I’ve got a simple white screen object selected and it’s working great. However the time for rendering seems to be far too high.
full animation will be 180 frames and some are taking 7/8 minutes just to render.

Are all the lights etc calculated using this method, is that why the times are high?

I have noise level limit set to 20% and no denoising on.
resolution is 1920 x 1080 @72dpi

C4D R19 / latest version of corona

As far as I’m aware, yes. Your only telling Corona what objects to render based on how your scene is lit. I would remove all geometry and lights, keeping the screen only.
