It is my first post here for an opinion. I used corona renderer but got a lot of noises around the image.
Need some advise from you guys to make my render better.
thanks,
Well, we will definitely need more info:
-how long did you render your images?
-what is your CPU?
-did you use default render settings (that’s recommended!)
You can find a general guide on dealing with noise here: https://coronarenderer.freshdesk.com/support/solutions/articles/5000501983
it is like 5 hous on pentium G4560 
budget system.
I kept almost all the settings on defaults.
I used HDRI and Corona sun outside and corona lights as seend on the ceililngs. I also used light portalson two windows to lower the noise.
Do you have any idea to make this iamges better. Design vise and tecnical.
thanks.
It’s not really the fastest CPU, but how long did the rendering take?
You can try:
-Enabling the New light solver option in the Performance tab
-Resetting the render settings in the Scene tab (render settings are really optimal by default, so there is no need to change them)
Other than that, I can only recommend allowing it to render longer.
