Hi Guys,
I have installed Corona 4 and when I render everything is fine, although if I use the interactive light mix the image is super blurred and I can’t do anything about it. It happens with new and previous files as well. I have tried every denoiser and haven’t changed any setting. The lighting is HDRI and corona lights.
Any suggestions?
Many thanks
Could you share a screengrab of the blurry results?
Hi!
That looks like a photo rather than screengrab though? We can’t tell what is blurry in IR versus what is blurry because it’s a photo - could you use print screen to capture the screen grab? Or even save the image from IR? Thanks!
Hi Tom,
due to urgency at work I had to downgrade to Corona 3 in order to get some work done. I will install it again asap and post a screengrab. By the way the image is totally blurred like the very beginning of the rendering and doesn’t get sharper.
Anyway I’ll reinstall Corona 4 and post the screenshot.
Many thanks

Hi Tom,
I’ve now noticed that no matter how big I resize the rendering window the resolution is very small (see attachment) and that is why is all blurred, looks like is zoomed in a lot, but the zoom ratio is (1:1)

Your resolution is tiny. Check if you have upscaling enabled. Go to render setup>system>system settings and see what’s the image upscale factor value - should be 1.0
Top man! It was 5 and don’t ask me why…
Thanks a lot!
