Title: Unwanted opacity on objects with Environment Override
Post by: farid on 2019-12-10, 20:04:20

Hey guys,

I wonder if anyone can help. I am using Corona 4 and have stumbled upon the following issue: When using Environment Override the objects become transparent. Please see screenshot attached.

Hi there, Can you try this with the latest version V5? It's free to upgrade. https://corona-renderer.com/download If it persists, can you please send us the scene via our private uploader?

If you used background image with screen mapping for reflection override, then it's "correct" result. You should always use image with spherical mapping for reflection override. It's not a problem with V4 or V5 and not even with Corona, other renderers will give you the same result. You give the wrong input and renderer will spit the wrong output.
