Title: Colors in VFB
Post by: Pedro9374 on 2021-02-10, 17:51:10

Hello guys,

Maybe this a noob question but here it goes.

When i plug a photo on the Directly Visible Overide slot and setup a white environment, when i render the colors (specially the sky) are not the same. Is it possible to fix this? I have attached a printscreen

I do ask this because i like to use some photos as background in some renders. I know i can do that in PS but i really like to setup everything inside VFB

Thank you

What are your VFB Post settings? (the ones you are covering with the Render Setup dialog in your screenshot ;) )
Maybe you are using a LUT?

lol yes im covering by mistake :| i do have nothing turned on. Attached the image.  Maybe this has to do with the fact the photo is a jpeg?

You need to use Corona tonemap control node. https://coronarenderer.freshdesk.com/support/solutions/articles/5000522247-corona-tonemap-control-map
