Purple background?
Hi everyone,
I'm working on just updating a few lens I created last year and the preview shows this strange purple background. I thought it was just my laptop, but it's showing up in the lens. Any ideas on how to fix it? Maybe I should just redo the whole thing...also, any tips on making the lens fit the whole screen? It was full screen last year, but I can't find the right dimensions for every screen size. THANK YOU!

It means the textures/Images are missing or are not connected anymore.
in my opinion it looks like your color correction is missing
and your particles. just the textures in general
