Eevee render - Mauve

if I use EEVEE in lookdev I can see all the mat well
but as soon as I try in rendered mode the scene becomes all mauve!

how to correct that ?

happy cl

You might be missing image at environment/world HDRI slot.

Can you share screenshots and a .blend file?

I just found how and where !
have to know where it is i guess

but looks like I had a world map that was no there or loaded
so I remove it and now seems ok

but thanks for feedback
happy cl
