R21 Cor 5 Content Browser

[Flamingo]

Hello,
in C4D R21 the content browser does not show the material or texture, although I can see and render it in the viewport.
Is there something I do not know?
regards
F.

Hi there,

Can you please share some images with us? Are these materials already pre-loaded into the browser or have you saved some custom ones?
