I want to change a mesh material with a button

Hi Nawrot,

Thanks for your answer. So I’ve tried to switch to dynamic objects an the script is now working wich is great but I’m also losing my lighting, and reflections sphere don’t seem to work anymore on mobile ? I get the message : “Update reflection captures only works with an active feature level of SM4 or greater.” My lighting is based on one HDRI skylight an sky so the reflections are the most important feature to light my objects… I have to admit that i’m quite confused with that, it was working fine until now.
