Objects with same material looks different

Hi, I’m experiencing some problems with rendered material. I have created a certain material and assigned it to multiple objects in the scene, but when I try to render, some of them still look the previous material I assigned. What can I do to fix it?

THANKS!

Which renderer are you using?

If some objects are grouped that may cause the issue.

Also you may want to check and see if your objects are assigned by layer or object to receive the material you’ve placed on it.
