Hi,
Having issues with corona pattern mod.
please have a look at what i am trying to achieve.

and this is what i get when i rendered it...

here you will notice those strange grid type patterns occurring in the chains more prominently.

The chain design is similar but idk why is that grid appearing.
This is the actual chain design.

This is what i modeled and applied on my surfaces.

Kindly if someone could guide me through this. Thankx
