Forcefield material not working as expected

[Yor_ick]

Hello there, I’m Yor_ick. I need some help! I did something cool with this tree, and it involved the forcefield material. It works as expected when you play on graphics 7 or less, but it’s not how I want it at graphics 8 or higher.

I’ll show you what I mean:

Graphics 7:

Graphics 10:

I hope you can help me out.

You could just make it black, get the same mesh but inverted and slighty bigger, make it neon orange instead all the force fields, it might not look exactly the same but you will have an orange outline like in the first pic
