Material Library Links

[ronwC2GC6]

I'm having an issue where I've created new materials but they seem to have some links to each

other that I didn't intend. What I'm doing is generating a custom Content Center with Part Numbers that are driven by size. For instance a .375-16 UNC x 1" bolt Grade 5 bolt Results in a part # BHC6UNC16G5.

That's all working well. To get the G5 I made a custom material with that name. I also made others such as G8, 8.8, 10.9 and BAl which is a Black painted aluminium rivet. My problem is that for some reason when I set the density of BAl material it also changes the density in my 8.8 material. 
Is there a link somewhere that I accidentally created when the material was made?

How do I correct these issues?

Well thanks, see what else comes up

Look at the material physical property.

Each material has Appearance and physical property.

You need to choice or create different physical/appearance.

Usually when you copy a material, IV will make a copy of each.

If you change the name of material which I do all the time, it'll use same property as before.

That would make sense. Except that when I do rename the physical properties it changes in the other one.

If I change the physical property name in 8.8 to 8.8 then the physical property name in Al also changes to 8.8. And also visa versa

Can you do a screencast and show us how you are changing the density and how it is affecting the other material?

Ahh unfortunately I figured out another solution and don't have that problem anymore.

I selected materials and appearances from the Asset Browser. This has fixed the issue and given me the correct weights.

Thanks all for your efforts
