material clone can't create new id

[MasterK]

serialize will use the origin id.

newMat = mat.clone(newName) can't work.

need set newMat.id = newName.

Can you elaborate?

What is the result of " newMat = mat.clone(newName) can't work. " 

[MasterK]

i mean when newMat = mat.clone(newName);

the newMat.id should be newName, but it would be same as mat.id.

[GameMonetize]

newName is for mat.name

I can force the id to be a completely new one if you prefer? (like newMat.id = new GUID)

[Dad72]

The id is often the name of the object I notice.

When you give a new name to a clone, it renames the Name properly, not the id that has the old name of the object.

[GameMonetize]

yep the idea is that you can use the id to keep a link with the original mesh

[Dad72]

It is true that this can be useful.

In this case, you must:

meshCloned.id = newName;

[MasterK]

ok. i did it like you said.

I just find it's not same as before... or maybe it's my wrong feeling.

and when delete some material, the texture will be dispose, and other same id material's texture will also be disposed... I didn't deep look at it... but matClone.id = newName solved my problem.
