Custom Attributes for All

[mahmutoymaci]

How can I define custom attributes for all editable_poly or editable_mesh object, including the ones I will create new and converting object?

Note entirely sure I understand your request. Could you please write more than a single sentence about what you are trying to do?

For now, I can point towards the "Attribute Holder" modifier, which is a convenient way to attach a CA (and then you can copy-paste the modifier).

Also, take a look at Paul's "PEN Attribute Holder" script at https://paulneale.com/pen-attribute-holder/ in case you want to load and save presets for your attributes.

I will write a script. I will add it to the \plugins folder. Every time I start 3ds Max, "Custom Attributes" will be added to all editable_poly or editable_mesh objects. It doesn't matter what algorithm I will write.

The solution is simple: you need to track all scene callbacks that cover every way a node of the specified class can appear (load, create, clone, convert, etc.).

The challenge is ensuring you have enough experience to verify that your attribute isn’t already applied, is unique, and matches the latest version.

If you are skillful enough, good luck!
If not, please don't make a mess. Someone will have to clean it up later.

Yes, I tried a lot about "callback" formulas but I couldn't find the right one. That's why I opened a topic.

I don't think the idea of adding a custom attribute on each editable node is a good idea at all. However, let's first just figure out why you need it and try to find a suitable solution. So why do you need that? How do you want to use it?

This is a sample. its working good. I want make similiar.

From a system design perspective, automatically adding a custom attribute to every node is a bad idea.

Just create a macro button instead. Cool doesn’t always mean good.
