Why should I buy this addon then?
This group node is my favorite one. It faster process and help my texture workflow much easier.
But to use Hex Scatter group node you have to type correctly name of all texture map to run script in Hex Scatter blender file and copy it back to the Project file that you working on. To me, this way is not friendly for new guy even me and not handy to spam in the project. So that me and my friend Duc Thang make this addon like a subtool to faster the process and more friendly to use, with permission of Curtis Holt & Kris of couse.

This addon is a subtool so It will not content any group node of Hex Scatter, you have to have Hex Scatter group node to use.

Version 1.5 Update!
Note: Please uninstall the old version before installing this update.

What’s new in this update:

The addon will now automatically fill the texture slot with the correct texture map when you import, similar to the Node Wrangler.
If the texture map type is not supported by Hex Scatter, it will not autofill in the custom map slot—you will need to choose it manually. Note: The naming rules for the texture map are the same as those in Node Wrangler. If you’d like us to update or expand these rules, please send us a request.

The texture slot now includes a “None” option to select.If the autofill cannot find the appropriate texture slot name, it will set the texture slot to “None” by default. Note: Even when the texture slot is set to “None,” the default Hex Scatter texture will still remain in the texture slot, as the slot must contain a texture (based on the group node design of Hex Scatter). You can now:

You can now:

Search for texture map names within the texture slot.
Search for group node names in the group node slot.
Texture slots and group nodes now display icons in front of them.
Texture slots now include a small preview image in front of the texture map name.
