Blender Addon: Bulk change all materials to blend mode suitable for Eevee

This addon allows you to easily convert all materials to Blend mode Alpha Clip with one button on the 3D view toolbar and then save the object to the Asset library from the toolbar.

Used for the assets from https://maxtree.org/

as described in the Youtube video by Grant Abbitt

You want the blend mode to be set to Alpha Clip for all materials and there can be up to 6 per asset. [In the example in the above video there are 91 different assets, each file needs its blend mode changed for every material].

Alpha clip mode is needed when used in Eevee to properly display materials transparency.

But it could be used with any blend file if you want to be able to bulk change the blend mode.
