Rapid PBR Material Creator is an addon that simplifies the creation of PBR materials to a SINGLE click! Great to use with Substance Painter.

Ultra Fast Material Creation Tool:

Never waste your time dragging multiple textures from the directories to Blender one by one again.
Forget about tweaking and joining tones of nodes to create one material.
Just choose a directory with textures you want to create a new material with or select them manually in popup browser window, set material's name, click "Create Material" button and you are done.

Update Material Tool:

Did you edit textures externally in Photoshop for example?
Or baked new version of textures in Substance Painter or other software?
You can reload them all with just ONE click!
Without this addon, you need to reload each texture individually what is an absolutely frustrating and extremely time-consuming process. 

How To Use It:

1. Choose a path to the directory from which the textures for the new material will be loaded. Alternatively, you can select textures using popup browser window.
2. Set a name for the new material 
3. Choose between replacing selected materials or keeping them and adding the new one
4. Click "Create Material" button

Optional steps:

1. Change suffixes to your own
2. Choose normal map format
3. Setup transparency handling
4. Setup packed textures loading

Additionally, if your textures have been modified externally, click "Update Materials" button to update them in Blender
