How to install the pack:

Unzip the folder and copy paste it into your decalmachine folder where you keep the other packs.

I put mine into documents, which looks like this:

C:\Users\nick\Documents\DECALS4DM\Decals\Nick Burton sci-fi decal pack 1

Alternatively if you didn’t change the native folder, you’ll find it in:

AppData\Roaming\Blender Foundation\Blender\2.xx\scripts\addons\DECALmachine\assets\Decals' then refresh library in Addon preferences:

You might have to open blender, go to the addons, decal machine and tap on update library.

for more info, read the RED ME BEFORE INSTALL PDF file I put into the downloads.
