Daily Blender Tip 351: Adding a Decal with nodes

You probably know you can add a decal with a separate object using the shrinkwrap modifier for example. But do you know you can use a few nodes to get the same result? This quick tip shows you how.

Best Tipp I found for using Decals on Objects, without fiddeling around with Shrinkwarp, Boolean or other wierd stuff!
Thank you!
Glad you like it!
