Free tutorial: Smart Workflow for Adding Decals

pavla writes:
Decals are an effective way to add isolated details to a model without having to incorporate it directly into the main model or main texture maps. In this video, Thibaut demonstrates a clever workflow for creating and projecting flexible, clean decals using Blender booleans and projecting UVs from the camera view.
There are several methods for projecting decals to the surface of a model. This method is particularly reliable and flexible and worth knowing.
The application with this technique is broad. Example of decal usage include:
- Graffiti
- Stickers
- Industrial labels
- Isolated damage / Bullet holes
- Blood / paint / ink spatter
- Puddles
The intro barrel’s grungy metal material can be found on Blendwap.

Sorry but that doesn’t look smart, yet it looks very blenderish
While I’m not sure why there’s so much destruction/ vertex breakage going on, I do know this same effect can be done with UV Project https://docs.blender.org/manual/en/dev/modeling/modifiers/modify/uv_project.html , I created a 5 minute demonstration on how to use the UV Project modifier with Eevee here:
