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:
- Industrial labels
- Isolated damage / Bullet holes
- Blood / paint / ink spatter
