How to place Decals in Blender ?

Hey there :slight_smile:
My question is if there is an easy way to place decals on to objects without to change the texture itself ?
The only way i found was to project them on to the object but is there an easier way ? Maybe something like there is in some gameengins where you can drag and drop them on a surface and move them around ??

Hope you understand what i mean and you know an answer. :slight_smile:

Here is a link to a short video how to.

Yes. Object texture coordinates in Blender internal render and UV project modifier in both Cycles and BI.

Thanks for the quick reply help out a bunch :slight_smile:
