As part of a larger ‘Environment Pack’ we are creating for the project there are small subsidiary packs that make that up 2 of which are Decals and Particle Effects. The content in said packs are all themed around the ‘British Slum’ atheistic and are to be used in conjunction with the other packs, but should also work as standalone assets.
To add more detail and variation to the environment quickly without having to bake more information into the textures and have it tile everywhere, we are including decals to be projected on the walls and floor. Whenever you see graffiti it is very rare that you see exactly the same piece twice, so using decals was going to be key. But to get the variation we want out of this the default decal actor doesn’t deliver the enough options in it vanilla form.
To overcome this I have made a custom decal actor using blueprint to allow for the use of sprite sheets that hold multiple decals, meaning I don’t have to have a different texture sheet for each individual piece of graffiti. As well it means I can open up a range of editable variables that give even more options for customisation for each instance of the actor.
Here’s a video demonstrating the use of the decal actor and the options available:
