Iray Burned Decals and Shaders is a collection of tools meant to simulate the after effects of a fire, including smoke, soot and damage. There is a suite of decals which can be projected onto any surface, using the standard daz decal node.
There is a collection of overlay shaders, which will map onto any mesh with an appropriate tiling UV. There are standard shaders, which will replace your current material/shader. Finally, a pack of VDBs including smoke and fire are included to add the final touch to your render.
