High quality coal material that can easily be converted into multi-coloured gravel.
2048x2048 professional quality textures baked from a high poly mesh,
-Height (R) Roughness (G) Edge mask (B)
-'Random mask' (RGB mask for individual coals)
the additional edge mask can allow a masked opacity to be applied to help blend seamlessly between assets, the random mask can be used to generate a nice random coloured gravel effect with additional AO mask which can be swapped out for one of the channels in the _RM texture if they are not being used for memory savings.
