I can’t seem to find it anymore, was it removed?
I don’t know what do you mean by ‘Dirt’ material, is it even existed in before?
Nevermind, I haven’t built in a LONG time so I remembered the ‘Pebble’ material as the dirt material.
Could’ve also mistaken the Terrain materials (Ground or Mud) as a Part material, for the record.
If you’re looking for some neat dirt textures however, try using brown slate for solid dirt, and brown grass for more powdery looking dirt
You can use slate or pebble etc for dirt but if you want a dirt texture you can find one online or in the roblox library and insert a texture onto the surface of the part and it should function the same as the material tool (depending on the texture used).
I don’t ever recall a ‘Dirt’ material, however I know you can always use grass and color it a darker brown color, that gives the appearance of dirt if that’s what you were referring to.
Worth noting that long ago the grass material had patches of dirt.
