Elements needs to know the texture type of the custom materials, this is done via naming the materials correctly. The supported texture types are:
Color/Albedo map (filename ends with “_a” OR includes “albedo“)
Metallic map (ends with “_m” OR includes “metallic” OR includes “smooth“)
Normal map (ends with “_n” OR includes “normal“)
Height map (ends with “_h” OR includes “height“)
Occlusion map (ends with “_o” OR includes “occlusion“)
For example: A folder named “Bathroom Ceramic Tile” with the files “tile_a.png”, “tile_m.png” and “tile_n.png”.
The supported texture formats are .jpg ja .png. We also strongly recommend using square-shaped pictures with POT (power-of-two) dimensions, e.g. 512×512 pixels.
