We recommend using png or jpg files of 2048 × 2048 pixels.
Within a scene, you can drag and drop an image or a zip file with textures over a 3D model. If you want to prepare a material zip file, make sure that the image files corresponding to each texture contain the respective case-insensitive keyword:
- Color / Diffuse / Albedo: "Color", "Albedo" or "Diffuse"
- Normal: "Normal"
- Ambient Occlusion: "AmbientOcclusion" or "ao_map"
- Roughness: "Roughness"
- Metalness: "Metalness" or "Metallic"
