General Recommendations for 3D Assets and Materials
Geometry recommendations
Avoid automatic simplification by the ByMe platform by providing assets below the threshold, for each level of detail.
When simplification is required, the result is better if the source has lots of triangles (within stated absolute maximums) than if it is just above the triangle count maximum.
Supported unit is millimeter (mm).
A 3D model should have the exact dimensions of the real objects being represented - this is important to enable the ByMe platform to mix different products in the same scene.
Normals must face outwards.
Y axis must always point towards the back of the model. Choosing a good default orientation is key since Geometry Editor only allows 90°manipulations.
3D Model must be aligned with the axes.

Valid textures import format: .png and .jpg ; jpg files should be provided at 100% quality setting.
PNG files should be used only if texture contains transparency.
Only standard materials are compatible with DAE and OBJ import. For 3DS Max 2016, this includes “skyline” materials. Engine-specific materials and shaders (such as VRay materials, IRay materials, etc.) are not supported.
Files must not include lightmaps merged into diffuse maps.
Normal map: JPG or PNG. OpenGL normal map format (Y invert).
