Using too many materials may cause the object to render improperly

Exceeding the recommended number of texture maps will slow down performance, and may cause scenes to crash on smaller devices. 

Recommended number of materials for fastest performance

(These recommendations are based on 2048x2048px texture maps)

Desktop 3D:

• 6 or less for fastest performance; 
• 10 maximum

Mobile 3D:

• 1 material for fastest performance; 
• 5-8 maximum depending on device

AR:

• 4 or less for fastest performance; 
• 5-8 maximum, depending on device

VR:

• 9 or less for fastest performance; 
• 12-15 maximum, depending on device

Reducing Materials

Reduce materials by removing unnecessary texture maps. If you have uploaded your own materials, you can combine their maps using the material ID method.
