Make sure all objects or materials have unique names, avoid using identical names for different objects, it can cause problems. If your model has repeated names, you can just add numbering to differentiate them.
Avoid using any non-standard characters in naming, use only letters, numbers and symbols like _ and -. Non-english letters and other special characters might not be recognized in some software and appear incorrectly.
Try to stick to whatever naming structure you chose for the naming. For example if you use numbering for different objects, use the same numbering structure for all of them.
Do not use spaces in any object or material names, use symbols like underscores ( _ ) or dashes ( - ) instead of spaces.
