*Many small (in vertex numbers) Objects/Meshes have a far worse negative impact on performance than a single Object/Mesh with very high vertex numbers. | |||
*Combine all different parts of the Model into one single Object/Mesh, with the exception of parts that need to be animated, or of transparent parts. | |||
** '''Blender''': Select some objects and press {{Key press|Ctrl|J}} to join them into one Object. The new object origin/transform/orientation/name will be based on the ones of the last object selected. | |||
*Use different unique names for each of the Objects in a Model file. Even more so when the different parts need to be animated. | *Use different unique names for each of the Objects in a Model file. Even more so when the different parts need to be animated. | ||

*Split transparent parts into their own objects | *If you need a part of the model to be visible from both sides, duplicate it in place and flip the normals. The extra geometry overhead is negligible compared to the extra work generated by double-sided faces. | ||
*Split transparent parts into their own objects.<!-- and place at the end of the object list --><!-- I'm not sure this is not some kind of placebo--> | |||

*The interior should be a separate Model. Having it separate enables delayed loading of such models in multiplayer/AI contexts.
