{{note|Note that range animations often used for LOD are very expensive (any time you move, every range animation must be evaluated), and give a real advantage only if they remove a very large amount of details (like 1000-2000 triangles), so it's not useful in many cases of for example scenery objects or cockpit details.}} | {{note|Note that range animations often used for LOD are very expensive (any time you move, every range animation must be evaluated), and give a real advantage only if they remove a very large amount of details (like 1000-2000 triangles), so it's not useful in many cases of for example scenery objects or cockpit details.}} | ||
{{tip|Instead of using range animations for each little detail you could group many details together and do the range animation for them all, for example having one range animation for an entire cockpit instead of several dozens.}} | |||
* If a model has to be detailed to a ''very high'' degree, use multiple objects with different levels of detailing, and switch between them based on LOD with a [[Howto:Animate models#Range|range animation]], or split the detailed parts to make them a couple more objects that add details incrementally. | * If a model has to be detailed to a ''very high'' degree, use multiple objects with different levels of detailing, and switch between them based on LOD with a [[Howto:Animate models#Range|range animation]], or split the detailed parts to make them a couple more objects that add details incrementally. | ||
* An alternative, less expensive way to support LOD is applying a [[Howto:Animate models#Select|select animation]], that can hide an object based on some property, for example hiding a cars side mirrors if "detailed" level is at less than 1500m (which is the default), indicating that the user has a less powerful machine. It is less flexible, but allows everyone to enjoy your models. | * An alternative, less expensive way to support LOD is applying a [[Howto:Animate models#Select|select animation]], that can hide an object based on some property, for example hiding a cars side mirrors if "detailed" level is at less than 1500m (which is the default), indicating that the user has a less powerful machine.
