			====Method: Animesh====

			'''[[Animesh User Guide\|Animesh]]''', or '''animated meshes''' is a technology introduced by Linden Lab in November 2018 to address most of the shortcomings of the above methods, and widen the range of possibilities, with next-to-zero impact to the region simulators, and a little impact on the viewer (but not overwhelmingly so).

			Since Second Life was launched, we ''always'' had 'animated meshes'. The problem was that it was just ''one'' — namely, the standard avatar body mesh. Everything else was un-animate-able and mostly frozen in place, with the exception of flexiprims and Linden Trees. Thus the several methods described above to give a sense of movement to an object, each with its limitations.

			With mesh replacing both sculpties and primitives, and becoming the ''de facto'' standard for content creation, animesh allows our meshed objects to be animated in the same way that avatars can be animated!

			In particular, animesh allows:
			* Using any standard mesh (within reasonable size limits and less than 100,000 triangles or so)
			* A pseudo-skeleton, equivalent to the original standard avatar body, will be implied for that mesh, so the mesh can be properly rigged
			* Animations are uploaded as BVH files for the original standard avatar and become assets exactly like avatar animations
			* The mesh item, for all effects, is driven by an Animation Overrider
			* Animations run on the viewer, not the simulator; this means that there is far less effort by the physics engine to track a moving, animated object. This is exactly how user avatar animations also work!
			* Animesh can also be attached to user avatars, within limits; this allows animated pets perched on one's shoulder, for example
			* There are special attachment points on user avatars using the [[Project Bento Resources and Information\|Bento skeleton]] for wings, tail, etc. which can be "animeshed" in conjunction with the avatars themselves

			[[Animesh]] has its own entire section here on the SL Wiki.

	* SL won't allow you to upload a texture larger than 1024x1024 pixels so resolution may be an issue for textures with a lot of frames.
	* Animated textures on a prim can be on one face, or all faces with one direction, so sometimes you have to break a moving section up. (point out Sylvan's flipped UV wheel trick here)

	The hippo flies are an example of using model design and animated textures together. The model has several sets of wings. The different frames of the texture each have one pair of wings visible, so when animated the hippo flies seem to flap their wings. Mesh models don't look glitched like a sculpt does when a texture with transparency is applied.		The hippo flies are an example of using model design and animated textures together.
