I'm trying to create an atlas for mesh objects to reduce draw calls. Hi, I recently tried your extension and it looks great! Thanks for your work. TexturePacker does this for you - with a single click. If you want to use normal mapped sprites for dynamic light effects in your game, you have to create sprite sheets with the same layout for normal maps and diffuse maps. You can even hand off the sprite sheet creation to your artist.

The free TexturePacker Importer plugin for Unity automatically re-imports the data as soon as you re-enter Unity's editor. The polygon packing mode generates tightly packed sprite sheets, reducing the memory amount compared to rectangular packing algorithms. You see all changes applied to the sprite sheet in real time. TexturePacker comes with an easy to use UI that allows you to manage the sprite sheets. The tracer tolerance slider gives you control over the optimization. TexturePacker's high-quality polygon tracer creates meshes with a low vertex count and overdraw. A too low vertex count, on the other hand, is also bad because this hands much work over to the GPU.
So reducing the number of vertices is important. Vertices are expensive - because the CPU is required to transform them. Unity creates triangle meshes for all sprites - but the generated meshes often have too many vertices and high overdraw.
Use the free TexturePacker Importer from Unity asset store to easily import the sprite sheets into Unity. Pack normal maps for 2d dynamic light effects.Easily manage & pack sprite sheets for you Unity project.
