Configure how a Particle System is baked into a texture.
| BakeRotationAndScale | Bake the Transform rotation and scale into the texture. | 
| BakePosition | Bake the Transform position into the texture. | 
| PerVertex | Bake each vertex of each particle (i.e. 4 vertices per billboard). | 
| PerParticle | Only bake each particle, instead of each vertex of each particle (i.e. 1 vertex per billboard). | 
| IncludeParticleIndices | Instead of only baking triangle indices into the indices texture, bake a 2 channel index texture containing triangle indices and particle indices. | 
| Default | The default baking options. |
