Mesh Quantization

From the basics page:

What is mesh quantization?

A: Memory bandwidth is another precious resource on the iPhone (given the fact that both CPU and GPU are sharing it). iPhone supports 32, 16 and 8bit types for vertex components. Quantizing mesh geometry to use smallest possible vertex size (given some user specified error tolerance) would improve performance by accessing less data.

Has anyone done this or know how to do it? I haven’t been able to find any info on the forum, or even google. We are using Max for our 3d and can’t seem to find any options for it there either, so I am wondering if there are plugins or other software that can.

Thanks

You don’t need to do anything special.

So does Unity automatically do it? I would like to try forcing it to a lower bit depth but can’t seem to find out how.

Where do I set this user specified error tolerance?
