Mad Pony Decimator

This ZBrush Decimation plugin uses Tessimate to decimate your model. It provides the flexibility to set a desired target point count or a percentage of reduction.

It also provides the options to re-project, keep original and make the model symmetric in 3 directions.

Like the Tessimate button, it keeps your existing polygroups. The result is not as good as Decimation Master but its 5 time faster.
