Thanks Crocodilian.

This time around the excersise was to see how many of these low poly people I could stuff into one scene before it becomes impractical.

The answer is 132.  Regarding the speeds, they walk at different speeds. I know this becuase I had to (hand) edit them to avoid walking through each other!

Regarding the manner of the walks. Yes that can be improved. I had 32 individual people using 24 distinct walk loops. The rest was down to replication.

I can probably fit a few more distinct people in at this resolution. The max walk loop to people ratio is 1:1 so maybe 40 people / 40 walk loops.

The other improvements (for next time?) are lower poly people (for more people) and different sizes and gender.
