i want to use a playcanves model
I have adjusted your title because it does not contribute to a well-organized forum. Also try to formulate your questions better, because it is not clear what you mean.
so i need to know where the models the play canvas creators made what website
i know it is a thing i got a ball on it once
and a box
There are a lot of websites where you can download free models for your game. Using ‘free fbx’ in google search will help you to find the right model.
When you say ‘where’, do you mean where to download them from or where do we store the models that developers upload on our servers?
Which models as well?
robot and yes
download and robot
You can grab it from the store and add to a PlayCanvas project http://store.playcanvas.com/
