"This serialization version is not supported anymore. Please convert this file"

[Lucasnns]

I'm using in the 3.0 version a khepera iii model, but I have a problem, this version is using only core from my CPU, and with multiple robots it's just extremely slow processing. In the newest version I notice a better multi core structure, so I wanted to import the model robot but I can't, it's showing the message: "[CoppeliaSim:error] This serialization version is not supported anymore. Please convert this file." Can someone help with any of this two problems (the model import and the multi thread)?

That typically involves using some intermediate version of CoppeliaSim (e.g. see here https://forum.coppeliarobotics.com/view ... hp?t=10674) as backwards compatibility with old serialization versions is only maintained for a while.
