Re: collectgarbage question.

have you tried collectgarbage("collect") to perform a full garbage collection cycle? I'm not even sure what it does without an argument: http://www.lua.org/manual/5.1/manual.html

I am sorry. This wasn't a bug but a feature of lua 5.1.4.
I had to add one more collectgarbage() call.

do
      local skel=VRMLloader("aa.wrl")
      skel.dofInfo:setFrameRate(30) 
end

collectgarbage()
collectgarbage() -- two cycles are needed.
