@stanislas69 Thank you
ok understand, the collada, I'm not a problem, I'm interested in knowing the scales and how to animate correctly, and maybe on the road leave here a small step by step from rookie to novice, and that would alleviate many doubts of many who attract this
Thanks a lot for the link
I also have questions about the engine and the source code, I would like to start from the basics to better understand how this is done, it is not my native language, which is why it is difficult for me to understand words of technical use or some documents.
I want to be able to count on your very valuable guide to be able to participate contributing things so that everyone can enjoy what I can give them
