My question is if i was to make a video game and distribute it free to friends what meshes can I use legally. Are the Poser models  legal to use?  I heard p5 and up are strictly prohibited, but what about P2 and P4?

If the model is butchered by reducing the number of polys does that change anything? If so, what would be the number of polys qualified as being okay to use.

Are the skeletons legal to use in a user created mesh?

Are the bvh exported files legal to use?

Thanks, I know this seems to be asked all the time and should be answered by the EULA but I am not sure of the answer.
