2.Can i use for texture big image, and use part of it for facet?

Re: Display textured mesh in pcl::visualization::PCLVisualizer
TextureMesh support is very experimental, frail, buggy and poorly
documented as you've experienced already. There are countless bugs
in the issue tracker related to it (although all pertaining
loading from Wavefront Obj files).
You might want to have a look at the pcl::TextureMapping
class and the corresponding source code.
Even the unit test using GP3 is commented out! It shows some
code, so give it a try.
