Looking a tutorial to make a custom part!

[Travis Cobbs]

The snapshot above was created with snapshot export from user interface. Not perfect (no transparency) but different from yours. (Ldview 4.3 (x64) (2 Jan, 2017) )
Any plans to support texmap with native renderer?

LDView has the following option in its Primitives preferences:

• Draw transparent textures last
  

I discovered after the fact that you must check this option if you want things to work right. It will be removed in a future version of LDView. To set this on the command line, use -TexturesAfterTransparent=1.
