How to enable texture viewing in the uvw editor
If I select a texture through selection, the size of the coordinate grid changes, e.g. my texture is not square, but elongated.  That is, the coordinate grid should not change to match the texture 
Help me how to enable displaying texture applied to an object in uvw editor?

Hi,

In the Edit UVWs, Options menu, click Preferences,

Check the option: Use Custom Bitmap Size,

3DS Max will use the values just above it where it reads: Render Width, Render Height.
