object using new renderer in object viewer not blend texture correctly than using old renderer

hello

this time when i import an object to object viewer the shading seems different, in old renderer if the mesh has round/half round shape the texture can blend so the mesh look smooth but in new renderer the texture can't blend correctly so the mesh look sharp.

object link:

It's being caused by the blender exporter defining both a daytime and a night-time texture.
With the GL1.2 renderer (and the GL3.2 renderer with BVETS Hacks enabled, which is by default in the main game), this disables ambient lighting effects on the face.

If you wish to create the same effect in a current / supported manner, please set the face to emit pure white, e.g. 255,255,255

thanks leezer3 the mesh is fixed with a command you suggest to, even the texture blend correctly .
