Unions change the position of textures

Hello there! The problem here is that when I put textures in parts, it’s normal. But when I put textures in unions, it just becomes, sorta warped.

TEXTURES IN PART:

TEXTURES IN UNION:

What can I do to avoid, or stop this from happening?

Please research texture wrapping such as in blender.

The Union you’re performing changes the mesh that the texture would normally wrap around.

You can only fix the textures by exporting the Union as a mesh, unwrapping the mesh in a3D program like blender, adjusting your texture to fit on the unwrapped mesh, and tempting the new texture.

Granted I’m not a modeller so some of my phrasing may be off, but that’s the gist of it.
