Thanks, but this is clearly a problem of location along the Y axis.

If I select my entire model with "Select all at all levels" and move it towards the Y axis origin, all artifacts disappear.

Conversely, if I create a short (<3m, 10') wall in that Y axis location with a door and that same texture ...

I'm lost trying to understand what's happening with a tiled texture (I'm trying to replicate a Hardie panel siding)

The texture is simply a rectangle with border

I built a wall, applied that texture, then added a door. For some weird reason, the texture changes where the door ends
