LDraw part 118091p looks fine in Part Designer but imports into Studio with extra geo
2 hours ago
Hey everyone, I'm having a weird issue importing a custom part from the LDraw library into BrickLink Studio and I can't figure out what's going wrong.
The part is 118091p. When I open it in Part Designer it looks completely fine clean geometry, correct shape, everything as expected.
But the moment I open it or export it into Studio 2.0, it shows up with a bunch of extra pieces/geometry that don't belong there, like it's rendering additional parts that shouldn't be visible.
I'll attach screenshots showing the difference between how it looks in Part Designer vs Studio so you can see exactly what I mean.
Has anyone run into this before? Is this a known issue with how Studio handles certain LDraw file types? Could it be related to how the part references subfiles or primitives? Any help would be appreciated!
One more weird thing worth mentioning: if I zoom out, the extra geometry completely disappears and the part looks perfectly fine. But as soon as I zoom back in, the extra geometry shows up again. It feels like some kind of LOD (Level of Detail) rendering bug, but I'm not sure. Has anyone seen this behavior before?

And weird thing with studio - zoom out

After more testing, it seems like the issue is with a specific subpart, not the whole 118091p file. That subpart renders fine and correctly in LeoCAD, Part Designer, and other viewers, but when the overall part is loaded into Studio, it seems like Studio is misidentifying that subpart as a different one entirely and rendering that other part's geometry instead. Zooming in and out actually shows the swap happening in real timeĀ it's not just extra geometry appearing/disappearing, it genuinely looks like Studio is resolving the subpart reference to the wrong file at close zoom and falling back to the correct one at a distance. Feels like it could be a naming collision or a caching/LOD-resolution bug specific to Studio's part lookup, but wanted to see if anyone has run into this exact behavior before.
