| Summary | 0005402: Model browser renders 3D previews for past models, overlaps current selection | ||||
| Description | I've gotten this annoyance with DR since I started using it but never got around to reporting it. The model browser (potentially affects the entity and prefab browsers too) will occasionally draw a previous model you've selected on top of the current selection, causing both to display in the 3D preview and overlap. When this happens I either need to deal with the glitch or restart DarkRadiant to get rid of it till it occurs again. Though I couldn't pinpoint the exact cause beyond doubt, what seems to trigger this appears to be using undo: If you add a model, undo with Control + Z, then try adding another model, you get the previously added model also being rendered in the window. | ||||
| Steps To Reproduce | Right-click in a 2D viewport and choose "Create model...". Play around with creating multiple models, duplicating, undoing / redoing your actions, etc. At some point when you open the Choose Model window again, you'll see additional models render on top of your currently selected preview. | ||||
| Additional Information | Repro steps I found: - Start DR - Create Model > darmod/nautical/anchor.lwo - Deselect - Create Model > darkmod/nautical/boat.lwo - Undo - Create Model > both anchor and boat are rendered on top of each other | ||||

Confirming the entity browser can do it too. Screenshot_20201114_013515.png (128,630 bytes) |

Apparently the scenegraph used by the ModelPreview is connected to the same global UndoSystem as the rest of the map, causing the interference. The TraversableNodeSet::connectUndoSystem() method is accessing GlobalUndoSystem() - which needs to change. The fix requires similar refactoring as in moving the LayerManager instance to the map's root node, to separate it from other scenes. This is more work, so I'm not going to fix this for the upcoming 2.9.0. But maybe a quick fix can be done to purge existing models from the ModelPreview scene before doing anything. |

That quick fix sounds like a good idea too if possible in a healthy way. While this one doesn't cause crashes or prevent using any features, it is annoying when a large model remains forgotten in the preview and you're currently looking at smaller models, as you won't be able to preview them and easily see exactly what you're selecting, due to the larger ghost model covering the mesh of what you're currently previewing. |
