Bug Report: Incorrect Local Rotation for Multi-Brush Structures

[Yue]

 

Description: There is an issue with rotating multi-brush structures using the properties window in Ultra Engine. When selecting multiple brushes that form a single structure and applying a rotation value (e.g., -90 degrees) in the properties window, the brushes rotate individually rather than maintaining their local relationship within the structure. However, using the rotation gizmos in the viewport works correctly and rotates the entire structure as expected.

Steps to Reproduce:

1. Create a structure using multiple brushes.
2. Select all the brushes that form the structure.
3. Open the properties window.
4. Enter a rotation value (e.g., -90 degrees) in the rotation field.
5. Observe the result in the viewport.

Expected Result: The entire structure should rotate as a single unit, maintaining the local relationships between the brushes.

Actual Result: Each brush rotates independently, disrupting the structure.

Additional Information:

• The rotation gizmos in the viewport function correctly, rotating the entire structure as a unit.
• This issue is illustrated in the attached images: the first image shows the incorrect rotation using the properties window, while the second image shows the correct rotation using the gizmos.

Thank you for your attention to this issue. Looking forward to a resolution.

Best regards, Yue

What is a "structure"? Are the brushes all parented to the same entity?

It appears to be working as I would expect.

 With the gizmo it rotates perfectly when I have several selected

With the gizmo it rotates perfectly when I have several selected. They rotate in relation to a center axis, when I pass values directly in the editor window the rotation is done locally on each element.

That's the correct behavior. The properties show you the rotation of all entities. If their rotation x, y, or z value is different then the field will be blank, indicating there is not one single value for all selected objects.

If you change a rotation value in the properties, that change is applied to all selected objects.
