RenderFidelity
This property determines the level of detail that the solid modeled part will be shown in. It can be set to the possible values of the Enum.RenderFidelity enum.
The default value is Automatic, meaning the part's detail is based on its distance from the camera as outlined in the following table.
| Distance From Camera | Render Fidelity |
|---|---|
| Less than 250 studs | Highest |
| 250-500 studs | Medium |
| 500 or more studs | Lowest |
SmoothingAngle
This property represents an angle in degrees for a threshold value between face normals on a solid modeled part. If the normal difference is less than the value, normals will be adjusted to smooth the difference. While a value between 30 and 70 degrees usually produces a good result, values between 90 and 180 are not recommended as they may cause a "shadowing" effect on unions with sharp edges.
Note that smoothing does not affect the normals between different materials or different colors.
UsePartColor
Sets whether the PartOperation can be recolored using the BasePart.Color or BasePart.BrickColor properties. When true, the entire union will be colored as per Color or BrickColor. When false, the parts in the union will maintain their original colors from before the onion operation was performed.
Phương Pháp
SubstituteGeometry
Substitutes the geometry of this PartOperation with the geometry of another PartOperation. This makes it easier to utilize the geometry of a solid modeling operation like UnionAsync(), SubtractAsync(), or IntersectAsync() but maintain properties, attributes, tags, and children of the main part such as Attachments, Constraints, ParticleEmitters, light objects, decals, and more. This approach also circumvents the potential "flicker" of completely replacing the original PartOperation with another.
Note that if you're calling this method on a PartOperation with child Attachments or Constraints, you should calculate the affected instances with CalculateConstraintsToPreserve(), then drop those whose recommended parent is nil.
Tham Số
