Wrap deformers never seem to work right when I first try. Here's some notes for my future self:
- You select the thing to be wrapped first, and the thing doing the wrapping second. This is backwards to most deformers.
- Exclusive bind :
- Maya notes: When on, the wrap deformer’s target surface will behave like a rigid bind skin and Weight Threshold is disabled. Each surface point on the wrap deformer’s target surface will only be affected by a single wrap influence object point.
- My notes:
- This is the most optimized way to wrap something, providing the best performance.
- It appears that 'Max Distance' still seems to have an effect with this, mainly just causing it to break at random values.
- Auto Weight Threshold
- Maya notes: When on, the wrap deformer automatically sets the optimal weight of the wrap influence objects’ shapes by calculating the smallest Max Distance value that will ensure every point on the mesh is affected by an influence object. This option is on by default.
- My notes: This can take a looooong time to calculate on complex assets. Disables 'Weight Threhold' and 'Max Distance'.
- Weight Threshold :
- Maya Notes: Lets you manually specify the influence of the wrap influence objects’ shapes based on the proximity of their components to the objects being deformed. Depending on the point density (for example, the number of CVs) of the wrap influence objects, changing the Weight Threshold can change the overall smoothness of the deformation effect. Values range from 0.000 (smooth) to 1.000 (sharp). Use the slider to select values from 0.000 to 1.000. Default is 0.000. The Weight Threshold takes effect within the influence area defined by the Max Distance value (below).
- My notes:
- Low values tend to make the wrappee's points stick better to the wrapper.
- Max Distance :
- Maya Notes: Specifies the influence area of wrap influence object points. By limiting the influence area with Max Distance, you can manually limit how much memory Maya requires to perform the deformation. The less memory required, the better the performance. Using Max Distance is especially useful when you are working with high-resolution wrap influence objects. The Weight Threshold takes effect within the influence area defined by the Max Distance value.
- My notes: Use this to speed things up, make it as low a value as possible.
