Complex Warp Deformer Performance Issue (and a tip to avoid it)

pettankon

Steps to reproduce in Live 2D Cubism Editor 5.3.04:

1) Create a complex Warp Deformer (eg; 10x10 or more Divisions, Angle X + Angle Y with 5 keys each at -30, 15, 0, 15 30, and Extended Interpolation)
2) Create a very simple Warp Deformer* (eg; 2x2 Divisions, no keys)
3) Attempt to deform the simple Warp Deformer

This will incur the same deformation penalty as the complex deformer! However...

4) Put the complex deformer into its own Part (folder)
5) The performance is back!

* The performance hit affects other other types (like ArtMesh) and actions (like selection or movement) too



P.S. For the development team: surely this is a cache issue? The complex warp deformer is a sibling of the other parts in the root / parent part, but if it's not selected and not part of the hierarchy, any calculations on it can surely be skipped since it can't be affected? Unless siblings can affect warp deformers in ways i'm not familiar with. At the very least, moving a sibling part surely should not invalidate this cache? If it's a bounds recalculation then bounds of warp deformers should be cached instead of recalculated.

Did you try having both in the same folder, there is an issue with having anything in root, lags the model in general, (to the point it can be 5seconds + lag)

I have uploaded the problematic file and the relevant log file.

Unfortunately it's just showing the name of the method that is taking a long time. The problem is that it's being called even when other deformers that can't affect it are being changed.
