Crash in GPUSkinCache.cpp when opening VRM4U_PostToon.umap

Hi there, I am using the latest GitHub version of VRM4U and as soon as I try and open the VRM4U_PostToon.umap to test the PostToon material setup, Unreal immediately crashes with the following:

Assertion failed: DispatchData.PreviousPositionBuffer != DispatchData.PositionBuffer [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Engine\Private\GPUSkinCache.cpp] [Line: 2056]

I don't believe it will be hardware related as I am running PC with Nvidia 3090 and 128GB Ram.

Thanks for the report. It will be fixed in the next version. This is a level issue; there is no problem with BP_PoseCopyToon itself, so you can continue to use it.
