"Out of video memory",When i upgrade my project from 4.26 to 4.27

when i upgrade my project to 4.27, and then run in pie, that is a error dialog popup. say “out of video memory trying to allocate a rendering resource.”

[2021.09.22-03.31.23:040][824]LogD3D11RHI: Error: D3DDevice failed CreateBuffer VB with ByteWidth=-1011213360, BindFlags=0x89 Usage=0, CPUAccess=0x0, MiscFlags=0x0
[2021.09.22-03.31.23:040][824]LogD3D11RHI: Error: Result failed
at E:/UnrealEngine/Engine/Source/Runtime/Windows/D3D11RHI/Private/D3D11VertexBuffer.cpp:103
with error E_OUTOFMEMORY

the ByteWidth is negative…what is the matter?

additional information:
in the afternoon, i do some debug.
when i delete groom component, it’s work without error.

I found the cause of the problem. I checked the Use Attach Parent Bound option of the Groom component. And the parent node Skeleton Mesh is doing a very large skeletal movement, resulting in Bounds being very large, greater than (30000, 30000, 30000), Therefore, the calculated buffer space needed to be generated is too large, which leads to a prompt of Out Of Video Memory, but UE4.26 does not have this problem. I guess the algorithm has been changed, and I will not go into it further. The problem is solved.
