Crash related to morphtargets and faces without splines #38
Description
When using a skeletal mesh with morph targets and the "Remove Faces Without Splines" set to true, FFurMorphObject::Update_RenderThread crashes on line 110 MorphAccumulatedWeightArray[RemappedIndex] += MorphAbsWeight; with Exception 0x80000003 encountered at address <mem_address>, Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:E:\UnrealEngine\Source\5.4\UnrealEngine\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 758] Array index out of bounds: 6888 into an array of size 6707
The morph target which is being iterated on contains faces where splines were removed. Prior to spline removal, there is no crash and morph targets function fine. Perhaps the vertices that were removed from the fur via spline removal are still trying to be manipulated by the morph target.
