Maybe you can set the URO of SkeletalMeshComponent by C++；
块引用 MeshComp->bEnableUpdateRateOptimizations = true;
MeshComp->AnimUpdateRateParams->bShouldUseLodMap = true;
MeshComp->AnimUpdateRateParams->MaxEvalRateForInterpolation = 4;
MeshComp->AnimUpdateRateParams->LODToFrameSkipMap.Add(0, 0);
MeshComp->AnimUpdateRateParams->LODToFrameSkipMap.Add(1, 3);
MeshComp->AnimUpdateRateParams->LODToFrameSkipMap.Add(2, 5);
MeshComp->AnimUpdateRateParams->BaseNonRenderedUpdateRate = 6;
Or set true for the details “Enable Update Rate Optimizations” of SkeletalMeshComp ;
Sorry for my English.
