bRenderInMainPass of SkeletalMesh doesn't Work on Mobile

UDN
Description

bRenderInMainPass of skeletalMesh doesn't work on mobile. Even if bRenderInMainPass is set to false, SkeletalMesh will be drawn on MainPass on mobile.

Licensee has shared the following correction code to us.

MobileBasePassRendering.cpp

 

void FMobileSceneRenderer::RenderMobileBasePass(FRHICommandListImmediate& RHICmdList, const TArrayView<const FViewInfo*> PassViews)
{

...

for (const FMeshBatchAndRelevance& MeshBatchAndRelevance : View.DynamicMeshElements)
{

// add MeshBatchAndRelevance.GetRenderInMainPass()
if ((MeshBatchAndRelevance.GetHasOpaqueOrMaskedMaterial() || ViewFamily.EngineShowFlags.Wireframe)
&& MeshBatchAndRelevance.GetRenderInMainPass() )
{

...

}

 

Steps to Reproduce
  1. Put SK_Mannequin on  level
  2. Set the skeletal mesh component's RenderInMainPass to false
  3. Build and check package on Mobile
  4. SK_Mannequin render on MainPass
