Where is ENQUEUE_UNIQUE_RENDER_COMMAND_TWOPARAMETER?

I see many rendering examples use ENQUEUE_UNIQUE_RENDER_COMMAND_TWOPARAMETER() macro. I can’t find it in 4.26.1
Has it been removed, replaced? If true,then how do I do something like this:

?

Thanks.

i have the same problem on upgrading my project to 4.26 from 4.23…

just went back a version to 4.25 and got this deprication warning:

Please use ENQUEUE_RENDER_COMMAND instead Please update your code to the new API before upgrading to the next release, otherwise your project will no longer compile.

hope this helps

unfortunatly i cannot find any documentation about how to replace ENQUEUE_UNIQUE_RENDER_COMMAND_TWOPARAMETER() with ENQUEUE_RENDER_COMMAND as it takes different arguments.
However, what i found is this commit from the engine sourcecode where the old function gets replaced by the new.

https://github.com/EpicGames/UnrealEngine/commit/41f6b93892dcf626a5acc155f7d71c756a5624b0

My c++ skills are limited, but in case i can get it to run, i will post it here…

Epic has replaced ENQUEUE_UNIQUE_RENDER_COMMAND_TWOPARAMETER etc with ENQUEUE_RENDER_COMMAND in the latest version. As the guys above said,there is no proper docs regarding this transition, but it is clear from the source commits. In fact, ENQUEUE_RENDER_COMMAND is less confusing too use as well.

You have to pass a Lambda now. Which in my opinion is way better. You can now define as many parameters as you want and only have to worry about knowing 1 nomenclature( in this case ENQUEUE_RENDER_COMMAND)

float sDataA =0;
FStruct sDataB = FStruct();
UObject* sObject = NewObject();

ENQUEUE_RENDER_COMMAND(NameOfCommand/YouDefineThis/)(
[sData, sDataB, sObject ](FRHICommandListImmediate& RHICmdList)
{
RHICmdList.Command()/Choose your Command to execute according to your captured parameters/;
}):wink:

For anyone need help:

ENQUEUE_RENDER_COMMAND(
			UpdateTextureRegionsData,
			FUpdateTextureRegionsData*, RegionData, RegionData,
			bool, bFreeData, bFreeData,
			{
			for (uint32 RegionIndex = 0; RegionIndex < RegionData->NumRegions; ++RegionIndex)
			{
			int32 CurrentFirstMip = RegionData->Texture2DResource->GetCurrentFirstMip();
			if (RegionData->MipIndex >= CurrentFirstMip)
			{
			RHIUpdateTexture2D(
				RegionData->Texture2DResource->GetTexture2DRHI(),
				RegionData->MipIndex - CurrentFirstMip,
				RegionData->Regions[RegionIndex],
				RegionData->SrcPitch,
				RegionData->SrcData
				+ RegionData->Regions[RegionIndex].SrcY * RegionData->SrcPitch
				+ RegionData->Regions[RegionIndex].SrcX * RegionData->SrcBpp
			);
			}
			}
			if (bFreeData)
			{
			FMemory::Free(RegionData->Regions);
			FMemory::Free(RegionData->SrcData);
			}
			delete RegionData;
			});
