Unreal already provides a way to lock access to textures: MainTex->GetPlatformData()->Mips[0]->BulkData->Lock(LOCK_READ_WRITE) or MainTex->GetPlatformData()->Mips[0]->BulkData->LockReadOnly(). Then use MainTex->GetPlatformData()->Mips[0].BulkData.Unlock() to unlock the texture.

You can then use MainTex->GetPlatformData()->Mips[0]->BulkData->IsUnlocked() to check if it’s been locked.

I don’t 100% understand your case but it sounds like you don’t really need the two threads writing to the same texture anyways.
