Project currently only uses Default Render Pass, and Pipeline State Render Pass.
1: As Nodes dont set Tag by default, what is the purpose of TagFilter Transparent and can it be removed?

2: What is the purposes of "Draw Objects Transparent" can it be removed?

3: There is no light source in the current scene, what is the use of "Gather Lights Render Pass" can it be removed?

  1. Its purpose is to make sure that Transparent objects are rendered correctly by rendering the opaque objects first and the ones with Transparent tag later on. You may find more information about Transparency Sorting here and in Kanzi documentation page here. If you don't need to render transparent items, you can remove it.
  2. It basically draws the objects with Transparent tag to handle transparency rendering correctly. If you don't have transparent nodes, then you can remove it.
  3. It gathers the lights in the scene and applies to the nodes during the child draw commands. If you remove it, it would also remove Draw Objects Opaque render pass so you would need move Draw Object Opaque up first and then you can remove Gather List Render Pass if you don't need any lights on the scene.

  The Transparent Tag cannot be removed, you can only remove Transparent Object Sources and the render pass.
