Unlit Billboard

[matthew.clifton]

Hi all,

Is there a way of creating unlit billboard materials (or unlit materials deriving from mesh_base)?

My use case is:
I'm rendering a galaxy and there are no light sources within the world. I was using sphere meshes with an emissive material which is working very well. That said, as I'm plotting 100k+ nodes I don't need the geometry overhead of spheres; a flat plane billboard with an alpha texture would easily suffice. I've been playing around with both billboard and mesh_base materials but cannot get them to render visibly without a light in the scene.

Any assistance would be greatly received and i hope the above makes some sense.

Best regards and many thanks in advance,
Matt.

Matthew,

You can create material that will not react to the lightning by assigning albedo texture to the emission slot and slightly tuning the other parameters. More details you can find in this thread: https://developer.unigine.com/forum/topic/4133-lighting-and-transparancy-issues/?do=findComment&comment=21690

There is also a sample in SDK in Demos -> Samples 2.x -> materials/pbr_,materialballs where unlit materials are shown.

Thanks!
