I've been working on a simple shader that uses transparency (blend mode) and the spherical billboard rendering options. I've noticed that as soon as you select billboard metallic and smoothness textures or colours are ignored (basically things appear to go metallic / shiny).

Is this a bug? Real shame as I need my billboards to a be non reflective and have found this editor excellent for pulling together surface shaders.

Hello,

Thank you for using ASE, we would be happy to help. What's your current Unity and ASE version? Can you please share a sample shader with the problem present? It would be extremely helpful if we could test it on our side.

Thanks!

Unity 5.6.2f1
ASE 1.1.0

(I notice the smoothness colour is set to something other than zero (in the editor it's black). Could this be the issue?

Thank you for sharing the shader. Can you also share the textures used and a screenshot of the problem? I will pass it on to the ASE developers and we will get back to you on Monday as soon as we test it on our side.

We are available for direct contact at [email protected]

Thanks!

OK. I'll email the materials with a link to this thread. Thanks!
