Question by cortex · Jul 16, 2011 at 07:55 PM · shadertransparentocclusion culling

Unity Occlusion Culling Glass effect

Hi, my game has glass halls and glass windows using a transparent shader, allowing the player to view buildings outside the glass. The Occlusion Culling is not displaying buildings outside of the transparent shader, it must think the transparent shader is a solid surface like a wall.

How do I view objects through a transparent shader using Occlusion Culling?

Thank you

I don't think this will work. The occlusion culling works by deciding what is visible from where. It does not know about transparency. When generating the occlusion data you may need to remove your transparent walls. You might be able to do this simply by turning off their static flags (which the occlusion culler uses to decide what is fixed and hence can affect what is visible.)
