Making an iOS game. I've read in the Unity Manual --> Optimizing Graphics Performance, the following sentence, which I have trouble understanding:
Contrary to the desktop, alpha-testing is very expensive on iOS. If you can replace your alpha-test shader with alpha-blend, do so. Make sure your alpha-blended shaders do NOT contain "a very small cut-off value" alpha-test based "optimization" as such "optimization" will have negative performance impact on iOS.
For example, I have a shadow material applied on a plane that follows my object (to fake blob- shadow) and this is what I see in the Inspector when I select it:
How can I find out if my shader is Alpha-test or Alpha-blend (whatever this may be... :-) )?
