Stencil ReadMask as parameter don't work

Hi

I would like to set the stencil ReadMak value as parameter of my shader, but unity say compilation error.

I set the Ref value as param and it works good, but impossible to set the ReadMask or WriteMask

Exemple:
...
Properties
{
_StencilRef ("Stencil Ref", Float) = 0
_StencilMask ("Stencil Mask", Float) = 0
}

....
Stencil
{
Ref [_StencilRef] //Work good
ReadMask [_StencilMask] //Don't work !!
WriteMask [_StencilMask] //Don't work !!
Comp NotEqual
}
....

An idea ?

Thanks
Laurent

 

Ever get this figured out?

 

This is pretty late but you can do something like this:

Properties

{

   [IntRange] _ReadMask ("ReadMask [0:255]", Range( 0 , 255)) = 1

   ...

}



...



   Stencil

   {

       Ref [_StencilRef]

       ReadMask [_ReadMask]

       ...

    }
