Stencil ReadMask as parameter don't work

Unity Engine
1

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]
...
}

...
