Materials 1.47.03 -> 1.5 Rc2 reflect / Refract Interpolat

[stilgarna]

On the picture you can see a Vray 1.47.03 shader into Max 8.0 + 1.5 Rc2...

When you create a shader into 1.5 directly the Min rate and Max rate (refl and refr) are set to -1...

I want to know if there is a script to convert old version param -3/0 to -1/-1...
A script that can work on evrey shader in the scene (even in Multi/Sub)...

I'm not capable of making script...

Please help...

Best regards...
