Any experienced with Scripting in Softimage?

*

I am really sux in scripting and math.

Wondering if anyone could help on this.
I think a very simple script would do the trick ( I think... lol)

I imported a City Engine city with lots of geometries and materials.
Eachg material has a pong assined by default with a image as texture (difuse)

I was playing with thie inside Softimag/Arnold.
But Phong doesnt goes well with ARNY.

I need assign the Standard ARnold MATERIAL.

But there are thousands of objects!
Each one has a phong assigned with a texture map.

Is there a way to change each pong to a standard arnold material, without lost the texture map connection?
Cause i dont wanna miss those texture maps...

Any help will be very appreciated

:)
