[Closed] Getting the reference of a custom plugin?

Hello everyone!

I’m new to both maxscript and this forum.

I’m having issues calling a function in my material from outside. In a general script I’m gathering all the geometries and would like to see if those geometries are using my custom material. If they are, then call a function defined in that material. Here’s the pseudocode.

------ myMaterial.ms ----------------
plugin material MY_MATERIAL
name:"My material"
classID:#(23452345,234523455)
extends:DirectX_9_Shader replaceUI:true version:0.1
(
   fn boop =
   (
      print "boop"
   )
)
------------------------------------------

----- otherScript -----------------------
include myMaterial.ms

fn do_things = 
(
   for geom in Geometry do(
      geom.material.boop
   )
)

-----------------------------------------

My question would be if there is any way cast the materials in the geometries to MY_MATERIAL and call the function boop if the cast is successful.

I’m also unsure if I have the right approach to this problem.

Thanks!
