[Closed] Desperately need help

fist of all there is a couple comments:

1. According to your code all objects in imported files array have to be editable meshes (because you use getnumverts function)
2. All objects have to have Standard material applied (you check obj.mat.diffuse value)

Second:

1. To make UVW_Unwrap modifier work you have to open UVW Editor (RoofUnwrap.Edit())
2. Number of Geo Vertices has to be the same as the number of Map Vertices (or you have to use RoofUnwrap.NumberVertices() instead of getnumverts to select all vertices)

So, the code should to be:

  for obj in importedFiles do
  (
  	--find roof
  	RoofColor = point4 0.5 0.5 0.8 1
  	diff = obj.material.diffuse as point4
  	print diff
  	if diff == RoofColor do
  	(
  		RoofUV = uvwmap name:"myUV1"
  		addModifier obj RoofUV
  			
  		RoofUnwrap = uvwunwrap name:"myUnwrap"
  		addModifier obj RoofUnwrap
  			
  		RoofUnwrap.Edit()
  		RoofUnwrap.selectVertices #{1..RoofUnwrap.NumberVertices()}
  		RoofUnwrap.rotateSelectedVerticesCenter (degToRad -45.0)
  	)
  )
  

I appreciate your quick response, the code looks cleaner now but i still get the same problem, ill post up the whole thing, maybe you could take another look.

Thanks for your help, Im usually in maya so this maxscript is quite tough to pick up in a day.

well i fixed it, its just that I dont really know how, heres what I ended up with

for obj in importedFiles do
 		  (
 			--find roof
 			RoofColor = point4 0.5 0.5 0.8 1
 			diff = obj.material.diffuse as point4
 			if diff == RoofColor do
 			(
 				select obj
 				modpanel.addmodtoselection (global uvw = uvwmap()) ui:on
 				modpanel.addmodtoselection (global uvwun = UVWUnwrap()) ui:on
 					
 				uvwun.Edit()
 				uvwun.selectVertices #{1..uvwun.NumberVertices()}
 				uvwun.rotateSelectedVerticesCenter (degToRad -45.0)				
 			)
 		  )
