[Closed] diffuse map on/off toggle

-- This script only works on standard materials but that can easily be fixed by adding more 
 
-- checks in the ValidateMaterial function. You will have to make a special case for 
 
-- multi-sub objects
 
fn ValidateMaterial mat =
 
(
 
if (classof mat == standardMaterial) then
 
return true
 
-- add extra checks here
 
)
 
-- If you supply a value to the forceState variable it will force al the materials on or off.
 
fn ToggleDiffuseMapEnable forceState:undefined =
 
(
 
if selection.count > 0 then
 
objs = selection as array -- If we have a selection use it
 
else
 
objs = objects as array -- otherwise use all the objects in the scene
 

 
-- we must keep track of our materials otherwise we'll keep toggling it on and off if multiple
 
-- objects use the same material
 
local matsChecked = #()
 
 
 
-- loop through all the objects, ignoring those without materials
 
for obj in objs where obj.material != undefined do
 
(
 
-- Check if the material is valid
 
if (not ValidateMaterial obj.material) then
 
continue
 

 
-- check if the material we're looking at is in our list of checked materials
 
-- if it is skip it
 
if (findItem matsChecked obj.material > 0) then
 
continue
 

 
-- toggle the diffuseMapEnable variable in the material
 
if (forceState == undefined) then
 
obj.material.diffuseMapEnable = not obj.material.diffuseMapEnable
 
else
 
obj.material.diffuseMapEnable = forceState
 
 
 
-- add the material to the list of checked materials
 
append matsChecked obj.material
 
)
 
)
 
-- Toggle All Diffuse Maps
 
ToggleDiffuseMapEnable()
 
-- Enable all maps
 
--ToggleDiffuseMapEnable forceState:true
 
-- Disable all maps
 
--ToggleDiffuseMapEnable forceState:false
 

Sorry if its not properly indented, this WYSIWYG editor doesn’t like me very much when it comes to indenting

many thanks for your help
