Editing specific bitmap offset, output and other proproties

Try to see here for more idea:

Amazing work! Thanks for sharing :)

Ok so I hit another wall :-)

When I restart max and start from fresh scene I'm missing few nodes and my script crashes ehh

Anyway can some suggest a fix for missing values? - The script wont start because the value for spinner dont exist because the envi node don't exist.

global tete=1
rollout studio "Studio Settings" width:343 height:501
(

	on studio open do
	(
		try( -- TEMPORARY FIX
		if(tete = scenematerials["IBL_Main"].environment_shader.output.output_amount) != undefined then tete else
		(
			tete = 1
			)
		)catch()
		)

		
	button btn_Create_IBL "Create IBL" pos:[8,8] width:144 height:24
	button btn_Delete_IBL "Delete IBL" pos:[160,8] width:144 height:24

	spinner spn_Intensity "" pos:[80,39] width:72 height:16 range:[0,10000,tete] scale:0.1

I see you have Create button... (so you want to use script to create and edit material...)
Than your script should check first if material "IBL_Main" exist... you can use if map != undefined then .... or try()catch() to check it. If material doesn't exist script will turn off spinner or more rollout items. See in code below.

When button Create "IBL_Main" is pressed - script will create material and turn on spinner.

I think it can look this way:

rollout studio "Studio Settings" width:343 height:501
(
	button btn_Create_IBL "Create IBL" pos:[8,8] width:144 height:24
	button btn_Delete_IBL "Delete IBL" pos:[160,8] width:144 height:24
	spinner spn_Intensity "" pos:[80,39] width:72 height:16 range:[0,10000,1] scale:0.1
	
	on studio open do 
		(
			if scenematerials["IBL_Main"] != undefined then 
				spn_Intensity.value = scenematerials["IBL_Main"].environment_shader.output.output_amount 
			else 
				spn_Intensity.enabled = false
			
			--- OR ---
			--try(spn_Intensity.value = scenematerials["IBL_Main"].environment_shader.output.output_amount)catch(spn_Intensity.enabled = false)
		)
	
	on spn_Intensity changed state do 
		(
			if scenematerials["IBL_Main"] != undefined then scenematerials["IBL_Main"].environment_shader.output.output_amount = spn_Intensity.value else Messagebox "Can't find \"IBL_Main\""
			
			--- OR ---	
			--try(scenematerials["IBL_Main"].environment_shader.output.output_amount = spn_Intensity.value)catch(Messagebox "Can't find \"IBL_Main\"")
		)
		
	on btn_Create_IBL pressed do (  
		-- CREATE IBL_Mat
		-- use your code here
		
		-- TURN ON SPINNER
		spn_Intensity.enabled = true
		)
		
	on btn_Delete_IBL pressed do (  )
)
createdialog studio

So first I would declare all items in rollout with default values, than use "on open..." if map exist it load spiner value otherwise it will turn off spinner.

Hope it helps.

Hey mate

Thanks I cant believe I mist it ! I had to reference the switch shader and then I could've sub reverence the bitmap parameters as you've showed me. Oh dear thanks!!!!

no prob man :) Happy I could help!

Hey,

If you do:

print (getpropnames scenematerials["IBL_Map"]) 

you will get properies names:
#Background
#environment
#background_connected
#background_shader
#background_paramName
#environment_connected
#environment_shader
#environment_paramName
#TheList
#Shader_Version

Bitmap holders are: background_shader and environment_shader
so the code can look:

scenematerials["IBL_Map"].background_shader.output.output_amount = 5.53 

or

sceneMaterials["IBL_Map"].background_shader.coords.U_Offset = 0.05 

Hope this helps,
