[Closed] Mapbutton usage?

Hi,

I have a scripted material plugin that is supposed to feature custom map buttons. Some of those mapbuttons shall be used to delegate the picked maps to the map slots of the extended standard material.

My problem is, that the “on picked” method does not work at all since I connected the mapbutton to the rollout parameters.

parameters main rollout:rMaps
	(
		useMultiTex type:#boolean default:false ui:chkMultiTex
		multiTexMode type:#integer default: 1 ui:ddlMultitex
		useDiffuseMap type:#Boolean default:false ui:cbUseDiffuseMap
		mapDiffuse type:#textureMap ui:mbSelectDiffuseMap
		mapMulti type:#textureMap ui:mbSelectMultiMap
		
	)
	
	rollout rMaps "Maps"
	(
			checkbox cbUseDiffuseMap "Diffuse"
				align: #left
				triState: 0
			label labDMap "Map:"
				align:#left
				offset:[100,-20]
				triState: 0
				enabled:true
			mapbutton mbSelectDiffuseMap "None"
				align:#right
				width:150
				offset:[0,-20]
				height:18
		group "Multi Texturing"
		(
			checkBox chkMultiTex "Use"
				align:#left
			label labMTMode "Mode:"
				align:#left
				offset:[100,-20]
			dropDownList ddlMultiTex ""
				items:#("ENV_MAPPING","TEX_PAINT","ADD_BLEND","BUMP_MAP","LIGHT_MAP","NRM_MAP_DIR_AND_POS","NRM_MAP_DIR")
				align:#right
				offset:[0,-21]
				width:150
				enabled:true
			label labMMap "Map:"
				align:#left
				offset:[100,0]
				triState: 0
				enabled:true
			mapbutton mbSelectMultiMap "None"
				align:#right
				width:150
				offset:[0,-20]
				height:18
		)
		
		on mbSelectDiffuseMap picked map do
		(
			print "hello"
			delegate.diffuseMap = map
			delegate.diffuseMapEnable = true
		)

I’m getting no “hello” when I pick a map

Suggestions anyone? Thanks in advance!

Bye,
Marco

edit: Actually I’d like to completely reject the “on picked” functionality and have the mapbutton directly connected to the delegated diffuse channel of the extended material.
