ah, okay It's way harder than I thought to create Materials... But it's probably easyer when they don't need to be renderable... I have no idea what U3dreal have done, hehe... Sure I'm going to add your window/buttons here's what I've made so far: It's not using the converter yet... Code: global proc abWin() { window -title "About Maya -> Indigo" -h 200 -w 300 -sizeable false; columnLayout; text -label "About Maya -> Indigo" -w 300 -h 40 -backgroundColor 1 1 1 -font "boldLabelFont" -align "center" ; text -label "" -w 300 -align "center"; text -label "Creators:" -w 300 -font "boldLabelFont" -align "center"; text -label "Matt B. (mostly)" -w 300 -align "center"; text -label "Arne OOG" -w 300 -align "center"; text -label "" -w 300 -align "center"; separator -w 300; text -label "" -w 300 -align "center"; text -label "Copyright © 2006" -w 300 -align "center"; showWindow; } window -title "Maya -> Indigo Controll Panel" -h 600 -w 400 -menuBar true -sizeable false; menu -label "Edit" -tearOff true; menuItem -label "Save Settings"; menuItem -label "Reset Settings"; menuItem -divider true; menuItem -label "Close" -command "closeWindow"; menu -label "Help" -helpMenu true; menuItem -label "About Maya -> Indigo..." -command "abWin"; columnLayout -columnAlign "center"; text -label "Maya -> Indigo Controll Panel" -w 390 -h 40 -backgroundColor 1 1 1 -font "boldLabelFont" -align "center"; tabLayout; shelfLayout Materials; shelfButton -annotation "Diffuse Shader" -image1 "commandButton.xpm"; shelfButton -annotation "Phong Shader" -image2 "commandButton.xpm"; shelfButton -annotation "Specular Shader" -image3 "commandButton.xpm"; setParent ..; shelfLayout Lights; shelfButton -annotation "Physical Sky" -image1 "commandButton.xpm" -command "sphere -r 0.5 -n Sun;"; shelfButton -annotation "Sky Light" -image2 "commandButton.xpm"; shelfButton -annotation "Specular Shader" -image3 "commandButton.xpm"; setParent ..; shelfLayout Misc; setParent ..; setParent ..; //Settings frameLayout -collapsable true -label "Render Setting" -w 390; columnLayout -columnAlign "center"; checkBox -label "Metropolis" -align "center"; checkBox -label "Pathtracing" -align "center"; checkBox -label "Bidirectional" -align "center"; separator -w 390 -h 12; optionMenu -label "Logging"; menuItem -label "True"; menuItem -label "False"; setParent ..; setParent ..; frameLayout -collapsable true -label "Environment" -w 390; columnLayout -columnAlign "center"; checkBox -label "Physical Sky" -align "center"; checkBox -label "Sky Light" -align "center"; separator -w 390 -h 12; checkBox -label "HDR map" -align "center"; attrNavigationControlGrp -l "HDR file"; setParent ..; setParent ..; button -w 390 -h 30 -label "Generate XML code" -align "center" -command "indigoOutput"; showWindow;
