[Closed] Rendering Z-Depth

Im trying to render z-depth with a custom near and far range for my script, however I dont seem to be able to get it to work with my custom depth ranges…

	-- paths stuff
	mPath = scriptspath + "cam_depth.tga"
	deleteFile mPath
	tgaio.setColorDepth 24 --set to 24bit output!	
	
	-- output bitmap
	mSize = 256
	freeSceneBitmaps()
 	
	-- setup zdepth
	mZDepth = Z_Depth()
	mZDepth.enabled = true
	mZDepth.zMin = 0.5
	mZDepth.zMax = 1.5
	mRenderManager = maxOps.GetCurRenderElementMgr() 
	mRenderManager.removeallrenderelements()
	mRenderManager.AddRenderElement mZDepth 
	
	-- render
	mRender = render camera:mRenderCam shadows:false renderhiddenobjects:false mapping:false rendertype:#normal channels:#(#zDepth) useRadiosity:false outputSize:[mSize,mSize] vfb:false superblack:true antiAliasing:false progressbar:true quiet:true 	

		
	-- disable this after render
	mRenderManager.removeallrenderelements()

	-- mooch the depth
	mDepthMap = getchannelasmask mRender #zdepth
	
	-- open the rendered out bitmap!
	display mDepthMap
