Setting DR servers as pre-render MEL

[Fredrik Averpil]

I'd like to run a pre-render MEL script which erases all DR servers registered and then adds the one I specify.

Would this be possible?
I see that you can add a server with the command vrayAddServer;, but how do you supply the IP address to this command?

I'm on V-Ray for Maya 2.40.01, Maya 2014 (Windows and Linux).

It's possible, but you must read what vrayAddServer() is doing. It's getting the information with vrayReadServers()/vrayReadServersStatus()/vrayReadServersPorts()... edit it, and then set it back with vraySaveServersInfo() and vraySaveServersInfo()

Hi Ivaylo and thank you,

Okay I think I made it work. Some example Python code for anyone else who may want to do this.

def removeDRFiles():
	userAppDir = cmds.internalVar(userAppDir=True)
	# Delete files: server_list.tmp, server_status.tmp
	filepath = os.path.join(userAppDir, 'server_list.tmp')
	try:
		os.remove( filepath )
		print 'Removed ' + filepath
	except:
		print 'Unable to remove ' + filepath
		
	filepath = os.path.join(userAppDir, 'server_status.tmp')
	try:
		os.remove( filepath )
		print 'Removed ' + filepath
	except:
		print 'Unable to remove ' + filepath


def setHostVray(host):

	mel.eval('string $server="' + host + '";')
	mel.eval('string $serverList[] = vrayReadServers();')
	mel.eval('string $serverStatusList[] = vrayReadServersStatus();')
	
	mel.eval('int $maxLen = vrayGetMaxStringLen($serverList);')
	mel.eval('string $entry = vrayDRMakeServerEntry($maxLen, $server, "", "Enable");')
	mel.eval('textScrollList -e -append $entry "vray_server_list";')
	mel.eval('$serverList[size($serverList)] = $server;')
	mel.eval('$serverStatusList[size($serverStatusList)] = "Enable";')
				
	mel.eval('vraySaveServersInfo($serverList, $serverStatusList);')

	print 'Registered ' + host





removeDRFiles() # Removes any previous server entries
setHostVray('192.168.0.100') # Adds server 192.168.0.100
