How to skip (continue) missing map warning while rendering

Here the script:

(
		
		renderers.production = Default_Scanline_Renderer ()
		(

			freeSceneBitmaps()
		)

This should fix your issue. Its not a clean fix but i found it useful for occasion like this. I figured you just want the default button to be pressed so i just pulled some code i found online a while back. Couldn't tell you where i got it but i know i saved it. It uses

dialogMonitorOps

and

uiAccessor

to pretty interact with UI dialogs that come up. I would love to explain in more detail how it works but I just know it works and haven't really dabbled in it to deeply to have a keen understanding of it but this should fix your issue ATM

here is your new code with it implemented

You should write a book if you start to explain the whole process. :)
By the way, great code

i wish i could take credit for it but I can't. I would like to dig a little deeper into it but for now i never had to have more than confirm buttons being pushed.

Wow....Although I didn't know how but its working....Thanks a lot!!! I will try to understand the script...!!

Dialog monitor ops is just a feature in maxscript which allows you to interact with different dialogs that appear.

Here is how it works in your case....Correct me if i'm wrong anyone.

this line of code unregister any dialogMonitorOps with the id:#test. Just good practice to unregister before you register a new one.

dialogMonitorOps.unRegisterNotification id:#test

The function it self is the action that will happen when the monitor ops realizes that a dialog has popped up. The code

uiaccessor

is used to to interact with the dialog. Since the confirm button is the default button when the dialog shows up i just used the

uiaccessor.pressdefaultbutton()

function

					fn checkDialog = 
					(
						local hwnd = dialogMonitorOps.getWindowHandle()
						if (hwnd == 0) then ( false )
						else (
						format "==================================================\n"
						format "%\n" hwndText
						local children = uiAccessor.getChildWindows hwnd
						format "--------------------------------------------------\n"
						for child in children do (
						format "%\n" (uiAccessor.getWindowText child)
						)
						format "==================================================\n"
						uiAccessor.pressDefaultButton()
						true
						)
					)

From here on out you just turn on the dialog ops and make it so it does the work for you. You also register previous function to run if a dialog appears.

dialogMonitorOps.enabled = true
dialogMonitorOps.interactive = false
dialogMonitorOps.registerNotification checkDialog id:#test

At this point you run the script which usually stop because of some form of dialog. In your case it was the line below. I went ahead and commented out the quiet since you do want the dialog to appear.

local vfb = render rendertype:#bakeSelected outputwidth:size outputheight:size  cancelled:&wascancelled --quiet:true

Once thats done you just turn off the dialog ops and unregister your function again

dialogMonitorOps.enabled = false
dialogMonitorOps.unRegisterNotification id:#test 

What max version are you running in? I just applied a bitmap on an obj in 2011. then moved the bitmap into a new folder and tried

render()

which gave me the "continue" dialog. Then I tried

render quiet:true

the dialog did not appear. I noticed you spelled "quiet" incorrectly in your post which leads me to believe you have spelled it wrong in your code. It would still run and not throw up an error so check that first.

Thanks for the reply MKlejnowski.....sorry I spelt it wrong here....but in the script it is correct.....the problem is when I am using my script....some missing texture message comes....if I press "continue"....the rest of the script is running fine.....same thing when I try to do with "quiet:true"....it dosent show any error....but stops the script there!!
