[Closed] Maxscript – loop – wait for finished rendering?

Hi folks,

is it possible to make a “for-loop” wait for a finished render-process an then contiue looping?
background:

i’ve got variuos “for-loops” walking through focusdistance, focallength, aperture, iso-speed and shutterspeed of the camera. I need this output for a project.

now i don’t want to create thousands of keyframes (which works), because i want to determine the filenames of the renderoutput – therefore i want to use maxscript to start the rendering.

The issue is, to make the for-loops wait for the rendering to finish

short version of the code:


 for a=1 to dist.count do
 	(
 		for b=1 to focal.count do
 		(
 			for c=1 to aperture.count do
 			(
 			   -- change camera-parameters and other stuff
  
 			   --
 			   -- determine renderoutput-filename "aperture_focal_dist.jpg"
 			   -- start rendering
 			   -- wait for rendering 
 				
 			)
 		)
 	)

any suggestions? – or maybe a complete other solution how to get this done?

wait for the render to finish = PostRender CallBack
i think that what you should dig

Thanks.

so – i gotta change it all – packing it into functions and “count” the parameters after the renderjob – and than start it all over again … right?

I would think that if you call the render() function from within the loop it should continue looping after the render is done. It does not happen that way?

I thought that would’nt work – have been working with flash a whole lot – so I didn’t suggest that max would WAIT – and ist DOES yeehaw

Another quoestion:

I’m rendering the scene and a zDepth-pass – how can I define the NAME of the render-element’s Outputfile??? – (needs a special counter in it)

I’m not sure if you can do it from the render function directly, but maybe using the RenderElementMgr interface?

Thanks for the advice – i’m quite new to MS (it’s my third day)

i think i’ve found some source maybe i’ll get it to work for me … ‘m not sure ^^

Well – i found sth. that seems to work – thanks!
