Maxscript - render command memory issue

walterlow

Hello guys, in my script I've noticed that my 3ds max memory usage stays relatively the same when i write it like this:

render camera:leftCam outputwidth:spn_frameWidth.value outputheight:spn_frameHeight.value vfb:chkbox_vfb.state cancelled: &bCancelled progressbar:true outputfile:fName framerange: (interval spn_rendStart.value spn_rendEnd.value)
render camera:rightCam outputwidth:spn_frameWidth.value outputheight:spn_frameHeight.value vfb:chkbox_vfb.state cancelled: &bCancelled progressbar:true outputfile:fName framerange: (interval spn_rendStart.value spn_rendEnd.value)

however when i try to put it in a for loop the memory builds up significantly

for i = spn_rendStart.value to spn_rendEnd.value do 
(
	if not bCancelled then 
	(
		RenderFrames stereo:chkbox_stereo.state stitch:chkbox_stitch.state
		index += 1
		slidertime +=1
	)
)

in my RenderFrames() it is basically the same as the first except without the framerange parameter.

I've narrowed the problem down to creating a new bitmap inside RenderFrames(). I thought that close() bitmap would solve that memory issue but it still persist. any ideas?

Try gc() after the close() inside the loop.

thanks for the info monster. just found out that freeSceneBitmaps() did the trick.
