[Closed] write a text file after render each frame

Maxscript has tools to execute scripts before or after render (each frame or whole sequence).

Launched via callbacks it can do what you want

fn createLog = (		
		f = ( (getdir #scripts) + "\\log.txt"	)		
		if doesFileExist f then
		(
		  st = openFile f mode:"a"
		)else(
		  st = createFile f
		)
		format "- TimeStamp [%] %
" currenttime timestamp() to:st
		close st
	)--end fn
	
	
	-- #preRender			--Sent before rendering is started.
	-- #preRenderFrame		--Sent just before each frame is rendered by the renderer.
	
	-- #postRenderFrame		--Sent just after each frame is rendered by the renderer.
	-- #PostRender			--Sent after rendering has finished.
	
	callbacks.removeScripts id:#doLog
	callbacks.addScript #postRender "createLog()" id:#doLog

ah cool, thank you for you help. i will test it.

edit: Yes it works!
