If I am rendering with blender, can I open a new project while it is rendering?

I will show you what I do when I try to open another page...

Ok, so while my project is rendering, I open up the Blender iconenter image description here

This opens up a new pageenter image description here

I save this projectenter image description hereenter image description here

Then I open up the document(while my other project is rendering)

enter image description here

Then this pops up enter image description here

I always thought that if I rendered something huge that would take weeks to render, couldn't I also be working with Blender on another project? I know this a lot but it would really help me if someone figured it out...

  • If you want to do both, I suggest opening a new instance of Blender instead so one will render and you can work on the other – Playjoy Jan 17 '17 at 23:39
  • Instance? What is an instance? –  Jan 17 '17 at 23:42
  • Each time you run a program, you create an instance of that program. To open another instance (also known as windows) just open Blender again as you normally would while keeping the other one open. – Playjoy Jan 17 '17 at 23:45
  • I can open and work on another page, but when I save it and open it again, it says,"You can't open the application "blender" because it may be damaged or incomplete. –  Jan 17 '17 at 23:57

    @BlenderWonder Can you edit your post and list the exact steps you are currently taking? Screenshots would help as well as the current version of Blender and operating system you are using. When asking be as detailed as possible so you can possibly get more interest and possibly answers to those who see your question for the first time. – iKlsR Jan 18 '17 at 00:24

  • It would be, except I can't open the page. So its a different problem... –  Jan 19 '17 at 17:32

Just open a new instance of Blender:

Windows: Right click on the blender icon then choose Blender. This will open new blender instance.

Linux: Just run the application another time

Mac OS: By default, only 1 instance of an app can be run. You can work around this limitation by invoking Blender from the terminal command line. open -n /Applications/blender.app

  • Can you break down what that means(Mac OS)? –  Jan 18 '17 at 01:24

    So you opened a blender instance, run the rendering, keep this blender opened. Then open terminal in your Mac then copy this command open -n /Applications/blender.app and paste it in your terminal and run it, it should open another instance of blender while keeping the other instance opened. – Tak Jan 18 '17 at 01:57
  • I did what you said but it then said-The file /Applications/blender.app does not exist... –  Jan 18 '17 at 02:38
  • @BlenderWonder yes because I don't know where you are placing the blender folder. you can use this open -n /place your blender directory here/blender.app – Tak Jan 18 '17 at 02:39
  • It still says files do not exist, if I find my blender folder and use terminal with open -n /Applications/blender.app, will it work? –  Jan 18 '17 at 02:45
  • @BlenderWonder Could you open the folder where blender is located and then right click on the blender app icon then get info and send me a screenshot of that? – Tak Jan 18 '17 at 02:46
  • I can't open a picture in the comments. –  Jan 18 '17 at 02:59
  • you can use pasteall.org but now it's getting more complicated a video will be better to show what exactly you do – Tak Jan 18 '17 at 02:59
  • We should discuss on chat, but I need more reputation. –  Jan 18 '17 at 03:06
  • @BlenderWonder Please accept the answer to this question and open another question showing the other problem with steps and screenshots and send me the link of the new question here and I'll have a look at it. – Tak Jan 18 '17 at 03:11

I once tried to do it myself and i find that when you open a new blend file during render it takes time for the blend file to really open(When I started it was slow and after a while it worked fine), but if u give it some time, 5 minutes perhaps depending on your computer, it will open completely and then it should work.
