Rendering several maya scenes and cameras
5 Comments
Page 1 of 1
THE PROBLEM:
You need your animation rendered by the morning. You have 3 scenes to render each scene is saved in a different maya file and one of the scenes you have two cameras, you need both of them rendered and you are a tired artist not a programmer.
THE SOLUTION:
Open notepad
type "render my_scene.mb"
Save as click_me.bat or whatever you want to call it but it must have the .bat extention ( in the note-pad file extension drop-down it only offers .txt
Double click the .bat file you have just made and Maya renders your scene as you set it up in your render globals. Maya doesn't even have to be open and it is faster than if you rendered it from inside maya.
So much for the scary "command-line"
Now that we have that running...lets render from three different maya files...
save as click_me.bat in your scenes folder....and they get rendered one after the other as set up in the render globals in your scene file...nice and simple...
You can also choose which camera you want to render from and which frames you want rendered, so lets say you have two cameras in tank_firing.mb camera1 shows the tank turning and firing from frames 25 - 45 but then you want your close up camera ( which you renamed barrel_cam in maya ) to show the action from frames 35 -45
-s is the abbreviation for start and -e the abbreviation for end, -cam tells maya which camera to render
The only problem here is that the images have the same name and are going into the same folder....set up like this it will write barrel_cam images over the camera1 images, we need to rename the images or render them in differnet folders; to render them into different folders type in -rd and then just copy and paste the path from explorer, remember to create the folders, if they do not exist they will not be created automatically
Alternitively you can rename the images, using -im and then just call the images whatever makes sense, don't add a .tga or .jpg ( as in firing.tga ) or it will still add the suffix from the render globals and call the image firing.tga.tga
Image sizes, image types, in fact all the settings from render globals can be written into your batch render file and if you want to write more complicated render instructions you can use the list below, but only make things as complicated as they need to be below is some of the commands and you can find more in maya help files...
remember to do a quick check that everything is working before get your well earned sleep and let your computer do the rest of the work...
Happy rendering
