Part 1: Working with a Rigged Character

Getting Familiar with the Rig Controls

1. Make a Project: Create a Maya project called Lab2 on cs-render in the folder IDS252Sp18/Lab2/MayaProjects/your_name Remember, once the project is created, you must set the project every time you re-open Maya to insure that Maya will save files to the right place.

2. Outside of Maya, go to the IDS252Sp18/IDS252Resources/Rigs folder on cs render and COPY & PASTE the file Ultimate_Bony_v1.0.5fixed.ma to the scenes subfolder of your project.

   Inside Maya, import this file by going to File→import, and selecting the file Ultimate_Bony_v1.0.5fixed.ma which you copied into your scenes folder. In class, we will go over how to work with the difference controls.

   

   Explore the different controls until you are comfortable and familiar with them. For example, pick an image of a figure on the web and see if you can approximate the body pose. (You can google "images person standing" or "images person sitting"). For now, don't try to be very exact. Your goal is just to understand how controls can translate into body gesture. There is no need to save anything just yet.

Creating A Pose

1. Select a person in the class to partner with.
2. Observe that everybody sits differently in a chair due to their physical structure, their personality, and how they are feeling at the time. Together with your partner, experiment with different ways of sitting in a chair, thinking about what each pose conveys about the person. If you want, you can include a table as a prop to rest your arm or foot. Pay attention to the angles of your body, head, arms, legs. After experimenting, each partner should select a single pose to model. Pick a pose that is fairly expressive and/or exaggerated. Using whatever camera you have (e.g. on your phone), take pictures of your partner's pose from multile angles: front, left side, right side, back, from high up looking down, from low looking up, etc. Be sure to get their entire body (e.g. don't cut off feet). Make sure the light is bright enough to see the entire figure and that there aren't objects (other than the chair) blocking the view. Take off coats or other removable clothing. The goal is to get as clear an idea of the pose as possible. Download the photos and place them in a subfolder called reference in the folder IDS252Sp18/Lab2/MayaProjects/your_name on cs-render. You will use these images as reference material for Maya.
3. Each partner: Open up Maya and set the project to the one you created above, i.e. IDS252Sp18/Lab2/MayaProjects/your_name/Lab2 If you have not done this already, create a new scene in your Maya project and import a clean copy of Bony. You goal is to pose Bony based on your reference images. Create a very simple chair and, if needed, a very simple table. These can be made from resized cubes - don't spend a lot of time modeling these!). Make sure the chair and table are renamed (they should called "chair" and "table", and not anything like pCube1!). Scale the size of the chair and table to fit Bony.
4. Pose Bony based on the reference photos you took. Consult with your partner to see if they think you have captured the pose position and personality. Try as best you can to avoid Bony intersecting himself or the furniture or floor. Constantly rotate the view so that you can see what the pose looks like from all angles. Compare with the reference images.
5. Once you are happy with your pose, select several different camera angles to render to images. Consider the placement of the camera which 1) is from an angle that makes the pose easy to read and 2) is from an angle that enhances the meaning of the pose. You should end up with at least 2 images of size HD 540 and in format jpg or png. Place your images in the folderIDS252Sp18/Lab2/FinalImages/your_name

   Your reference photos should remain available in your MayaProjects folder so that we can look at them during the class critiques.

Part 2: Composing a Scene

Continue to work with the same partner. You each will be doing your own composition; your partner will be there to provide help and feedback along the way.

An animation is composed of multiple objects, e.g. the characters and the scenery. In this part of the assignment, you and your partner will combine your poses and the objects you made in Lab 1 in order to each make a single composition.

• Continue to work in your Lab 2 Maya project.

• You and your partner will each create a separate composition. Each composition will use both of your poses.

• Outside of Maya, copy the final posed scene file your partner created, placing it in the scenes folder of your Lab2 project. Also copy over the final versions of your Lab 1 scene files (e.g. temple.mb, glass.mb, saltshaker.mb). Feel free to model a few additional objects if you want.

• Preparing Your Objects: Before using your objects from Lab 1, you need to make sure they are cleaned up. Warning - If you don't clean up the files, your composition scene file will be an utter mess thus making it difficult to transform and duplicate objects. To clean up the files to do the following:

  • Open up one of your files, e.g. temple.mb
  • Select everything in the scene and delete constuction history by going to the menu Edit→Delete by Type→History.
  • Open up the outliner, Windows→Outliner.
  • Make sure that the only objects and groups in the scene are the things you want to be there. Delete everything else including any curves that were used for creating the objects.
  • Make sure everything is named properly. Note, pCube1 is not an acceptable name!
  • Group things that belong together, renaming the group appropriately.
  • Finally, group all the geometry into a single group and name it according to what the object is (e.g. temple).
  • Make sure the grouped object is sitting at the origin (or wherever is appropriate).
  • With the group selected, select the menu "Modify→Freeze Transformation" to zero out the transformation node values.
  • With the group selected, set the pivot point in an appropriate place on the object. Holding down the d key will give you access to the pivot (Alternatively, on Windows, you press the "Insert" key to move the pivot point. On a Mac, you press "fn" key an "Enter" key). Pivot points will become much more important when we begin animation.
  • If you are using the default lambert1 material, you must replace it with a different material that you create (see discussion below on Colors).
  • Save the scene file.
  • Repeat for the next scene file (e.g. salt shaker and glass) in the project.

  Consult with your partner to make sure you both agree that you have carried out the above procedure. The outliner and channel box should look something like

  

• Importing Objects: Once the objects in the individual scenes are cleaned up, you can now combine these objects into one scene for your composition as follows.

  • Create a new scene and save it into project folder (e.g. call it composition.mb)
  • Go to the main menu in Maya and choose File; Import....
  • Select one of your previous scenes to import. The object should appear in this new scene.
  • Repeat to import several more objects. You will need to translate the different objects so they aren't on top of one another.
  • At a minimum, you should import both posed characters along with several other objects.

• Colors: A consistent color scheme can help give a sense of unity to your final image. For this exercise, all your objects should be solid shades from a palette of only 2 colors, plus white and black. The two colors should either be two complements or two analogous colors, e.g. see the color scheme designer - use Free style with 2 colors. You should choose a color palette ahead of time so that you can set the colors of your different objects to fit in with the color scheme.

  In the last lab, you learned how to give an object a color by assigning it a material. Each object should already have its own material but, if not, right click on it and select "Assign New Material". Select either a Blinn if you want a reflective surface or Lambert material if you want a matt surface. In the Attribute editor, click on the gray square next to the word Color and, in the color selector window which opens, select a color. For now, ignore all the other parameters.

  Note, you can easily change the color of Bony to fit your color scheme. Just go to Windows→Rendering Editors→Hypershade and then select Bony's material node.

  As mentioned above in the "Clean-up" list, it is important that you do not use the default lambert1 material otherwise you will have conflicts when you import multiple objects.

• Composition: In the scene you just created, arrange/duplicate/scale/etc the different objects in a way that tells a story or makes the viewer curious. Discuss the options and choices with your partner. Remember that we use the term "story" very broadly. Be careful to think about things such as framing, negative space, symmetry. Refer to the Sesign and Story elements listed at the bottom of the Evaluation Sheet (pdf)

• Rendering: Once you are done putting together your composition, take time to select a camera angle and location. Consult with your partner. The location and angle of camera can have a dramatic effect on the story your image conveys. Render an image with size HD540 using the format png or jpg. It is best to use the Mental Ray renderer rather than the Maya Software renderer if you want better lighting and reflections.

  Rename the rendered image to be composition_your_name.png (or jpg).

• Images to turn in: Copy the image of your composition to same folder containing your other images (IDS252Sp18/Lab2/FinalImages/your_name) which should now contain 3 images: 2 angles of your posed character and the composition. Please name them accordingly.

• Project Folder Organization: Your project folder Lab2 should be on cs-render in the folder IDS252Sp18/Lab2/MayaProjects/your_name. Please clean-up this project as follows:

  • If you don't already have a backup of your scene files, make a copy now!
  • Make sure that your final scene files are appropriately named (e.g. templeCleaned.mb, handCleaned.mb, saltshakerCleaned.mb, pose.mb, composition.mb).
  • Delete all other scene files, i.e. the ones that are no longer used.
  • In the "images" folder of your project, delete all images files except for your final .jpg (or png) images. Most importantly, remove any files with an *.iff extension since these are really big files!

Evaluation

This lab is due at the date given at the top of this lab. It will be graded based on the criteria sheet (see link at top). There will be a peer evaluation in class on the day it is due. It is important that you are present for the critique regardless of whether you managed to finish the assignment or not.
