Ball Rig

Hi guys, here I am coming back after a long time with all my brand new assignments of my 4th sem.  This is my first assignment where we have make a ball by taking simple polygon sphere in Maya , texture it and then rig it such a way so that it can perform stretch and squash.

So I am just briefing how I am able to rig it, first create a polygon sphere and rename it as ball and then texture it.

After that I listed down my rig requirements.

My rig requirments are:

*  Stretch and squash control
* Transformation Control
* COG control


Then I came back to Maya , then I created three curves of basic shapes[ triangle, circle and cube] and then coloured it using a rig box then I renamed it.  After that I created a squash deformer for sphere and then aligned it in such a way that it could perform stretch and squash properly. Then I did a interactive stretch and squash control using set driven method.


I loaded the stretch  control curve as driver and the shape node of the deformer as driven. I made a link between translate y of the  triangular curve to factor of the deformer and keyed it. Then I created a group of ball and deformer and then I aim constrained it to the trianguoloar curve(Parent). Then I grouped the curve and ball group into one group and renamed it has ball group.

Then I took the translate curve(parent) and parent and scale constrained it to the ball group.  After the I made a group of of transformation curve and ball group and renamed it as transformation group.  Then I selected the COG curve(parent) and did parent and scale constrain to transformation group. finally this is how my outline looked after all these.

And I also did a test rig for the ball, a simple bounicng ball.



 
Thank you.

Global Light Rig Setup

Hi everybody in this assignment we setup a global light rig which will be very helpful to present models and add related shots. This rig is really awesome it  gives amazing output in software render with all the soft shadows and the model looks really fantastic, I never thought software render can give such a beautiful output.  And its portable also. The light rig will have two sets of directional lights, one set on the top which behaves as a sunlight and another set act as ground light.  The direction of directional lights can be controlled by their respective controls. And the intensity of the lights can also be controlled by the attribute given in the master light rig control I used node editor to get this connection. I have downloaded a model from -https://free3d.com   Model credits: https://free3d.com Here is the diffrence between various render outputs: 1) With only directional light 2)  With only Light Rig( 0.1 intensity ) 2)  With only Light

Blend Shape Deformer

Hi guys , it is a small activity we got after we learnt blend shape deformer , we created a plane and did only half if the expression i=of the face then  used wrap and blend deformer again to get the symmetrical another half then blended both of them with master face to get both side of expressions. And here is the video,

Hi, in this assignment we were asked to create background from the great Malgudi days serial, we took reference of cartoon drawings made for Malgudi days, then we also took some village side photographs and props to get out Malgudi BG done, and here is the output that I could come up with...  Thank you.
