How to Make a Shirt in Maya
Maya is a great 3D animation tool that lets you design 3D models of your project. One of Maya's uses is designing clothes using Maya Cloth. Before you read these directions, make sure you know the basics of Maya so that you can navigate around the program easily.
Instructions
-
Build Your Shirt
-
1
Create the outline of your shirt. Go to your orthographic view in Maya Cloth, and create the outline of your shirt by creating curves. Make sure the curves are going in one direction and that they are closed loop curves (meaning that when one curve ends, the other begins). Be sure to add two curves for each of your armpit holes as well, even if your shirt has sleeves, and two darts on each side where your ribcage begins. There should be 26 curves in all.
-
2
Select all of your curves with the "Select" tool. Now duplicate your shirt outline with the "Duplicate" tool and pull the new shirt outline forward about two units (when you see a "Z" on your screen). This new shirt outline is the front of your shirt, so add one more curve for your collar.
-
-
3
Name both of your shirt outline layers. Select the back shirt outline layer and name it "back_layer", and select the front shirt outline layer and name it "front_layer".
Creating Panels
-
4
Duplicate the curve between the armpit and sleeve. Select the four curves that make up the sleeve and go to the Cloth menu and click "Create Panel". Name the panel "panel_FR_sleeve". Create panels for the over sleeve, both armpits and the torso. Be sure to do this on the front layer and the back layer.
-
5
Select a panel and click "Create Garment". Do this for all of your panels.
-
6
Create seams. Select the curves that are close to one another and click "Create Seam". Name each seam section. Make sure you close up the darts by selecting the curves around the darts and clicking "Create Seam".
-
7
Sew the seams together. Select all of the curves in the front and back layers and click "Create Seam" to sew them together. Name the entire structure "Shirt".
-
8
Make the creases. Make sure the "Crease Angle" is between -180 and 180 degrees, with the sleeves being 45 degrees. Make sure that the "Crease Stiffness" in the darts is 0.5 and set the "cpSticher's Base Resolution" to 400.
Shirt Collision
-
9
Create a poly-body for your "Shirt" object. Create a "Collision Object" and name this new object "Cloth_collide".
-
10
Set collision details. Keep "Cloth_collide" selected and go to Cloth on your tool bar. Select "Create Collision Object". Set the "Collision Offset" to 0.15 and the "Collision Depth" to 0.4.
-
11
Create bounce. Select the "Shirt" object again, and go to attribute called "cpSolver1". Click into "cpSolver" and change the "Solver Scale" to 10 and the "Reflex Frame Length" to 1. This will give you shirt more bounce.
-
12
Click the "Start Simulation" button to get your shirt to drape over the "Cloth_collide". Click "Stop Simulation" when the shirt is where you want it. If you need to do this multiple times to find what you want, go to "Simulation" on the toolbar and click "Delete Cache" to start fresh. When you're satisfied with your results, go to "Save as Initial Cloth State". Animate the "Cloth_collide" to move the object where you want it.
