Making a Dynamic Shirt and Skirt Set in Poser Cloth Room
This tutorial assumes that you have already made your shirt and skirt in a 3D modelling application such as Wings 3D, Blender, Zbrush, 3ds Max, Cinema 4D, etc. and it picks up at the point where you have imported them into Poser. When modelling the shirt in your 3D application, make sure you assign separate materials for the collar, the cuffs, and the buttons so you can assign them to the various vertex groups in the cloth room. Also be sure to have a "belt" group of polygons at the bottom of the shirt and assign a separate material to them also which will be important in the cloth simulation. Do the same for the skirt, assigning a material for the skirt and also a material for the "belt" polygons.
If you have not already, you would find it helpful to read the tutorial on how to make a dynamic gown which will familiarize you to the steps we will be using in this tutorial.
Creating the Fitted Clothing
1. Load your figure and import the shirt and skirt OBJs. Position and scale them so that they fit your figure as best they can. In my case, the figure is V4, which was what I modelled the clothing for.
2. Go into the Cloth room and click on New Simulation button to to create a new simulation for the shirt.
Click on the Clothify button and clothify the shirt and set V4 as the collision object.
Select the shirt and Set the Collar vertices into the Soft Decorated group and the Buttons and Cuff vertices into the Rigid Decorated group. Run the simulation. It will only take a few frames for the shirt to be fitted.
3. With the shirt prop selected, go to Object--> Spawn Morph Target. Type "Fitted" as the morph target name and hit Enter to create a morph target. Go back to frame 1 and set the morph target to 1 and then click the Clear Simluation button. We will re-run the simlation again later with the shirt already fitted.
4. Repeat steps 1-3 for the skirt but set the collision offset and depth to 1.5. This will make sure that the belt of the skirt is fitted over the shirt.
Also, set the Dynamics Controls values as shown below before running the cloth simulation:
Fold Resistance = 255
Shear Resistance = 320
Stretch REsistance = 510
Stretch Damping = 0.046
Cloth Density = 0.1030
Now you can delete the simulations, parent each piece of clothing to V4 and save the fitted shirt and skirt to the props library as smart props for future simulations.
Running Future Simulations
1. Load the fitted clothing props from the props library.
2. Go to frame 20 and set a target pose.
3. Select the shirt and click on New Simulation button to to create a new simulation for the shirt.
4. Click on the Clothify button and clothify the shirt and click on the Collision Object button and set Victoria 4 as the collision object.
Important: ***Make sure no other objects are included as the collision object. If the skirt is also included as a collision object, you will get some messy results at the bottom of the shirt during the simulation.***
5. Click on the Edit Constrained Groups button. Click the Add Materials button and select the shirt's belt and cuffs vertices on the drop down menu to set the vertices as constrain group.
This will keep the vertices around the waist and wrist in place during the simulation. Click on the Edit Rigid Decorated Group button and click on Add Materials and choose the button vertices to add to the rigid decorated group.
6. Click Edit Soft Decorated Group button and the Add Materials button and add the shirt's collar vertices to the Soft Decorated Group and run the cloth simulation until you get to your target pose. Then you can cancel the simulation at that point.
7. Repeat steps 1-6 for the skirt. Be sure to set the Belt vertices as the constrained group.
The end result is shown below. The important thing to remember is that, when modelling your shirt and skirt, be sure to make a group of polygons to act as the belt on both the shirt and skirt and assign those "belt" polygons as separate material. Then in Poser, you run a separate simulation for each piece of clothing and assign the belt polygons to a constrained group..
