Adding JCM's to Clothing

Summary

If the default morphs that are automatically created upon running the Transfer Utility are not as good as they need to be, tools exist for fixing these problems. Creating JCM's or Joint Corrective Morphs is one technique to fine tune these problem areas.

Process Overview

  • Pose the figure
  • Export the figure
  • Load the figure in modeler to fix the issue
  • Steps to save the JCM
  • Load and use Reverse Deformations
  • Test

Foundation

This example shows a coat that didn't look right when the head and neck were bent backwards. The desire is to build a morph to fix the coat when the head was bent back.

Step By Step

Follow the steps below to create a JCM to fix a clothing item's bending issues.

Step 1: Pose the Figure

Pose the Genesis neck (with the clothing item loaded). Bend the neck backwards all the way (30%, X-rotate). This places the figure and clothing item in the proper location for making the necessary modeling changes.

Step 2: Export

Export the Genesis figure and Coat from DAZ Studio 4 as an .obj file. File > Export... > obj

Step 3: Load in Modeler

Load the .obj model into the modeling software (we use Modo). Now fix the collar of the coat to look the proper way in this bent position.

Step 4: Steps to save the JCM

In preparation to save the model it's important to delete Genesis from the scene. Now save out the coat as JCM morph. Make sure genesis is still posed exactly how it was when you exported the model from DAZ Studio.

Step 5: Load in DAZ Studio 4 Pro using Reverse Deformations

Load the morph into DAZ Studio 4 Pro using Morph Loader Pro... and make sure to set REVERSE DEFORMATIONS to True.

Wrap-Up

These techniques can be used in any area of the model. The goal of the Transfer Utility is to have as few corrections as possible. But the nature of many products will require fixes to show the item in it's best light. The more accurate and natural your product bends and looks, the better received the product will be to the consuming public. Take time to test your product to be sure it works as best it can.
