I selected a vertex which has the vertex ID 442
Now I add a symmetry modifier to mirror my model and an editable poly modifier to select the vertex again.
As you can see, the vertex ID changed to 1432.
To mirror morph targets we created our own tool, which keep the vertex index. Open CryTools > Cry MorphManager and open Mirror Deformation.
Here is a little example scene.
On the left side you see a completely symmetrical mesh. On the right is an asymmetrical mesh. Now we want to mirror the right side of the morph(the blue mesh) to the left.
First you have to set your source object. Simply select your main mesh with the neutral facial expression and press the “Select Source Object” button. After you did that, the name of the chosen object will be displayed on the button.
Now you have to save the vertices which shall be influenced by the mirror function. For this select the vertices from one side of the model, without the vertices in the center of your head and press “Save” to save your selection.
After you saved the selection as a file you have to load the file into max. Press the load button and chose the file which you recently saved.
Next time when you open your maxfile you only have to set your source object and load the saved selection.
You will notice, that you are now able to use the right----->left / left----->right buttons.
To flip you object you have the select “New Obj” instead of “Same Obj”
