Tension Maps
How do you use tension maps to simulate cloth folding in C4D?
All I have is this picture:

And this text from the manual to go on:
“You can use the tension tag to write information in a vertex map that defines how much stretching or compression is occurring in each polygon that is being deformed by one or more deformers.
You can then use this information for a number of purposes. One of the main uses is to create natural-looking folds and stretches as a mesh deforms. This is achieved by loading the vertex maps generated into vertex map shaders, which are then used as layer masks inside a layer shader. The layer masks are used to blend in the various stretch maps and fold maps in the areas where stretching or compression is occurring.
You can use this layer shader in the displacement channel, for example, to simulate folds on the object.”
I’ve tried recreating the effect from the picture with no success.
I would just use clothilde but it doesn’t make sense since my character is wearing tight-fitting clothing.
Any help would be greatly appreciated. 🙂

Create the vertex maps you want to use, then give your object a tension tag (tags>character tags>tension), and drag your vmaps into the appropriate slots.

Sorry, I was asleep at the switch on that one! What you do is create a tension tag for your object (tags>character animation>tension). Then click on the “fix tension” button to set the initial state. Then click the two “make map” buttons to create the vertex maps that will be used in the layer shader.
Then follow the diagram (which is from the help manual, btw) showing the shader setup, and use the shader however your want (e.g., in the displacement channel).

Sorry it took so long to respond…
Your instructions worked like a charm!
Thanks a bunch! 🙂
