Cloth Room Introduction Creating your first cloth simulation
Poser 5’s cloth room can be a little rough to get started with. There are lots of knobs and buttons. You have to do things in just the right order to even get started.
This tutorial will help you load and simulate your first Poser 5 cloth. The tutorial is click by click and is intended for Cloth Room beginners.
Poser 5 or higher
A Dynamic Cloth Object.
The figure the cloth was designed to fit.
Load the Actors …
Start a blank scene in Poser Load your figure don’t pose it yet.
Load the Dynamic Cloth Object.
Make sure the object is parented to the Hip of the figure.
Select the cloth object
Press [Ctrl] + I to open the object properties
Click Set Parent
Click the “hip” of the target figure
Tip: Ctrl + I is the “hot key” to open the Properties Box
Create a cloth simulation …
Switch to the Cloth Room
Click “New Simulation”
Check the number of frames is the same as your animation
Set the collision options
The vertex to polygon and polygon to polygon setting help produce more accurate simulations, but take longer
The Cloth self collision is useful for draping clothes that will hit together. It prevents the cloth from passing through it’s self.
Set the number of drape frames (Some items don’t need draping. See the documentation that came with your item.)
Tip: You can change these setting by clicking on “Simulation Settings…”
Click on Clothify.
Select the object to clothify
Click the Clothify Button
Tip: If the cloth object is selected when you click Clothify you won’t have to find it in the list, it will already be selected. Saves a few clicks.
Collision Settings …
Click “Collide Against”
Put an “X” in the box in front of your figure
Check the “Start Drape from Zero Pose” box. (Unless your cloth uses a special starting pose)
Tip: You can speed up calculation by unchecking parts that won’t effect the cloth simulation. For example you could uncheck all the upper torso, head and hands for a skirt simulation.
Now you can pose your figure …
Now you can finally pose your figure. Set the animation slider at least 10-20 frames in. This will give the cloth simulator some frames to get the cloth into the pose you want to use. If you are just doing a still image you will use the slider to pick the best frame when the calculation is done and render that frame.
Tip: The more movement in your pose from zero, the more frames you need to give the cloth room to get the cloth into position.
Before you hit calculate make sure of these things
The figure is completely zeroed at frame 1 or set to the cloth’s starting pose.
Check the hip translation.
Check the body translation
The cloth prop was parented to the figure hip at frame 1
You can check in the Hierarch Editor to see if the prop is parented.
The Simulation Settings > Simulation Range frames are set to the same length as your animation
Finally what you’ve been working for! This will probably take some time. You may even think your computer is locked up. It usually takes a minute or two before the progress bar even shows. Each frame can take up to a minute to calculate. Patience!
Tip: The cloth room “thinks” at 30 frames per second. Keep in mind what real cloth would do as it moves at the speed your pose moves. This one point will help you get great results.
My cloth gets bunched up around the figure’s arms.
Move the model more slowly. Use more animation frames to get the figure into position.
Turn down the friction values so the cloth will slide over the are easier.
It ran the calculation and then jumped back to the default pose.

The cloth doesn’t look like I want it to.
There are lots of dials in the cloth room Unfortunately there is no “Talent” dial. It will take time and experimentation to get professional results. You will run lots of simulations before you can get just what you want on the first try.
Give the simulation more frames to work with. Add frames the the animation and Simulation Settings.
The cloth may need more “Drape” frames
The cloth falls (flies) off my figure!
You may need to add a “constrained” group to the cloth. Use the cloth room “edit constrained group” button and add some vertexes to the constrained group. Neck lines and waist lines are prime targets to be constrained.
You may have forgotten to select the “Collide against” figure in the collision settings.
The simulation fails and won’t restart.
This is a Poser 5 bug. Delete the simulation and recreate it.
Always save before running a simulation.
Check for crushed cloth. (Under arm area is common)
Use more steps per frame.
How can I keep the figures fingers and toes from poking through the cloth?

This third part of the tutorial begins to explain adding shadows. Many people use different colored brushes, you can get a much more natural effect using gradients, lassos, dodging and burning. Related

From ChrisOatley.com We’ve been talking recently about the importance of lettering when making your own comics. In my two posts Comic Balloons & Clarity and The Comic Lettering Spell the discussion in the comments turned toward discussing our own processes. Personally, I use a program called Comic Life. A lot of you asked to see […]
