This page exists within the Old ArtZone Wiki section of this site. Read the information presented on the linked page to better understand the significance of this fact.
This page serves as basic overview of both the Dynamic Clothing feature (included within DAZ Studio version 220.127.116.11 and later) AND the Dynamic Clothing Control plugin available separately in the www.DAZ3D.com online store. This page includes both an overview of the interface and associated controls, as well as useful tips and tricks that will help you get familiar with common work-arounds and common practices when working with dynamic clothing within DAZ Studio.
Cloth Actions Affect: Allows the user to select the cloth operated by the drape function. The user has three options on the drop down menu. All Cloth In Scene, All Cloth on Selected Figure, and all selected cloth.
|NOTE: This selection affects ALL actions done in the lower interface tabs as well! For instance, if you have “All Cloth in Scene” selected, and then try to change the collision tolerance setting, you'll be updating this setting across “All Cloth in Scene” and NOT just the item you had selected in the “Garment” tab.|
Drape: Hitting this button will relax the current active clothing item. This is referred to as “Simulating Cloth” within the DAZ Studio progress window that appears. For those new to dynamic clothing technology, it's helpful to understand how the physics behind this feature work. Put simply, the physics engine is trying alleviate all “energy” that's built up inside of the clothing. Every time you “drape” the clothing, it's trying to make the clothing relax.
During a drape, you may minimize DAZ Studio, or cancel the drape. Hitting cancel will not clear the drape, it will only stop the simulation where it is at. Just like rendering, DAZ Studio is not usable during a drape.
Clear: Hitting this button will return the current active item that has been draped to its original, undraped state.
Single Frame: With this option checked, the cloth simulation will only affect a single frame
|NOTE: When using the “Single Frame” drape mode, the energy that gets created from the “poor man's rig” included with the dynamic clothing can become VERY extreme. Often, best results can be achieved in this mode by applying a pose, draping for just a few seconds, then canceling the drape, and draping again. The first “fast” drape gets the clothing into a better position, that's not quite so extreme. Then, the additional drape begins the process of relaxing the clothing again using a less extreme starting point. This helps remove the 'pent up energy' that the simple rig can often create as it stretches the dynamic clothing mesh in various poses.|
Animated: With this option checked, the cloth simulation will affect each frame of the current animation play range.
|NOTE: Each time you wish to recalculate a drape across an animation, the timeline needs to be reset to the earliest frame that you want to begin recalculating from. For instance, if you have a 200 frame animation, and you wish to recalculate the last 60 frames, you would want to move the timeline frame indicator to frame 140 and then press the “Drape” button to begin re-calculating the last 60 frames again, while preserving the first 139 frames.|
Collide With: This control allows you to select a node on a figure and choose whether or not the clothing will react to it during the simulation. For best results during simulation, un-check any body parts and/or figure nodes that you do not want to interfere with the simulation.
When a user selects collide with, the above window will pop up. This tool is useful when you get distortion in a drape caused by unwanted cloth intersection. In the first image, there were no changes made to the “Collide With” settings. As you can see, Victoria's hand is intersecting with the jacket.
In the following image, collision is turned off on the left hand. And the dynamic clothing is able to realistically relax without experiencing any interference from Victoria's hand or fingers.
|NOTE: We STRONGLY recommend that any hairstyle that comes near the dynamic clothing in your simulation be un-checked so that the clothing does not try to calculate against it.|
All Selectable In Viewport: This option allows dynamic cloth in the viewport either to be selected in the viewport or not. When this option is enabled, you will not be able to select a figures nodes beneath the clothing.
Layering: The Garment Layer list displays the order in which clothing will layer on top of each other. Cloth items on the top of the list will drape over items lower than it. For example, if the Pleated Skirt is above the Gaucho Jacket on the list, it will appear that the gaucho jacket is tucked into the skirt.
Now, if we select the Gaucho Jacket and press the up arrow on the layer list, the Gaucho Jacket will move above the Pleated Skirt. Below, you can see that the Gaucho Jacket appears to drape over the skirt, as if it were “un-tucked”.
Styles: Using the Styles drop down menu, the user can select different styles of the active cloth.
To select a different style, simply open the drop down menu and select the style you want.
|NOTE: When adjusting Surface material settings on a given style, remember that you are only adjusting the surfaces for that particular Style Option. Each Style Option maintains its own set of surface settings that persist as you switch between Style Options.|
Bend Resistance: Bend Resistance is also a very important tool to understand. Bend Resistance controls how much the cloth panel will resist bending during a drape. More bend resistance means you will see a firmer looking cloth, while less resistance will give you a more natural, wrinkled look.
Shear Resistance: Shear Resistance is used to control how much resistance a cloth panel has against shearing. A lower setting will give the cloth a very real draping effect, while a higher setting will prevent separate panels of cloth from shearing through each other.
Damping: Users can use this to affect the damping value of the selected panel. An example of damping could be how a shock absorber works within a vehicle. The shock absorber dampens the wheel from the up and down of the road beneath.
Shrink X: Shrink X is used to shrink a cloth panel along the x axis. This tool is very important, especially when using complex poses. For example, if you have V4 in a pose where her elbow is extremely bent, reducing the Shrink X% will help to clear up some of the distortion brought upon by the extreme pose.
Shrink Y: Shrink Y is used to shrink a cloth panel along the Y axis. This tool is extremely important as well. For example, if Victoria is posed with an extreme bend in her abdomen; the cloth could bunch together and look rough. To eliminate this artificial look you can shrink the panels along her abdomen.
Weight: The Weight setting controls the weight of the selected panel.
Friction: Friction is a very powerful setting. When used correctly, it can be extremely helpful. Friction basically controls the “clinginess” of the cloth on the figure. The higher a friction setting, the more “clingy” the cloth will be.
Gravity: This option allows the user to set the value for the effect of gravity on the cloth. The value represents multiples of earth's gravity.
Cloth Wind: Adding a wind direction simulates the effect of wind blowing the cloth. A wind node acts similar to a Directional light, in that the wind force is global across the entire scene in the direction indicated within the parameters tab.
To add a wind direction, click “Add Wind Direction”.
Go to the scene tab and select the node, Wind.
Finally, under the parameters tab, you will find a Velocity Slider.
Self Intersection: Self Intersection controls whether or not the cloth will be allowed to self intersect with itself or not.
|NOTE: We recommend that Self-Intersection be turned off during all your primary draping actions as best results are often found by turning on self-collision after a near final draped position has already been calculated. Results will vary, though, so feel free to experiment with this as you see fit.|
Collision Tolerance: Collision Tolerance is the tolerance, or distance fro the surface used when collision is being detected. This is an extremely useful tool when using multiple layers. For example, if you wanted to drape the Gaucho Jacket over the Ultimate T, you could increase the Collision Tolerance on the Gaucho jacket. Increasing the tolerance will make the cloth drape further from the figures surface.
|NOTE: When draping multiple clothing items in layers one above the other, it is important to also adjust the Collision Tolerance value of adjacent items.|
Internal Pressure: Internal Pressure can be used to have the clothing appear as if there was a volume pressure inside the clothing affecting it. For instance, the higher the Internal Pressure value, the more the clothing item acts as if it was filling up with air from within.
Animation Cache Path: The Path name of the folder where the animation cache data will be saved.
Multi-Item Drape Mode: When multiple Dynamic Cloth items are in the scene, the user has a choice of two different simulation settings.
|NOTE: We recommend that the “Sequential” mode be used for simulating multiple articles of dynamic clothing.|
Time Step: Time Step is the period of time which is used as a “snapshot ” for simulating dynamic cloth.
Iterations: The number of Iterations used when draping the clothing. The more iterations enabled, the better the outcome of the drape, yet the longer the required calculation time.
Animation Sub-frames: The number of steps between frames used when simulating animated cloth. Generally, the higher the sub-frame count, the more accurate the simulation will be, though a longer simulation time is required.
|NOTE: For most animations, it is recommended that animation sub-frames be a value between 4-24, but feel free to experiment with this for your specific scene needs.|
When working with a combination of props and figures that interact with each other, it can be helpful to animate static objects in non-traditional manners. For instance, if you wanted to have Victoria sitting on the floor in a room and simulate her pants properly around both her and the floor plane, you'll get better results in not only animating Victoria into her sitting position, but also animating (translating) the floor plane up underneath Victoria 4 to the final desired position. Having the simulation start with Victoria 4 already in position near the floor plane will often result in the dynamic clothing partially through the floor, which causes problems with the collision calculations.
