– Info regarding License Keys

By default, users are given one ‘1’ license key for each copy of Cloth Weaver purchased. Cloth Weaver can be installed on multiple computers, but only X quantity of copies can run simultaneously. More copies can always be purchased later; license keys will be given for each extra copy purchased.


Cloth Weaver automatically ‘de-activates’ the copy when it is closed, allowing users to easily migrate to another computer. If a running copy crashes and does not shutdown properly, the license key will be reset after 2 minutes and users will be able to launch another copy of Cloth Weaver. Users can also use Cloth Weaver in Offline Mode which does not require an internet connection. Keep in mind, this copy’s license key will remain ‘active’ until you manually de-activate it by clicking ‘Switch to Online Mode’.


Example: John has 1 copy for his license key. He can install Cloth Weaver on his desktop and laptop. However, only 1 copy can run at a time. John has finished creating on his desktop and wants to take his project on the go. He closes his running copy of Cloth Weaver and it automatically de-activates. Now John is able to open Cloth Weaver on his laptop

Working with Clothing | Rigging

– How do I keep the clothing from falling off my character?

It is best to “pin” some vertices in the cloth sim panel so they won’t be affected by gravity. Select your clothing, enter edit mode, in Blender’s data panel, create a new vertex group and the area you don’t want the sim to influence. For example: Top of a skirt, collar of a shirt, cuffs of a sleeve, etc.

– Clothing is hovering above the character?

The collision on the character needs to be closer to the skin. On the character’s collision, change the outer to 0.005 or 0.001.

– Cloth shrivels, passes through character?

Remember: When attaching clothing, it is a trial and error process. Do not expect it to be exact the first time. Please refer to our tutorials. Try moving the top of the clothing slightly higher above the arms and shoulders. This is the usual area of issue. It will also help to add more ring/loops horizontally in the arm areas. This should close that gap. You could also move the highest shoulder areas closer together. Again, it is a bit of trail and error. You can delete the current model after sewing and restore the backup. This will keep the specific modifiers in-tact. Sometimes, undo-ing may have undesired effects.

– Clothing presets appear much bigger/smaller than my character.

If the clothing is too big or small, scale it down or up to match your character. If the character is smaller than one square on the Blender’s default grid floor, then the character’s scale will need to be increased.

– Rigging problems ~Clothing or character pose is offset? ~Rest pose is different in edit mode?

~Rigging is offset when switching to edit mode?


Explanation: The above character’s default ‘resting pose’ is in an A-Pose. The character’s rig was put into a T-pose and then the clothing was applied to the rig. Because the character has already been posed before the clothing was attached, the clothing will now ‘offset’ and move the with it. As a general rule, anything applied to a rig will follow the ‘resting pose’. 


Solution: Select the character, apply the rig modifier. Then select the rig in pose-mode, press space-bar and search for “apply pose as rest pose”. Parent character to the rig and then clothing to the rig.

– Must the figure be in a T-pose? Will the plug-in be able to handle A or Star poses?

The clothing templates are designed to best work with T-poses. However, if the clothing is adjusted to your specific pose before hand, yes any pose should work. Make sure to read the above post regarding “Rigging Problems” for more info.

– UV mapping is incorrect when exporting to other 3D platforms (sketchfab, unreal, unity)

Select the clothing in Blender, go to the data panel and make sure the selected UV map is the one you want exported. When unwrapping each section (patterns, bump map, grunge), make sure you have the correct UV map also selected.

Error messages
