I HATE piping! it always explodes in Marvelous Designer.

There are various reasons why Marvelous Designer piping might be misbehaving.

Reason 1: The fabric physical property settings applied to the piping are wrong and are causing it to explode, rise up into the air, "pop" up and down etc. (This is the most common reason for piping issues in Marvelous Designer).
So for instance, if you're running piping lines along the edges of clothes but the fabric property settings are too stiff, the piping will not drape well with the clothes. It will cause the clothes to rise up strangely as in the image below:

Instead of like this:

Reason 2: Your Marvelous Designer piping lines are overlapping.

Reason 3: Your piping lines are made in a wrong place on your clothes (for example: piping is made between patterns which are sewn together, under parts of patterns, and therefore the piping has a hard time to simulate with the clothes).

Reason 4: Marvelous Designer is having a bad bug day (nothing personal).

To solve most Marvelous Designer piping issues, try the following:
1. Make sure your piping lines are NOT overlapping!
2. Change the fabric physical properties applied to the piping lines. (If you don't want the piping to interfere with the way your clothes drape, try a very soft preset. If your piping is rising up or reacting like a stiff wire, change the fabric property settings).

3. "Refresh" the piping lines. Often does the trick and cleans up "messy" "lumpy" piping lines.

4. Delete the piping line and redo the piping.
5. If this is only happening in one project, it may be an MD bug.
Delete piping, close MD, reopen it, and try to create the piping again.
6. If this Marvelous Designer piping issue is occurring after upgrading MD software, it may be an MD upgrade bug. Report a bug to MD developers.

Hope that helps! 🙂

@camille-kleinman refresh piping always does the trick for me.

@camille kleinman thank you so much!!! that was the issue. I changed property to silk and now it works!  😀
