For test images and the user's command from Windows, see viewtopic.php?f=3&t=29582#p132839. I have fixed some issues there with his command and tested them below. I would not have used composite, but would have made this one long convert command without the pipes. But I tested it for him and found this issue.

I did these three tests:

This works fine with IM 6.9.3.9 (convert, then composite, then convert again):
This works fine with IM 7.0.1.0 and convert in two places (convert, then composite, then convert):

This works fine with IM 7.0.1.0 and magick and convert mixed (magick, then composite, then convert):

This fails with IM 7.0.1.0 magick only (magick, then composite, then magick):
-bash: magick: command not found

The command finishes, but no output is produced.

Apparently, IM 7 does not like to pipe from composite back to magick.

Your command works for us without complaint:

• magick Tx_Sky_Overcast.dds -resize 4096x4096 -background "rgb(6,8,10)" -alpha remove miff:- | composite -compose over Tx_Skd_CloudBreak_Mask.dds - -alpha set miff:- | magick Tx_Skd_4xCloudy.dds - -composite -define dds:compression=dxt5 -define dds:cluster-fit=false Tx_Sky_Overcast_7010magick2.dds

We're using ImageMagick 7.0.1-1 under Fedora Linux.

Strange! Perhaps only on Mac OSX? Can anyone else duplicate the failure and error message?

Never mind. It was my mistake. I am using IM 7 via my im7 script from make, but not make install, so I can run many versions of IM on my Mac. I forgot to preface each part of the command with im7, so I was getting a mixed IM 6 and IM 7 result.
