Problem:

How do I get a nice mapping with my fixtures in LED Mapper?

Solution:

A workflow that is used by some light designer is to create a mapping background in photoshop.
By example if you need to map a few bar you create a visual such as this one

The size should be as small as possible depending your fixtures, here it's in 64 by 64.
You must also use that in the LED Mapper:

You can then import your visual

You will see that in the canvas

You can then place your bars in the canvas

You can now rework the background picture you loaded in the LED Mapper with photoshop and changed the color as you want.
Once you created a few pictures you can load them in the MediaMaster library and map them in the theater mode by example

We have color rotation effects that should give nice results when mapped over LEDs.
