Hi I wander whether anyone can help?
I am trying to adapt the gradient material to suit my needs.
I am using it simply to control a rgb dmx fixture to change color over time.
I needed more colors than the 5 offered by default and have managed in the code editor to add more colors (I needed 7)
What I am unsure of is how the variable "speed" works.
I would like to be able to define the amount of time that each colour last for. So for instance 10 secs per gradient colour at the moment I am adjusting the speed value in the move menu by trial and error and using a stop watch but it would be preferable to understand what the numbers mean!

You can use the "TIME" global uniform. This is the time in seconds since application started.
The "mat_anim1" in Gradient is a generated "animator", it generates actually a "sawtooth" signal. You could also use a timebase if you want a growing value. Check in menu Help / Materials & Surface FX / Materials Documentation.
