Dear MadMapper Forum,

I am working on a project where I am using an ISF shader in conjunction with a DMX light in MadMapper. The ISF shader is successfully integrated and displays the desired visual pattern on the DMX light. My goal is to control the shader in a way that it stops after completing one cycle.

Specifically, I would like to specify a duration in seconds that indicates how long the shader takes to complete one cycle. After the shader has completed one cycle, it should stop and not continue playing.

My question to the community is: Is there a method to specify the duration in seconds and control the ISF shader to run once within this time frame and then stop?

I would greatly appreciate any advice or ideas that could help me achieve my goal.

Thank you in advance for your support!

Best regards,

Without modifying the code and adding a "generated" uniform in the shader to get the "elapsed" time since last "restart", you have to use cues to show / hide the surface with the ISF after some time. Either using "Auto Play" of the cue bank (you can set a duration on each column), or you can do more complex programming with the Cue Scheduler module. Check the "Scenes & Cues" user guide (available from menu Help)
