How to get help with this particular shader
Sadly, the custodians likely will not be able to explain to you how a shader works or debug its code, or fix it for you. That is the (volountary) role of the shader author.
If the shader does not work on your system or you have questions about it - read the shader description, and try to find the email address of the shader author. Contact them for any issues – letting them know whether you are on Mac or Linux, what version of IFFS you are running etc. will likely help. Be kind and respectful. If you can't get hold of the author - you can try asking in the Logik forum at logik.tv and ask whether anyone could help you debug a particular shader not working.
