<![CDATA[[ANSWERED] Why GLSL Shader with input always shows error?]]>Hey guys,

My first day using GLSL Shader Actor, i followed the tutorial and find a nice shader here ← in Shadertoy

but everytime i pasted it in isadora it shows error which i really have no idea what's wrong

and i found that only the shaders with input would show this syntax error especially with music input

how do i fix this? and if it's possible to make a sound-interactive shader in isadora?

thx!

 One of the reasons I haven't learned to write my own yet :)

@woland but if i want to interact with that GLSL shader I have to change those code right?

Certainly possible, yes. I'd use Sound-Level Watcher actors fed through Limit-Scale-Value actors set to a specific scale to control input parameters on a GLSL shader. Sound input > Change in GLSL Shader parameters > Change in video output.

Not all GLSL Shaders are plug-and-play ready with Isadora.
