westiemad Posted September 11, 2008 Share Posted September 11, 2008 Afternoon Gents, I have a problem with using a switch node in COPs, if you create a color, and a file (using the default pic), then connect them into the switch, all is well, but if you try to drive the Input index of the switch with an if statement like: if($F == 1, 0 ,1) i get an error "an input could not be evaluated". I tried in 8.2 and 9.1, so I think it must be me. Any clues? Cheers Guys Quote Link to comment Share on other sites More sharing options...
malexander Posted September 11, 2008 Share Posted September 11, 2008 If you animate the switch, all the inputs must match in resolution, data format and frame range exactly. If it's not possible to get them set up like that, you can use a Blend COP instead with an integer expression. Newer Houdini builds have a more clear error message.

Thanks for the info, I thought it might be something like that, I think the blend COP is a better idea. AnDy Quote Link to comment Share on other sites More sharing options...
