File Input and Combiner Dont play well together

Hey,
Im new to WM. I have a simple height map that I have imported and would like combine it with layout that I have generated in WM. It sounds simple but when i link the file input to a combiner or chooser, whatever comes after the chooser becomes disabled. My connecting lines become dotted and grayed out. Is there something im missing or is there a workout around? Thanks

Hi Train,

Take a look at the status indicator for the Combiner/Chooser – is it red or yellow? If it’s red, you haven’t fully connected the device to be able to produce output.

A Combiner takes two inputs and combines them somehow.

A Chooser takes 3 inputs, and chooses between the first two based upon the 3rd.

Hey,
Its working. Thats great. Seems so simple, I though i had it all linked up before but i guess not. Alls well that ends well. Thanks
