Vop Network With No Input??

Recommended Posts

Hi everyone,

I'm going through the Building Procedural Cities DVD (from cmivfx) and I've been trying to do everything exactly like was done in the video... but when I went into the COP section (sorry, I'm a newbie, I know there's a more appropriate word for it), my VOP network didn't have an input :/

I'm attaching a picture of my problem (no input) and my network. I feel like it's something I missed, but I'd really like to know what I did wrong.

thanks...

Also, make sure you have the min, max # of inputs set to 1 and 2 (for the mask) in the VOP Filter node. All filters have an optional mask input.

Make sure to use a filter vop and not a generator one.

Ahhh... that was it! thanks!

I went back and watched the video again and he even said exactly what you just said. I guess I just missed it trying to follow along.

thanks for the help, guys...
