Hey, Brian. I want to thank you for your tutorial.  It took me a long time since I am still a beginner, but I was ultimately successful.  It gives me confidence for my next project.  Anyway, thanks.

Thanks Brian!  I'll check the inputs coming in, great tutorials

Orange components mean there is incomplete data coming in. Check the inputs to make sure you have the expected data entering the component. Post what you have so far here as well and I'll take a look.

Hi Brian

When I paste and copy the srf cp and the eval srf, and connect it to the cull index, the connections are orange, what'w wrong?

Thanks so much Brian. it works! :)

Hi Maryam, You can use the Dir command to see the current curve direction and then use the Flip option in the command line to reverse it or You can just run the Flip command on the curve you want to reverse.
