In this case,
How to edit SHOP in VEX Builder?

I created the .vfl file by right-clicking the OUTPUT
of the surface shader, selected save code.
I have used vcc command to create the .vex and .ds file,
moved the .ds file the shop/surface,
modified shopsurface file by adding
“v_NAME shop/surface/NAME.ds -label ?gVEX_NAME?h,
then can use it in SHOP well.
But can't edit the SHOP.
Right-click the SHOP icon, can't select ”Edit VEX network".
Thank you.

You would save yourself a lot of grief if you avoided the old method of manually compiling code and let Houdini manage all that for you. When you're in a VEX shader network, right-click on any of the VOPs and you'll see “Create New Shop” - select that and you have a SHOP auto-magically created for you, and it will dynamically update with parameters as you alter them in your vopnet. You can also righlt-click on the SHOP anytime and “Edit VOP Network”.

You'll never have to manage those horrible ds files again!

Oh, by the way - be careful *not* to select “Create New SHOP Type”! That's a different beast. You may want to use this in the future, but it's not the same thing. I've always felt they were too similarly named, but then again I can't come up with a better name.

Thank you.
There are not many tutorial of VEX Builder in the web.
I downloaded some .vfl, .vex and .ds files from the web,
and the many Houdini's default SHOPs have the .vfl and .vex file,
I want to make a study at that in VEX Builder.
Thank you for the informations.
