Accessing Point Attributes in SHOP

[phong]

Hi! I was just wondering how I can access custom point attributes in SHOP?

Get Point Attribute gives me strange results and so does PointAttribute.

Any ideas?

Thanks,

Nhat

I assume this is in a Material shader builder SHOP.

Create a "bind" VOP, name it the same as your attribute and set the data type to match as well.

Yes this is in a material shader builder SHOP. Where would I find the bind VOP? Didn't show up in the material builder.

Thanks for helping Jon!

You have to bee inside your material, or vop-network in orther to create a bind-node

Hi thanks for replying!

The bind node shows up as an "Add" node called "Bind1" in my mantrasurface node and is in error state.

Am I running a too old Houdini version (12.0.543.9)?

Try Parameter VOP on 12.0 instead.

Tried that, but it takes whatever default value is set there.

Or do I have to write a short little VEX code to gather the vertex attributes?

Hey.

Check the file, if you hit render you can see it's working. You just have to name your parameter properly (matching attribute name) and set correct data type (float, vector).
