Hi,

I am trying to modify layer values in a heightfield, but do not know the layer names up front. I get the names via the @name prim attribute. I would love to be able to use the @ syntax to set values in the layers from a derived layer name.

Setting @Derived_string_for_Layer = value obviously does not work. Is there a syntax I am unaware of to make this work?

Secondly using setpointattrib() which would allow me to work with derived attrib names in an attribute wrangle, does not work with HF from what I can see. Maybe I am just not using it correctly in HF wrangle. Could someone post an example that does work in HF wrangle? Or suggest best method to approach this type of issue when working with HF's. I would like to avoid OpenCL based kernel solution if possible.

Thanks,
R.

does this work for you?

As for setpointattrib(), although volume vop evaluates in same cvex context as attrib vop, functions that modify geometry will only work in an attrib vop, as the volume vop is exclusively for binding to volumes.

@jsmack - thx for the reply

I am trying to do this essentially


A colleague suggested using the HF wrangle bindings tab, to autobind the @name values inadvance.
I will pursue that approach for the time being.

Would be nice to get equivalent of setpointattrib() for HeightFields.

Thanks,
R.

Do you have an example of this? I started using volume wrangle for heightfields and I'm lost. I can play around with @mask and @height but I can't create my own @myHeight. Would the binding tab solve this? …if so, how do I use it? I'm clueless…

Thanks.
