Find attribute in ForEach Loop

[plazadelmar]

I can't see my attribute when using the "detail" path to the ForEach node. How can I transfer the attribute to the Transform node?

You have two problems. One is that the attribute you are trying to reference does not exist in the detail context, it exists on the points context. The other problem is you are trying to fetch the value from input 0. Input 0 of the transform node would be box1, not the FOREACH_BEGIN. When using hScript functions to fetch data, you almost always have to provide the explicit path to the node where you are fetching the data. 

While you can use an expression to drive a transform, there is no need, that is what f@pscale is used for.

point("../foreach_begin1/",0,"myDist",0)

 

 

Here is the scene implemented using f@pscale instead, with the transform disabled. They look the same.

Thank you, I can see now several ways to solve it. Pscale is probably the simplest and cleanest, to keep the detail attribute you could promote it from point to detail.
