Houdini multiple ASS scatter

Hey,

I'm trying to get some basic .ASS scatters going using the attribute wrangle method:

I've been looking around but can't seem to find any info on how to scatter multiple .ASS files, opposed to a single path.

I'm sure it's something simple like an additional bit of VEX to randomize the path selection. Though I'm not a Houdini artist by trade, therefore working this stuff out is a little slow at the moment.

Anyone know the best way to hook up this up using the method mentioned above?

Cheers,

If you have four ass files example1, example2, example3, example4, then you can get a random ass file by setting instancefile like this:


`int(1 + 4 * rand($PT+48249))`.ass


48249 is just some number

Something like:


h_box_00`int(1 + 2 * rand($PT+48249))`.ass


You can use the Geometry spreadsheet to check the values.

Sorry, I missed this.
It worked though, thanks 🙂
