> Subject: [JAVA3D] how to set transparency of BranchGroup
>
> <<File: Josh Richmond.vcf.txt>>
> Hi,
>
> In my application, I'd like to load an .obj file and set the transparency
> value for all the geometry. I see that transparency can be set on Shape3D
> objects, but the obj file loader returns only a BranchGroup.
>
> Is there an easy way to set transparency for a BranchGroup such that all
> its children are affected?
>
> I tried BranchGroup.getAllChildren(), but when I query the list produced,
> there is only one Shape3D object; setting its transparency did not seem to
> work.
>
> I appreciate any help you can give me.

> Thanks!
