meta loop VOPs
Thursday, 24 February 2005 Thu, 24 Feb '05
Hey all. Could anyone explain to me how I should go about using the meta-loop VOPs? I've tried running P into pos on metastart, then handle into metanext. From there I take bool into the initial condition of a while loop that goes back and forth between summing the density from metaimport and iterating through metanext, with the bail set to metanext's conditional. It seems, however, that the metanext op before the loop returns 0, meaning I don't get very into the metas at all. I don't think it's a problem with a bad/poorly referenced bgeo (pointcount works just find and there's definitely metageometry there). What I'm trying to do is envelope a surface in metas, then color the surface by the metas' density sum at the surface point. I looked through the archives, but the only discussion I found mentions using second input on metanext, which I don't have (houdini 6). Any help is much appreciated. -Sean
