i think you might need to explicitly add an image plane called “indirect_emission”. it's not a “standard” lighting tag that works via the export planes option.

fwiw, when you do a pcopen() in vex, the points are ordered from closest to farthest. also, if you simply restrict your pcopen() to a single point, it will be the one that's closest to your search point.

in a point wrangle:


if (f@burned>0)
removepoint(0,i@ptnum);

hmm… yeah, the wording seems to have changed on the london event:

“Side Effects Software, in partnership with Escape Studios, owned by Pearson College, invites you join us for the official launch of Houdini 15 on October 5th!”

now it says:

“Side Effects Software, in partnership with Escape Studios, a part of Pearson College London, invites you join us for a sneak peek at Houdini 15 this coming October 5th in London, UK”
