  1. I'm really trying to learn VEX so anything that gets thrown my way helps. Thanks so much!
  2. Tomas. You're amazing. Thank you sooo much for taking the time to do all this. I can't emphasize how much I appreciate it. Just so awesome.
  3. Yeah, I'm in H14. Ok, so I apologize in advance for my stupidity. So here's what I have but it basically just spits out a matrix. I'd ideally like a for loop within a for loop, if that makes any sense. Or is there a way to store/reference the original split string array without splitting the group array? string ptGrps[] = detailintrinsic(0, "pointgroups"); s[]@ptinGrps = {}; foreach(string grp;ptGrps){ if (inpointgroup(0, grp, @ptnum)) append(s[]@ptinGrps, grp); split(s[]@ptinGrps, grp, "_"); } s[]@indexAttr = {}; foreach(int i; string s; ptGrps){ s@indexAttr = @ptinGrps[1]; } /* String to Int string indexString[] = {}; foreach(int i; string s; indexString){ i@objectID = atoi(s); } */ Group_ID_Array_01.hipnc
  4. Thanks for the quick reply! Big fan of your blog posts. Yeah, it certainly isn't an ideal setup but I'm working from a cache; so it's a bit wonky from the start. I had no idea there was a name node, that's awesome. Thanks for that bit. The point group array setup is super helpful too. I'm just stuck on the opdigits part though. From within the Point Wrangle node, opdigits isn't a recognized function...? Would you apply it from another node?
  5. Ok, I have many objects separated into point groups by unique suffixes. I'd like to split the suffix integer value from the array of group names. Then assign that integer to a custom attribute. I'm terrible at VEX so any suggestions would be greatly appreciated.
  6. Attribute to influence Arnold SHOP context

  7. Hello! I have a question for what I thought would be fairly simple to figure out. I'm trying to use an attribute from a per point object level to influence the emission strength of my Arnold material. I'd usually just use a bind node, but that option isn't available in Arnold. Anyone know the HtoA equivalent? Thanks in advance for any tips.
