[HDA] FFX Geometry Explainer May 15, 2023, 1:29 p.m.

FFX Geometry Explainer is an assistive HDA for Educators, and DIY learners. As a beginner, have you struggled with understanding how Vertex, Point, Primitive, Detail, UV Seam, Edges, Half-Edges, Normals, Normal winding, and Shared/Unshared points relate in Houdini? This HDA should help.

For Educators, there is an unlocked option, so you can dive into the tool build and customize it to your specific needs if you like.

For learners, there's a cheaper basic version that is locked, but has all the same learning info.

10000% agree. A completely new marketplace rebuild is needed. My current experience when launching FFX Collection was an absolute debacle. Gumroad is the best distribution platform (IMO at the moment) for stuff like this. Plus allows for setting up discounts, giveaways, and sales occasionally.

Things I ran into with my last launch.

  • The HDA conversion process from one tier to all others does not include anything under "Extra Files" of the HDA. So licensing can carry through and break HDA. This happened with FFX Collection as the Python files I built apparently kept the Indie licensing. I was unaware of this until Commercial users complained about session downgrades they were experiencing. Only solution (after weeks of no fix from Side Fx. Devs are aware of issue though) was for me to completely rebuild the HDA in a Commercial FX license to fix the issue.
  • There is inconsistent information when uploading versus FAQ (image size recommendations differ).
  • Broken markup language in HDA description area (randomly bold or italic markup characters bleed through to the final post). I kinda half expect this list to be broken when I click submit.
  • Payout info is vague at best (you have to dig to then finally find net60 as rule), and still no mention of how it's paid or W9.
  • The review process is wildly inconsistent. I get Big convention events closes the company practically, but 24hr-120hr possible range of time before post goes live, makes announcing an product release extremely difficult.
