Tiling Issue with Rebelway technique 2021年10月3日22:54

If you watch that section of the course it should be clear what's goin on. What's interesting is if I put a fit node after the bind (rest) node and change the Source Min value to -1, -1, -1 and re-render the tiling trick seems to work. But, what I don't understand is how Saber was able to make it work without the fit. I guess, I'm just wondering if SideFX changed something that affected this functionality between that older version of Houdini and 18.5.

Tiling Issue with Rebelway technique 2021年10月1日16:10

I've been working my way through the free Rebelway asset creation courses [] and the same tiling method is being used in both of the first two parts for COPs and VOPs tiling. However, I ran into a snag around 4:27:00 of the first masterclass, where Saber bakes out the flattened Torus to assist in tiling the texture. Perhaps, I did something wrong when rendering it out of Mantra, but my rendered texture looks correct, and I'm getting some bizarre banding when trying to implement it in the Tiling Part 2 section as well as the tiling section of the second VOPs course even though I seem to have everything hooked up properly. I posted this question in the YouTube discussion, but no response and it seems like someone else posted the same issue on there already. In any case, I wrote Rebelway to ask if they still had the assets, which they don't and informed me that the course was discontinued because they need to update it for use with the latest version of Houdini. So, I'm wondering if it's possible that SideFX changed something under the hood in Houdini 18.5 that's messing with this workflow, or am I just improperly baking out the texture?

VDBs & standard light display issue in viewport 2021年10月1日16:00

This is more of a minor annoyance than anything else, but I'm working through part 3 of this free Rebelway asset creation course []
and around 9:30 I noticed a different behavior than in the video when trying to shade a VDB fog in the viewport with standard distant lights. It seems like the light gets cut off at the surface of the volume, and as far as I can tell it's not caused by the Arnold lights or anything else in the scene. The set up is super basic, and the same thing happens when building the scene from scratch in new projects. That said, it would be nice to have lights interacting properly with the fog, so I thought I'd ask to see if anyone has any idea what might be causing that. I know that this masterclass was created in a much older version of Houdini, perhaps as early as 16.5, so I imagine it might be a version difference, but it seems like a silly behavior to change. Might it be a bug? It still happens after updating Houdini...
