Custom VRChat shader, good and bad


So, today I had a great idea for making a custom shader for my VRChat avatar which would make it much easier for me to generate color schemes for my avatar. I called the technique a “Pigment Map,” for lack of a better term; basically I used the four channels of a texture as fuzzy “bits” in a palette lookup, and set things up cleverly so that I could modulate between a bunch of different colors based on surface pigmentation and indirect lookup thereof. The idea is that I wouldn’t need to bake out a bunch of textures for, say, red-and-black plaid, purple plaid, green plaid, etc., and could just have mappings for high-level colorations like plaid, stripes, splotches, and so on. Y'know, as one does.

Some VRChat avatar creaton tips, so far


I’ve been working on a critter avatar for VRChat, as mentioned previously. It’s been an interesting process, with a bunch of elation mixed with a whole lot of frustration.

Someday I’ll write up a collected thing with a bunch of what I’ve learned, but here’s some salient things before I forget.

GERDing my loins


I used to have pretty bad issues with GERD back in the day, which I ended up successfully treating through a change in diet and habits, namely not eating after 9 PM and pretty much eliminating mint from my diet (aside from the occasional treat). But lately I’ve been having GERD issues again, and for the past few days in particular have been waking up in the middle of the night with acid in my throat and, often, rather loud noises of bubbling through my body, which I assume are peristalsis with gas bubbles or something.

This has been pretty badly affecting my sleep and making my fatigue way, way worse than usual. Ugh.

Critter avatar progress


I hadn’t made much progress on my avatar, as mentioned previously, because I wasn’t feeling all that up on building stuff for VRChat for a number of reasons. But I’ve finally gotten the urge to start working on it again, and I’ve made quite a bit of progress.

The main thing is over the past day or so I’ve set up all of the visemes and some useful configuration shapekeys1 (namely being able to adjust the torso configuration), and have also looked at some plugins that will supposedly make my life easier. In particular, my friend Lagos pointed me to Cat’s Blender Plugin which seems to provide some very nice improvements to the VRChat avatar creation workflow.

I’m at a point where I think the next steps are rigging and UVing, and those require destructively applying my mesh modifiers, which is a point of no return. I think the Cat’s Plugin workflow is set up such that instead of doing that to my base model, I’m supposed to export it as a .fbx and then reimport it into a new project (or as a new object in the same project, I suppose) and then do the next steps from there. Which makes some amount of sense.

Falsehoods programmers believe about “Falsehoods programmers believe about” lists

  • These lists are intended to be exhaustive
  • Every item on the list applies to every situation
  • Every item on the list must be taken to heart and considered at all times
  • Every item based in historical fact is worth worrying about for all future implementations
  • Every item deserves explanation
  • An assumption you made that shows up on the list is a personal attack on your programming abilities
  • These lists are intended as guides for how to do things (or, conversely, guides for things not to do)

Lack of VRChat build progress


Recently a couple of folks have asked me if I’ve made any progress on my VRChat avatar, and no, I haven’t. There’s a bunch of reasons for that, but a big one is that I just don’t really feel like the amount of time/energy it’d take is worth it in the end.

In particular, VRChat’s avatar system requires a lot of fiddly work to go into it, and a lot of very hyper-domain-specific knowledge, because a lot of things in VRC are very shoddy hacks on top of the “expression” system which was clearly built for entirely different purposes than what it’s being used for.

The more I work on modifying the Winterpaw mouse for my needs, the more I learn about just how… weird VRC is, and given that the future of the platform itself is easy to doubt, I’d rather focus on building stuff that’s a bit more transferable between systems. So for now I’m just modifying the mouse.

Commissions open


I like Ko-Fi. They started out as a nice, friendly tip jar system, and they’ve only gotten better over time. They’ve done exactly what I keep saying companies should do: build a useful, sustainable business that makes a good income for all concerned parties. They haven’t gotten on a VC-backed treadmill of unsustainable growth, they haven’t made moves to “maximize engagement” or check off all the boxes for dystopian hyper-capitalism, and they haven’t gotten into a vicious cycle of worker exploitation.

Ko-Fi just started out as a tip jar, but then they added monthly memberships (á la Patreon) and asset/object sales (like Gumroad and Etsy). And now they’ve added their answer to Fiverr and Upwork: commissions.

So anyway my commissions are open. I’m just focusing on music for now but I might add more things over time.

Kitchen stuff


While cooking dinner tonight I got a surprising electrical shock off of the handle of one of my pots, which was sitting on a burner which was on but was weirdly not getting hot. So, there’s clearly some awful short circuit in my stove. So it’s time to replace that.

As usual I’ve been wanting an induction stove anyway, but I was hoping to hold off until I could properly redo my kitchen. I sort of had the idea that I’d be reconfiguring it to have a built-in oven and a smaller cooktop in order to have more prep space, since my kitchen is pretty tiny. But I guess it isn’t the worst thing to upgrade the stove before everything else, right?

More importantly, I was hoping to hold off until my condo sold and I had, y'know, plenty of money for this. All the induction ranges I’m interested in cost considerably more than I feel comfortable paying right now. Although there’s one Samsung model that I like and is fairly affordable, but also it has about a 6-week wait right now.

It seems like it’s only one burner that’s shorting out, but that’s one too many for my comfort.

I’m sure I could tear the stove down and find where the electrical fault is, but, jeeze, I’m not all that interested in messing with 240V stuff.

Update: Home Depot had the Samsung in stock and ready for delivery/installation August 10, so I just went ahead and ordered it. Ugh.

Update 2: Oh right August 10 is a busy day for me, I should see if I can reschedule it to the 11th

Update 3: It is rescheduled, yay. Home Depot works, sometimes.
