not sure where to ask this, but is there are way to have a brush that's basically a square alpha? ideally it keeps it's thickness from start to end and essentially a stroke is a long 3d rectangle (obviously taking the trajectory of the motion)

I think you can approximate that that using plugins, but it seems plausible for a custom brush too.

how do you import or customize brushes? i’m only familiar with the built-in brushes in the openbrush app on the meta quest.

I don't think I understand what you're asking precisely. There are several brushes with square or rectangular cross-sections. Square flat? Do you basically want that but less rectangular in cross section? Also not sure what you mean by the word "alpha" in this context?

Plugins can't change brush shapes in this way.

Correct - custom brushes aren't currently supported (without running a custom build)

I was thinking you could cheat by using a bunch of smaller brushes arranged as a rectangle, guess I should have made that explicit

Not a bad idea - would probably be possible as a Symmetry plugin. But I'm still curious what exactly @nufsenk wants. There's a few brushes that do something similar already so I might be misunderstanding something.

right, that’s what i had understood, thanks

essentially, a “cube-strip”

fo example like this https://cdn.discordapp.com/attachments/783806589991780415/1554154625467285644/kneecap_001.png?ex=6abbdac9&is=6aba8949&hm=42357aa094dec86a0c6a201d99a36d2bf0454f02b7ac3e9e96e7aed700c9a432&

these are leg bones i sculpted in gravity sketch, but i'd rather use openbrush (various different reasons). the way i did it is by creating a brush that is essentially an endlessly extruded cube, that never changes in thickness (unless scaled obviously). if you zoom in on the image, you can see how the bones are composed of lots of cube strips. it's my version between painting, traditional sculpture and building meshes with primitives. it gives me an expressive base to sculpt further in other software.

i really wish i could do this cube strip thing in openbrush so i could never touch gravitysketch again 😛

have you tried open blocks? it has better poly modelling than open brush

however i don't quite see how you'd do this in either app -how about the texture mapping?

i guess i don't really understand your workflow

it’s on my list: i’ve only installed it and opened it once to see but i need to play around with it 🙂‍↕️

yeah, it’s a bit unorthodox tbh

i’ll experiment further, fanx for the help!

I would use modeler or ShapeLab for this. They also can export your object with proper topology, normals etc.

Basically that seems like a combination of a thin extruded rectangle to draw the strips and clusters of shorter ones to make up the bone knots. So what you'd probably need to efficiently replicate that is a strip that tapers with velocity or by applying the thumbstick or trigger strength. It might be designed to widen and flatetten at the same time. This is probably quite a bit more complicated but would give better control of the width changes. Curvature would flow along the actual draw line. In constructive term, the bone you've designed is more or less a stack fo tendons, which would also be useful for doing things like irregular tree bark. It would be pretty processing heavy as far as brushes go, I'd think. The knots themselves might be doable with two or three irregular semispheres, like a dome shape using the same texture or some form of boolean join (also processor heavy) but probably doable with a decent PC attached. I'm intersted in this, as I enjoy anatomy and have been thinking about how to approach this. Really like the work you did there

fanx, i appreciate it 🙂 and for taking the time to reply! but yeah not sure how to get it done, but that's ok, my workflow's ok for now. i'm mainly getting creative with the limitations of what is still a very young medium (vr).

@nufsenk for sculpting, I tried gravity sketch and Medium by Adobe. The last one is essentially clay modeling. There are different export options

i tried them all, gravity’s the only one that has the specific feature i use, but i just don’t like everything else about gravity 😂 and wanted to have this in openbrush instead

Looking at bone mesh - I can't think what Open Brush feature would get you there. We can have brush strokes with rectangular cross-sections but that mesh has very specific geometry and texture maps.

So - I'm probably misunderstanding what you're aiming for

how do you get a brush with a rectangular cross-section? do you know of a way to do this in the meta quest app, or would i need to use the desktop version?

Its the 3d print brush or the square flat. They might be part of the advanced brush set. Should be available in the headset as long as you arent in beginner mode.

you also need to turn on "experimental brushes" in the settings panel

it might be time to make this the default setting 🤔
