Whitelist Constraints

in progress

akalink

Constraints have been a staple of PC since the 2018 update. Having constraints would be a great asset to Quest creators as it can allow for similariton of various pc only components such as dynamic bones and final ik.

StormiTheAvali: To be very succinct, contrary to previous belief constraints aren't free, especially at the levels some avatars utilize them (50+).
They have a performance cost which gets to significant levels, especially in a heavily CPU-constrained environment like the Quest-- even if the number of constraints used is quite low.
We've got some alternate solutions we're thinking of, but this isn't in active development yet.

We're working on a new component for the VRChat Avatars SDK!

This component will be very similar to Unity's constraints - but it will work on on Quest 🎉
We won't be whitelisting constraints directly
, but we hope you'll enjoy the ability to use constraints on Quest.

Fax Very interesting. Looking forward to it

Fax Thank you so much. It's really gonna improve quality life of creators who sometimes cannot convert their assets because constraints are essential to its functions. ♥

Fax super excited to make fun things like head squishes on quest!!

Any update on this?

so i was trying to make a grabble prop for my avi for quest how tf do i do it? if it involves Parent Constraints im friked

Though I understand constraints aren't free, they don't need to be unlimited. You don't technically need ANY constraints if you properly put objects in the armature, but we need ONE constraint to achieve world space

I'd really like constraints to be a thing, I need them to get digitigrade legs working with vrchats plantigrade leg-based animations.

I can see it isn't possible on Quest atm, and I hope a solution of any sort comes around soon. :(

Some of my avatars use Rotation Constraints for the legs to preserve full body tracking movement without legs going through the floor sometimes, This is incredibly useful and my quest friends cannot see it, and it really sucks.

I wish Quest wasn't so limited when it came to constraints. All i want to do is copy rotation between a few bones, that is all.

Constraints Quest Compatible

Quest currently isn't able to have constraints on avatars. I feel this should be something that should be added to quest its not to hard to run and I think it would be a fun tool to add for avatars.

I have precisely 12 multiple legged avatars that would work perfectly on quest but don't due to this limitation, please add it, I love you pleas add this.

JuicedPotato

Mmmmmm, yeah - got a bunch of avatars I have to either entirely redesign or abandon for Quest due to no constraints.

Some with grabbable objects which are less optimised (can't re-parent the object bones, have to have duplicates which are shown/hidden), some with multiple limb sets or extra bones (my main avatar has Digitagrade legs) which can't be done at all.

Xan

I actively use constraints for a number of my avatars so that they can have multiple limbs of the same type (like four arms), or joints that are otherwise impossible to achieve on a humanoid rig (for example, a trick involving a very long thigh bone to achieve the illusion of functional digitigrade legs).

Doing these various tricks

requires

the use of constraints, rendering these avatars completely unable to be ported to the Quest without compromising the appearance. This is less than ideal as a lot of my avatars are designed with Quest compatibility in mind, or those that I purchase are modified such that they are Quest compatible after I upload them.
