Why Dose It Take So Long to Upload a Model Into Vrchat

VRChat on Quest: Avatar Performance Woes

Or, "Why Is Anybody Gray Robots?"

If you use VRChat on the Oculus Quest, you have probably seen your fair share of the "grayness robots" — the generic placeholder avatar that VRChat uses in place of a user's avatar in various cases. Yous've probably also noticed that there are a lot of them.

Why am I seeing a gray robot?

There are ii principal reasons you'll see these placeholder "grayness robot" avatars: Very Poor operation rank avatars, and avatars without a Quest asset available.

When an avatar is ranked "Very Poor" on VRChat for Quest, it is hidden by default. It volition show as a gray robot with the text "Perf Blocked" on the chest, and you can't meet information technology until you lot click "Show Avatar" on each user you detect wearing 1. We do this to prevent performance issues on the Quest.

In addition, yous'll see more gray robots when you find someone using an avatar without a Quest version. These robots will testify upwards with the thumbnail image of the avatar on their breast. Clicking "Show Avatar" on them won't exercise annihilation. Think of information technology like trying to put a Blu-Ray disc into a DVD player — the actor has no idea what the information is.

Okay, but why are there so many gray robots?

Hmm, I wonder why?

The principal reason for placeholder avatars on Quest is the "Perf Blocked" reason. The vast majority of avatars used on the Quest version of VRChat are ranked as Very Poor, and therefore are hidden by default. Out of the Very Poor avatars on Quest, most of them exceed the limits by 10x or more. This indicates that many Quest avatar authors are not making any attempts to optimize at all, and are instead uploading avatars intended for PC usage.

There'south a few reasons for this. Making a "Good" or "Splendid" avatar on Quest is difficult. The limits are quite stringent. Nosotros need to make it easier to make avatars that fit within the limits — or re-evaluate the limits themselves.

Our goal is to accept as many avatars showing as possible. However, if we show many of these Very Poor ranked avatars at the same time, FPS drops, system memory fills upwards, and your performance tanks. In the worst cases, VRChat volition send you back to your Home or but crash outright.

The secondary reason behind "grey robots" is when an avatar hasn't been uploaded for Quest. This is a harder problem to solve.

Since substantially 100% of the content on VRChat is user-created, we're going to be taking some steps to mitigate both major causes of the "grey robot problem".

How is VRChat going to address Very Poor avatars on Quest?

Let's starting time with the "Perf Blocked" greyness robots. There'south a few pathways, but we're starting out wearisome. Here's our plan.

First, since the hardware mural has changed a bit (and later on some extensive benchmarking), we volition be increasing the limits for the Very Poor, Poor, Medium, Good, and Fantabulous Operation Ranks . This volition get in easier to create avatars that fall within the limits, and hopefully encourage authors to create optimized avatars. Initially nosotros will be increasing the limit on polygon count for Oculus Quest specifically.

Haven't seen eyebrows like that since Amarao

This is an guess doubling (plus a scrap more) of the previous limits for polygon count. We have some boosted ideas for the Operation Rank system that may allow us to be more specific with where we're applying pressure. If/when we decide to change or implement other limits, nosotros'll let yous know. These changes volition be coming out in our next release, which is currently in Open Beta.

To be clear, the above changes do not affect VRChat on PC.

Additionally, nosotros volition be taking some preventative measures to assist "close the tap" of Very Poor avatars. Nearly of these avatars come from avatar worlds, so we volition:

1. Find the nigh popular avatar worlds with Quest avatar pedestals that are more often than not (or all) ranked as Very Poor.
2. Contact the authors of these worlds and request that they either optimize the models they accept uploaded, or to remove them.
3. If no action is taken, the worlds will be removed from search.

We accept further deportment planned, but for the moment, we would like to enact these changes and see how the community adapts. Our promise is that the loosened limits along with the pressure level to improve avatar operation volition help reduce the "gray robot" problem, besides as improve performance overall.

We volition begin this process around the same time our adjacent release goes out.

Alright, but what about PC-only avatars? They're robots too.

Avatars that only accept PC avails announced equally a grey robot on Quest. We plan on addressing this with the Avatar Fallback system.

With Avatar Fallbacks, you will have the power to cull an avatar to serve every bit your Fallback. If someone from some other platform is looking at your avatar, simply your avatar lacks an asset package for the platform they're on, you will instead look like your Fallback.

Yous volition be able to choose from a list of our default avatars as your Fallback. In addition, you can upload an avatar yourself to act equally your Fallback avatar, but it must have a Operation Rank of Good or better and it must be marked as a fallback during upload. (That does mean you'll need to reupload to use it). This fallback volition exist the same no thing what avatar you're currently wearing.

Equally an example, if you are wearing a PC-merely avatar while speaking to your friend who is on the Oculus Quest, they will currently see y'all as a "greyness robot". With the Fallback arrangement, you volition instead exist able to choose how you appear to your friend while wearing any PC avatar that doesn't have a Quest version! Y'all can fifty-fifty cull one of your own avatars as your Fallback, as long as it meets the requirements given in a higher place and has been tagged appropriately during upload.

Avatar Fallback is a brand-new feature! You can read more about in our documentation. It'll be coming out in our adjacent release, which is currently in Open Beta.

We're making these changes to assistance solve (or at least mitigate) some of the more difficult problems for our Oculus Quest community — "everyone's a grey robot", and "wow, where'd my frames become later i clicked 'show avatar' on that wolfboy?"

Nosotros deliberated quite a long fourth dimension on how to address these issues! We decided on an approach that would both allow easier cosmos of avatars on the Quest platform, while also applying pressure level to create performant avatars. We want to avert hard limits on performance ranks on VRChat for Quest, just it may be an eventuality.

Going frontwards, we will proceed to implement both technical and policy changes for VRChat on the Oculus Quest / Quest two to avoid the same "grayness robot" and performance issues. In addition, we're continuing our ongoing performance work for VRChat on Quest and PC.

We believe these changes volition benefit the VRChat community as a whole, and will make it easier to make a performant Quest avatar!
