Models disappearing / reappearing in SFM

[NibSmoker]

I'm using pony eyebrow models, and when I get close to the for positioning, they disappear, then reappear when I move far away. This is a glitch I've noticed. Does anyone know the fix to this?

Have you resized the models (or the models they're locked to)?

Models disappearing like this is usually caused by a model's hitboxes not lining up with the model - because SFM uses the hitboxes as a simplified way of calculating whether the model is in shot (and should therefore be rendered), if the hitboxes don't properly cover the model, the model will disappear from some camera angles.

The problem is that scaling a model's root_transform control does not correctly scale the hit boxes to match the model. If you're scaling a model, you need to use a proper bone, NOT the root_transform control.

Usually for characters, the right bone to add the scale control to is their pelvis, to which everything else is (usually) a descendent bone of.

I had not changed the scale for these models. I'm confused since I'm sort of new to SFM.

If you've not resized anything (which is the most common cause of this error), then you'll need to tell us specifically which model is the problem so we can inspect it ourselves - please give us a direct link to where you got it from.

(And I do mean a link please - just describing where to find it is much more of a nuisance and may potentially involve us finding and checking the wrong model).

You'll have to wait for any response from me, as I'll be going to bed shortly, but another member may be able to help in the meantime.

The models are from @aeridiccore on Tumblr. They are anthropomorphic pony models. Sadly I can't give a link as they are private models, which the link is give to those who purchase the models. All I can say is that when I spawn the model of the eyebrows, they glitch out as I described without any editing size of the model within SFM.

[Marco Skoll]

If they're paid for models (and it's genuinely not that you've resized anything, even the models the eyebrows are attached to) then I'm not even going to suggest any of the possible fixes, because you should be making this as a complaint to the creator.

Once a transaction is involved, they are compelled to provide you with a product that lives up to all reasonable expectations.

I did complain to and he told me he could not spot the issue, since nobody else has had this issue before. If you could tell me the fix I'd really apprecitae it. And he's a busy SFM artist making comissions for people and such. He doesn't have time to really help people.

What if they are not paid models? I ported some truck models from gmod and they have the same bug ( https://steamcommunity.com/sharedfiles/filedetails/?id=193728296 )
Any help guys? Thanks!

bcz u need to put proper https://developer.valvesoftware.com/wiki/$bbox into qc.
even Zappy said compiler automatically write it when model compiled, but seems autodetection of model's rendering hull is not always working well

PS nice necro btw

Hey guys, I think I have a similar problem. When I dont move my model it shows a t pose and in one specific location, when I move it then it shows the correct positions and all the movement but when I dont move my character again then it again shows t pose
