Sequence playing incorrectly, choppy

[tacit slate]

My model has a sequence called "spin" and when viewed in hlmv, or the gmod model viewer addon it looks fine, but when animated with lua or rubat's easy animation tool it's really "choppy" and not sure what the issue is

this is what it looks like in hlmv/gmmv:

and this is what it looks like when animated with lua

this is the qc

$sequence "spin" {
    "anims\spin.smd"
    fps 60
    loop
}

hey, the giftbox rotation looks fine for me. you wanna send the mdl file over so I can look at it?

my bad, just saw this

[shut shoal]

it's just models\drive.mdl?

[tacit slate]

no, it's models\chao\animals\drive.mdl but directory shouldn't matter, should it?

[shut shoal]

yeah it matters

anyways it's fine on my end (using rubat's easy animation tool)

[tacit slate]
