History SpecialEffectFailure / WesternAnimation

* ''WesternAnimation/{{Rollbots}}'' has had a few.

** At several points in ''Prophecies and Guesstimates'', once Spin's EleventhHourSuperpower activates, Spin is not glowing when he's supposed to be.

** In ''Vett'', when Spin and Vett are fighting at Xendover Stadium, at one point Vett is knocked onto his back by a hit but flips up instantly, in a very broken-looking moment.
** The Ajax Trax from ''Ajax'' make no sense whatsoever, with a vague, choppy sort of teleportation.
** In ''Inferno'', Macro's flamethrower flames seem very solid...
** The crazed Zurasho who attacks Spin and Octo in ''#044'' has the same problem in her blowtorch that Macro has with his flamethrower.
** Botch's laser from ''Scorched'' seems very choppy.

* The animation in the 2018 ''WesternAnimation/WatershipDown'' film was widely criticized, with most saying it resembles a UsefulNotes/Playstation2 cutscene.

* In the finale of ''WesternAnimation/AvatarTheLastAirbender'', the airships are CG rendered at a noticeably low and choppy framerate that gives the impression of a UsefulNotes/SuperNintendoEntertainmentSystem Super FX game.

** One scene has a group of elderlies watching home made pornography and one of the elderly men [[GroinAttack punches himself in the crotch repeatedly]] to "wake up" his penis so he can get aroused by the video. A woman sitting next to him can be seen glancing over as he hits himself, but because the animation is looped, you can see the woman's eyes quickly changing between looking at the video and looking at the man.

* In the Finale of ''WesternAnimation/AvatarTheLastAirbender'', the airships are CG rendered at a noticeably low and choppy framerate that gives the impression of a UsefulNotes/SuperNintendoEntertainmentSystem Super FX game.
** SequelSeries ''WesternAnimation/TheLegendOfKorra'' doesn't escape either. In "Turning The Tides", the HumongousMecha are incredibly slow-moving and poorly-rendered CGI. The mecha look fine in previous episodes, and their deficiencies only become obvious when they're attacking in broad daylight as opposed to a darkened corridor. This is especially bad, given the exact same episode has traditionally-animated airships that look quite good.

* Before the franchise got actual cartoons for TV, ''Toys/{{Gormiti}}'' had a few animated promotional shorts released on DVD. Most of them are done in very ugly CG, but the original one takes the cake. The short is 9 minutes long and only one third of it features original (but very choppy looking) 2D animations, while the remainder is made of CG estabilishing shots, black silhouettes and character artwork taken from the cards that came with the figures with superimposed animated mouths and, most bafflingly, red lights over every character's eyes to make the static images look more alive. The real failure is when one of the Forest Gormiti, Mimeticus, is shown "running" through the woods and the aforemented red lights move slightly faster than the character, getting misaligned to his eyes in the last few frames of the scene.

* The Creator/HannaBarbera special ''Jack And The Beanstalk,'' which actually won an Emmy, had a scene where Jack (Gene Kelly) climbs up onto the back of the giant's goose. The platform on which Kelly climbs permeates noticeably through the background.

* In the ''WesternAnimation/FamilyGuy'' episode "He's Too Sexy for his Fat", Chris in one scene is grabbed in a bear's mouth and is shaken repeatedly. The bear and Chris are seen in the reflection in the river, and there's a difference in the animation speed between the characters and the reflection; the reflection's animation is at normal speed, while the animation of the bear and Chris suddenly doubles and is out of sync with the animations in the reflection because of it.
** Another episode has Peter being chased around by a dog before he climbs up a wall and into a window. The dog keeps up with Peter, but then suddenly runs slower than normal, making it look like Peter is able to outrun the dog by miles.

* The infamous crash scene from the ''WesternAnimation/ThomasAndFriends'' episode "The Flying Kipper". Pay very close attention during the scene when they show Henry crashing into the freight train head-first.

* ''WesternAnimation/TheSimpsons'' parodies it in the episode 'Last Tap Dance in Springfield', when Lisa is watching short films of Vickie Valentine from the 1940s. Vick and her butler begin dancing, which supposedly "cures" her cat's illness. The cat reacts by rubbing her eyes, which are clearly off-camera hand props waving around in front of the cat's eyes. This is likely a reference to the bare-bones special effects of early-1900s film.

* In an episode of ''WesternAnimation/MuppetBabies'' spoofing ''Franchise/StarTrek'', Captain Kermit gives orders to activate the [[FasterThanLightTravel Warp Drive]]. The dialogue implies that the warp drive is warping everything else, but for some reason somebody forgot to warp the video.

** If you want to compare.

** Transformation sequences, especially for the original characters, turn out particularly bad-looking in a few shots. Dinobot and Rhinox's may be the worst; the characters [[ShowAccuracyToyAccuracy only faintly resemble their toys]], so their transformations cheat a lot. At times, Dinobot's robot torso simply sprouts out of his beast mode, while his robot and beast limbs all clip through each other, and his raptor head floats down to form his chest-plate. Rhinox's rhino mode's back legs morph into giant shapeless blobs before being replaced by his robot legs, and both characters have a tendency to deform into all sorts of weird shapes.

* In a WesternAnimation/JoeOrioloFelixTheCat episode [[Recap/JoeOrioloFelixTheCat1x05FelixTheCatSuit "Felix The Cat Suit"]], The Professor is running past whats supposed to be a WraparoundBackground, but the background is clearly way too short--so short, in fact, that you can ''clearly'' see the cutoff point where the background is supposed to loop over and over again!

* While the CG in WesternAnimation/FleabagMonkeyface is already subpar, a special mention has to go to the [[HalfidenticalTwins Smugley twins]], where you can easily tell that they used the same model for the girl due to the fact that there's a ''noticeable line where the long hair was attached to the other model''.
