Error. Haven't tested it myself though.
i've seen this model and it's probably the closest i've gotten to what i need; that said, it's not really what i'm looking for
the texture for that dash model is actually pretty close in appearance to the gif in the op post, but the shape is too dissimilar to what it should be
the left object on the pic above is the shape of the chaosrealm.info dash effect: a truncated cone type thingy that quickly expands in size
the dash effect in the OP probably looks like more of a triangular pyramid that expands in size; the "dash texture" would then be applied to the red/green/blue sides of the triangle (or maybe just red and green? idk), while the 4th uncolored side would just be transparent. then you slap on some dust particle effects afterwards
at this rate i'm probably just gonna learn how to model this myself lul. thanks for the reply though
edit: on second thought the animation would probably a bit more nuanced than just having a uniformly expanding triangle but wutev
