I am making an original gun with the official terratech modding tool. Is there a way to add a muzzle flash sprite animation to my gun? I created an original sprite image, added it to the "Muzzle Flash Anime" prefab, and set the material to Splites-Default. They were drawn fine on the unity preview screen, but when I checked the in-game behavior with local export, I saw pink sprites on the muzzle that appeared when the proper materials were not set.
