15 stylized portals for URP, drawn by procedural shaders instead of flipbooks: crisp at any scale, recoloured in seconds, open and close animation included.Fifteen portal effects, each with its own character: Arcane, Holy, Nature, Water, Ice, Fire, Electric, Crystal, Time, Holo, Dark, Necro, Blood, Poison and a Black Hole.Every portal is drawn by procedural shaders rather than rendered flipbooks. Nothing is baked into a texture atlas, so a portal stays sharp whether it fills the screen as a boss arena gateway or sits as a 64-pixel icon on a map. Scale it with the root transform and it holds up.That also makes them yours to change. Colours, spin and flow speeds, ring radii, arm counts, tick counts and glow widths are all material properties — retinting a portal to match your palette is a one minute job, not a trip back to Photoshop. The holographic frame takes any polygon from a triangle to a sixteen-sided ring; the vortices take any number of arms.Every portal opens and closes. A PortalFXController on the root scales the effect up while a noise dissolve fills it in, and back down to close, with Open() and Close() buttons in the Inspector and a Progress slider you can scrub in edit mode without entering play. One call drives all layers of a portal together.Suited to RPGs, roguelikes, tower defence, card and idle games — anywhere a summon, a teleport, a rift or a level gate needs to read instantly. Also useful as spawn markers, boss entrances and shop portals.Requires the Universal Render Pipeline. Bloom in your Volume profile is strongly recommended: these effects are authored as emissive light and look flat without it. A demo scene with all fifteen is included, along with documentation.• 15 portal prefabs, one per effect: Arcane, Holy, Nature, Water, Ice, Fire, Electric, Crystal, Time, Holo, Dark, Necro, Blood, Poison, Black Hole• 58 custom shaders, all URP unlit, single pass, written for this pack• 80 materials• 15 textures: 5× 1024×1024, 1× 1024×512, 1× 793×336, 1× 512×512, 1× 400×488, 4× 256×256, 1× 226×188, 1× 128×128• 56 shader layers and 29 particle systems in total — 2 to 7 layers and 0 to 4 particle systems per portal• PortalFXController script with Open() / Close() / Apply(progress), plus a custom inspector with Open and Close buttons and an edit-mode Progress slider• Demo scene with all 15 portals and a post-processing profile• No lights, no shadow casters, no extra render passes• Unity 6000.0 or newer, Universal Render Pipeline• The Water portal samples the scene behind it — Opaque Texture must be enabled in your URP asset. Every other portal is self-contained.AI assistance was used during development, under human direction and review.Shaders: the procedural shaders in this package were written with an AI coding assistant. Each one was specified, reviewed, tested in-editor and iterated on by me. The visual direction, the parameter tuning and the final look of every portal are my own work and decisions. No shader was shipped without being inspected and adjusted by hand.Textures and sprites: some of the images in this package started as AI-generated material and were then edited and finished by hand by me before being used.Documentation and the editor tooling used to build the demo scene were drafted with AI assistance and reviewed by me.Some AI-generated images were used purely as visual reference during development. They are not part of the package and are not redistributed.All content shipped in this package — prefabs, shaders, materials, textures and the demo scene — was assembled, tested and approved by me.
