unity shader flowmap

Beta Joined: Dec 10, Posts: I'm trying to recreate a flow map shader that I had previously made in Shader Forge. Though the two graphs are logically identical, the results are different. In shader graph, the UVs are being offset in both the X and Y directions. Does anyone know what might be causing this discrepancy? Shader Forge correct results - tested in Unity Joined: Jun 30, Posts: Switch from linear to gamma color space or simply disable sRGB Color Texture in the texture import settings.

And your remap should be from 0, 1 to By changing normal maps tiling, main color, reflection color, specular color, flow speeds and cycle lengths a variety of effects is possible:. Remember, that for flow map creation you can use FlowEd. Any ideas. Note that the reflection might be severely distorted due to surface bumpiness, for testing purposes set bump map to the neutral color. But it is working now there is a reflection on the water plane only now i need to adjust the script so it renders it better resolution.

Could be tricky because animated water already uses so many textures, but if you can spare another texture unit just add foam texture you can resign on one of the normal maps and use the same one twice insteadanimate it exactly the same way I animate normal maps and lerp between water and foam color depending on the speed. I just want to use the foam texture on the spots where there are rapids so it is kinda white water.

I first want to say that I am an internet hermit and typically never comment or reply to anything. I stumbled upon this shader while trying to find a solution to the water in my game. Your shader was exactly what I was looking for. So, thank you for creating this. Thank you for sharing. Great shader, exactly what we needed to add a decorative pond to our scene. One question. We need to simulate a paused scene.

Hi this looks really cool. Could you point me to a resource to learn how to use it? I created a plane? I assume I need the mesh plane to attach all these things to.? Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. I will credit you when the game is finished. Cool : Good luck with your game.

If it has a website, let me know. Hi there, Is there a way to add reflections to the shader like the normal pro daylight water? Hi, sorry to bother you again but i want to add foam to the places where it flows very rapidly how to do that?

Okay thanks found it i will make a video as soon as i imported it in the scene.Discussion in ' Assets and Asset Store ' started by jboothFeb 8, Search Unity. Log in Create a Unity ID. Unity Forum. Forums Quick Links.

Texture Distortion

Joined: Jan 6, Posts: 4, A while back I wrote a nice little vertex painting system that used Unity 5. I've added a ton of new features to the system, a fully PBR splat map shader with flow mapping and support for 5 splat channels, and released it on my GitHub account today.

Flowmap Generator is a tool for creating flowmaps for use in shaders using a fluid simulation. A flowmap is a texture that contains velocity vectors that can be used to create the illusion of flowing water, blowing sand, etc.

Flowmaps can be difficult to create, especially on a large scale. Several tools exist for hand painting the velocity vectors, but this can be time consuming and if the geometry changes it is necessary to repaint the flowmap. Flowmap Generator lets you set up a simulation that can be easily edited and resimulated when needed. Flowmap Generator comes in two forms, as a Unity plugin and a stand alone program. The Unity plugin allows for tight integration with Unity with features like dynamically updating flowmaps, automatically assigning flowmap textures and UVs to materials and more.

The stand alone program allows for baking flowmap textures to be used in any game engine. Flowmap Generator Features Purchase Downloads Documentation Support Flowmap Generator is a tool for creating flowmaps for use in shaders using a fluid simulation. Features Simulation Fields The simulation is controlled by placing fields which interact with the fluid simulation.

Several different fields are available including vortexes, directional forces and calming fields. Placing fields within prefabs is supported and allows quick and easy scene creation. Render Heightmaps Render heightmaps from scene geometry. Surface Flow Supports surface flow simulations for fluid flowing on a surface rivers, lava, blowing sand, etc.

Speed Flowmap Generator supports GPU acceleration which allows realtime simulation of large flowmaps. For the free version of Unity multithreading is supported. Unity Integration With the Unity plugin, the flowmap that is currently being simulated can be assigned to a material to allow for a realtime preview of the flowmap. With Unity Pro it is possible for Flowmap Generator to render out a heightmap of the scene to let the flowmap simulation be affected by objects in the scene.

I also have a small repository on GitHub where I study shaders in Unity.

This shader can be found there with example of usage. More information about the shader can be fount here. There is a nice tool out there for creating flow maps. So this is the shader code. I am not good at writing shaders and it can be not very efficient, but it does its job:.

This tutorial assumes you've gone through the Basics series, plus the Rendering series up to at least part 6, Bumpiness.

Lava Flowing Shader

This tutorial is made with Unity When a liquid doesn't move, it is visually indistinguishable from a solid. Are you looking at water, jelly, or glass?

Is that still pool frozen or not? To be sure, disturb it and observe whether it deforms, and if so how. Merely creating a material that looks like moving water isn't enough, it actually has to move. Otherwise it's like a glass sculpture of water, or water frozen in time. That's good enough for a picture, but not for a movie or a game. Most of the time, we just want a surface to be made out of water, or mud, or lava, or some magical effect that visually behaves like a liquid.

It doesn't need to be interactive, just appear believable when casually observed. So we don't need to come up with a complex water physics simulation. All we need is some movement added to a regular material. This can be done by animating the UV coordinates used for texturing. For this tutorial, you can start with a new project, set to use linear color space rendering. If you're using Unityselect the default 3D pipeline, not lightweight or HD. Then create a new standard surface shader.

As we're going to simulate a flowing surface by distorting texture mapping, name it DistortionFlow. Below is the new shader, with all comments and unneeded parts removed. To make it easy to see how the UV coordinates are deformed, you can use this test texture. Create a material that uses our shader, with the test texture as its albedo map. Set its tiling to 4 so we can see how the texture repeats.

Then add a quad to the scene with this material. That makes it easy to look at it from any angle. The code for flowing UV coordinates is generic, so we'll put it in a separate Flow. It should return the new flowed UV coordinates. We begin with the most straightforward displacement, which is simply adding the time to both coordinates.

Then use the new UV coordinates to sample our texture. As we're increasing both coordinates by the same amount, the texture slides diagonally. Because we adding the time, it slides from top right to bottom left. And because we're using the default wrap mode for our texture, the animation loops every second. The animation is only visible when the time value increases.

This is the case when the editor is in play mode, but you can also enable time progression in edit mode, by enabling Animated Materials via the Scene window toolbar. Actually, the time value used by materials increases each time the editor redraws the scene. So when Animated Materials is disabled you will see the texture slide a bit each time you edit something.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Flow maps are a texture based way to make detailed texture animations e. Basically it uses 2 channels of a texture to move texture coordinates along the x and y axes. Each channel controls one axis. A channel color value of 0. So with the right values textures can be moved in all directions and that for each location individually unlike simple uv scroll. River example:. Also to minimize the pulsing effect a noise texture can be used to add some random offset. There are two example scenes in the demo folder that demostrate how to use flow maps for basic water and lava materials.
