![]() To solve this, we close the Visual Effect Graph window and go back to Shader Graph. The particles also “die” very abruptly instead of slowly fading out. Each particle needs a unique offset in the cloud pattern. Notice how all the particles have the scrolling cloud shader, but they all have the exact same pattern. ![]() ![]() Notice how the particle effect in the Game tab instantly responds to this change and now shows something that starts to look a little like the smoke effect were going for. Under “Shader Graph”, select the shader we created with Shader Graph. Go to the bottommost node, Output Particle Quad. You will now see a particle system in your Game tab, using the deafult effect:ĭouble click the VFX asset to open the new particle effect in Visual Effects Graph. Drag and drop the new VFX asset to the scene in the Hierarchy tab, creating a new game object. In the Assets folder in the Project tab, right click > Create > Visual Effects > Visual Effect Graph. We need a Tiling and Offset node to control the scrolling of the cloud pattern, and a Time node to make it change the offset over time, in other words scroll. I will not cover how to do that, but I will share the image I used: I created mine in Krita, a free image editor. Now, start with creating a Sample Texture 2D node and use a simple cloud image for it. Double click the shader to open Shader Graph. In the Assets folder in the Project tab, right click > Create > Shader > VFX Shader Graph. In the Hierarchy tab, select the Main Camera and change the Background Type from Skybox to a solid black color. ![]() Select Visual Effects in the list and enable “Experimental Operators / Blocks”. At the top, under “Scriptable Render Pipeline Settings”, select the UniversalRenderPipelineAsset asset we just created. In the Assets folder in the Project tab, right click > Create > Rendering > Universal Render Pipeline > Pipeline Asset Do the same for “Visual Effect Graph” and “Universal RP”. In Unity, click Window > Package Manager and search for “Shader Graph” and install it. Start a new empty project from Unity Hub. Do not skip any of these steps or you will have some very cryptic error messages and spend a lot of time googling them. If you get stuck anywhere, you can load the shaders I created:įirst we will setup Unity. ![]() We will create it using Unity’s own free graphic tools for Shaders and VFX, Shader Graph and Visual Effect Graph. ![]()
