![]() ![]() ![]() We must create a simple mesh and texture for the final anticipation effect. Also, add the Noise module for some variation on the ember release. This makes the shape of the particles look stretched and will resemble embers. This time we also modified the renderer to be Stretched Billboard. A smaller sphere emitter shape and a positive value on Radial Velocity over Lifetime. Key Particle System settings for anticipation partįor the release part, just inverse the first effect. ![]() The default particle texture of Unity can be used, or just use any simple circle dot texture. For this, let's use a sphere as the particle's emitter shape and a negative value on Radial Velocity over Lifetime so it looks like energy is being collected. Let's start by making the charge part of the effect. Basically two stages within the anticipation VFX. I will create the anticipation part of the VFX using Unity's Particle System and GIMP (any other image manipulation program of your choice will also work).įor the anticipation portion of the VFX, I plan on doing an initial charge state and then a charge release state. Difference between clipping scroll enabled and disabled Anticipation VFX Here is a gif to showcase the difference between before and after using the Custom Vertex Stream. We will now be able to see the clamping scroll effect. Also, enable Custom Data option and modify the X value using a curve that goes from -1 to 1 or vice versa, depending on the direction of the scroll needed. Now for the clipping scroll, enable Custom Vertex Steams, then use the + icon > custom > custom 1.xyzw. You can refer to the image below for my basic particle settings. And using the Particle System, we can define the direction and duration of the clipping scroll. During this, the shader will scroll the texture automatically. The main idea is to spawn a single mesh at a fixed location for a certain time. This will make sense when we use it in the Particle System later. We cannot see the effects yet while only using the shader. So, the B channel is used to modify the Y vector of the gradient UV to change the value from -1to 1 or vice versa, depending on the direction of the scroll required. ![]() This is because the R and the G already have a purpose, and the B channel is there for us to use. Then, split and use the B channel of the gradient's UV to modify the UV. To get the desired effect, the gradient texture's UV will be modified using the Custom Vertex Streams module from the Unity Particle System.įirst, we need to change the Wrap Mode of the gradient texture to Clamp. We need to use a simple gradient texture to get the effect of the texture scrolling only once through the mesh. We must use the vertex colour to blend the texture alpha at the endpoints. We used a simple clamp node to do this in Blender, but things can be a little tricky in Unity. The tricky part is getting the alpha to work as intended. The UV offset along the y-axis is used on the main texture to constantly scroll along the mesh. This shader is pretty straightforward for the most part. The Unity Particle System can be used for other parts of the effect. We need to create a shader for UV scrolling in Unity similar to the one created in Blender. Once the mesh is finalized, export it to Unity. We can shift select the similar mesh and copy UV Maps and Modifiers to speed up the process. ![]()
