![]() ![]() First we can choose our force type, this will let us to create the kind of force we need, for example the local force is better for animating individual objects, and the word force is better is we want to share our forces in another brushes. We have some really interesting settings. You can find this section in Tubes > Behavior > Turbulence. Here we are going to start exploring the Turbulence panel, here is the image. The Behavior panel is inside the creation panel. Well, first I will explain the settings from the Behavior section and then I will show you how to configure this settings for our grass wind simulation. I will show you some examples of that in the tree growing simulation. These are the settings made to control a lot of the aspects for the animation behavior, but you have to know that you can set keys in every single panel, from shading to number of branches, you can animate almost everything, so be creative, there's no limitation. The second is the Gaps section and the third one is the Flow Animation section. ![]() In this image you can see the tree mayor animation sections for paint effects, the first one is the Behavior sections, which will have the subsections of displacement, forces, turbulence, spiral, and bend. Here I will explain the animation attributes from the paint effects stroke settings, but we can use control curves and make it react to field forces from the dynamics system in Maya 7, or you can turn it into polygons and then make it soft bodies and make it react to forces as well, but here I will show the stroke settings for the animation in the paint effects system Now I want to simulate some wind effecting the grass and for that I can use some different techniques. Here is the first pass of paint effects, the grass.Īnd now after configuring my settings, here is the actual render of my grass. Here you can see the terrain geometry with some simple shader. Here you can see part of the process (again I will show this really quick). I start painting the grass in the terrain, and then I change the settings until I get the shape and colors that I want. I will explain better the clouds stroke, and some thing about the trees, but the important thing here, is the animation. In this tutorial I created the grass, the trees and the clouds in the same way that I show you in the first part of the tutorial, so I will not go deep in that here. After that I set my camera and once I have this ready, I can start to work in how I want to apply the paint effects into my scene. I made a simple sketch of the image I wanted and then I created the terrain and applied some materials. Let me say some that come in to my mind right now, we can create animated clouds, we can create vegetation, and trees that we can turn into polygons and then use another render system like Mental Ray for rendering and conserve the animation we created in the paint effects system, we can create water simulations, hair that can be animated in an incredibly realistic way, we can make that every step of our characters deform the grass when they walk, we can animate the paint effects and then make them emit particles (I can't imagine how many possibilities this can generate), you can make the tubes behave like springs, you can create so many things and in so many easy ways Well now starting with the scene, I will share my files with you, so you can explore the settings I use First Stage: Set up your scene Paint effects are something like a particle system, and that it's some of the things that let us created so many possibilities. Something I have to remark on is the fact that the only geometry that this scene has is the ground, everything else is done in the postproduction process that uses paint effects for rendering (see image), amazing right!, well it's more amazing the rendering time, it takes about 1:08 seconds to render for one frame!!!, and you can see a lot of geometry there. It is a simple animation of blowing wind moving some grass, the clouds and the trees in the background, some texture animation and a simple growing simulation for the tree in the front. Here is the animation of the project we are going to create. This will be a medium level tutorial, so is better if you have a previous knowledge of paint effects or you can read the first tutorial here. First, I want to make a little introduction to the possibilities that paint effects has in terms of animation. I'm really satisfied with the comments and suggestions and thanks to that, here is the second tutorial and I will teach you how to create animations with Paint Effects and how to simulate some real forces in your scenes and also some growing simulations. ![]() My name is Isidro Fernandez, and I want to say thanks to all of you for the comments I received from a lot of people who want to learn a little more. Hi, welcome to the second part of the series of Paint Effects Articles. ![]()
