Blender is a powerful open-source tool for 2D and 3D graphics, full-on animation, compositing, and post-production. It is used to create movies and special effects, even in HD. In Blender Essential Training, Roger Wickes offers new Blender users a thorough explanation of its interface, tools, and features. He also demonstrates practical techniques and shows how to access the online and openndash;content resources of this amazing tool. Specific 3D techniques covered include navigating in 3D space, using cameras and lights, and rendering. Roger demonstrates how to rig, animate, and composite a character over live action. Exercise files accompany the course.
Almost anything in Blender can be animated, including the colors of things. This tutorial is going to show you how to animate and change the colors of an object. So let's go ahead and jump over to Animation Screen layout and we're going to change from an Action Editor here to be my Buttons Window and align it vertically so that I can see it and work with it. So if we come over here to the Shading Context, let's go ahead and switch to Camera View by pressing 0 on your keypad.
So we can see the cube, and press Z so we go into Shaded view. So now we have the color of the cube. Let's make it of pretty color, blue. So now, the cube is blue. Down here in the IPO window, we can switch to a Material set of IPOs. With our cursor over here, and the Shading panel, we press I. Now, we're going to insert a key not for the object Location, Rotation, and Scale, but instead we're going to key the material.
So we can key a whole bunch of different stuff. We can actually key everything if we want to. For this training tutorial, I'm just going to key the RGB. So the Red, Green, and Blue. So I'm keying the R, G, and B values here. At Frame 81, the cube is blue. So if we scoot on back to frame 1, and make the cube-- Let's make it fuschia. And over here then press I and key the colors again we have, and I'm going to pan this view by holding Shift+Middle- mouse button, and then moving my mouse to the right.
We have now the IPO curve for the colors and now that we can see that the colors change and as we go through and cycle through our animation, we can see in 3D view that the color of the object is actually changing. These are the exact same curve controls as before. I can right-click on a curve, Tab and there is my Bezier Handles to change the shape of the curve. I can break the handle into a vector by pressing V. I can also extend and this is a little tricky when it gets out into math.
But I can also change the extrapolation type of the curve. So if I wanted just to go linearly between the two colors, I could choose Linear and now instead of it being a nice smooth curve, now it's a straight line. So now the curve changes linearly or I can have it jump from one color to the other by changing from the other kinds of Interpolation Modes to Constant. Then I can also manually set the value for any curve, either by jumping to the keyframe there and then changing the value over here in this slider, or I can edit the curve and changing the value over here in the Y value setting for that particular curve.
So I can tab into Edit Mode and right- click and then set this value manually. That's how you change the colors of objects over time and animate the colors of any object in Blender by animating the material settings.
