Blender Day 10: one time edit object in blender

Alright, since we've already learned how to add, remove, and delete things in this Blender environment, let's now focus on making some changes. First, let's select and delete this object. We can then add a new one by using the shortcut Shift + A. Let's add a UV sphere to the scene. Great, now let's move it a little closer. Use the mouse wheel to zoom in for a better view of the UV sphere. As you can see, the UV sphere has many faces. When you add an object to the scene, an operation panel specific to that object appears. This panel allows you to quickly adjust the object's properties. However, if you do anything other than clicking "Add UV Sphere" in this panel, it will disappear, and you'll have to modify the UV sphere in a different way. So, let's create the UV sphere and move it a bit using the screen's cursor. Let's align it to the right to give us more space. We can also hide the background to improve our view. Now, let's change the UV sphere. As you know, the UV sphere is a spherical object with many faces. We can adjust the segments and rings of the UV sphere. Let me demonstrate. By clicking the left mouse button and dragging, we can change the number of segments. This affects the number of faces on the UV sphere. We can also adjust the number of rings. This allows us to create a low-poly object with fewer faces. In later videos, we'll discuss polygons in more detail. The key is to keep the number of faces as low as possible for efficiency. If a game has too many polygons, it can crash. So, it's important to optimize them. We'll use different techniques to create smooth objects later on. We can also change the radius of the UV sphere, making it smaller or larger. Here's a little trick: if you want to fine-tune the adjustments, hold down the Shift key. This will slow down the operation, allowing for more precise changes. I think that covers the main points of this one-time operation panel. Once you're done with it, you can click anywhere else to make it disappear. You can also press "N" to hide the panel on the right for a better view. Press "N" again to bring it back. Let's move the UV sphere back to its original position and align it to the left. Okay, that pretty much sums up this lecture. We've learned how to add and delete objects, how to make one-time changes using the operation panel, and how to modify the UV sphere. I'll see you in the next lecture. Bye for now!
