Blender beginner tips
Since expanding your horizons has never been a bad idea, the admin decided to try learning how to make models in Blender. On this page, we will post small reminders about hotkeys or just tricks that will help beginners. Of course, this is all familiar to pros, but for beginners it will be useful information.
If we have several vertices that are looped and you need to select them all, that is, select several vertices, to save time and convenience, you can hold down the Alt key and click on the edge between the vertices that you want to select.
One of the quick ways to make a rounding (for example, on the edge of a wheel) is to select the outer edge with a ring, press Ctrl + B and try dragging in any direction. If you can't see the effect for a long time, try selecting one of the axes after pressing the keys, also by pressing the corresponding key (X, Y or Z) and then dragging the cursor.
In some cases, Bevel may not work correctly and additional edges will appear on the wrong axis. If you have changed the scale of the model, it will be advisable to apply it. go to Object select all - A, press Ctrl + A and select Scale. Also go to Edit mode, select all - A, press M and select By Distance. After that, everything should work.
If you need to make a "sharp indentation" of a certain line into the middle of an object (for example, a tread mark on a car tire), you need to select certain edges of our line for indentation (in edit mode 2) and press E and S, after which you use the cursor to adjust the depth of the indentation.
If we need to make circular holes in an object at regular intervals (such as the holes for connecting a car wheel), we can do the following:
First, you need to create a round element for the hole (preferably a cylinder, I'll explain why later). We make it the right size, and place it in the place where one of the holes is needed.
Next, with the selected cylinder, activate the spin function, via the control panel on the left or via the Shift + Space keys. At the same time, a settings field will appear at the bottom left, where in item Steps we set the number of holes we need to one less, that is, if we need 6, we set 5, click on the plus icon and, by moving the mouse cursor, we see how our holes are distributed in a circle.
Next, we move on to our main shape, where we need to make holes, and add modifier General - Boolean. Chosen Difference, and in Object select our cylinder, and click button Apply (The apply button will appear when you click on the triangle, next to the cross button in the modifier).
After that, you can delete the cylinder object, but as you can see, the holes themselves have not appeared, there are only points from them. If we have a flat object where we need to make a hole, then you can simply switch to edit mode 3, click on the hole, press X and select Face. This will create a flat, beautiful hole. However, if the object with the hole has a thickness, when you delete it, you will have a void, so instead of deleting Face, you need to select all the points of the entrance and exit hole, press Ctrl + E and select Bridge Edge Loops. This will automatically create segments between opposite vertices and remove the extra wall, so you will get a perfect hole.
Over time, anyone will start to encounter such incomprehensible behavior in blender as strange camera operation - zoom slows down and camera movement slows down. For a quick fix, you need to go to settings - Edit - Preferences - Navigation and check the box at item Depth.
Improving visuals in Blender is a separate and very large topic that can be studied for years, but now we will add a note about a small attempt to improve the appearance in the render.
In the render settings section, first of all, make sure that EEVEE is set, then go down to the Raytracing settings section, turn it on, if it is on, turn on Fast GI Approximation, and in Method, select Ambient Occlusion.
Of course, these are all subjective things and it is possible that these settings may not be suitable for a specific case, so you need to experiment and look for new and new methods of improvement.
If you need to place an arbitrary single point on an edge, you can do it as follows: select the edge in edit mode, right-click on it and select item Subdivide - deselect, switch to vertex edit mode and see our new point on the edge.
