Cavity Mode

If you want to see your model in solid mode with more depth and detail, you can turn on the cavity option in the shading menu and choose both as the mode. This will create an ambient occlusion effect, which simulates how light, and shadow interact in real life. This can help you work on complex models more easily and also make them look more realistic and cooler.
Startup File

You can save your current blender project as the startup file, so that you can begin your future projects with the same settings and scene. To do this, go to the file menu, select defaults, and click on save startup file. This will overwrite the default startup file with your current project. For example, if you have a tube object in your scene, you can save it as the startup file and have a tube ready every time you launch blender.
Model Tubes Pipes Blender Tips

To create tubes or pipes in blender, you can start with any primitive object and enter edit mode. Then, press the m key and choose at center to merge all the vertices into one. Next, you can extrude the vertex along any axis or curve to form the shape of your tube or pipe. You can also bevel the edges to make them smoother.
Finally, you can convert the object to a curve by going to the object data properties panel and clicking on convert to curve. This will allow you to adjust the bevel depth of your curve and make it look like a tube or pipe. Don’t forget to shade smooth your object for a better result.
Bevel Fix

Sometimes, when you try to bevel an object like this one, you may encounter some problems with the corners. They may look distorted or jagged, instead of smooth and round. To fix this issue, you can change the miter type in the bevel settings. The miter type determines how the bevels are applied to the corners of your object. Blender Tips to correct the bevel
By default, it is set to sharp, which can cause some artifacts. To make the corners look better, you can switch the miter type to arc. This will create a smooth arc at the corner, instead of a sharp angle. You can find this option in the bevel window, if you are using the bevel tool, or in the bevel modifier settings, if you are using the modifier.
Noodle Nodes
If you want to make your node connections look more curved and smooth, you can change the noodle curving setting in the preferences. The noodle curving setting controls how much the node connections bend in the node editor.
To access this setting, you need to open the preferences window, go to the themes tab, and select node editor from the list. Then, you can adjust the noodle curving value by dragging the slider or typing a number. I personally prefer to set it to 5, but you can choose any value that suits your taste.
Alt for Orthographic
You don’t need a numpad on your keyboard to switch to orthographic view in blender. There is a better way to do it without using the emulate numpad feature. All you have to do is hold the alt key and rotate your view with the mouse. This will snap your view to the nearest orthographic axis. I find this method much faster and easier than using the numpad, even though I have one on my keyboard.
Blender Tips – Orbit Shot
Creating an orbit shot for your animation can be tricky if you don’t know how to animate the camera. You might be tempted to just rotate the whole scene around the camera, To do this, you need to create an empty object in your scene and place it at the center of your orbit.
Then, you need to select your camera and press Ctrl+P to parent it to the empty object. This will make the camera follow the empty object wherever it goes. Next, you need to keyframe the rotation of the empty object around the Z axis.
Shit H
Blender tip to hide other objects. If you want to hide the object that you have selected, you can press the H key on your keyboard. However, if you want to do the opposite and hide everything except the object that you have selected, you can press Shift+H instead. This will make the selected object stand out and remove any distractions from the background. This can be very useful when you are working on larger models, and you want to focus on a specific part of them.
Render Visibility

If you want to control which objects are visible in the viewport and which ones are visible in the render, you can use the visibility icons in the top right corner of your screen. These icons are the eye icon and the camera icon. The eye icon lets you hide or show objects in the viewport, while the camera icon lets you hide or show objects in the render.
To enable these icons, you need to click on the filter icon next to them and check the boxes for viewport and render visibility. Then, you can click on the eye or camera icon for each object to toggle its visibility. This way, you can have more flexibility and creativity with your scene.
Blender Tips- Delete Material

Blender does not have a straightforward way to delete materials from your scene. However, there is a workaround that you can use. You can go to the outliner window and change the mode from view layer to blender file. This will show you all the data blocks in your file, including materials. You can then right-click on any material that you want to delete and choose delete from the menu. This will remove the material from your file and free up some memory.
Decals
Decals are another useful feature that you can use to enhance your models. Decals are images or textures that you can apply to the surface of your objects, without affecting their geometry. They can add details such as scratches, dirt, stickers, logos, and more. You can create decals in blender using the image as planes add-on or import them from external sources.
Blender Tips – Better Trees
One way to improve the performance of your nature scenes is to render the trees separately in another blender file with similar lighting conditions. Then, you can import the rendered images of the trees into your main scene, instead of using 3D models. This method can reduce the memory and render time of your scene, but it only works for still images, not animations. For animations, you need to use 3D models of the trees, otherwise they will look flat and unrealistic.
Blender Tips – Render Forever
If you want to preview your render without any sample limit, you can set the viewport samples to 0 in the render properties panel. This will make the viewport render as long as you want, until you stop it manually. This can help you get a better idea of how many samples you need for your final render, by comparing the quality and noise level of the viewport render with different sample values.
Viewer Node Compositing

If you want to see your compositor effects in real time, you don’t need to use the viewer node. There is a simpler way to do it. Just open a new window and change the editor type to image editor. Then, select the render result from the drop-down menu. This will show you the output of your compositor nodes, and update it automatically whenever you make any changes. This is a very convenient way to preview your effects and adjust them as you like.
Blender Tips – Fog Effects
If you want to add some atmospheric effects to your render, such as fog or haze, you may think that you need to use volumes. Volumes can create realistic and beautiful effects, but they also increase your render time significantly. Fortunately, there is another way to create fog effects that does not affect your render time at all.
This is the mist pass. The mist pass is a render pass that you can enable in the view layer properties panel. It creates a grayscale image that represents the distance of the objects from the camera. The closer objects are black, and the farther objects are white. You can use this image to mix with your final render and create a fog effect. To enable the mist pass, you need to go to the view layer properties panel and click on the shading drop-down menu.
Then, check the box for mist under passes. To preview the mist pass, you need to go to the world properties panel and find the mist pass section. There, you can adjust the start and depth values of the mist. The start value determines how far from the camera the mist begins, and the depth value determines how thick the mist is. You can see the effect of these values in the viewport, if you switch to look dev mode.
After rendering your scene, you can use the compositor to mix your image output with the mist pass. You need to add a color mix node and connect your image output to the first input and your mist pass to the second input. Then, set the blend mode to screen or add, depending on how bright you want your fog to be. You can also add a color ramp node between the mist pass and the color mix node, to tweak the intensity and contrast of the fog.
