Blender Volume Shader

Blender has nice newish shader node for doing Volumetric renders i.e. foggy, misty environments, called Principled Volume. The way I have been doing it recently is to add a mesh cube around the object in the scene, see the image below. Tip: it helps to set the Cube Mesh Viewport Display to Display as Bounds. The Shader connections are shown below, note the Surface input is empty, the only connection is to the Volume. The settings I used in this demo are as shown and are a good start. The main tweaks are Density and Anisotropy, play with both to see the effect on the scene. ...

Blender Bevel

Blender Bevel Miter Outer

Blender Bevels come with a few options that are worth checking out before applying them. The interesting one for most use cases is the Miter Outer to change the spread pattern of the bevel on the outer edge. The default one is Sharp and is shown below: The second one is an Arc: And finally the Patch: Personally I like the Arc as it gives nicely spread out geometry around the sides and results in less shading issues. ...

August a Hairy Month

Almost the end of the month of August and I haven’t posted anything at all. So I managed to get one post in before I missed the deadline, a hair month indeed. I have, as you may have guessed, been looking at the hair system. I started with the old Particle system and them moved on to the new Geometry Nodes version that comes with Blender 4.2 and in my case the 4.2.1 LTS version. After watching a short video or two, I managed to get some quite decent results. I will link to the videos at the end. ...

Fix Windows Desktop Icon Spacing

I recently screwed up my Desktop Icons in Windows 11. I had been playing with the scaling factor and that had messed up the icon space scaling. The icons ended up with a massive hit size as shown above. To reset the icon sizes all you need to do is edit the WindowMetrics in the Windows Registry. Using the Registry Editor search for IconSpacing or follow the path in the image bellow. The default seems to be -1125 and if you see a massive negative number then that is the problem. ...

Editing Linux Grub Boot Loader

This is for my reference I recently needed to revert the Kernel on my iMac/Linux machine. I had updated to the latest version, which caused a problem with the Brightness not working anymore. On an iMac that meant I had no way to adjust the screen, as it doesn’t have any physical buttons. I attempted to edit the grub file from the boot loader, but that didn’t work as there doesn’t seem to be an editor in the boot shell. So after booting up a very bright UI I edited from the main UI. ...

Pencil Sharpener

Virtual writing implements

I had some fun recently with some pens and pencils, not real but rather virtual. Although the models are for the most part simple enough it was still a nice learning experience. I tried a few methods to model the pencils tip and in the end went with a Boolean cutter, which kind of fits with the real world. Basically a 3D pencil sharpener. Next, I decided to model a Stabilo pen, as I happened to have one laying around on my desk. The pen was nice in its youth, but now old and drying out. It is too faint to be of much use other than light outlining and model reference. ...

Boolean Node Group Use Example

Boolean Toggle Node Group

I recently posted a quick video of a very basic and yet useful Node Group setup in Blender. I think it was a little esoteric and perhaps people didn’t think it a serious post. It was serious and for me very useful. So I decided to explain the Group here and perhaps others may find it useful too. The Node Group As you see there are no nodes inside the Node Group this is intentional as none are actually needed. The magic is done by the input connector, labelled Toggle above. See the settings for this below. ...

April a Month Of Moves

I have been remiss in posting for a while and in April I posted nothing. The reason for this is the move I mentioned in the previous post. Well that and nothing really much of interest to say, apart from how much I hate cardboard now. May has had a slow start, still figuring out where to put stuff in the new place and how many curtains I need to hang, it is very bright here and I have four large windows, three full length with a door to open and a balcony, I know terrible. The problem is blocking the light from my screen in the daytime as it is very bright from behind. I have a solution for three of the windows and another pair of “blackouts” coming on the weekend, then I should be secure in my little dark man cave. ...
