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....

Busy with Code

Twenty Five days into the new year and I realised, I hadn’t posted on here yet. To remedy that, here is a short update post: Last year I was working on an Addon for Blender, more details when it is finished. Suffice to say I had the addon working and I’ve been using it for a while. I wanted to add some additional features and tidy up the UI and then perhaps release it....

Blender Gamma Node

This isn’t intended as a doctrine, just some food for thought For a while now, I have been using the gamma node in Blender as an alternative to the color ramp and the map range node. There are a few reasons why I like the node: It is light weight. It is a simple one slider does all node. The node inputs are easily exposed in a Group. I can use one Image texture easily to drive more than one input - see below....

Blender Edge Wear Node

Blender Edge Wear Node

This is a demonstration of how to create a Node Graph in Blender to make and Edge Wear node for use in Cycles. Step one: Create the node graph as shown above in Blender’s shader editor. Note the samples input this will be added next. Step two: Add a Samples input slot, so you can drive the Bevel node samples from outside the group. Step three: TAB out of the node group and then right click on the Samples input and Copy as Driver....

Blending Machine Parts

I have recently been watching a YouTube channel from a Japanese machine tool maker, which I find interesting and relaxing. It is also a great source of reference material for 3D modelling. For ideas and materials, I have been making screenshots like crazy as I watch through his demonstrations. If you are interested in checking the channel out it is here: @SwapLampJapan I hadn’t thought of using YouTube as a source of reference but as the quality of the video cameras improve I am able to get some really nice shots for reference....

Asset Surface Snapping Blender

When adding mesh assets, for use as a cutter for example, it is important to align the asset to the underlying geometry’s surface normals. This can be achieved by using the following setting in the snap options menu in the tool bar at the top of the Blender UI. This will snap the assets origin, as the center, to the surface of the target mesh, when using the CTRL key or by toggling the snapping option Magnet icon in the menu....

Blender Bits is Back

It is my intention to use the site for any Blender specific tips and tricks I find whilst using Blender. I intend it to be a very personal and refined site, not a repetition of the already wonderful resources available to the community. It will contain things I found useful, and think I might need for future reference. Your millage will vary, but I do hope someone else gets something out of it hence me sharing....

Blender Curve Manipulation Problem

If you find you are unable to move a curve handle in all three axis, it is probably due to the curve type being set to 2D. When you create the curve expand the Simple Curve dialog in the lower left of the viewport, or press F9: From here choose 3D and then, if you want curved splines, choose Auto in the Output Curve Type. The defaults are 2D and Vector and they may not be what you want for your curves....
