Resistor Collection

Wasting time is such a waste (duh). Once you have modeled an object, it is great to have a library of part. The question is…how do you organize them in a way that you can find the part you need and easily import the part into you new design.

Today was my first attempt a building a library in Blender. I created a Blend file with 57 different configuration. There are 19 different resistance values (as indicated by the resistor color code) and each resistor is saved in 3 different mesh forms. The first form is straight. The 2nd form has both terminals bent at 90 degrees for horizontal mounting on a breadboard. The 3rd formation has one terminal bent to 180 degrees for vertical mounting on a breadboard.

Picnic Table

3D models can be from your imagination or from real world items. Today’s model is from the real world.

I modeled a picnic table from one that is available at Home Depot. I used the online photos in fspy to get the camera position. The fspy camera positions and the phone are then imported into Blender with an add-on. I then drew and aligned picnic table elements in Blender. When it was all done, I scaled it to real world sizes and added weathered wood materials. The materials were created with overlapping UVs. This allowed me to get decent resolution without using huge images.

The model is available at CGTrader.

Collection of Knobs - 3D models

A collection of knobs

2 posts in one day. That’s a first.

I’ve been working on this collection of knobs for a while. I thought it would be simple. But like most things…simple is rare. I ran into difficulties controlling fillets in meshes that were sub-surface ready. The model would look good until the sub-surface modifier was added. You can get some strange looking artifacts if you don’t have good topology.

The collection of knobs is available at CGTrader: https://www.cgtrader.com/3d-models/electronics/other/collection-of-12-knobs

 

Pedestrian Crossing Sign

I went for a walk with my wife and dog yesterday and came across a pedestrian sign in the middle of the crosswalk. This morning, I checked CGTrader and didn’t see any similar signs. I made a graphic in Photoshop and a quick mesh in Blender. I have posted the model on CGTrader for $2 if you are intersted

Soccer Goal

I created a soccer goal in Blender a while back. Most of the goals I see available on CGTrader have nets that look like they were strong tight and frozen in place. I tried to correct creating a mesh and using the fabric simulator to create realistic slack. I then removed the faces and converted the edges to curves. I also added details like the corner brackets and the nets clips. Continue reading

Power Switch Model

A new model has been posted on CGTrader. It’s a rocker switch with power on and off markings. It was modeled in Blender 2.80, but it was rendered in the Blender 2.81. Then new version of blender has a noise removal node for the compositor. It works great.

Render 2.pngThe new noise removal node is not available in 2.80. Go to the Blender download page and scroll to the bottom.  Click the “Get Blender Experimental” button and download. You will get an compressed file. I created a new folder (c:\program files\blender\blender2.81) and extracted all the files there. Then just double click the blender.exe file to run.

To use the node, enable a few render passes that the node uses. Go to the View Panel and expand the Passes section. Enable the Normal Pass and the Diffuse Color Pass.
