Blender Tip: Mesh to curve

Here is a Blender 2.81 tip I had to re-learn today.

I started a new mesh and created a string of vertices. After I bit of work, I realized that a curve would be much better. It is pretty straight forward to convert a mesh to a curve, but the curve is little more than then the mesh by another name. What I was looking for was the vector handles to smooth out the corners.

The trick is to convert the new curve spline type to a Bezier curve. The vector handles then appear. Continue reading

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

Blender Quick Tip – Photogrammetry Lighting

Photogrammetry scans already come with their own lighting. When using these scans in Blender, you can get a natural look and speeds up Blender with a few clicks.

  1. Put the 3D viewport into the solid mode. You can click the solid circle in the upper right corner or hit the “Z” key and then slide your mouse to the right.
  2. Click the shading option arrow next to the shading modes in the upper right corner
  3. The lighting default is “Studio”. Change it to “Flat”
  4. The color default is “Material”. Change it to “Texture”

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.

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.

Photo Real Renders vs Photos

Sometimes it hard to tell if a product shot is a photograph or a CG render. Part of the problem is the quality of modern rendering. But I think there is an overlooked aspect. So many photos are “Photoshopped”. People have become accustom to seeing perfect pictures….no scratches and no dust.

Photographers might want to leave some of the imperfections in their shots.

CG Models

I created a CGTrader account years ago. My first submissions were all free. I wanted a way to give back to a community that had help me learn Blender. And then one day I saw a post on the user forum. Someone was complaining because the models were under priced. They were seeing a drop off in sales and believed it was because more content was being offered for free or for a very low price.

3″ Check Valve

I posted a 3″ Swing Check Valve on GrabCad today. Within a couple of hours, it got 6 likes and 3 downloads. And if you didn’t know…all downloads on GrabCad are free.

This valve is manufactured by KITZ. It has class 300 raised face flanges and the body is made from cast stainless steel. The face to face dimension is 12.5″.
