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.

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.

Blender Quick Tip – Auto Merge

Update: 5/27/2022: They keep moving auto-merge. In Blender version 3.1.0 while in edit mode, the auto-merge has a convenient on-off toggle and link to the auto-merge settings in the upper right corner. These buttons are visible when the “Tool Settings” are enabled. To enable the “Tool Settings”, click the “Tool Settings” from the View drop-down menu until there is a check mark next to it.


When you move a vertex over another, many times you want the two to become one. There is a tedious way: Move the vertex and then merge. Or the easy way: Enable the  Auto-Merge option and then just move one vertex over another.

In Blender 2.80, the Auto-Merge option has moved. It is now in the Active Tool and Workspace panel under “Options”
