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.
- 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.
- Click the shading option arrow next to the shading modes in the upper right corner
- The lighting default is “Studio”. Change it to “Flat”
- The color default is “Material”. Change it to “Texture”
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.
The 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.
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 AutoMerge option and then just move one vertex over another.
In Blender 2.80, the AutoMerge option has moved. It is now in the Active Tool and Workspace panel under “Options”
Here are my go to settings for Blender when I am modelling for a 3D Print
To design in inches and export an STL file at the proper scale:
- In the Properties Panel, go to the Scene Tab.
- In the Units section, Change the Units to “inches”, the length to “imperial” and the Unit Scale to 0.0254.
- When you export your model as an STL file, set the scale to 25.4.
Photogrammetry is a cool technology, but it’s difficult to get a usable model. Most of the models I make have large holes or areas where the mesh is way off. Where the model is not way off…there is usually a tight mesh that isn’t required. Next…there are the shadows. Photogrammetry adds the lighting from your photo shoot to the model and this isn’t desirable (unless you are duplicating the lighting…which basically never happens). Continue reading
I got a drone for Christmas. I would make a Blender model of it, but it is hard to replicate when it’s 50 feet in the air, stuck in a tree. On the flip side…I’m not the only one who has lost their drone. I found one similar to this on the sidewalk one day. I have no idea where it came from and no way to fly it…but I can model and animate it.
