Baking Textures in Blender

I just spent the last hour in Blender trying to bake a diffuse texture from a model created with photogrammetry to a lo-poly model created in Blender. I checked and double checked every setting. I went back to tutorials that I watched years ago. I looked for new issues that might be caused by the latest version. I finally found the problem.
The software I use for photogrammetry is Zephyr. It outputs the textured models in several formats. The two formats that can be imported into Blender or OBJ and FBX. I chose FBX. I chose poorly.
No matter what I did, I could not bake the texture from the FBX model to a low poly model.
When I went back to Zephyr and exported as OBJ, all my problems went away.

Exporting OBJ files with textures from Blender

This one drove me crazy. When I would post my models that I created in Blender and exported as OBJ files, people would complain that the textures weren’t included. And they were right.

I have found the solution. Before you export the file, use the “Pack All Into .blend” function. This can be found in the menu. Click File – External Data – Pack All Into .blend.

Pressure Gauge

I found this pressure gauge buried under the pile of un-used parts. I can’t image when I would have purchased a 10,000 psi pressure gauge…made in China. My guess is…I didn’t buy it. It’s not up to the quality my customers expect. It probably came on some equipment and we replaced it. It does however have a unique “Danger Zone” graphic on the dial. I figured this might have artistic appeal.

It was uploaded to CG Trader and I got my first sale 3 days later.

Residential Oil Tank

My day job has me designing an oil recovery system for a hydraulic coupling. It’s a complex oil system that uses a residential oil tank. I was surprised to find little in the way of online resources for such a common architectural 3D asset.

So I spent a little extra personal time on this model. I modeled the tank in Blender 2.9. It’s a 275 gallon Granby vertical oil tank. It is available at CGTrader:

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.

A collection of knobs

Collection of Knobs - 3D models

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.

Texture Painting

I was having a hell of a time this morning with Blender. I couldn’t get the Texture Painting to work. I searched online for a solution, but every answer seemed geared to someone just learning.

After struggling and not finding the answer online, I finally figure it out. The object I was trying to paint was in the “Local” mode. The local mode quickly isolates one more objects. It is toggled on and off with the “/” Forward Slash key on the keypad.

I toggled local mode off and texture painting magically worked again.
