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.

Today I received an air pressure regulator that I will be using in an industrial brake. The brake has a pneumatic powered oil pump.
I first made the model in Solidworks. It was exported as an STL. This makes a horrible mesh for Blender. Triangles aren’t necessarily bad, but long triangles with sharp corners are not good.
I recreated the mesh by over the top of the imported file and then shrunk it down on the surfaces of the imported model. I then created material map files. For this model, I made a diffuse map, a metallic map, a roughness map and a normal map.

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
I walked passed this cone the other day. I had some time to kill, so I modeled it. I created one with the dirt and then cleaned it up.
I spent last weekend out of town working the night shift. While I was waiting for my shift to start, I modeled the table lamp in my hotel room. The model is available on CGTrader.com:
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.
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
