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.

Air Pressure Regulator

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.

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.
