I have not seen a problem with that, but looking at the image you have posted it looks like the edge of the K is a smooth shape but the red diffuse texture is not covering the whole of the front UV - allowing some gray to show. The initial cause of that could be that the path is just outside the red area when traced.
It should be simple to fix by editing the texture.
For example :
If there are any gaps - brush them in. If all the front texture is the same colour then just select the whole square texture and fill it with the required colour.
Can you go to Front Inflation Material - Properties - Edit Texture and take a screenshot.
Ok. Here are a few steps I've done that I hope help to solve this.
I did as you suggested: go to Front Inflation Material - Properties - Edit Texture and take a screenshot.
Here's what that looked like:
The red area is the true shape, as you can see in the next image. The shape is a smart object that looks like this:
So if I fill the area with red, as in your screen shot, I have to rasterize the smart object:
then fill the paintable area with red:
This is the result:
How is the UV overlay generated? It seems to be a rough trace of the Smart Object or path. The final rendering seems to be based on the UV overlay and not the Smart Object. Can I replace the UV overlay with the more accurate Smart Object?
Is there a way to adjust or tighten the trace of the Smart Object through a preferences setting?
I can't seem to find anything about this in searches. I've had the problem show up on different computers and several earlier versions of the Photoshop. There is a lot of nice work being done in Photoshop 3D, so I know that there is a fix for this or I'm just doing something wrong. UHG!
Any help is appreciated.
Now that I can see the screenshots - I see your problem is coming from the use of a smart object - which effectively makes it a pixel based image and the extrusion is no longer based on the vectors - but on Photoshop creating the vector from the rasterised layer - which includes anti aliased edges.
Below is the top corner of a simple text letter K .
1. Extruded from the text layer
2. Converted to a shape layer and extruded
3. Put into a smart object and extruded.
The third method (the smart object) shows the issue you describe.
To keep it crisp - use the vectors (i.e. paths and shapes) to create your extrusion, rather than relying on Photoshop to create an edge from an aliased pixel layer (which is what the smart object presents).
I hope that helps you
Thanks for time and attention to this Dave.
I'll tinker with this some more and keep that in mind for future 3D builds. Maybe this would be something to have Adobe developers work on for a future upgrade.

Now if only I could control what Adobe do ......
You see a similar thing when you make a path from a selection. Sometimes it doesn't quite get it right.
