Ah yes. I was supposed to type them instructions. I don’t have a dog, so I have only myself to blame for not typing them in again and send them.
The thing that stood out most to me was your use of texture mapping. For instance with the tubes you use Cylindrical mapping, which in itself is a good thing. Except in some cases you have the cylindrical mapping placed such a way that essentially the cylinder and your tube are at a 90°.
Also, you’re using the Ray projection, which doesn’t really work in Raytraced/Rhino Render.
Orienting the texture mapping properly, more closely matching the geometry you’re mapping on, and uisng closest point projection should yield you results that work for both Rendered mode and Raytraced/Rhino Render.
In the shot below I made a copy of the original vertical pipe, moved that to the back, and redid the texture mapping on the one in the foreground. It has now a cylindrical mapping that is closer to what the geometry is, and closest point is used. You can see that the Rendered and Raytraced viewports now agree.
Apologies for dropping the ball on this.
Addendum: I forgot to say that since your textures are only simple lines you can do your pipes even with simple planar mapping. If you then want to optimize the texture you could make it just one pixel high or wide as well, since the pixels just repeat in that direction
And a version with just the simple planar mapping,ever so slightly faster (simpler math)
