I just got a message asking if I could upload the pipes I used in the recent render, and while I was planning to release them the message gave me the kick in the butt I needed to finish making them 'suitable' for release.
There's some important notes with these. There was a lot of manual tweaking etc in the new render. The textures are procedural but they rely on baked maps to do the 'wear' patterns.
I used GrungeIt, so if you have that you can just re-bake if you modify them. If you don't I made the pipe quite long so you should be able to delete geometry to shorten them and re-cap the ends. I'm sure there are other ways but that should work without messing with the UVs.
These were all modelled by me so don't expect amazing geometry, but they should all be quads. The straight and T connector are low poly without subdivision so if you have simplify turned on they will look very very low poly.
Blend file is called BondagePipes.blend and is in the models archive for those who have access.
If you have any questions let me know.
