This is a runner that I created for background decor for my local Sci-Fi rpg group's game. Originally intended to be used as a catwalk/flooring, the underside can be used as tubing, conduit, or rebar, depending on the texture that is applied to it. In the examples, I've used metallic textures, but a rubberized texture would give a different feel. The model is extendable, can be duplicated, and has a support mount for the tubing on its underside. I've included shading examples that allows me to extend the length of the model without warping the texture.
The example textures (not included) used in the pictures I give credit to 3dtextures-dot-me (sci-fi-hose-003) and cgbookcase-dot-com (Metal Weave 02).
