I would definitely like help on how to model a rag. I'm sure other people would like that too. but if you don't want to post something here, please PM it to me :D |

Quick and simple method - plane, quad divide like crazy, scribble over it with the displacement brush.
Not very refined but a 'quick fix' method. |

Excellent demonstration of a 'rag' here. :)

WWotW almost had my technique. I used SoftPaint with the Grab 1D settings. With Grab you can get some folds into the material.
I used a cube with the height set to .001. After I shape them up I'll apply one layer of SS.
Remember in a Service Department the rag should look discarded or dropped while working. These examples I quickly kicked out for you
but if I was doing a project I would spend more time greasing them up by working with the texture..
I hope this helps. They are a lot of fun to make. |

OK - I moved the grime on the floor to the edges only... How does this look?

Looking good with the grime. The rag is kinda weird right now. Where did the two colors come in? Mess it up a little more and also grab the edges to deform so it doesn't lay perfectly flat. |

You may want to hang the range over the long end of the tire iron. Like he tossed it down after he was finished.
I agree with Steinie, about the edges being too square and the colors weird. The rag should already have a UV map if you started out as a plane so, best is probably a light yellow-gray fill and then speckle paint some stains and grim smears on it. To get the fabric texture you can use a stock photo of some cloth and blend it into the image, or make a brush out of it and use the burn tool to darken the texture into the image. Guess it depends on the paint program you're using.
For a simpler quick'n'dirty map you could try a color fill in the yellow-gray, then blend a noise layer, smudge some yellow and dark brown on it and call it done. ;) Working photo sampled texture in would be better though. |

If you've got a digicam you could go and check out some real auto workshops in your neighbourhood. Sweet talk a mechanic into letting you take some reference shots or even make phototextures (something I hope to do more of since I recently upgraded my old 2 megapixel camera to an 8.3 Fuji with 10x zoom. Not overly classy but it takes nice pictures.
Many of the auto workshops I've been in have painted concrete floors and a wide variety of different types of stains, oil, water, petrol, anti-freeze and so on.
I mention this because your latest floor looks too clean now to my eye. |

I was thinking that it looks a bit like a DIY garage so maybe it's a home garage?
Ah that reminds me, an alternate floor idea would be to use black and white diamond plate tiles.
Here's some reference images:

I've done so many diamond floors that I want something different.
right now, I'm working on my retractable air hose... ran out of time for today, so I'm going to bed with it only half done.

This will have to be it until Sunday... I have to go to bed, get up early and drive to the parent's.
I never knew how hard it would be to make a metal guard to keep the hose from shredding on the metal. :D

Pretty good! The hose wrapping around the tube looks a bit much too regular though. But if it's mainly for casting shadows, I wouldn't worry about it much and good textures can help too. Just remember to make your hose to hang more organically after you get it UV mapped and textured. |

Well... I've done with the hose. It's taken 20 hours total, and isn't even the focus of my scene ;)
I dirtied up the center of the floor a bit while leaving the edges dirtier and will work on my rag a bit more later on. Apparently a blue rag with rust staining was the wrong way to go for the coloring. I'll figure something out for it after I get it to bunch up right.

OK... the floor didn't look good yet, so I changed the one of the masks and I think it looks better.
as for that rag... HEY!! if you click on both mouse buttons at once, you can move it along the x-y axis instead of just moving along the Z!
hehehe - still learning things. :D
How does it look now?

This is looking so much better now. Couple of things thoug, if I may... The main floor texture is, well, odd. Looks more like a kitchen work surface than a garage floor. Try some of the amazing Simbiont concrete shaders, that'd make a world of difference. If you're using Vray then try some sort of concrete tex map.
The one thing that will, in my opinion, make the biggest difference is changing the colour of the toolbx. It's camouflaged against the wall right now. Red or blue are the most common toolbox colours (with red being the more dominant for pro use) why not try a paint texture in one of those colours? It'd make a stand out rather than hide away.
If this is a 'pro' garage then the toolbox would more likely be on top of a bench or a two tier (twice as high) to save the mechanic bending down all the time. Just an extra thought to throw into the pot. |

I will try blue, but I'm not sure. I'm still trying to highlight the tires, not let them fade into the background. That is why I used stainless steel for the body of the tool chest, and made it a shorter one. I'm not too happy with the floor either, and will probably increase the texture again, as I felt that looked better. |

Me again :). I'd have to agree with TheWickedWitchOfTheWeb on the floor texture. Looks more like linoleum found in a house rather than on a shop floor. Who hangs their calendar that low? Your wrenches look awfully 'flat' to be combination wrenches. The end that's rounded is normally at an angle, providing clearance so you don't bust your knuckles on stationary items when applying the torque necessary for loosening and tightening bolts and nuts. Keep up the good work. |

Man, that's some seriously saturated blue...
Maybe adding a corkboard with business cards, repair bills, etc, tacked on it would help fill the empty space on the wall above the toolchest?
Also doesn't your air house need to attach to an air pump?
I think the rag would look better not so close to the wheel of the tool chest. The shape is better but I think it can still be improved.
You're almost there, keep at it! :D |

don't know about a chalk board above the tool chest, but maybe I can put some sort of tire chart there instead.
you will notice that the lead to the air compressor is ready to be attached, but I chose not to do so at this time, because I didn't want to have to model the compressor ;)
the rag is not close to the wheel, it is actually draped across part of it. :D It's a bit crusty, so when the mechanic threw it down, it kinda slid across the floor and stopped there.
For obvious reasons (texture on the floor) I'm not really showing much of a close-up. :D

The rag looks a much better from that angle! Hmm... maybe it would be better draped over the tirebar or the other side of the wheel so that it's more obvious that it's draped over the wheel from the view of the render?
Interesting idea about the tire charts. :) Would be a lot quicker to model and texture than a tackboard with lots of paper things stuck to it... ;)
I was thinking that you wouldn't have to model the air compressor, just have the hose go off screen and maybe attach it to a cylinder shape so it casts a correct shadow and reflection. |

Everything Jack said! Justify it it how ever you want but from the viewing angle of the render the rag doesn't look how it does from that side on close up. It's a great texture on the rag btw but blue? A dark grey with darker oily patches would be more realistic.
Now, the toolbox... yes, it does stand out a lot better now it's coloured but whatever shader composition you've used doesn't look right (unless it's meant to be a plastic toy?). A scratched metal texture map would be a better way to go, certainly to inject an added level of realism that it's currently lacking compared to everything else. It needs beating up, they get scratched and dirty. Are you using vray or lightworks? |

Actually, shop rags come in white, red, orange and blue. But not gray. My local garage uses blue, so I went with that. according to the mechanic, the brand that his shop uses are color coded by amount of lint that they produce. Blue has the least amount of lint. |

Actually, I spent many, many years working in the motor industry and the average workshop industrial rag was a dark grey but that's beside the point. The colour of the rag looks like heavy duty workshop paper towel but the texture and folding implies cloth. It's not the actual colour that's in question, more the shade. |

Man, you make me laugh!
Well, I don't hang out in workshops much, but I can certainly imagine a grey rag (i.e. formerly white or near white but no longer) with oil/grease stains... only have to look at my dish-cloth... ;) |

Also keep in mind that when picking the color for the shader, that even "white" objects aren't white! They almost always a shade of gray. ;) |

I need to add more charts to the wall.

biggest problem is that any picture I find online, I have to re-do because of scattering issues. |

Thanks jack... I try to keep improving. :D
the wall to the right just looked like it was going nowhere, so I put the door there. Then I had to model a knob for it out of the shot to get the right shadows. amazing what you have to do to get the lights and shadows done right. I also tweeked the calendar because it was looking too dark and matt. Then I decided to see if the air hose was too large. Any comments?

I'm feeling that I need to do the air hose somewhere between the two sizes... |
