hello.. i am trying to model in 3d the mars rover and can't find the correct material, so I was wondering whether anyone in here has access to more information than I do and cares to help.
I am looking for detailed pictures of rover parts from all sides (top, left, right and bottom). I am attaching a few pics for the members to see the progress of my work. Trying to be as accurate as possible. Process is really slow since I have to make stuff out of bad reference pics I've tried collecting material from the nasa site, from raw images coming from the rover, from roobtics' sites etc, but couldn't come up with the correct reference i am seeking. if anyone cares to help, please do so ![]() ![]() ![]() ![]() ![]() -------------------- |

Hello everyone, new render for your eyes.. here with morning lighting..
![]() I spent almost a full day making the cables look right, I double checked them and this is the best result. It may look a bit too shiny in a few parts, but trust me, it's as good as it can get. Already started the HGA, expect results soon.. edit: for people interested two HUGE (5400x3038) renders on my site in black and white backgrounds respectively: http://www.nicksotiriadis.gr/mer-white.png http://www.nicksotiriadis.gr/mer-white-2.png -------------------- |

Hi Scooterlord, like everyone else here I love all the details like the manufacturing scratches on the metal surfaces. But I think I saw those scratches also on the flexible flat cables, on some renders... I don't know what flats NASA uses, but in my experience those cables are smooth and shiny even after quite some use... Maybe it would be better to make them smooth? What do you think?

Well... first of all it's not the same scratch texture, looks like it's the same but it's not
![]() ![]() Left to right, top to bottom we have, ribbon in the idd, hga, mossbauer's ribbon, idd ribbon on mars and extreme close-up of the idd's base. All of them being great examples (and I am grateful I found images of THIS quality) but the last one is the best. As you can see they are not smooth at all. The renders that show 'scratched' cables are extreme closeups, if it was a bit further away you wouldn't be able to tell there's something there, it will make the surface seem 'strangely' reflective as it shows in most of the mars rover reference pictures. In the specific render that the scratches are shown (the idd closeup I posted before) You see 3 parts of the ribbon, left, center and right side. They all have the same texture on, but look how different they show according to the light source reflected on them. Just notice the right part of the cable, isn't this what you were looking for? Let alone these are TEMP renders, not lighted properly, just a sun source with too much intensity. Last but not least, I have too much trouble making out the colors in different reference photos I have. Some reference is washed out, some is indoor lighted, some outdoor lighted. Sometimes is seems red-ish, sometimes yellow-ish, other times brown-ish. I still am not sure about the ribbon color, that's why I ended up in something in between all of the above. Moreover, the cables. In most photos they seem yellow. In others orange to red. In 99% photos you can't make out that they are actually transparent and more than one cables are inside of them, but I tried to replicate this as well. I want to hear about everyone's opinion but, trust me, I am way too thorough to leave such mistakes occur ![]() -------------------- |

Hi Scooterlord, first of all, thank you for your reply.
Of course I have never seen "live" NASA cables, so my experience was with everyday cables - the ones that you can find in almost every electronic device these days. Well... first of all it's not the same scratch texture, looks like it's the same but it's not ![]() Left to right, top to bottom we have, ribbon in the idd, hga, mossbauer's ribbon, idd ribbon on mars and extreme close-up of the idd's base. [...] As you can see they are not smooth at all. [...] I hadn't seen those pictures before, and I agree the cables don't look absolutely "flat"... but I'd say what I see are the "bumps" due to the dozens of parallel copper tracks running under the lamination, and not "random" manufacturing scratches... That said, I trust your eyes and judgement, and I fully also appreciate the fact that the only way to be sure either way would be to hold the actual piece in our hands! ![]() Cristian |
