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 ![]() ![]() ![]() ![]() ![]() -------------------- |

The shadow definitely adds realism. However, it looks like you rendered a shadow layer and placed it on the ground, but the rover parts that should also be in the shadow are illuminated too much (the rover body beneath the solar panels for example). The shadow on the ground will also have to match with the shadows that fall on every rover component, in both direction and darkness, or there will be a visual disconnect that will instantly give it away. People who haven't done 3d rendering may sense that something isn't right but may not be able to tell exactly what's missing. The guidance you get here from Doug for example will go a long way, so soak it all in as it will only help you in the long run.
![]() Some 13 years ago I had fun modeling and rendering Anakin's podracer (link). It took me a while, and in the process I learned a LOT. While it doesn't even remotely compare with the effort and detail you put into it, the end composite was rather similar in that it took me many retries to get it believable with shadows and lighting in the right directions. Later I created some product images for the company I worked for, and they were almost indistinguishable from real photographs. Also, consider adding a small copyright notice to your images you post. Just saying... |

However, it looks like you rendered a shadow layer and placed it on the ground, but the rover parts that should also be in the shadow are illuminated too much... ..the shadow layer correctly shadows all the parts of the rover, not just the ground, if you compare it to the original integration you will realize this. The body is reflective thats why it seems to be lighter.. edit: once again I realize that something went wrong, checking my layers now, and while the shadow layer is right, the illumination layer isn't. GRRR. Next render will be perfect.. edit2: looks like there's a serious restriction with the program I am using. Seems like you cannot use for lighting both physical sun + hdri. So I either have to add a new light source and re-render everything from scratch (which is a no-go because it takes soooo many hours) or what I am doing now. I am rendering using the sun as a source, then overlapping with the original render I had to get color/hue and then add everything else. Hope all goes as planned. To be honest, the render seemed a bit strange, but hey, some things in life seem strange as well like sometimes the car reflections in real life seem 'unrealistic', I thought the program took care of everything but looks like this restriction made it seem a bit odd in the end. Anyway, let's see what happens -------------------- |
