Title: ISS
Post by: Hannes on March 31, 2017, 02:19:23 PM
I found this beautiful model somewhere on the NASA website. Unfortunately I forgot where exactly it was. The only model of the ISS in high res I can find now is the .lwo here:
https://nasa3d.arc.nasa.gov/detail/iss-hi-res
Somewhere at NASA's I found the whole thing as a blender model with an extra folder containing lots of textures. However, it seems to be the same model.

When I first opened the model after I had converted it, I was blown away. It's incredibly detailed and I thought, man, this must have been a lot of work!
After I saw, that this model has more than 1300 (!) different shaders, I thought, man, this is going to be a lot of work!
Actually, this amount of textures is absolutely unnecessary. For example there are hundreds of similar plain grey shaders, sometimes one shader per bolt, so I tried to reduce the amount of shaders to be able to edit the whole thing.
It took me about two weeks to reduce the shaders to a total of 58. I threw out even a lot of those that contained texture maps. Some of the maps only showed simple colors, so this was easy to do.
I had to recreate some of the structures, because some of the normals were completely messed up, and even PoseRay couldn't fix it. Then I created some bump maps out of the existing ones, and I made a completely new texture map for the large solar panels, because the original ones were too lo res.
I had a look at lots of reference images and tried to make it look as photoreal as possible. The earth has some very high resolution texture maps. The cloudmap for example is a 43K texture. Additionally I added a cloud fractal to the cloud layer's depth modulator.

What a hardcore job! And what a impessive and good result!
An absolutely amazing job, Hannes! Congratulations!

And believe me! I know, what you did! I gave up exactly the same job a week ago!  ;D ;D ;D

I started with the single modules version. I think it was an idea from a time when no of my PC could open the whole model at once  ;D
It consists of 47 single objects which must stuck together. Rest is identically to what you told. I gave up after 7 Modules...

Wow Hannes, this is spectacular! I played with a bunch of different ISS models a year or so ago trying to find the best one, but never had one of this quality, detail, and realism. For the Earth textures, are you using the high resolution cloud map to mask TG clouds? Also, what is the bright white folded section on the right? Is that untextured or just very bright/exposed?

Title: Re: ISS
Post by: Hannes on March 31, 2017, 08:35:57 PM
Thank you all!
Oshyan, yes, it's a high resolution cloud map. I don't remember, how these white things are called (I'm not at home atm), but it is some sort of heat reflector, and looking at the reference images, it seems, it's some sort of white fabric (?). Even on close up images there is no noticeable structure, so yes, it's just a plain very bright grey shader.

Post by: Hannes on April 01, 2017, 02:35:38 PM
By the way, here is another very detailed one:
http://www.blendswap.com/blends/view/71861
The untextured mesh is free, so it might be interesting to play with it.
You need to register there, but it's OK. I registered a few months ago, and they didn't bother me with ads or stuff.

It's a Blender file. I opened it in Blender, and tried to export it. Unfortunately the main truss doesn't export, no matter what I do. I selected all parts including the truss, but when I open the exported OBJ or even 3ds, the truss is missing. Any Blender specialists out there?
Title: Re: ISS
Post by: masonspappy on April 01, 2017, 05:27:02 PM
Hannes, pretty sure I'm not what you would call a "specialist" but I'll download it in a bit and see if I can figure out what the problem is.
Title: Re: ISS
Post by: luvsmuzik on April 01, 2017, 06:13:46 PM
Make sure it is a mesh and not a curve that has not been converted to mesh also. (By no means a specialist either)
Title: Re: ISS
Post by: Hannes on April 01, 2017, 06:49:42 PM
Thanks in advance!
I also opened the object in PoseRay. The truss is missing, but the rest looks good. But there's an issue with normals after you reimport the mesh into other apps, even after recalculating them.
In 3dsMax there are some flipped normals. In TG it looks good at first sight, but if you look closer you can see, that there's something wrong with them. Even with the same shader they look different somehow.
I read, that this occurs quite often, when you export meshes from Blender.  :(
Title: Re: ISS
Post by: luvsmuzik on April 01, 2017, 07:36:27 PM
Can you identify the mesh as a single mesh, or is it about 50 in a group to make the truss? You might try selecting and make a new group then join to whole again...

If you can identify it as one mesh, could you, in a new file, append that mesh and then export as a new object, just the truss?

There are all sorts of professional methods which I do not know, but I too cannot get an arch to stay attached to my hotel object....it is a simple mesh but made in a quick easy method that obviously does not export well. I am sure it is my method of joining it, as it will export as a separate mesh just fine.

I am sure you already tried all this simple stuff.
Title: Re: ISS
Post by: Hannes on April 01, 2017, 07:53:34 PM
Actually I feel a bit lost in Blender. I only installed it to convert Blender objects. Otherwise I have absolutely no experience with this program. I'm sure it's fantastic, but not very intuitive.
Thanks for your tips! I'll try to find out how to do what you mentioned.
Title: Re: ISS
Post by: masonspappy on April 01, 2017, 09:22:17 PM
ok, I've attached two renders of the  ISS, with no modifications made to the Blend file.
Hans, can you please reference the ISS1-Blender file below and tell me what's missing?
I've circled what I "think" is the section you referenced.
Thanks.
Title: Re: ISS
Post by: Hannes on April 01, 2017, 09:55:48 PM
Yes, that's exactly the part that's missing!
Title: Re: ISS
Post by: masonspappy on April 01, 2017, 10:00:21 PM
ok, could you re-download the blend file  from the link you provided, export as OBJ and try to render in T4 again?
I didn't make any changes but it rendered ok for me in the second image. Might have been noticed and fixed recently.
If that doesn't work I'll send you the OBJ file I just created and you can see if that renders correctly on your machine.

Title: Re: ISS
Post by: Hannes on April 02, 2017, 01:14:19 PM
Thanks again, Masonspappy!!! I gave it another try, and found what was going on. The first time after I had exported the .obj I opened it in PoseRay and got some sort of a giant bathtub, which looked weird, so I converted it to .3ds and then back to .obj, and in the end the truss was missing.
So I exported the file again from Blender as .obj, opened it in PoseRay again, and took a closer look. See attached image, what I got. When I imported it into TG, the structure was there too.
OK, now I saw, that everything was there, including the truss, and the extraordinary orbital bathtub. I could easily delete this part in 3ds Max. Still no idea what this is. I hope, that it's no blown up representation of some crucial part, that's now missing, but it looks OK so far.

In some areas this mesh is more detailed than the NASA one, but there are other parts, where NASA is winning. It's probably way more complicated to texture this one, since there is NOTHING set so far, but maybe I'll give it a go.

Post by: bobbystahr on April 02, 2017, 06:57:14 PM
Well, at that same page ther are downloads for the ,fbx  and the textures, .fbm so I dl'd em and put everything in an ISS folder and opened the .fbx with DAZ Srudio 4 and tickety bo it appeared fully textured in DAZ but after exporting to .obj I tried opening it in TG4  and it loaded fine but clicking show textured crashed my TG4 with 16G of RAM..wtf is up with that? Trying to load it into PoseRay but it's been struggling with it for at least 5 min. so far....finally on Loading model.... I'll post what happened later.

was still trying to load in PoseRay at 15 min so I cancelled, managed to get it back in TG4, checked the first material in the left panel and it was there so I tried a render and it got to starting render and just went unresponsive...good thing I am not really wanting to use this model but was just curious I guess. But DAZ does seem to be a handy alternative for those with it when .fbx comes up.
Title: Re: ISS
Post by: Hannes on April 02, 2017, 07:05:24 PM
Bobby, you're talking about the NASA model, right?
As I wrote,  there are more than 1300 shaders. That was the first time, TG refused to render. It loaded, but after I hit render, TG crashed on my machine as well. It worked, after I reduced the shaders to 58.

Don't know if this applies to you, but I noticed that when I imported some of my Blender-made models into 3DS MAX, pieces were missing. I had to tick a box to force all parts to appear.  Maybe something like that is happening with you as well?
Frankly, I think much of this stuff is magic..... ;)

Yeah, I sussed that out, as I said I was just curious, and as I've no MAX I'd have to beg the model from you were I to want/need it but I'm terribly terrestrial of late it seems...and speaking of terrestrial I inspected my yard as a flash of colour appeared at the foot of my peonies and whoop whoop, my prairie crocus' have risen and bloomed...this year I caught 'em before they disappeared.

Here is a (quite large) comparison between the two models. Both have the same plain grey shader applied to see nothing but the geometry.
It seems, the free model by Chris Kuhn is even more detailed. I just started to tear the model apart to see, if it's doable to texture it. The textured mesh costs $159,99. Not too expensive, when you think of the work he put into this.
Title: Re: ISS

Oh wow, even *more* detail! Although Chris's model is missing some modules, eh?

Title: Re: ISS
Post by: Hannes on April 03, 2017, 10:01:29 PM
Yes, as far as I remember he was talking about the actual configuration. There seem to be changes over time.

I'm thinking about combining the models... Maybe, if texturing isn't too tedious...

I had a look at Turbosquid. There is only one model, that's better than Chris's or the NASA model, and it costs $1299,-. which is justified, I guess. But there are some ridiculously expensive models. I don't know, what these people are thinking. These meshes are crappy compared to the mentioned free ones.

NASA's website has some awesome resources. Some nice asteroid models and lots of other great resources.

Gotta love these space images, and hate those insane amount of textures/shaders. I had a bake of Hubble in C4D sit remapping groups for 6 hours (and achieve 3%) before I just decided to stop it as I think the heat death of the universe would have come first.

Seems that Chris model has not more details. It seems to have different details. In the Nasa model many of the rivets and metal struts on the modules are just general bumpmaps. Chris model looks as if these details are real objects. (or do I have another version?)

These textures are in a central folder and I have to use them for each module - I copied all what I needed to each single module folder:
[attach=1]
After 8 modules I gave up (for the moment :)  )


159 bugs is ok but not cheap for just kidding around with it like I would do  ;)
Title: Re: ISS
Post by: Oshyan on April 05, 2017, 04:32:53 AM
Yes, the ISS has had new modules added (and planned but not added) over time. Various models represent different stages of actual or planned deployment.

And yes I remember the $1300 Turbosquid ISS model. It's certainly a lot of work to create it, yet somehow that still seemed like a crazy amount of money to me. :D Especially when you see the detail level of the e.g. Star Destroyer, etc. models people share for free...

Title: Re: ISS
Post by: Hannes on April 05, 2017, 04:35:01 PM
In the meantime I managed to get the solar panels and the Destiny module of the Chris Kuhn model textured and edited a bit, after I isolated all the different parts from each other. I took some NASA reference to see which is which (and how they are called). Still a lot of work, and unfortunately there are no material channels in this model. The NASA model had some. 1300!
Some sort of masochism....
Title: Re: ISS
Post by: Hannes on April 05, 2017, 04:36:31 PM
By the way, I created some sort of aluminium shader with a very subtle displacement using a very very small PF as shader, since blurred reflections are still buggy in TG.

Title: Re: ISS New
Post by: Hannes on April 23, 2017, 07:15:09 AM
Thanks Martin,
yes, I will. I just finished to render the Kuhn model. As I wrote, I had to separate the whole thing, since it was just one model, no groups, no whatever and then isolated each single part to texture the whole thing. I downloaded lots of reference images and tried to make it look like the real thing. For some parts I couldn't find any images, so I had to use my imagination.
Since the two models (NASA and Kuhn) show different stages of the configuration, I took some parts of the NASA model and sticked it onto the Kuhn model. I don't know, if this is correct, but I thought it looks cool.
Title: Re: ISS New
Post by: Hannes on April 23, 2017, 08:51:39 AM
By the way, there is some minor postwork: a little chromatic aberration, saturation and brightness, and some glare which can be seen on some of the reference images. This glare effect could have been done in TG probably, but testing out the amount of bloom until it's OK takes a lot of time, since you have to render the frame each time completely.

A last (?) one. I edited the Soyuz module and added some stuff (some more details and there's some sort of grey cover wrapped around it on the reference images).
I tried to recreate an image like those you can find when you google ISS NASA. This time there's no photo. Everything is in the scene like it is. But I did some minor postwork: some color grading, a little chromatic aberration and some sharpening.
