The maps actually fit the profile of the Von Braun better than I thought it would. Nice to see someone finally do this for SS2 after seeing UUW and SS1's complete maps.

Sorry, uploading the textured version doesn't work. Too many materials.

These screenshots are the best I can do.

Had to split all the levels into their own file to even open them in blender.
Here are the eng1, eng2, medsci1 and medsci2 levels. See if you can do something with them. I will give you the rest if so. Don't want to waste time exporting and reexporting every level.

In blender the textures fade to white, but that is only a material issue.
It might save some work & bits if I use the original geometry and textures files. The modded texture files are usually 2x - 4x as big.
I'm curios how you are planning to merge 2200 (Edit: probably less then that. Just the amount of materials in my project, which includes everything.) materials. Hopefully not per hand, right? 

I've seen your name as the name of some texture folders. Kinda cool to talk to the person behind those.

You are right. Damn assumed the whole time they came packaged.
 

I can upload my fam folder, if someone wants it. Its like 120mb

Wow. Good job looks awesome.
Since you know how to use unity, I could just give you all the level files as a unitypackage. How about that?
For the final version you may want to remove the dev-rooms. The unseen rooms where things get stored for cutscenes and stuff. Or you may not, IDK what would be better.

I don't see the glitches in the image (if there are some supposed to be there?)

Maybe a unitypackage wasn't such a great idea after all. It took 30min to create and is about 1/4 GB.

You can try importing it, but expect it to take like 30min. Its probably caused by the 10k small meshes that are included. Level meshs get split into a ridiculous amount of meshs (~2000 per .mis).

I might look into reducing the amount of meshs created, if you can't work with it.

Alright, I was able to remap all levels almost without any visible glitches.

There are some problems with original cell meshes like default materials without a texture in some places (water, and a lot in earth) and caustic texture instead of terrain everywhere where water reflection was applied.

Some maps have better texel density than others, rick1 is definitely the worst. In those cases it would probably be better to seperate level into smaller segments.
For now I ended up with 1x 4096x4096, 5x 8192x4096 and 15x 8192x8192 textures (+2x 8k for station and earth maps). That is a lot for RAM and VRAM and I don't know if Sketchfab can survive that.

I read somewhere that Sketchfab automatically merges materials if there are more than 100 detected. I've counted around 560 unique materials for everything except station and earth. I wonder if premerging cells (but without duplicating materials) before upload would help the process in any way.

Don't get discouraged by the size of the zip, if you load up all the models and textures I provided (preferably with a lower imported resolution for starters) it's actually a lot easier to render not only for Unity but other 3D editing soft as well.
It's all those cells and individual materials that generate a lot of drawcalls.

I did a quick test in Sketchfab and it seems to be working! I didn't arrange the levels in any way for this test.

But it's definitely squeezing VRAM on GPU as the total uncompressed size of all these texture is about 4,5 GB.
I wouldn't be surprised if some people would experience browser crash after opening this but I think it's worth uploading @Hardkern.

Hmh. The total size is now twice of what it was before. I think we are moving in the wrong direction.  I'm gonna try an approach of my own soon. Thinking about creating a texture atlas instead of creating a super texture with lots of repeating information.

I have a feeling for that you would need to find the largest common tiling area of a specific material and put that into a square on an atlas and then remap all the geometries into that tile. Otherwise I am not sure how the tiling would work, because majority of level UVs are spread across many tiles of one material.

Btw, at what company are you working with unity? Game related? Is it good?

I work at Black Eye Games. It's been a one giant well of experience for me. Learned a ton about Unity, graphics, shaders and coding in general.

Yeah, it might be worth trying just merging all meshes with materials.
There still is a bit smarter way to merge everything and minimize repeating information, something like I mentioned before about finding largest common tile for each material (within level, to be safe), but it's a lot more complex and would require time to code.
