This commit performs both lossless and lossy compression on every .obj and .png in homedecor. The .png files were all 100% losslessly compressed using ect.exe and optipng.exe (more details below) at maximum settings. The .obj files were lossy-compressed so that comments were removed, trailing 000's were removed and all numbers rounded to 3 decimal places max. Blender exports at 6 decimal places but for minetest, 3 decimal places is the absolute maximum a person with anything under a 256K screen will ever need.
## Results
```
Original entire modpack size: 6343.5 KB
New entire modpack size: 5312.2 KB
Total Reduction: 1031.3 KB (16.3% less)
```
Please note that actual media size is likely more like 4,500 KB so media reduction is more around 20-25%.
## Details / What actions were actually performed
Used these programs:
https://github.com/ExeVirus/Compress-Objhttps://sourceforge.net/projects/optipng/https://github.com/fhanau/Efficient-Compression-Tool
Ran this command on every .obj: (fast)
```
luajit.exe compress.lua -f <file> -precision 3
```
Ran these commands on every .png: (slow)
```
ect.exe -9 -strip --allfilters-b <file>
optipng.exe -o7 -strip all -clobber <file>
```
Note that for future compression, I recommend only using optipng.exe instead of both. ECT can get better results but it takes a LOT longer and only ever saves another 1-2% of the file size. Not worth an extra 10-20 seconds per texture file in my opinion.
## Time spent
Roughly 2 Hours from start to finish + commit + PR
material only) and make it from 5 tar + 4 marble (both from
building_blocks).
If moreblocks is installed (and technic isn't), this node is routed
through the stairsplus component, and a recipe is added that uses
moreblocks' own tar node also.
some minor bugfixes here and there, also got rid of the spleef stick
and renamed the "faggot" to "sticks" and gave it a description.
needed this mod in homedecor for the marble and some other stuff.
Didn't make sense to re-invent that material yet again.
