I downloaded a file from 3DWH, and it was a bit heavy for the model (a rolling shade). I then cleaned up the file by reducing the geometry. Everything was going well, and I was so happy with the result that I added ‘OP’ to the file name for optimization. But when I checked 3DWH again, to my surprise, I found another model with a smaller file size. .
Then I dove into the new file and discovered the following: it probably shares the same origin as the file I downloaded first (both have the same Dutch names for groups and components). My original file has 71% fewer edges and 69% fewer faces, yet the file with less geometry is 171% larger in size (KB).

I’m a bit disappointed because I’m not sure how to proceed with optimizing my models. It seems like I’m missing something. Can someone please help me understand what’s going wrong?
Here are the files, if someone wants to look at (texture removed).
high poly count (geometry) can make a file heavy and/or slow. but in order to make the file heavy you need A LOT of geometry, millions and millions.
think of geometry like pages in a book. doesn’t matter if we’re talking big or small pages, if your book is 10M pages long it will be massive. the model could very well weigh north of 10MB
on the other hand, if you make a simple cube and apply a10 MB material on it, your model will weigh about 10MB. even if it’s just a cube.
that’s why on the 3d warehouse we can’t give you specific good rules to follow.
is a 100K polygon 5MB model of a chair worth it ? well if you’re only modelling a room maybe, if you’re doing a whole building probably not.
Thank you all. Sorry for my late response, I wrote it but did not send it, since I had to rush to the hospital where my brother had a serious operation but thank God everything turned out well.
@numerobis Both models were saved with SU 24, and @rtches only have 1 material (‘Default Material’). @ateliernab the main difference between the models is in the Bead chain: the 3DWH file is made up of 258 groups of beads with 840 entities each, while the XPX OP file has 208 components/instances beads with 120 entities each. I also understand that depending on the use of the model, its modeling should be adjusted, like @mihai.s’s model, which has reduced the number of beads and faces that are not visible; I will follow this model. My main concern is understanding why the file with less geometry weighs more than the other one; I don’t think the culprit is using components/instances instead of using groups. Thanks again.
