🧵 project is too big for blender
Anonymous at Fri, 15 Dec 2023 00:08:05 UTC No. 967198
I got a request from a friend that does 3d printing and he wanted to print a small tiny replica of the church he goes at, he got permission from his church to do this and they even got him an STL and OBJ file of the entire building that they had because they were planning on renovating. He takes a look at it on his slicer and it comes with errors out of the wazoo, the model needs to be cleaned. We're talking few holes in the parking lot, bottom side not being fully closed so the splicer won't properly set a base, and lots of geometry on the inside because it is apparently an exact replica of the building inside and out. He didn't know how to tackle this so he sent the files to clean them up. On the surface this should be an easy fix, I already have thought several ways to get rid of the inside geometry and the holes in the model will boil down to just patch them up, problem lies in that the OBJ file for this project is 3 GB and blender just freezes up after like a few minutes of working on the project. inb4 "just get a better PC" my PC isnt the issue because I have a 4060 ti, a ryzen 9 5900X, and 32 GB of RAM. I can keep using my PC just fine, it's just blender that just stops working whenever I try to work on this model. And I know that given the size of this thing and how many faces and vertices it has (pic related) is probably overwhelming the software, is there a way to tackle this? I'm open to at least try on other modeling software to at least hollow out the inside and least chop down the size of the file to a more workable state for blender, any ideas?

I could start the 14 day trial that they have, although I will need an hour or two to learn the UI. hopefully this will help

Yes, I agree, Zbrush can handle that ammount of geo without any problem.

Dumb Blender advice and not understanding how things work. Even if you lower the polygons, Blender wont accept it and your going to be left with inaccurate model.
The only real answer is to abandon Blender and use CAD software. If you say it’s a scale of the building then the STL should have the real 1 billion polygons model that should not be a complete mess.
There’s nothing Blender can do, it’s not a CAD software nor was it built for real life models.

literally. 12 million verts isn't even approaching "big" for zbrush.
Just take it into zbrush, hit it with decimation master then take it back into blender.

No one likes CAD autists because you all act like this. Under-socialised STEM wannabe retards.

This is why no one likes you blantets, CAD is design for such events and it's the only way for 1:1 of the model. You just mad that Blender can't do such a simple thing or handle 24 million polygons. Shame, this never happens in Autodesk.

I'm not mad, I'm a zfag and why would I get mad over software? I just use whatever software that does what I want. It's not personal lol.

blender and any other 3d software will be slow to load this file because OBJ is a text based format that's very inefficient to parse. A vertex can be expressed as 3 floating point values for a total of 12 bytes, while in obj, you need to write ascii representations of their coordinates, and these usually go to 7 significant digits per coordinate, so a single vertex can easily reach 40 bytes, then there's extra bloat to express how to construct each of the 24M triangles.
Though the crashes your experiencing are blenders fault, or your driver, as I don't think blender would have a problem with 12 million unshaded vertices.
I'd suggest first using a converter to a binary format that's a superset of OBJ, like GLTF in its binary form, GLB, and give it another try. The amount of data you have should fit in like 200MB.
