Hi everybody!
My problem: I’ve sculpted a low-poly treasure chest into a high-poly version, then tried to export it as a single OBJ. The result is a huge 3.4GB file for an ~18mil polys tool composed of 11 subtools.
By exporting each subtool as a separate OBJ file, though, the total size is just 2GB. Why such a discrepancy?!
Some more details: this is a project for a game design course started with a low-poly model we made in Maya, then imported it in ZBrush for high-poly detailing, and ultimately destined to get textured in Substance Painter.
Everything went pretty fine up to the high-poly sculpting, but when I tried to import the 3.4GB OBJ file into SP for geometry-based maps (normal, AO, glossiness…), SP crashed even before reaching 1%.
Just to be sure there wasn’t an issue with drivers and the likes, I’ve tried exporting/importing an OBJ file containing a single subtool, and SP worked it out pretty fine. Huzzah!
Now, I’ve already asked for help on SP’s forums, but in the meanwhile I’ll have to make it work in some way, thus I’ve tried exporting every subtool as a separate OBJ file, so that I’ll be able to produce the maps and eventually blend them into single files in Photoshop (easy, but time-consuming).
By doing so I’ve noticed something that baffles me: the amount of space taken by the separate OBJ files doesn’t add up to the size of the file containing the whole tool. It’s not even close! Bizarre!!
Just to be sure it wasn’t a matter of intersections, I’ve tried putting some distance between subtools and re-export them as a single OBJ file, but the result is the same.
So now I’m wondering whether there’s something I overlooked when I exported the whole tool in one file.
Any option I might’ve forgotten to tick/untick?
To export the whole tool in one file I used the “3D Print Hub” plugin, while I exported the single subtools with the embedded function in the “Tool” palette.
Maybe the plugin’s method throws in some extra, unwanted informations?
Help, please. =0
