I try to describe my problem in simple language.
The scenes I create are all complex indoor scenes, and each file will contain more than ten scenes (under normal circumstances, saving them will take several hundred MB).
Different projects will import pre made keyshot files from each other.
After frequent file imports, two problems arise: slow file saving and large file size after saving.
For example, when I delete all objects in a normal scene and save them, it’s probably less than 100KB.
But after deleting all the objects in the problematic scene, the empty scene will still have several hundred meters.
Open a new scene and import items from the problematic scene. The new scene will have the same problem as the old scene.
This problem is very troubling for me, causing me to be afraid to use the files from previous projects, which greatly delays the progress of work. I have also encountered some people who have the same problem as me, but do not know how to solve it
I uploaded an empty scene where you can see that there are no objects, but there is 140MB. I hope everyone can help solve this problem. Thank you
I think @joey.lopez had this issue as well but not sure if he found a way around it or got it solved. Only topic I found now was this one but I know there was another as well:
Here’s the only thing we could get to work: Go back to the original CAD - wether from a plugin via a CAD app or a native cad file, and re-apply CMF. There are some workarounds to help with all of this RE-work, especially using your Library as an intermediary between your old and new file as you rebuild your work, I have a list in the original thread, but this is an updated list based on advancements made since:
Look into material templates (google, there’s luxion videos on youtube) - assigns a material from the scene to a named cad object if the names are re-used, (requires not editing the hierarchy of the model nor any of its names) comes in extremely handy and potentially can save all work you’ve done, if not most of it. very subjective though depending upon how the file was originally imported, also buggy.
save materials to your library, allowing you to re-use them in other files easily (there’s a setting in preferences btw that toggles on or off duplicating the material or reusing it when you apply it to the model from the library)
save environments to your library, same
Avoid un-used displacements in multi-materials (this seems to be a very very coincidental if not triggering event for these file bloats, but I’m not 100% sure) Better to bake out any displacement as an additional model set than use them as they also tend to cause file slowdowns and errors during saving/opening when attached to multi-materials. Again not sure if this is a bug or coincidence.
Save iterative saves yourself, e.g. MyProject_V02.bip, save after each file related step when building your CMF - after every import.
Use model sets, multi-materials, and configurator wizard to reduce redundancy of models in the file, anything common among studios should be a model set with the non-common elements in their own.
Do not save models to your library from these problematic files, it is the same as saving/importing a .BIP.
Do not attempt to import any elements from a problematic .BIP, nothing, and I mean NOTHING will work, not even a single camera, it will bloat the file same as if you imported every model and studio.
