Good Morning all,
I’m trying to understand packing resources and linked files to work out why my file size is so big.
My file with resources and linked libraries packed is 546.8 MB
My file with resources and linked libraries unpacked is 37.3 MB with a texture folder of 408 MB.
So this leaves 100 MB not accounted for? any ideas?
I know I need to reduce my texture map sizes as some are 49MB!!
What would be a good average size to go for, for mid range view?
Cheers

That’s weird, could be that some images have the same name and get overridden.
The file size on disk isn’t really relevant. Say your texture are saved in .tiff , you can save some disk space by saving them in .png . Then the file will take less disk space because some compression happen (similar to .zip, .rar …) . The file will take less space on disk at the cost of a slower reading/writing.
You can also use .jpg that will compress the file destructively , mean that some data will be loss but image will take even less space on disk.
Why do you feel the need to reduce file size ? Is it for better performances in blender or you’re running out of disk space ?
Do you talk about the image format in pixel ?
Can’t give you a good size, the important is how much of that texture show in the render.
Let say a 4096x4096 texture end up in a small area in the render like 256x256, then this texture can be 512x512 and you won’t benefit an higher size of image.
But a 4096x4096 image may not be enough if you are quite zoomed on it.
Once again, what is the reason you want to do that ?, what’s the problem you’re trying to solve ?, or what problem these 408Mb of texture is causing ?
Thank you very much for your input.
The reason I want to save on file space is beause when I select my blend file to takes up to 15 mins to open.
Also Blender takes a long time opening up if this file is in the recent files window when starting Blender.
I recently installed Blender 3.2 and all worked fine until I opened this file and it was listed in the recent files, meaning if I try to open Blender and just the default scene file, it still takes along to time to open.
The reason I have been packing and unpacking, was just to get everything in the same directory.
I was thinking if blender has to load up 408mg of textures is this reason for the slow down?
I’m stumped.
I also tried resaving the file with a different title and opening a fresh file and appending the required content from the original.
Stumped?
That’s weird !
Have you tried to get rid of the history ? in blender to make sure that’s the issue ?
If the images are unpacked they shouldn’t be loaded until they are needed , like when you trigger a render or a preview of the image.
Something that can slowdown loading of a file is when you have a lot of modifiers.
Say you have a cube with 10 subsurf level, once you open the file blender needs to compute that geometry , and because there is a lot of subdivision that can takes some time.
37Mb isn’t a lot for loading the file into RAM , so maybe the issue is elsewere.
check for high value of subd
or if you have large particles or physics system
also when you upload if it also has to render in material mode
it will take a long time to get the render
so may be save it in solid mode instead
should make it load way faster
and use material mode only when necessary
i had file with 600 MB and it takes a few seconds to upload
happy bl
OMG save in soild mode why the F did I not think of that!! 
I always set to solid mode before rendering, so why did I not see this.
Your a life saver, Thank you very much

depends what you smoke LOL
