i have a free model of human with map. model is 4 mb and map is 6 mb.
if I save with texture, why is file size 60mb and not 10mb?
anyone??
How big is it if you save without the textures?
4mb - so very small
Well, I’m going to hazard a guess here - You have a mesh - which is basically just a collection of points and a list of which points make which mesh face - plus the image itself stored in the file. Each one of those has a memory size and you could basically add them together to get the total.
But, you have also applied the image to the mesh as a texture. That means each mesh face gets a color (maybe the mesh vertices as well) and that will add a huge amount of information (size) to the mesh object. So I expect (suspect?) that it’s the texture being applied to the mesh which is contributing to the file size.
You could maybe run Audit3DM on the file and see what it tells you about the objects in the object table.
This is just a theory of course…
hello and thank you, for me this seems like a very simple question… i can understand if the file is 10mb.
here is the Audit3DM results:

This looks like V-Ray - 57Mb of data being used by the plug-in… I guess it’s the texture mapping info, but no idea really.
thank you
deactivated the Vray plug to see if that made any difference… no, just the same
so I tried this in version 6… In 6 there is a new flag when saving ‘save plugin data’ seems which I switch that OFF then the file size is back to very small… so must be some data in there that is linked to a plugin…
Yes, and that plug-in looks to be V-Ray. Deactivating the plug-in does not purge the data it has stored in the files, only saving without the plug-in data does.
and no option to do that in V5?? or have i missed a flag
-SaveAs (dash version) has the option on the command line in V5. It is indeed missing from the dialog version.
wow - worked!
never new about the Dash version of commands, does this apply to all commands in 5?
The dash version of a command bypasses a dialog box - if there is one - and all the options are shown as command line links. This is designed to make all commands macro-able. If there is no dialog for a command, the dash version runs like the regular command. However there are a few commands where running the dash version exposes some additional command line options.
Dash versions have been around since V2 or earlier.
