WISH: Rhino not to store texture of inserted files in material

Rhino
1

Hi guys, @pascal @fraguada
I have a light file with heavy textured files referenced in (inserted) and I see that this bloats the main Rhino file a lot. So I presume it is because Rhino stores all materials in the file. Also the referenced files’ materials.

If I delete all the referenced files and purge and save, it goes from 101 MB to 60MB.

And I see that if I toggle of SavePluginData then it jumps down to 30MB. (I have LandsDesign installed, but I don’t ‘use’ it in the file. If I open the saved file that no longer has the plugin data and saves again with plugindata it jumps back up to 60MB.

Any idea what causes all this?

To make it a bit stranger… If I turn off loading of LandsDesign and restarts Rhino, and opens the saved file without plugin data and saves that again with plugindata it jumps back up to 60MB… so it appears this is not’s Lands fault.

I just tried the same regarding the Datasmith plugin: disabled it, restarted saved with out plugindata, reopened the file and saved with plugindata.

Is there a way to see the plugindata that is in the file? And also delete it permanently?

5

See the actual data, no, but running Audit3dmFile on a file will show you how much data (in bytes) is associated with each plugin.

Thanks! I can confirm that it is the linked in files textures that are saved into the Rhino file.
So I wish for this to not happen.

That doesn’t seem like much though… certainly not enough to explain 30-60 Mb of difference.

85 texture mappings, 37849 bytes = 38 Kb
101 materials with 6 plug-in data items, 54182 bytes = 54 Kb

Maybe something else? Check the plug-ins section (near the bottom IIRC)?

8

Haha… good point! I read those as Kb’s…

So Tibidabo eats 28 MB and the textures eats 45 MB

@fraguada
I just checked and Tibidabo has a purge (tbPurge) and if I run that on a new file it finds 16 objects:

Command: _New
Command: tbPurge
16 unused objects found.
Are your sure you want to delete all those objects? ( Yes No List ): y

Any idea what those are, and is it safe to purge it?
I just purged the file I am talking about, that removed 125 objects, and saved afterwards (a backup), but that only removed 0.1 MB.

Yep, looks like the RDK is using 46 Mb and Tibidabo (LandsDesign/VisualARQ) is using 28 Mb.
