material - file size problem

[OndraZ]

Hi,
sometimes we experience, that material size increase significantly (up to 10 MB), even if we don't use embedded textures. It happens with materials created in older versions (I don't recall when this issue started). When I edit some of these materials - unload and reload (same!) textures, everything is ok (file size is about 30 kB). This bug (I suppose it is a bug) complicates our work because it significantly increases dwg size and we work with dozens of files (as xref) via ethernet, so everything slows down...example sended via upload

This material has embedded textures already-- and the link name stored with the material isn't valid.  The global setting for embedded textures doesn't prevent loading materials w/ embeds.  It does prevent the creation of new ones unless you specifically override it.  To fix this particular problem:

 

1. Open the material in the external nXt Material Editor.
2. Click on the Texture Maps tab.
3. For each texture:
   1. click on the image on the Main Tab and load the appropriate bitmap
   2. right click on the texture in the list and make sure Linked is selected (don't remember if the nXt Editor respects the no embed registry setting.)
4. When you save the material, the file size should be about 23K instead of 6900K.

Thanks for reply. The path stored there works in our office. What I didn't know was that there is an option to have Linked an embedded textures

BTW what does this option mean? If are textures embedded, they are somehow baked into material file...so what for is there a link? What does it do?

[Roy Hirshkowitz]

If the link is present and more recent it will be used.  Otherwise the embedded copy is used.  The embed gets updated when you save.

Thanks for explanation
