VfSU Materials Won't Purge From SKP Files [SOLVED]

[Jackson_cg]

Recently run into a very frustrating recurrent bug. Working as normal in SU I deleted a load of geometry and purged the file- all unused materials, components, etc disappeared as you'd expect, including from VfSU's Material Editor. However, after closing and reopening the skp file all the materials reappear, both in the SU Material Editor and the VfSU Material Editor.

I've seen this behavior in 3 skp/VfSU files so far and not only is it reproducable, it appears to be almost impossible to fix at this end. Only workaround I've found is to save out the visopt of the affected file and vismats for all the materials, open a fresh skp file, copypaste all geometry into the new file, load the saved visopt and import the saved vismats. This really isn't even a viable workaround as a) it's a huge amount of work and b) the next time you purge it's the same problem all over again.

I can email affected models to ASGvis if necessary.

Isn't this related to the same issue where material changes isn't saved unless you open up the Options window?

DOH!

LOL, talk about the solution to a problem staring me right in the face! Just did the open options/close options trick, saved, closed and reopened and voila, a nice clean skp/VfSU file! Thanks Thom- messy files really bring out the obsessive complulsive in me!

Hehe. I got the Purge function mapped to Ctrl+D. I find my hand hitting that combo automatically.

LOL, sometimes I think a good dose of OCD is actually beneficial for working with visualisation.

Still think it's incredible that the 3D Warehouse doesn't automatically purge uploaded skp files, seems such an obvious and simple feature to implement. It's amazing how even many experienced modellers are pretty sloppy with purging skp files.

meh! I feel I sometimes do nothing but moan Purge Purge Purge to the rest of the people in my office. First thing I sdo when I take over a projet is purge and see the file size drop tofolds.

Fortunately we have a FormFont account which got clean purged, to scale, models with no extra layers. The Google Warehouse gives me the twitches. So you can guess what I feel about SU7's 'feature' of linking the component library to the Warehouse.... *twitch*

Uuugh, don't get me started on SU7's Components Browser, I knew it was going to be unpopular as soon as I saw it and true enough, pretty much everyone hates it. Thank God that after a little while SU7 remembers that only the components on my harddrive are my "Favourites" so they're actually really easy to navigate to now.

I have never and will never insert a component directly from 3DWH into one of my skp files and I'd be amazed if any experienced SU user would do so. Contrary to what some pro SU users say, I do think 3DWH is actually a very useful resource, but I always open 3DWH files individually, purge, then check for reversed normals, unnecessary components or parts that should be components and extraneous geometry. Worst thing is finding a seemingly well modelled file and then discovering every circle is the default 24 sides so big stuff is faceted and small stuff (especially if the "follow me tool has been applied) is ridiculously high-poly. I wish there was a purge button for that!

Hi Jackson,

I'm having the same problem with colleagues using 3D warehouse and having materials retained by Vray in the SU files. I've tried the opening and closing vray options 'trick' but its doesn;t work, please can you describe exactly how you solved it?

Thanks

Are you using SU's purge command?

Window>Model Info>Statistics>Purge Unused

You could try the VfSU Purge as well. Some times there can be VfSU materials lingering.
