Convert legacy materials tool

[Kevin Lockwood]

Is this tool working?

I just tried it on several legacy libraries with no success. The rare occasion when I think it did work, it looks like it skips bump maps. Also get this error every time

[Roy Hirshkowitz]

Clearly a bug.  Appears to be working here-- I'll pass it on to Renderplus.

I get the error in the R20 64 bit  version, AutoCAD 2015.
I'll see if I can figure out what the cause is.

Still works in the R19, AutoCAD 2013, version.

I posted a new version with a fix for the error being thrown by the Legacy Material Converter in AutoCAD 2015, version 0348-OA08.

If you are still having trouble with bump maps being skipped, I will need to get a sample .mlib file from you and some steps on what to look for.

It's working fine now. Thanks!

AR4 had a method of selecting images (multiple), right click and "convert to material", all from explorer, stand alone from AutoCad. Any chance of bringing that back? Maybe a set of nXt tools (materials, convert to HDRI...)

Stop!

When it converts the old material mlib it deletes the original files used (jpg/png...)

Its taken several directories of my textures before I found this.

I don't suppose you have a converter to pull embedded files out? :-/

[Roy Hirshkowitz]

The coverter should not delete anything.  All original material libs and maps are only read, never written or deleted.  The maps should still be in their original locations. This is a major bug if it's actually happening.

The converted materials probably do have embedded maps, though. There's no official, supported, way to extract these.

I didn't "test" this too much, but the one I "saw" happen was a series of 5 milbs and its material maps in a single folder. I only caught this because I had the folder with the materials and mlib open and watched the file count drop from 152 files to 119 after running 2 mlibs.

Another folder had a set of converted files, but all the .ARmaterials where blank white. This is a set I ran twice. Second time, the maps were gone.

I hate to say it, but it did work fine on a couple other libraries.

[Roy Hirshkowitz]

It may be writing some temporary files-- I can check the code-- but deleting input stuff doesn't make any sense and it's very unlikely that it's something I did.  Usually those files are opened in a way that doesn't permit deleting.  Nothing's impossible, though.

The converter has never been perfect.  For example, tga's are not used and must be converted to a different format.  I can try out any libs that you're having trouble with.  I will need the map files as well.

I tested it again at work. Used the same directory and mlib and the same thing happened. Here's a shot of the files disappearing...

I have the directory zipped up. files/folders/mlibs. 7.8mb

where do I send it?

[Kevin Lockwood]

I also searched for missing files. They weren't moved. Search found nothing but my backup zip.

That's not good.  Try here:
