    Post Materials Losing the image file references

    Hi All,

    I'm getting a frustrating issue where a bunch of our materials are losing there image file paths. This started in Revit 2016 and is still happening in Revit 2017. After putting up with reassigning the file paths in 2016 I rebuilt the company template from scratch for 2017 then imported our materials and re-pathed the image files and all was good. But now I'm starting to get the same issue again. Its a real pain when it happens to downloaded families of which you don't not have the image file to reassign. Any ideas on what is causing this or how to prevent it? I don't see it as a common issue when searching google.

    Sometimes when I click the link to the image it opens the exact location of the material image and I just click and its reassigned so it hasn't even lost the file path its just unlinked itself somehow.

    Regards,
    Bryce

    Did you add the network paths to Additional Render Appearance Paths under Options?

    Darn, I didn't know that existed. So I presume the if I link the folders I have image paths directed at they will stay saved?

    Any idea where families you have downloaded store the texture files or are they embedded in the family file and if the link is lost you cannot get the image back?

    Thanks.

    Families don't store them at all, you need to download the image files and repath them.

    So... I am having this issue right now and was wondering if anyone has found a less time consuming solution than repathing all the materials.

    As long as you have a render path set and the material map is there the material will find it. Now exporting to various VR solutions doesn't always find it. So just get all your maps into a folder and add that folder location to the render paths under the big R settings.

    Tried replying to this but it hasn't popped up so sorry if my response comes up twice later.

    I solved my issue and the render path didn't have anything to do with it for me. I had recently uninstalled a bunch of Autodesk programs from 2013 - 2015 when installing 2017 to clear up some space on my SSD.

    I have since discovered that there are some key things to keep. I uninstalled my Revit Libraries from 2013-2015 thinking I'm only in 2016/17 now. The texture folder is shared between versions so I uninstalled the whole lot located here: C:\Program Files (x86)\Common Files\Autodesk Shared\Materials\Textures. Even though I had most image files on our company server there must have been some pathing info stored there as these all stopped working.

    To resolve I restored my library off a work colleagues PC. Everything works fine and I have not added and file paths to my render path settings.This may help you if you have done what I had.

    So these were not custom material maps but the OOTB shared ones. Yes this has happened to me to.

    i know that this thread is old but this is frustrating me. Can someone advise me if you need to add the specific folder where the texture is located or you can can add a parent folder and it will search the sub-directories? I have tried doing this and it is not finding the files. It only finds them when I add the specific folder that contains them. This solution is completely impractical as it means I would need to add every texture from families I download into one giant texture folder with no sub-folders.

    Can anyone please guide me as to what I am doing incorrectly?

    You need to path to specific folders. Subfolders won't be searched.

    As textures are separate files from revit families, are you saying you are receiving textures with your downloaded families? If so, subfolders or not, you're filing and repathing the textures back to the materials anyway....unless you store everything in your downloads folder?

    Unless its generic defaults (glass, aluminium, *maaayyybe* fabric etc) I don't bother assigning materials in families, I assign them to my families in the project. And the family geometries that are assigned default materials will be named to match the default in the project and be overridden anyway, or at least conform to standard naming format.

    As with downloaded families in general, materials found in them are usually junk as well. Build yourself a decent materials library and you won't need the junk. I really don't much rendering but enscape is quite popular in our office and I rarely hear complaints about dud materials or missing textures.
