Material Path Lite

Material Path Lite

Win64, English

This add-in is aiming to help you to find and edit missing material bitmap file paths.

General Usage Instructions

Open add-in in project or family environment. It will list all materials which have bitmap file paths. Double click on the file path, it will bring up the opening file dialogue for you to choose a new file. After choosing, the column will be on green background, which means it is ready to be applied. Or you can have two separate clicks on the same file path, it will activate text editing in the cell. Hitting the "Apply" button will apply new paths to the material. Before hitting the "Apply" button, all file paths are the same in the project, which means you can hit the "Reload" button to reset all pre-edited paths if you are not satisfied.


You can open the material browser by double-clicking on the material name in the Material column. If the material browser is already open, double click on the material name in add-in's form again, it will put the material name in the material browser's search box which can help you to find the material quickly.


For relative paths created by using Autodesk® Revit® Option-Rendering-Additional render appearance paths, this add-in can test their validity. When you open this add-in, those paths may show in an invalid state, that is because those assets are not been updated by the user. They are just temporary paths during each Revit session, if you remove Additional render appearance paths in Option, it will show the real paths in assets. Most of the time, they are invalid. By using the ‘Test RenderPath’ function, this add-in can automatically detect the correct valid paths for those assets. If successful, they will show on white background, which means they are valid.  This add-in also provides an extra function for you to export or import your Additional render appearance paths by extracting data from Revit.ini or inserting data into it. It is very useful when you need to transfer your rendering settings to the new station. It’s located on the top strip menu named “RenderAppearancePaths”. 


You can delete material by just right click on Material's name in the Material column and choosing delete from the menu. Or you can use the “Delete Material” button to delete all checked materials. Please be noted, that deleting material doesn't mean the asset related to also deleted. If it is a shared asset, the missing path will still be in the project. It will show up after reloading. This add-in only loads a unique asset, which means if another material uses the same asset, it won't be loaded into the form. For the sake of editing speed, you would not like to edit the same asset more than once.  


There are Four settings in the Setting dropdown list.

  1. AONE Tab: let you choose to use our ribbon tab or just default Add-in ribbon tab. It will take effect on the next session of Revit. to include default Revit preset materials inside your project, which have not been modified by the user.
  2. Test Rendering Paths: Test invalid paths with Revit-Option-Rendering-Additional render paths before loading into Add-in. If successful, it will show those valid temporary paths instead.
  3. Include Default Material: include default Revit preset materials inside your project, which have not been modified by the user.
  4. File Search Speed: By default, it is set to Fast. But if your network environment is complex or your equipment is not fast enough, you might need to set it at Mid or Slow. Otherwise, it may give false information about the validation of the file path.


There are two extra functions in the RenderAppearancePaths dropdown list.

  1. Export from Revit: export Additional render appearance paths by extracting data from Revit.ini and saving it as separate *.ini file. The preset name would be “User name”+Revit version+RenderPaths.ini.
  2. Import into Revit: import Additional render appearance paths from your custom *.ini into Revit.ini. It will take effect in the next session of Revit. It will also back up the original Revit.ini as Revit_Backup.ini in the same directory.


Tips: For editing large projects in a complex network environment in 2020 and the prior version, it would be better to finish editing all missing paths before hitting the apply button. Because it will take a longer time to start processing the first material. Sometimes, take more than 2 to 5 mins, it depends on how complex the network environment your computer is in, especially when the original paths start with //192.168... If it is hanging there, it's not dead, just needs more time and patience. But after that, the rest of the materials may be processed more smoothly.  Check Purge Unused AppearanceAssets will greatly improve material browser and this app performance (Default is checked).
