I am having an issue with Vray and it is that when I open my Rhino file and start up Vray, all the materials in my rendering are black.
When I saved it everything was working fine and I made sure that save plugin data and save textures was checked (and everything else unchecked).
Maybe it’s relevant to explain that I am using my university’s computer to do the rendering. This means I can’t save my file on the computer, so what I do is put it in my iCloud and then download it again the next day to continue working. This has never caused an issue except now that I am using Vray.
Any ideas on how to fix this issue?
I have attached pictures so you can take a look.
I would make sure that you find these files and store them in your cloud as well. And then “replace” them when you are trying to render with these materials located somewhere else.

I need the Citrix software because this is how I access my university’s computers remotely. So uninstalling isn’t really an option… what else could I do?
I’ve made sure to check that box when saving my file, but it doesn’t seem to work when you save and download from a cloud service (I’ve tried with iCloud and Box)
Here’s what we know:
The culprit is epclient64.dll included with Citrix ICA Client, a remote desktop tool.
We have heard you can make apps work with this if you do not enable the keylogger and screenshot feature.
Rhino may fail to launch on some systems with Citrix Workspace 22.6 installed. We have heard it works better with 22.2 and 22.
Hello, Sebastian,
It looks like the black appearance of your rendered model is due to failure to locate texture files (when invalid texture is loaded or its file is not found, its output is black).
To amend this, simply open the Rhino menu V-Ray > File Path Manager and ‘repath’ each missing image file.
To avoid this in the future, please use the V-Ray > Pack Project action.
It creates an archive file of both your 3dm project file and all asset files V-Ray uses in that project. This way both the 3dm and all of its auxiliary files can be safely moved between computers. As long as you keep all texture files in the same folder as the 3dm, V-Ray will auto-resolve their paths.
It is important to note that V-Ray materials have some extra parameters in comparison with Rhino ones. Therefore, when saving a 3dm project with the ‘Save Textures’ option enabled not all image files used by V-Ray are guaranteed to be included.
Sorry for the late reply, I didn’t have access to internet for a couple days. I do not understand what you are suggesting that I should do…
I’ve never had any problems with Rhino or any other software using Citrix other than this one specific problem of always having my textures/materials missing when I open the file again. I don’t understand why Citrix would be the problem if I am saving my file to Box and downloading it again to continue working on it.
This got me really excited at first because it seems like the solution. So I gave it a try: I saved the Rhino file, I used the Pack Project action for Vray, and I uploaded it all in the same folder to Box.
I downloaded it again (as a zip), but when I tried to extract the files from the location where I supposedly saved my work, I got an error message saying the compressed folder is empty.
When I opened the Rhino file, I got an error message due to Orphaned Materials, I hit Keep, and then I got right back to where I started with the problem of the missing image files.
What should I do? I attached pictures so you can see.
Hi, we use LZMA as compressing algorithm. That is native to 7z archiver. However most Windows systems do support xLZMA, which is a variant and those system typically work well with LZMA as well. Apparently that is not the case for your system for some reason. So please:
Verify the .zip file is not 0KB but somethin reasonable for the file size of your model
Try to use 7z application for extracting the archive contents.
if none of the above works most probably the archive is corrupted, and in this case you should contact the support team for further investigation
not sure in what ways this may be affecting things, but I notice that you have opened the 3dm file in read-only mode, due to trying to open it while it is still inside the zip
I would try unzipping the zip first, to eliminate unnecessary variables from the situation
windows allows navigating into a zip and giving the impression of working with files inside, apparently to try and make things simpler for people, but I’d say it just makes them more complicated, especially when you are dealing with external referenced files, are forced to work with the file in read-only mode, and so forth
In case anyone needs this (including my future self), this is how you do it:
When you begin importing materials from Chaos Cosmos to your Asset Editor, two folders will be created somewhere in your files (in my case, Desktop) where the information for all your materials will be stored apparently: Lock and Packages; create a “master folder” where you save both the Lock and Packages folders; save the Rhino file to the master folder; save your Vray work by using the Pack Project action under the Vray menu to the master folder as well; upload to your cloud service; when you download it again it will be zipped. Right click on it, extract all. Delete the zipped folder, keep the extracted folder; you only need to open your Rhino file and it will be as you left it!
To continue working on your file without having to resave everything, just make sure that when you download/import new materials you select the location of the extracted folder. If you download materials from the internet, make sure you place everything (once extracted, if necessary) within the master folder.
