[Possible Bug] "The Following Render Appearance Images Are Missing"

[pushenergy]

Hello,

Recently I've been working on a project which requires me to produce a fair amount of custom materials, while doing this I believe I have uncovered a possible bug in the software and was interested to learn if anyone else has encountered anything like this, has any solutions or any additional information on the subject.

It first started when a material I produced was in a project render. When attempting to render a project the following error was prompted (Revit Error Picture 1) "The Following Render Appearance Images Are Missing". At first, I thought the issue was caused by the "Additional Render Appearance Path" (Found in File>Options>Rending) being wrong, changed it, still an error. Edit the path in the .ini file, error.

After doing the normal troubleshooting Revit stuff I did a last-ditch fix and went into the materials causing the issue and reapplied the texture/jpg Images, It worked... I couldn't figure out why it worked by I didn't worry about it to much.

The next day after saving, closing and reopening the project I go to render the same project again and I get the same error, "The Following Render Appearance Images Are Missing", even the same materials as before. I repeated the same process as last time and it fixed it again. I couldn't work out why until I looked a little closer at the Image name in the material appearance menu. (Revit Error Picture 2) When exiting and saving the project the file path to the image reverts to lower case. I did some reading and it turns out in my situation this can be an issue, there would not be an issue if the images were stored locally, however, they are stored on a server. "Apparently" the way certain servers are set up case sensitivity of the file path does matter and the server my images are stored are conflicting with the case insensitivity of Revit. Anyway, that's what I believed was going on... I tested my theory by changing the name of one of the material images to all lowercase and after saving, closing, reopening and rendering I no longer got the error on that material image.

What do you think? is it just coincidence? Does anyone know another way around this?

Thanks in advance,

Jack

Hi @pushenergy

Its been a while and I'm checking back on this issue.

Are you rendering on the cloud? See related article HERE

Also, can you confirm if you have the latest updates installed for your Revit version?

Looking forward to your reply update.
