All of the materials were "Rhino custom". I wanted to check if there is anything to adjust to help resolve the obviously problematic render, I noticed that there were no materials in the vray asset editor window. resulted in freezing the program (waited more than an hour in some tries, but program was still "not responding" in task manager). After it finaly did open, it was impossible to handle - selecting any object, moving in any view. This has never happened to me on any file.Īfter a few more attempts of rendering (I did not save the file, the date still shows it was last saved on friday), I restarted the computer (it was not restaretd between friday and monday), after which the file started to take forever to open (20 - 30 minutes). Monday morning, when I first opened the file, it seemed fine, when clicking render the Vray VFB opened for a few seconds, the moment that the precalculations were over, the VFB and Rhino just dissapeared from screen (no error message, just closed). No problems whatsoever, one of the last actions on friday was a render. Worked on a file for a few weeks, last saved on friday. Yesterday, after using Vray for Rhino for a few months I encountered the same problem. I am asking for help because I waste a lot of time and money constantly restoring and re-creating materials in scenes. I do not know how to fix it and I can see that others also have a similar problem, not to mention the message "disconnected materials" appearing from time to time. The problems started with v-ray Next and are repeated in the latest version (earlier versions did not have this problem). You can have fun over and over again from time to time. I can play most of the stuff like this, but sometimes it only works until the next file I'm working on is opened. Recently, it is enough to restart the computer and all the materials from the file on which I work disappear in the V-ray table, when you hover over the model, the material appears as "custom", after converting them to v-ray material, they appear in the v-ray table back, but duplicated, sometimes they are correctly reproduced, sometimes they are black.

I create scenes from scratch using only v-ray and cosmos materials. Let me add that I have the latest version of V-ray and Rhino. For a long time I have had problems with materials that disappear from time to time, all in a similar way to others.
