Crash on entering the material room was a common bug report during beta. Two weeks ago, every single person in beta test who ever saw that happen said it never happens anymore.

Unfortunately, there must be still more situations and configurations that were not discovered. Such is the nature of Windows and the 8 million possible combinations of hardware and software we all have.

The material room is a fair bit of complex GUI work, and though it sure looks about the same, it was completely rewritten from scratch. Just getting it back to the exact same as it was is a lot of work. The groundwork is now set for material room innovation. The old implementation was a dead end. Small consolation, I know, but that was the point, in case you're wondering.

If you have not done so, please report this crashing to SM customer support. More data means more likely to be fixed, and sooner, perhaps even a patch release before SR1.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
