For some reason the Automatic Scene Preview doesn't work, even when it is set to "Auto Update", "High Priority", and "Preview quality>Fast". I have to keep clicking the bloody window for it to reflect any changes. The Preview window in the Material Editor doesn't update either, and again I have to click manually to reflect changes. I know this sounds lazy but it gets awkward when you have multiple windows open in the Editor and always having to click the window to see any changes.

I checked in the Preferences, and the only relevant option I found was in "Display>High priority scene preview" which was already ticked.

Vue5Inf is fully updated at this time....I'm guessing one of their "fixes" - like always - made things worse. I've only had Vue5Inf for about two months, so maybe they changed the whole Preview thing since 4.

I've had this happen to me as well, JoeBlack...and it's not, to me anyways, new to this update. Rather...it's usually an indication that VUE (and my 'puter) are telling me that I've just about reached the limit sizewise of what I'm going to be able to do with that particular render...which in my case is just about every one I do...LOL! I realize that this doesn't solve your problem, but just wanted to let ya know that you are NOT alone there '-)!

Thanks, spider, though I should have mentioned it does it even in fresh scenes, and just a groundplane. I think I've found a possible reason, though: when Vue crashed once, it went to "Compatibility Mode" - according to a post on e-onsoftware, when it does this certain features like Automatic Preview are disabled. And in the Material Editor if you see a small exclamation mark in the window it means this too has been disabled. To fix this, go into Otions>Preferences and choose "Restore defaults". Preview options for scene and material should work again.

I've done that and some previews seem to work, but again the bloody scene preview needs to be clicked manually sigh. I guess I'm too used to Vue4.

Thanks for the hint. I'm struggling with the same problem, too, sometimes, but at times it gets even worse... even clicking on the scene preview manually will not update it :-( The material previews always worked this way (with the exclamation mark), but it seems that V5I is often awfully slow at updating them, automatically or manually. Maybe it's really got to do with resource problems, but it's nasty anyway.

Make sure "High Priority Scene Preview" is checked in your Options menu and "Background Draw" is cranked up to 75% or more.

Thanks, the first is, but I'll surely try the secondd.
