VRaySun Added to Scene Mysteriously

[Joelaff]

I had been seeing this weird phenomenon for a while, then it went away for months... then it came back, and I figured out what causes it.

What phenomenon? LIiterally random VRaySun lights being added to scenes... to most scenes in fact.

It turns out if you open a .max file in the Slate Material Editor as if it is a Material Library, and that .max file contains a VRaySun then there is a high likelihood that at some point that VRaySun will get added to your scene. In my case they were always added disabled/hidden, but that may have just been the state of the VRaySun in the scene that I had loaded into the Slate Material Editor as a library. I have not nailed down what action cause the sun to get added (it may be saving and re-opening, or restarting Max with the scene file still loaded in the Slate Material Editor as though it is a matlib. (see pic with well-named materials).



If Chaos can reproduce this maybe they can prevent it from happening. It wouldn't surprise me if it had something to do with using the Sun with the VRaySky environment map.

This has been happening to me for yeeeeears. Pretty sure it's a max thing and not a vray thing...

Does it only happen if a scene is loaded as a matlib as I describe? Or does it happen otherwise? I only seem to see it in the case described, and I think it is only every VRaySuns. But maybe it was other lights too. I think I have seen it off and on for almost a decade as well.

Scene as a matlib was what I strongly suspected all along but I never tested it thoroughly. I only ever noticed a detached vraysun appearing; never any other lights.

Yeah same here (haven't seen it happen with just a matlib, but when loading it as Max file like you said), very annoying. Also when loading in material with VrayDistanceTex maps, it loads in all the geometry that is linked to that distance tex map.
