I keep having this problem where a vray sun just keeps appearing in my scene, I’ll delete it and magically it will reappear later. It’s always in the same spot and it’s always named the same (vraySun02). I’m not merging anything into the scene when this happens, the last time it did this I was just chaining material ID’s. This only started happening in the last few days, I haven’t changed anything on my system, I’m running Max 2011 SP1 & Vray 2.00.02.
Is there a VRaySky texture that uses that sun light somewhere in your scene?
Best regards,

I live in Ireland, I don’t get this problem.
ha haaa same in London dude 
i find on importing materials from other scenes it drags the sun in.
I’ve had this issue too. I’m trying to track it down to see if I can recreate it, but I get 3 additional vray suns that just appear out of nowhere…all 3 right on top of each other. It happens quite a bit, but I can’t figure out when it’s happening. For a while it seemed like it would happen when I applied the max ColorCorrection to a shader, but it doesn’t always happen with that.
I have a single Vray Sun with physical camera and a VraySky in the environment map slot if that’s what your talking about.
Ok; is the VRaySky texture connected to a light?
Best regards,
Vlado
Yes it is.
Ok then; try disconnecting it so that it can find the sun light by itself, and see if the issue continues. Also does saving and re-opening the scene fix the issue?

I don’t think so because it has happened on the same scene more than once at different times on different days. I wish I could tell you that doing a certain thing caused this to happen but I don’t know that for sure. I’ll do what you suggest and see if it happens again. Thanks.
It’s just happened again and I was doing the same thing I was last time, selecting materials from an object and applying new materials to it, this doesen’t happen due to merging.
Ok then. If you can get us a scene and some instructions how to reproduce it to vray@chaosgroup.com, it will be useful to troubleshoot the problem.

I don’t really know what’s causing it yet, I’ll see if I can reproduce it.
Vlado I’m absolutely sure this has something to do with the material editor, every time it has happened I’ve had it open. Most usually I am picking a material from an object using the “get material” button and selecting it from the scene materials. Funny thing is it doesen’t happen every time, durring an 8 hour day it may only happen once or twice at most.
OK I was finally able to reproduce it following these steps:
-Opened Max
-Imported a model
-Opened material editor
-Selected get materials
-Under scene Materials selected desired material
This is when the Vray Sun 2 appears, this only appears to happen once per Max session or at least I can only get it to reliably happen the first time I import an object and select it’s materials. When I try and make it happen after the first time it won’t work and it behaves as it should, I can send you the scene if you wish.
Devin/Vlado, this recreates it for me too, except I get 3 Vray suns right on top of each other. This happens in max 2010 and 2011, vray 1.5 and 2.0.
ok im getting the same problem.. have a simple scene with a vray sun and sky (not manually linked) and a couple of objects including a vray plane.
i add a map to my vray material (first time was edges tex, now distance tex) and hit render.. blam its super bright.. i look and i have another sun with the same name as the first in the scene. delete the extra sun and carry on.. add another map, and boom, another sun with same name is created.. very strange. i didnt do any importing or anything.. simple as can be.
max 2011, vray 2.0
tried re-opening max and the file, still happening.
Today when I simply selected an object that already had a vray material assigned and assigned a new one to it the sun magically appeared. At the time I was using the render region function in the VFB and I changed it size before I hit render but I don’t think that had anything to do with the sun creation. It always seems to appear when I’m manipulating materials in some way, but it doesen’t happen all the time.
Been happening to me lately too - also with importing models. Thought I was just being an idiot This scene also had a sun/vray sky at one point, but the sun is deleted. Vray sky is still in the scene and is set to “specify sun node” because the sun was originally used to set the look of the sky map.
