Hi daveyjones26, Here is a script that might help, there are two functions vrayTraceSetsAdd() and vrayTraceSetsRemove() that operate on the current selection of objects, so they could be assigned to custom button or menuitem. In all cases the last object is considered target, so You should have at …

Many thanks Alexander, Just having trouble using this script (im not to good at scripting). When i run this script it flags a error in max lister? how can i get the to work? buy cutting out the vrayTraceSetsAdd() and vrayTraceSetsRemove() and creating two scripts to lunch? Would be possible the s…

Hi, Can you paste the output from the listener? It works fine here with V-Ray 3.0 and 3dsmax 9 and 2014. Yes I think we can make another set of functions to work with the lights exclude lists. Best regards, Alexander

hi Alexander, when just selecting target object on its own, this is what max listener outputs: vrayTraceSetsAddNodes() vrayTraceSetsRemoveNodes() vrayTraceSetsAdd() vrayTraceSetsRemove() The reflection/refraction exclude list is empty? Also if i select a bunch of objects and select target obj…

Hi, As far as I can guess that is the result from evaluating the script. You have to evaluate it only once, or you can put it in the 3ds Max startup scripts folder (i.e. C:\Program Files\Autodesk\3ds Max 2014\scripts\Startup). Then you have to call the function to do the job, when you have the obje…

Hi, I am new to Vray and to this forum and I am trying to access the exclude from reflection list, aka trace list in maxscript. I can’t download the link in this post probably coz I never posted. Is there a documentation on Vray and maxscript?

General documentation about V-Ray and MaxScript is here: [image] Chaos Docs For access to the forum, please email support@chaosgroup.com Best regards, Vlado

Thank you, I didn’t spot the trace set at first glance… How do you show the interface of .reflect_exclude, it does not show with showproperties $… Also, how do you turn exclude list into include list? I want to do a simple script to edit two lists and connect them on include and exclude, a bit li…

Ok you can do like that ExcludeList = vrayGetTraceSets $ show ExcludeList it returns .reflect_exclude : node array .refract_exclude : node array false why false??? is it the exclude/Include switch?? How to change it?? Thank you.

Hi, the trace sets are not exposed to MaxScript with the ability to be used as include type lists, which we will have to fix. Currently it is possible to change the type of the list only through the UI dialog. Best regards, Alexander
