Maya subdivision displacement - how to ?

[Dariusz Makowski (Dadal)]

Heya

Just trying to figure it out... How do I get it to work ?

I found this script, but I'm interested in learning how to do it by hand...

Thanks, bye.

I rewrote that script a bit, I commented out some extra commands for you to remove or set the specific options. It should work on all poly meshes which are in current selection, but I also left an option to put all meshes in scene you will need to replace the $relatives with $Sel2

//will work on selected
string $Sel1[] = `ls -sl`;
string $relatives[] = `listRelatives -shapes $Sel1`;
//will work on all
//string $Sel2[] = `ls -type "mesh"` ;


for ($i=0;$i < size($relatives);$i++)

{

vrayAddAttr $relatives[$i] vraySubdivEnable;
vrayAddAttr $relatives[$i] vraySubdivUVsAtBorders;
vrayAddAttr $relatives[$i] vraySubdivUVs;

//setAttr ($relatives[$i] + ".vraySubdivEnable")1;
//setAttr ($relatives[$i] + ".vraySubdivUVsAtBorders")1;
//setAttr ($relatives[$i] + ".vraySubdivUVs")1;

//vrayDeleteAttr $relatives[$i] vraySubdivEnable;
//vrayDeleteAttr $relatives[$i] vraySubdivUVsAtBorders;
//vrayDeleteAttr $relatives[$i] vraySubdivUVs;

};

Btw I would suggest to create a control node to connect to multiple objects so you can control their enable/subdiv option with one click rather then a script later, it can also be layer overridable...which can be handy.

interesting, thanks !

Still, I know how to use this subdiv in max, what about maya? Where I add it and so on ? :s

Vray for maya could really use some tutorials, or am I missing some obvious source?

Thanks, bye.

For a general description of the V-Ray extra attributes, look here: http://www.spot3d.com/vray/help/maya...xtr_atrrib.htm

For the subdivision attributes specifically, look here: http://www.spot3d.com/vray/help/maya...rib.htm#Subdiv

I think this area (with custom attributes) could be included into vray object properties (or similar node) otherwise without script it becomes somewhat difficult to manage multiple objects.

[vlado]

In fact, you can already add the subdivision attributes to the vrayDisplacement node. In that case, it will work as though you have added subdivision attributes to all nodes connected to the vrayDisplacement node.

Heya

Got it to work, its quite well how the node system works. I link all of my meshes to 1 displacement node and all works well so far... gotta run some tests tho.

In any case... How do I decide what displacement I'm using if I want to use displacement with textures? Like 2d/3d one etc etc?

Thanks, bye.

[Morbid Angel]

its another set of vray attributes where you can select which displacement it is.

[Dariusz Makowski (Dadal)]

Yea I saw that there is 3 set of attributed to pick from once I add displacement node to object. Ehh this maya is such a pain in the ass to manage, even with vray. I gotta sit down and go over papers, it aint as straight forward as max one heh.

Thanks, ciao.

I don't want to start a maya/max debate, but coming from max I find maya to be a better overall software. You just need to get used to the logic and find your way around things. Some things are better then in max, some things aren't, you can't have it all...

[Dariusz Makowski (Dadal)]

Heya

Of course I dont mean that max is better than maya or anything like that. I just say that maya is a bit more difficult and vray is in a way following maya difficulty
