How to apply a .Net method to 3dsMax

Submitted by sekopasa on Fri, 2012-09-21 00:45

IList propertyNames = TheJObject.Properties().Select(p => p.Name).ToList();

this is the code in .net i'm trying to use JSON library. Everything is fine but i can not handle "p => p.Name" part, what is it, how does it work and how can i change it to maxscript? I need it to be able to create a loop.

Thanks in advance.

Sekopasa, any progress?

I am currently looking at JSON.NET in max script as well
And I'm pretty much at the same point you were in this post

Hey Mambo4, i not try jet

Hey Mambo4,
i not try jet JSON.NET. Tell me what is the adventage ei. purpose of json.net in combination with mxs.
Cheers!

I'm writing MAX export tools

I'm writing MAX export tools for a game engine that uses JSON to load its assets.

functionally JSON does the same thing as XML, which I guess most Max tools utilize.
but it's less verbose and slightly smaller in file size.
my background is manipulating JSON with MAYA/PYTHON, so I like it better.

Jsont.net is simply the first library I found for using json in dot net. It looks powerful, but getting it to cooperate with mxs is a challenge.

Ok the project is recreating Daz Studio materials in 3dsmax/Vray at least getting the texturemaps connected to materials.

Daz Studio exports a DSF file which is a JSON file defining the materials. I achieved to get the file into 3dsmax i can reach the values by keynames.

But i realised that i would need loops in some cases. JObject has a count value but you can not reach the values like an array. I was looking for how to create a loop, i thought if i had the property names in an array i would create my own loop.

So i found this thread.

http://json.codeplex.com/discussions/231381

this is what i get with showproperties

 .Count : <System.Int32>, read-only

  .EqualityComparer : <Newtonsoft.Json.Linq.JTokenEqualityComparer>, read-only, static

  .First : <Newtonsoft.Json.Linq.JToken>, read-only

  .HasValues : <System.Boolean>, read-only

  .Item[<System.String>propertyName] : <Newtonsoft.Json.Linq.JToken>

  .Item[<System.Object>key] : <Newtonsoft.Json.Linq.JToken>

  .Last : <Newtonsoft.Json.Linq.JToken>, read-only

  .Next : <Newtonsoft.Json.Linq.JToken>

  .Parent : <Newtonsoft.Json.Linq.JContainer>

  .Previous : <Newtonsoft.Json.Linq.JToken>

  .Root : <Newtonsoft.Json.Linq.JToken>, read-only

  .Type : <Newtonsoft.Json.Linq.JTokenType>, read-only

(by the way getPropNames is not working)

I can send the code but there is nothing fancy in it. Maybe i can upload a dsf file somewhere if you like to see. You can open it with text editor.

Yep, you can attach *.dsf

Yep, you can attach *.dsf below. This is interesting.
I know a little dotnet+mxs integration but JSON is not my specialty.
I have a few questions:
#1] Tell me, you use showproperties for what?
#2] If I understand correctly what you need is to convert DAZ material to VRayMtl.Right?
#3] I try something like this

ss = stringstream ""
showproperties $ to:ss
str = ss as string
arr = filterstring str " : "
for i = 1 to arr.count where mod i 2 != 0 collect arr[i] 
--#(".smooth", ".radius", ".segs", ".mapcoords", ".slice", ".hemisphere", ".sliceFrom", ".sliceTo", ".chop", ".recenter", ".realWorldMapSize")

#1 Just to see which properties i can call
#2 Exactly.
#3 This is not what i actualy need but i didnt know that i could use "to" to store the printed values.

t1 - t3 is the most basic form of a material but for example in t5 its different. There is a "extra" slot and all the material is stored in that slot.

But i will give you a example, after i get the dsf file into a Jobject i can reach the values like below. What i need is to get the keys(strings) needed to call the values.

print o.item["scene"].item["materials"].item[0].item["type"].value
