my computer problems are F I X E D!!!!!!! :attn: :attn: :attn: :attn:

anyway, I'll start working on this script on Sunday, I'm going somewhere today.

I'll take a look at the script(s) and I'll add some stuff like... well... we culd start working on mat editor and stuff.

anyway, im so happy!!!!!11 :attn: :attn:

Congratulation!!! :attn:

I was thinking about using custom nodes as material info holders
And some extra attributes in the polys to hold material name and the "Generate this" option user added image

Code:

string $indPolyObject[];
$indPolyObject = `ls -sl`;
$shaderName = "Diffuse";

$indShaderNode = ( $indPolyObject[0] + "ShaderName" );
$indGenNode = ( $indPolyObject[0] + "GenThis" );

$indSetShaderNode = ( $indPolyObject[0] + "." + $indShaderNode );
$indSetGenNode = ( $indPolyObject[0] + "." + $indGenNode );

   addAttr -ln "ShaderName" -sn $indShaderNode -dt "string";
   addAttr -ln "GenerateThis" -sn $indGenNode -at "bool";
   setAttr $indSetShaderNode -type "string" $shaderName;
   setAttr $indSetGenNode true;

This will create a Node containing the Diffuse Settings

Code:

		if( !`objExists "indigoDiffuseNode"` ) {
                                                createNode "transform" -n "indigoDiffuseNode";
$indObjectToAddTo = `ls -sl`;
			//---------------------------------------- Add Attributes

			// add a string attribute
			addAttr -ln "ShaderName" -sn "indDifName" -dt "string";

addAttr -ln indDiffuseColor -usedAsColor -at float3;
    addAttr -ln redCol -at "float" -sn "indDifRed" -parent indDiffuseColor;
    addAttr -ln greenCol -at "float" -sn "indDifGreen" -parent indDiffuseColor;
    addAttr -ln blueCol -at "float" -sn "indDifBlue" -parent indDiffuseColor;

$iotatRed = ( $indObjectToAddTo[0] + ".indDifRed" );
$iotatGreen = ( $indObjectToAddTo[0] + ".indDifGreen" );
$iotatBlue = ( $indObjectToAddTo[0] + ".indDifBlue" );
$iotatName = ( $indObjectToAddTo[0] + ".indDifName" );

			//---------------------------------------- Set Initial Values
			setAttr $iotatRed 0.5;
			setAttr $iotatGreen 0.5;
			setAttr $iotatBlue 0.5;
			setAttr $iotatName -type "string" "Wall";

		}

And to Change Attribute Settings

Code:

select -r indigoDiffuseNode; //name of material node to be selected
$indObjectToAddTo = `ls -sl`;

$iotatRed = ( $indObjectToAddTo[0] + ".indDifRed" );
$iotatGreen = ( $indObjectToAddTo[0] + ".indDifGreen" );
$iotatBlue = ( $indObjectToAddTo[0] + ".indDifBlue" );
$iotatName = ( $indObjectToAddTo[0] + ".indDifName" );

			//---------------------------------------- Set Initial Values
			setAttr $iotatRed 0.5;
			setAttr $iotatGreen 0.5;
			setAttr $iotatBlue 0.5;
			setAttr $iotatName -type "string" "Wall";

What do you think? Just connect this to the Mat Editor user added image

Anyway, Welcome back!!! user added image

hmm... looks good. it'll take me a while to understand what's going on :p

okai, from what I see, the script won't run because of multiple variables that are undeclared

but this is what I understand of it.

for each polygon object in the scene, give it a node that says "create material" and one that says "current material".

then adding the nodes to it, but why do you need

Code:

$indSetShaderNode = ( $indPolyObject[0] + "." + $indShaderNode );
$indSetGenNode = ( $indPolyObject[0] + "." + $indGenNode );

next, it checks for if the node is already there, and if it is not, then it goes in and adds attributes fr the diffuse material.
finally it gives the user the ability to edit them ??? I can't see how. (it's just me :p)

well, I'll try to incorporate this into the main script as well. Good job user added image

-The first one adds two extra attributes to the selected object

$indSetShaderNode = ( $indPolyObject[0] + "." + $indShaderNode ); <<--This is needed to set the attributes
$indSetGenNode = ( $indPolyObject[0] + "." + $indGenNode ); <<--This is needed to set the attributes

addAttr -ln "ShaderName" -sn $indShaderNode -dt "string";
addAttr -ln "GenerateThis" -sn $indGenNode -at "bool";
setAttr $indSetShaderNode -type "string" $shaderName; <<--This sets the attributes
setAttr $indSetGenNode true; <<--This sets the attributes

-The second one creates a Node to hold the Material Settings for indigo Diffuse material

-The third in to change the settings in the Node created above

Good luck scripting! :p user added image

How to set up and render a basic scene:

So let's say you have a basic scene here, like mine. A couple of polygons and a basic plane.

So you want to render this in Indigo. First thing you have to do is to create a light. Your scene won't render without a light. Now, since Indigo is physically based, you need a 3d object to illuminate your scene.

One thing you might want to consider is render time. The more polygons that you have as lights, the more time the render will take.

So then, let's make a light.
Create a plane about 2 units long by 2 units wide. Position it at an angle, facing the object you want to render

Now, we have to make sure that the light is pointing toward the object, and not away from it. Go to Display->Polygon Components->Normals. Select the plane, and you will see that the normals are facing away from the object we want to render.

To fix this, go to Edit polygons->Normals->reverse

Alright! Now what we want to do is triangulate everything. So, select everything. Go to Polygons->Triangulate. Alright, now that we have that done, we need materials. It's always a good idea to set the light materials last. This is because of some errors in my own exporting code... which I am unable to root out. So, we will assign the other materials first.

So far, only 3 materials are supported- that is, meshlights, phongs, and diffuse.
So, to let's make the diffuse material for the ground plane first. Create a lambert, and change its color.

Great! Now let's make a reflective material for the object user added image

. I'll create a mirror material, just as an example. Assign a phong with the following settings to the object.

Alright. Now lets make the light. What you should know about the lighs is that the incandescene value is infact the blackbody temperature of the object. So, to make an object emit a white-ish light, the incandescense value should be in the middle range. For a dim, reddish light, it should be low, and for a bright, blue light it should be very high.

The next thing you should know is that the material type has to be lambert. The collor does not make a difference, just the incandescene value. So let's assign a lambert with the following properties to the plane/light.

Good. Now, all we have to do is to set the render settings, make a camera, and render.

Open up MayaToIndigo, and go to create->camera. Position the camera anywhere you want.

Finally, go to the last tab on the right, and put in settings like this:

click Generate XML Code and Maya should export, and Indigo should pop up. Happy Rendering user added image

Matt, have you done anything on the script lately that you want to add to the 0.6 release? user added image

We should have it done the same day as indigo v0.6 is released user added image

Okay.

If you start on the object and material editor they should be in separate files called
mtiObjectEditor and mtiMaterialEditor user added image

Commands = mtiObjectEditor and mtiMaterialEditor

ive got everything installed, i tested their test scene to render, and the converter is all installed and im getting an error during conversion:

Error: No object matches name:

i tried naming the maya materials "one" and "two" and i also tried the default names, just "phong" etc
