2D Texture Node Not Working #Mel

jayantbhatt007

Hi, I'm just trying to create a blinn material in which it has the attached 2D texture. I got some mel line but it seems like they are not connecting to the blinn material. Here is the command so far

string $myBlinn = `shadingNode -asShader blinn`;

hyperShade -assign $myBlinn;

string $selection[] = `ls -sl`; 

defaultNavigation -createNew -destination ($selection[0]+".color");

createNewOverride(($selection[0]+".color"), true);

createRenderNode -allWithTexturesUp  ($selection[0]+".color") "";

createRenderNodeCB -as2DTexture "" file ($selection[0]+".color");

shadingNode -asUtility place2dTexture;

Not sure what you're setting up with the navigation and override lines, here's a simpler go at it:

string $myBlinn = `shadingNode -asShader blinn`;

hyperShade -assign $myBlinn;

string $myFile = `createRenderNodeCB -as2DTexture "" file ("")`;

connectAttr ($myFile+".outColor") ($selection[0]+".color");

Hi thank you so much it's creating the material but not assigning to the selected object Why?

throttlekitty

Right, because creating the blinn makes it the current selection. Try this:

string $mySel[] = `ls -sl`;

string $myBlinn = `shadingNode -asShader blinn`;

hyperShade -assign $myBlinn $mySel;

string $myFile = `createRenderNodeCB -as2DTexture "" file ("")`;

connectAttr ($myFile+".outColor") ($myBlinn+".color");

Hi thank you so much this is what I wanted

string $mySel[] = `ls -sl`;

string $myBlinn = `shadingNode -asShader blinn`;

string $myFile = `createRenderNodeCB -as2DTexture "" file ("")`;

connectAttr ($myFile+".outColor") ($myBlinn+".color");

select $myFile;

AEfileTextureBrowser ("AEassignTextureCB " + $myFile + ".fileTextureName") $myFile image;

select -r $mySel; 

hyperShade -assign $myBlinn $mySel;

Hi small error came I restarted maya and run this new script it does something (Didn't assign the material to the selected object as I expected  ) But again when I run this command it worked perfectly why?

string $mySel[] = `ls -sl`;

string $myBlinn = `shadingNode -asShader blinn`;

string $myFile = `createRenderNodeCB -as2DTexture "" file ("")`;

setAttr ($myBlinn + ".specularRollOff")0.2;

connectAttr ($myFile+".outColor") ($myBlinn+".color");

select $myFile;

AEfileTextureBrowser ("AEassignTextureCB " + $myFile + ".fileTextureName") $myFile image;

select -r $mySel; 

hyperShade -assign $myBlinn $mySel;

The last line will not work. You need to do:

select $mySel;
hyperShade -assign $myBlinn;

Still the same issue any idea?

you probably need to source "AEfileTemplate" as that may get sourced somewhere else which is why it works the second time around. (C:\Program Files\Autodesk\Maya\scripts\AETemplates\AEfileTemplate.mel). Probably better to use filedialog or filebrowserdialog to do the UI for selecting a texture rather than dealing with mel files hidden.

hi seems a bit complex for me. Hi, I got this file dialog command but it's not showing images on my desktop why?

string $singleFilter = "image";

string $result[] = `fileDialog2 -fileFilter $singleFilter -dialogStyle 1`;

what error message were you getting?

Any error message you can post here?

in another version of Maya I'm getting this error cannot find AEfileTemplate procedure. I think @haiddasalami is right I have load texture through file dialog which I don't know.

Just add source "AEfileTemplate" at the top of your script should work. Don't have Maya on me ATM so can't  say what's wrong with the filedialog

Hi thank you so much today I know the meaning of source.

Do you have any idea regarding condition because when I run this command it's opening texture filedialog but when I cancel that  file dialog it's still assigning blinn material it shouldn't happen. Any idea?

I wouldn't suggest using this code as you are constantly making new shading graphs. You should probably catch the exit way earlier by asking for the texture first and early out then if the user cancelled. At the moment if you cancel you leave the shading networks around. Anywho here is a way to do the conditional check. 

source "AEfileTemplate";
string $mySel[] = `ls -sl`;
string $myBlinn = `shadingNode -asShader blinn`;
string $myFile = `createRenderNodeCB -as2DTexture "" file ("")`;
setAttr ($myBlinn + ".specularRollOff")0.2;
connectAttr ($myFile+".outColor") ($myBlinn+".color");
select $myFile;
AEfileTextureBrowser ("AEassignTextureCB " + $myFile + ".fileTextureName") $myFile image;
string $filePath = `getAttr ($myFile+".fileTextureName")`;
if($filePath != "")
{
select $mySel;    
hyperShade -assign $myBlinn;
}

Hi thank you so much sure next time i will keep these things my mind.
