Error: Could not save file

i export my animation as a .anim file.

this is the error i get

Error: Could not save file

how can i fix it. btw i am using a maya mel script called dkanim

This little tool extracts selected faces from a poly. Not really revolutionary (i’m sure it already exists), but it can be handy…

proc string [] JPL_FaceIndex (string $selFaces [])
{
	string $index [];

	for ($eachFace in $selFaces)
	{
		string $buffer [];
		tokenize $eachFace "." $buffer;
		$index [size ($index)] = $buffer [(size ($buffer)-1)];
	}
	return $index;
}

global proc JPL_ExtractFaces ()
{
	string $selObj[]=`ls -o -sl`;
	string $faces [] = `ls -sl`;
	string $selFaces[]=`filterExpand -sm 34 -ex true $faces`;
	string $firstObjFacesIndex [] = JPL_FaceIndex ($selFaces);

	if (size ($selObj) != 1)
		error "Select one object";

	if (size ($selFaces)==0)
		warning "select at least one face";
	else
	{
		changeSelectMode -object;

		duplicate;
		string $newObj [] = `ls -sl`;

		delete $selFaces;

		select ($newObj [0] + ".f[" + "*" + "]");

		for ($i = 0 ; $i < size ($selFaces) ; $i++)
		{
			select -d ($newObj [0] + "." + $firstObjFacesIndex [$i]);
		}
		delete;

		select -r $newObj [0];
	}
}

Hi community,

I wanted to share three python scripts for mental ray.

-2D Motion Vector Pass
This script creates a 2d motion vector pass and will set the render settings in order to not offset the animation.

http://www.mediafire.com/?q11v46b3zxbiahb

-UV pass + Material ID (Maya 2012 ASAP et Maya 2013)
Run the script to create the new UV pass with a material ID in the blue channel (Maya 2012 ASAP and Maya 2013)

http://www.mediafire.com/?6pr23ypbyq9f1x6

-UV / PW / Material ID (Maya 2012 and before)
For the one who hasn’t the newest version of maya, this script will create buffers and render passes for Point World, UVs and Material ID.

http://www.mediafire.com/?dnl8gwtx6o3b563

Hope it will help someone !
If there is bug or request of improvements, you can email me at : abaudoin_vfx[@]yahoo.fr

Hello
please I want mel script for save as video function

#450

Here’s a little tool to create a dome light, to simulate a kind of ambient occlusion. You have already seen thousands of scripts like this since early 80’s? Me too! Done it just for the excercise, i’m not sure i will ever use it…

//------------------------------------------------------------------------------------------------//
//this script simulates soft light - a kind of ambient occlusion - with a dome light.
//each parameter (except the number of lights) can be changed after the dome creation,
//within the main group (extra attributes or in the channel box).
//
//installation:
//- save the script as "JPL_lightGlobe.mel" in your script folder
//- create a shelf button (or launch it in the script editor) with this code:
//		source "JPL_lightGlobe.mel";
//		JPL_lightGlobe ();
//
//or (for a quick test)
//
//- copy/paste this code in the script editor (new MEL tab)
//- add this line at the end:
//		JPL_lightGlobe ();
//- select all (ctrl+a or cmd+a)
//- execute (numPadEnter)
//------------------------------------------------------------------------------------------------//


//------------------------------------------------------------------------------------------------//
//this proc returns the lowest and highest values of the globe's bounding box
//used to calculate the relative position of each light
//------------------------------------------------------------------------------------------------//

	return $bbox;
}


//------------------------------------------------------------------------------------------------//
//this proc creates attributes on the group to modify the lights values.
//color values are easier to change in the attribute editor (Extra Attributes), since there is a
//color picker and only RGB float values in the channel box
//------------------------------------------------------------------------------------------------//

Hello! Is there way in MEL to save ALL animation from the maya scene into the text file… With other script restore only the values at the every frame i need from this text file, and apply to the all objects (without animation, just the value of the keyable attributes at the specific frame) in exactly the same scene?
I need it to remove all animation from the file but place all objects ( in every frame i choose ) as it was in the file with animation.

#452

Good evening!
Just created this python script as a friendly helper for Maya scripters which executes a python command for each selected object, or for each selected pair/triple/… of objects using a renaming scheme with placeholders like this:

    orientContraint("%1", "%2")
    
   Note all "%1's" have to be selected consecutively, then all "%2's" (Not pairwise %1 %2 %1 %2..)
   
   Some extra features:
     1. Editable presets
  1. Any number of placeholders (%1, %2,…) - make sure # selected object is multiple of # of placeholders
    3. A script preview function
    4. Placeholder for iteration count (%i)
    5. Placeholder for total count (%t)
    6. Form data persisting over app restarts


   import maya.cmds as cmds
import subprocess

strPresets_init = '\
# nurbsCircleShape1 => joints, set joints draw style to node
\
cmds.parent("nurbsCircleShape1", "%1", r=True, s=True, add=True)

** edit … That code tag inserts some extra spaces before each line for me :curious:. Bad for python. Sorry you’ll have to edit them away (or use the creativecrash script)

Hello professionals,

My issue is not very complex so let me explane it with a simple example. I made a particleShape and instance it with a simple cube and set the AimDirection to velocity which make the cubes aim themselves on the surface that they emitted from. But i need them to rotate randomly on Y axis. But once i put my random rotation in Rotation`s field the Aim effect get lost. Some how them stay instead of each other i dont find a way to merge these together.

Thank you

#455

hi

sorry, maybe wrong place… but I didn’t know where to put it.

dynamics in Maya, always checks for initial penetration between objects, and most of the time It fails to calculate properly…

is there any kind of automatic way, Mel or plugin,… to help detect the penetration and maybe pull them out of each other to make a clean scene for dynamic?

thank you in advance

hey guys,

im not that clued up to mel but what i am trying to do is Make my particles return to there worldPosition over time.

basically i have particles that i have set there initial state and there is a field going though them and after the field has gone though i would like the particles to go back to there initial state position of time (over 50 frame for example).

i have seen this post but the particles dont go back over time, they just snap back in 1 frame… http://forums.cgsociety.org/archive/index.php/t-1043091.html

if anyone can help it would be great… i am really stuck as my mel knowledge isnt great…

Cheers

Welcome! I have small problem following DigitalTutors tutorial about rigging character in Maya. I’m trying to create Renaming Tool in MEL and everything seams to be ok with my script but I’m receiving such error:

// Error: Invalid object or value: -1 //

Maybe its easy to fix but i’m new to Maya so I’d be grateful if anyone could help me;)

Ps. This is my script:

//Renaming Tool

//Create the window

string $RNM_Win = window -t "Rename It!";

//Make the window a columnLayout and adjustable

columnLayout -adj 1;

//Query your selection

string $sel[] = ls -sl;

//for loop - so we can acess and apply the command to each selected object individually

for ($each in $sel) {

//Name field - acqure the name of selected objects and allow to rename them

nameField -o $each;

}

//Button on window for closing out our Renaming Tool

button -1 “CLOSE” -c “delete UI -window $RNM_Win”

//Shows our Renaming Window

showWindow $RNM_Win;

This is a little script that I wrote to create fast and easy Edge Loops in the geometry :wink:

Hey there, I didn’t try it in Maya but I think it’s because in the “button” command you have the label flag written as “-1” instead of “-l”.

One of the menus in the script editor has a “show line number in error” checkbox. Turn that on to make it easier to debug your code.

Hope that helps.

Please someone would help me with this.'s for a college work appreciate your help. thanks

Create a script that allows me to create the proxy of a helicopter (model of a helicopter in
very low poly)
 must include a general controller type Nurbs Circle function as father of all
hierarchy.
 must create an expression that allows me to assess:
 If the helicopter is on the ground not moving propellers.
 If the helicopter rises must turn the propellers. :rolleyes:
