3ds Max Animation :: Map One Parameter To Another Using Curve
Feb 8, 2012
The reaction manager is an extremely cumbersome way to map one parameter to another, especially if you want a precisely defined mapping curve.
In Cinema4D (a program I'm learning at the moment) there is a range mapper node that can use a spline as mapping curve to map an input parameter to an output parameter.
Is there a way in Max to map one parameter to another using a precisely defined curve?

I got a deadline for my project, but I got a big problem:
"I cannot set the "parameter" for the End Value in Parameter Animate dialog"
For easy understand, let's see a example:
1. I got a part which has two parameters named: "A" and "MaxA"
2. I animate Favorited parameter A.
3. The End Value is MaxA_ (Everything is ok)
4. I finish Studio environment, then I change parameter MaxA_ from 200 mm to 400 mm
5. I turn back to Studio environment, the End Value now is "200 mm" (I want this will be MaxA_, so I can animate the flexible parameter).
show me how to keep the end value will be "MaxA_" after I change parameter?

i need to do a loop animation of several stripes that starts at lets say 2units distance from each other, they separate slowly and by the end they have 15units separation, my problem is that each stripe is a separate object, so i offset their keyframes, but when i want to tweak the keys on curve editor they dont apply to the other copies. Any other way to do this simpler?
quick example on the image attached, real application on the video, video shows the animation(rendered sequential images of 1 loop then applied as texture) but with linear speed, so constant separation, i need to apply the above here, these dont only move on the X axis but on the Y aswell, while keeping the symmetry fixed on the center.

i'm rigging a character and i want to create an custom parameter for my rig's controller that save a lot of time for animators; "transform to zero" is one of most useful command in animating, take a look at my screenshot
now my question is how can i create an custom parameter like "button" under my controller parameters or in attribute holder that run a simple code/script for me like transform to zero script: macros.run "Animation Tools" "TransformToZero"

Have a bit of a puzzle that's been bouncing around a bit. Is there a way to delay a object following it's parent for a few frames? For instance, I have a hook attached to a crane that rotates around, the hook following it around. If I could have it follow the crane at a bit of a lag, allowing the cable to curve slightly, it would look a deal more real. I know I could hand animate it, but is there a way to set it up so that the hook will follow the crane after a delay of say, 10 frames or so?

I used to do this all the time. Now I cant remember how to do it properly, if possible a screenshot of how to do the maths in the Parameter wiring box. Getting the circle to travel along this line without scripting.
What should have been a 5 minute job has turned into about an hour.

I want to create an custom parameter like "button" under my object parameters or in attribute holder and i want this button run a simple code/script for me.
for example: linking Box1 to Box2
$.parent = $Box002
I know how to work with "wire parameter" and "parameter editor" but the problem is that i cant find any way to tell them to run this script with that parameter.

I have an assembly inside of Inventor Studio. One of the parts inside of the assembly has a parameter that I would like to animate. When I select the "Parameters" function within the "Animate" tab on the ribbon, I get an error:
"There are no favorite parameters defined."
This worked fine when I tried the same thing with only the part inside of Inventor Studio, but not when the part is included inside of an assembly.

So i've rigged some characters for a school project. Now when I start animating it's fine, but when I've animated a bit (3-4 key poses) and I want to adjust things in the curve editor, the curve editor is really slow. Can take up to 3 min to adjust a block of keys.
Now the scene it self is running ok, and I'm using proxy meshes to get more speed, so I guess the problem is in the rig. Is there any way to trouble-shoot my rig, and optimize it to gain more speed?

I thought there was a way that you could select all the footsteps in biped and rotate them so that they all curved around exponentially.
Like twist links mode. Did I imagine this?

I am trying to hook some nodes of a curve to other objects. Looks like Spline IK Control modifier is a best thing for that and works great.
My only problem is that when I need to make a copy ( not instanced) of the whole curve and hooked objects the curve unhooks of those objects and switches to it's original shape.
For example I need to make a group of telegraph posts connected by wires and then copy that whole group to another place,. All the wires turns into a mess.
Is there anything I am missing? I am accustomed to use similar "hook" approach in Blender and curves stay intact there. Should I use some other way in 3dsmax?

I've got a Locator attached to a Curve with a Motion Path - the Motion Path is animated so the Locator moves nicely along the Curve. I now want to swap the original Curve with a new one and have the Locator follow it instead.
Is there a way to simply switch curves and tell the Motion Path to use a new Curve while keeping the animated keys in the Motion Path node?
I've tried playing around with the connection editor but cant manage to connect the new Curve to the Motion Path nodes "geometryPath"

How can I make a curve's end points constrain to objects in order to create a "theta" angle line that changes dynamically when the angle between the two objects changes?
I thought they answer may have lay in creating the curve using Maya's new Bezier Curve tool, then using the Rivet plug-in from CreativeCrash to pin it to the middle of two poly cylinders (the "x" and "y" axis.) Unfortunately this doesn't work; the Script editor spits back "is not a vertex!". Either I'm not using Rivet correctly or the end points of a Bezier Curve in Maya are not the same as a CV Curve. But perhaps I'm going about this the wrong way entirely.. I ultimately would wish to extrude geometry about this curve to create a dynamically changing curved cylinder to visualize the angle. It seems like it should be a relatively simple thing to do...

I try to wire the length parameter of a taper object to the local Y-Position values of another object. It works fine until I reload the file. I get an MAXScript Wire Controller Exception error:
--Runtime error: Illegal self-reference in controller script
...and the parameter-wire dialog opens. The desired functionality returns by clicking the Update Button and everything works fine again.

I'm trying to animate a simple character's neck growing along a bendy curve. The head and shoulders need to be fixed at either end of the curve. It would be great if I could avoid ugly texture stretching too.

My Animation Graph Editor is only showing one animation curve (for one attribute) at a time after I have set multiple keyframes for the character set and various attributes. I select multiple attributes, and hit View-Frame All, and it only shows the top attribute of the selected attributes as one curve.

I am doing some animations involving sine waves, and I can make an expression that controls the translation of an object such that it travels along the path of a sine wave, but I can't figure out how to dynamically create an editable sine wave curve.
Is there a way to have Maya generate a curve based upon the path that an object travels upon?
For instance I have a sphere that is moving along the X axis with time, and also moving up and down on the Z axis back and forth. I would like to make an editable curve object of this path of motion.
I can see in Maya 2012 we will have motion trails where we can see the actual path an object is moving along, and that we will be able to interact with this path to alter the animation, but what if we could take that path and make it an actual curve or NURBS object?

I have ran an analysis and SSA gave me Error 607 on the report. It says "Inlet A9 gutter capture curve is not a valid curve."
A couple things I did different from the video lectures...
I selected user define for the Tc to figure out Q. i computed those manually.
For the Inlets I have selected Maximum Capture Cutoff.
There are some inlets in this model I created that do not capture 100% of the flow so i created conveyance links to account for the bypass flow.Not sure why is not recognizing the Curve?

I am trying to publish to the CC a guide rail. The vendor of the rail gives me the option of entering the desired length of the rail. After that he gives me the option to choose between the length that I entered and a shorter and longer standard length witch can be delivered faster.
I want to do the same thing with my published part, but I cannot make a key parameter to change depending on the entered custom parameter. I want the user to make the next steps when inserting from the CC: 1- select the size of the rail; 2-select the type of the rail; 3- enter the desired length of the rail; 4- choose between the desired length and the 2 recommended lengths (I need these 3 lengths to be shown)
Is this possible?
