Questions tagged [constraints]

Constraints are object features, they control in various fashions the object's transform properties such as its position, rotation and scale. Use this tag for questions pertaining to constraints and their usage within Blender.

Constraints are a way to control an object’s properties (e.g. its location, rotation, scale), using either plain static values (like the “limit” ones), or another object, called “target” (like e.g. the “copy” ones).

Add object constraint to a number of selected objects

I have a large number of objects, and I wish to add a Track to constraint to each object. When I select the group of them and then add the constraint, it is added to only the active object, of course. How can I add the constraint to all selected…

Kind of "apply" for a clamp to constraint?

I have a low-poly bridge model whose poles are positioned using Clamp To constraints and a corresponding curve: What I am looking for is a way to remove the constraints but to keep the position of all objects at the same place it was with the…

Make Camera System Look at Empty

I have a camera System that is supposed to look at the empty in my scene. It should only move, not rotate. It should rotate in two parts. One, the actual sensor body and the other, mount plate. Rotating these two parts the camera should be pointing…

Restrict dimensions of cables

I am creating an animated manual for a device that has an external cable connected to it. The cable has a length (1m) and a diameter. When I bend the cable, I would like to ensure that the length always remains the same. That means, the total length…

Why is the Track to constraint "legacy"?

The tooltip for the "Track to" constraint says: "Legacy tracking constraint prone to twisting artifacts". Why is it "legacy"? Has it been replaced with something else?

Damped track : is this behavior expected?

A camera following a nurbs path and a damped track constraint : At several locations of the curve, the camera rotates curiously. But the tool tip of the constaint indicates "points toward a target performing the smallest rotation necessary". Is…

Is there a way to put a copy rotation constraint with an influence higher than 1?

I'm making a little animation with some gears. I want that if I rotate the first gear, all the gears rotate with the gain given by the gears. For doing that I've choose the copy rotation constraint. But in my case, sometime a gear turn one time and…

Follow Path: Set start point?

There's so many related questions i may have missed something. But i'm trying to set a series of existing objects that start with a pre-defined location. I want them to follow the same curve - but with zero offset. Consider the example below - The…

Keyframing Constraints - Is it possible?

So, this is all hypothetical. This isn't really anything I am trying to do at the moment, but what I want to know is how to keyframe constraints. Example: Say I have an item that - at some point in the animation - needs to be picked up by a…

Stretch to constraint using wrong axis

I am trying to make a laser beam (glowing cylinder) that stretches to a target empty. My problem is that the stretch to constraint stretches in my local Y-Axis instead of my local Z-Axis (how i need it). How can i tell the constraint to use this…

Contraints & Camtrack

I am trying to get a camera to follow a point in the X,Y,Z plane. It worked yesterday, but I can't get it to work today. I was able to follow the Book Tutorial, where he shows the setup steps: Add: (i) Camera, (ii) Empty [Camtrack], and (iii) [Ctl…

Multiple Limit Distance Constraints

I will say that I've looked at a question called, "Distance constraints between objects/vertices/edges," but it didn't help. I am not sure if this is a known bug or if it is meant to be this way, but when I add two Limit Distance constraints to an…

constraining an empty to the intersection of two coplanar segments

For some reason I have two coplanar segments (each represented by a 2 points path), moving relative to each other in a way that guarantees they are always intersecting. What I would like is to constraint an empty to follow the intersection of these…

Is it possible for an object to follow multiple Clamp To constraints?

I am trying to figure out how to get an object to follow two different "Clamp To" constraints. I am not interested in "animation only" solutions, so the Follow Path constraint seems to be out of the question. If there is an entirely different…
