Animate the children. As intimated in question, cannot animate the hair particle count. Can however set children and animate the child count. Sliding the child count viewport display amount, similarly set the render So for example I want to have like 2000 particles on frame 100 and want them to reduce to like 200 till frame 300 Example for this case, set ...

Found a solution using this related thread https://blender.stackexchange.com/a/32540/31246 and this How do I add keyframes to a newly created action with no associated objects? (thanks @batFinger) Here is the resulting code where i already have a bunch of variable (frame, value, data_path, array_index, handle_left_type) : # parent is the object/node_tree ... ...

I found a work around. First I open up the file that does NOT contain the object that I want to import. Then I go to File > Append. In the dialog that comes up, I navigate to the .blend file that contains the object that I want to import. I open this .blend file in the dialog box and it actually opens like a folder. Inside it are many directories ...

If you select a point of the F curve you can read its values on the view tab on the right of the curves window (just under modifiers). I'm assuming that your first keyframe you want to copy is frame 3, value 0.7, and the last is frame 65, value - 2.3. So you want to copy the curve with an offset of 63 frames on X and a value of 3 on Y. So select the curve ...

I'm assuming that the hand is leading an IK chain. If so you can use shift S to put an empty in the exact loc of the hand in fig.1, copy the hand bone rotation, set the empty as child of the gun, then set a copy transform bone constraint on the hand, pointing at the empty. In this setup you can animate the influence slider of the constraint, so that when the ...

Consider adding another Child Of constraint, but put this one on the hand itself, and for the target, make an empty or bone that has been placed near the hand rest position (and which is also parented to the gun). Keyframe the influence slider for this "hand rest" Child Of constraint so that the slider is in the fully off position when the hand is ...

Yes - it is certainly possible but also wholly dependent on the complexity and nature of the animation you want to achieve. For example, you could produce a 2-minute animation moving simple primitive types (such as cubes and spheres and donuts) about on the screen within a day. Alternatively, it would take months or years to fully get to grips with creating ...

The gizmo appears at the origin of the object. Always apply Transforms CTRL A before shape keys because its good to have Ref. points at 0 when starting. For now, just SET ORIGIN to C.O.M at the object mode.

So, when you generate objects, you made them without normals. I don't want to say, that they have no normals completely, because mesh can't be without normals. What I see, that all normals are rotated in the same vector, so your objects look completely flat: But what causes the jittering in colors? This vector is different from one object to another. This ...

I've only done 4 coins here. See if these physics settings work for you. You can see those in the Blend file below. Make sure to check those for the slide and pusher also. You'll notice that all coins have much the same settings, except Coin 1. (leftmost) Varying those on individual coins will obviously affect their behavior and can be used to break up ...

Make sure the big(the one on the bottom) mesh's "shape" is coming from mesh, not convex hull: I've posted the blend if it may be of any help:

I managed to fix everything by just making another skeleton using a different hierarchy.

Animate the modifier props. To elaborate on @Gorgeous' comment. Make your mesh, for example sake added a default circle, then grid filled. Note to self, rotate after grid fill to match axes before adding shape keys in future, Create your shape key from this.

You could try rendering without the GUI. I had found the following python script, which worked well, on the youtube channel of Chris P when I had crashes rendering animation nodes scenes : import bpy start_frame = 1 end_frame = 180 fps = 24 path = 'C:\' for frame in range(start_frame, end_frame + 1): bpy.context.scene.render.fps = fps bpy.context....

This is a good case for the "Join as shapes" operation, which will make a shapekey from an entirely different object-- provided that both objects share the same topology. Make your object, leaving the modifiers live. Duplicate that object, then change the bevel modifier as desired. Apply all modifiers to both objects. Then select one object, ...

no OBJ does not support animations, check more about all the specifications about .obj here: http://paulbourke.net/dataformats/obj/ I suggest using FBX (.fbx) or Alembic (.abc) for importing object with animations

The only known supported format for particles is alembic cache (.abc) which can be loaded as package. As stated on the unity page, it does support particles and possibly animation: https://docs.unity3d.com/Packages/com.unity.formats.alembic@2.2/manual/index.html Whenever possible though try using the native system instead of a loaded cache as this may be far ...

It looks like you might have two armature nodes where you only want one. Look into this possibility. In my experience, double transformation weirdness can often be traced to having an extra armature node that was created accidentally. This often happens by the old armature node not being deleted before trying to rebind a mesh. An armature node will be ...

I found a solution for myself. However, it regrettably does use bpy.ops. If anyone has a solution which does not use bpy.ops I'd gladly take a look at that answer. Here is the blend file for anyone who wants to take a look.

Personally, I only use one file with different Blender Scenes for my different sets and an "edit" Scene that pulls all the others to do the editing. The main inconvenient is that the "edit" scene preview has a crazy slow playback speed, something like 4fps. Also working with audio and timing can be more complicated. The advantages are ...

If I understand from the video what you're looking for, it seems that the last L shaped block is rigid, having only the wheel rotating, so it should work if you set the IK chain from its start, not from his tip: you can create a "master" bone for this whole object, lock its Z loc and X,Y Rot and use it as target of the IK chain, so that animating ...

I generally create an empty grease pencil keyframe (something like a single dot out of camera) and i move it at the end of the scene, so it acts like an "off" button for the active object. Hackish, but it works.

In order to reproduce the effect it is useful to know how it would have originally been produced. At the time of the original effect being produced (early 1970s) there were not the digital tools available now. All video effect would have had to have been produced either via completely manual processes or via analog video editing techniques. In this ...

This is a duplicate question, but it’s a duplicate of something I asked. Yes, thankfully you can easily limit how bones behave with IK. Go to the bone properties tab, and look for “IK settings.”

If you use Bone Constraint between bones, you need go to Pose Mode.

This is a (straight) pipe modelled as a curve, using its native Bevel, mapped in its own UV space, deformed along its X by another spiral curve, using a Curve modifier. Translating the pipe along X with respect to the spiral's origin moves it around the spiral. That's a lot of curves :) the straight pipe could have been a mesh.

If you need to align the Empty with an edge you set the snapping to Edge, affect rotate and translate and also turn on Align rotation to target This will snap the Empty on to any edge and also align the axis along that edge.

You can add an "Empty"-object to where your 3D-Cursor now is. This you can rotate so that one of its axes aligns with the desired axis of rotation. Then, select the door, select the Empty and press "Crtl - P" to parent the door to the empty. With the transform mode set to "Local", you can then rotate the empty and the door along ...

Png does not work with cryptomatte, as it requires a 32bit float precision which PNG can not provide. You must use EXR in float32bit ! Blender will save out either a OpenEXR or OpenEXR multilayer.

The usual workflow to export animation with constraints is to perform the animation in Blender, then select all deforming bones and bake the animation (Pose mode, pose menu, animation, bake action), visual transform, delete constraints. In this way you'll export an armature with no constraints that can be accepted by all others softwares. Be sure to perform ...

Normally, FBX animation data is embedded into the model. You might try reimporting the FBX and checking the preferences in the import window to include animation. It looks like the armature is parented to the model, so what you can do is download BVH retargeter and use that to retarget copy the animation data from the animation to the armature in your ...

This depends on your frame rate. One minute = $60$ seconds. To know the frames needed for a minute at a given frame rate (FPS) is a simple multiplication: Frames Per Second X $60$ = number of frames in a minute To View the Frame Rate, go to the "Output Properties" on the right side menu below the render settings. there is an option of Frame Rate. ...

There are utility python methods for this How many frames will depend on the frame rate of your current scene. The frame rate is determined by the frames per second integer fps and the frames per seconds base fps_base so actual frame rate is fps / fps_base Fortunately the devs have given us a convenience method to work out how many frames or how much time. ...

Alright, so that was weird. I discovered there were two plain axes in the scene. I thought they were just leftovers from some previous tests, so I deleted them, thinking nothing of it. Turns out the thumbs of all things were completely dependent on them in order to look correct. I searched the library but couldn't see how these connections were made (I ...

One possible solution to your problem is to manually assign and remove vertices from the weight groups. having very little geometry as you do, it should be fairly simple to tweak the weights based on the geometry. This can be accessed through the vertex group panel (upside-down triangle) Based on your description I cannot tell if you have tried this yet or ...

Two options: Assign all verts in BigCube to a vertex group. Give SmallCube a copy location constraint, targeting BigCube and referencing this vertex group. Give SmallCube a healthy Goal value (or group). Join BigCube and SmallCube into a single object. Create edges (only) between BigCube and SmallCube to create forces between the two. These will act as ...

The passport is made from a dissected cube with one half hinged up a little from the fully opened flat state. The paper is from duplicating the two upper faces of the green cover and separating those with 'P' (in Edit mode) so paper and cover become two individual objects. The paper is raised a little so it's a whisker above the cover, then parented (CTL-P) ...

I am not sure... But this happens to me sometimes (quite often) and I eventually realized that the problem isn't always in pose mode - it lies in bone edit mode In short See if they look the same in edit mode This might not be the problem, but give it a shot.

I would recommend using a fabric simulator, and having sewing holding the pieces together until they hit the bottom, where you animate the sewing strength to zero.

In pose mode, select the bones you wish to reset. Use a "hide selected" operation (shift h for me) to hide all other bones. Open a graph editor view. Make sure "only show selected" is enabled, in the upper right corner of the graph editor. Click on the "filters" button and enter "location" (no quotes) in the "...

It's not really a different style of armature. It's just an armature without meaningfully placed bone tails. The essence of a bone, for skeletal animation purposes, lies in it having two characteristics: An origin about which it can rotate (and/or scale; translation doesn't really need an origin); A hierarchical structure from which it can inherit a ...

Go to frame 266. Select your rigid body. In properties/rigid body/physics/settings, check Animated and keyframe it. Go to frame 267. Uncheck Animated and keyframe it.

If merely entering then leaving edit mode on an armature leaves lasting changes to your pose, then you probably have a dependency loop-- some place where bone A depends on bone B which depends on bone C which depends on bone A (for example). That's not going to work. To rule in/out dependency loops, open a console window (from main menu's "window" ...
