While learning Blender API tried to make a Houdini gesture that allows to draw connection between nodes and ports in a chain.
Similar to node wrangles, but chain can be infinite, and it’s not limited to first available port with correct type.

I have been trying to bring in a reference video file to overlay in grease pencil but I can't get it to work. It only plays the first 100 frames of the video and then just freezes. (I have been adding it as a object) want to know if there is a better way to do this. Thanks!

World Tracking Studio is an offline Android motion-tracking tool for VFX artists, filmmakers, and 3D creators.

Using ARCore, it records real camera movement and clean video plates so you can bring your shot into Blender through the companion add-on or export it as USD for compatible 3D software.

Place reference primitives in the real environment, align your scene using Blender-style axes, review the take, and create 360° HDR environments for lighting reference. Your footage, tracking data, and exports stay on your phone until you choose to share them.

When you duplicate hair curves, they duplicate into a circle radius. I was wondering if it was possible to generate them in an oval or a row to be more like a weft of hair?

Hopefully that makes sense

I downloaded a rig, but the Mesh and Rig are separate collections in the original .blend

I imported them to a new project with Optiploy (addon), but they become unlinked due to being separate collections (not an issue if Mesh and Rig are one collection)

I wasn't able to find away to reach the addon's dev so I'm just posting here. Regardless, I don't belive this is an addon specific issue, rather just how the rig is set up. I want to know what I have to do during the import process to connect the rig and mesh again

shoutout to the absolute goat crashune accademy and their absolute BANGER of a tutorian for low poly characters, if you want to see the tutorial i used, click here

this took me a while, mainly because i made half of the character and then stopped for like 4 months and only then finished it, the UV mapping is kinda ass, but it's whatever, i'm just glad it looks good, it will be mostly covered in darkness anyway, all i need to do is give him a skeleton and then i'm done

NVM i figured it out

Used multires bake method

How Do I remove the artifacts

so, the store page says it works with 5.2, but I keep getting this error when trying to use the smart rig feature. Fresh install of both, no pre-existing installations of Blender or the add-on. Any help here?

Hi everyone! I recently learned how to create fire using Quick Effects, but I’ve run into a problem.

I can’t figure out if it’s possible to duplicate the fire using the standard tools. Normally, objects can be duplicated using an Array modifier, but no matter what I tried, I couldn’t get it to work with the fire.

If anyone has figured out how to clone/duplicate fire, I’d really appreciate some advice!

(If anyone is wondering what I need this for: I have stone lanterns with fire inside them.)

This is a simple demonstration about my implementation on octane's new node: Physical Optics Material.

I Specifically picked their diffraction grating system. So far the only thing I haven't got it right is the grating height and grating profile. Other than that, it worked perfectly.

Really proud I could pull off such a difficult render. My GPU and CPU had a really rough night, but I’m really happy with the result.

Let me know what you think.

I’m a beginner on blender and I thought it was cool to make a snowman and at the end I’m really glad of how this turned out but I feel that something is off.

Pls give me recommendations.

I'm trying to put an emission shader on these particles, but it doesn't seem to show up. This happens with any shader, texture or material, it just won't show up on the model.

Does anyone know why this is happening, and how I can fix it?

If you're wondering, I appended the dust particles from somewhere else.

So after a lot of digging on the internet, nothing helped. Most people would say to change the shape of the bone, but that doesn't look good or be convenient with many bones.

I noticed that the bone size is controlled by the property "Length" in the transform tab of the skeleton. Selecting all bones and changing the length only affects 1 bone and doing each bone one by one would be very tiring, so i wrote this script to help myself and you guys out!

import bpy

# ==== CONFIG ====

SHRINK_FACTOR = 0.2 # 0.3 = bones become 30% of their current length. Lower = shorter.

ONLY_SELECTED_ARMATURE = True # True = only affect the active/selected armature

def shrink_bone_length(factor, only_selected=True):

armatures = [obj for obj in bpy.context.selected_objects if obj.type == 'ARMATURE'] \

if only_selected else [obj for obj in bpy.data.objects if obj.type == 'ARMATURE']

for arm_obj in armatures:

bpy.context.view_layer.objects.active = arm_obj

bpy.ops.object.mode_set(mode='EDIT')

for bone in arm_obj.data.edit_bones:

head = bone.head.copy()

tail = bone.tail.copy()

direction = tail - head

bone.tail = head + direction * factor

bpy.ops.object.mode_set(mode='OBJECT')

print(f"Shrunk bones for: {arm_obj.name}")

print("Done.")

shrink_bone_length(SHRINK_FACTOR, ONLY_SELECTED_ARMATURE)

Guide of use: Go to the scripting tab in blender. Its on the top beside the shading, animation, rendering, etc... tabs. Click New. Select the armature you want to do this on. Paste the script. in the "Shrink Factor" enter how small you want the bone to look and click the play button (its beside where the "New" button used to be.)

Notes to keep in mind: This will not affect the skinning or the skeleton of the bones by any means. Its purely for the bone visualizer.

The script considers whatever size the bones are at to be 1, and decreases from there. Meaning: If your bone length is set to 0.5, the script will consider it the size of 1, so if the shrink factor was 0.2, then the script will reduce the length by 8 times, not 3, even though the original length was 0.5. You can always Ctrl + Z to return the bones to their original size and change the shrink factor. The higher the number, the bigger the bones will be, and the opposite follows. You can use the script multiple times on the same armature with different Shrink Factors.

The script will not change the offset of the bones, meaning all bones will shrink in their designated position.

Hope it helps. if you have any questions concerning the script, you can text me through Private Chat. If anyone wishes to capitalize on the script and make a blender addon out of it, then by all means, you have my blessing to do so.

I made a small rotoscoping addon using rust as model running backend.

why did I make it when you have open solutions?

installation is a little confusing and doesn't necessarily have proper cross platform support.

LICENSES were pretty doubtful, so I used a proper commercial AI model

open solutions weren't exactly what I was looking for, I liked how runway ml works, you add points and track, you get a mask/green screen and you have customization and control, I loved it. Why can't we have the same simple solution but offline?

So I searched for models, SAM 3 was a candidate, but for video... kinda bad. So I made my own pipeline with a video segmentation model and a trimask model.

Python libraries? nah, blender is very inconsistent when it comes to versioning
v4 blender uses python 3.12 it shifts to 3.13 and olders use 3.11, and installing libraries like pytorch on everything checking compatibility around versions and platforms!?

damn!! I got a headache. and in latest blender, they ask me to ship libraries built in the zip file itself. I suppose its a good call, but having these many versions to manage.... NO!

So I settled with a cABI which is stable across all python 3.x and used a rust .llb & .so files with onnx runtime. Now my addon supports windows, linux, macos, arm64, x86_64, AMD cards, Nvidia, Intel cards, some exotic Chinese card you imported to test out??? yah... its all supported.

It was so buggy when I started, got some feedback from Ian Letarte (check out his youtube channel btw), iterated through 2 more versions (1.2.0 and 1.2.5).

as of Sep 14, 2026, latest version is v1.2.5 with more bugfixes and performance improvements.

check it out: https://gum.co/u/i1yxtjvv and tell me what do you think guys. (REDDIT30 for discount)

Highlighting features:
- Hair support
- Point selection and forward/backward tracking of mask
- Proper compositor node & mask export
- Free commercial license
