I have an object and points (point cloud). I would like to modify the named attribute of the nearest vertex to each point. How to do this?

I tried using the "sample nearest" node, but I couldn't make a selection out of the output. Then I tried it with the "sample index" node, and it seemed like it was modifying the named attribute for all vertices for each point, or the "sample nearest" node used the source object's location instead of the point cloud.

I would appreciate some help

I'm trying to learn blender for making tandril studio-like animations (the UI animations usually published by Microsoft when announcing something new like here with Copilot).

I know that's a big goal, but I still wanna do it...

This is a simple shader node group that breaks up the visual repetition of tiled textures. It uses a Voronoi texture's cell colors to apply a random translation and/or rotation to an image texture's vector input to produce an irregular pattern.

I primarily made it for landscape materials. The cells' borders are still sharp, so certain materials, like bricks, wood, or fabric, will not look good.

I recently came across a Japanese animation and love the way it looks and want to replicate the shader style and animation style

Recently I've been planning on designing some optics, nothing fancy just for a projector system that I'm messing around with. Anyway I got this idea that I could basically model the optics in blender using lux core to simulate the light path as it bounces the mirrors and passes through the lenses.

So I am able to create lenses and parts of any kind O can think of but I would love to be able to control the parts after I've created them via parameters like radius of curvature for example for a mirror.

Is that possible using a python script? Like somehow keep the script that created the geometry somehow linked to the geometry in such a way that I can come back to the script and change it later or maybe even change it using the timeline and key frames?

Hi

So, the thing I want to accomplish is to add .png images, compile them and then transform the compiled montrosity (move/scale, etc).

But the thing is, if I “alphaover” the images with some offset, for example:

the image laid over the other cuts off, as the overlay can’t reach outside the dimensions of the underlaying one.

I know I can just:

• use eg. gimp and combine the images there, but I’d rather have my workflow entirely in blender.
• add transparent padding for ~billion pixels around the decal as a workaround, but that sounds silly and “bruteforcing” the concept.

How would I go about getting all overlaid images to display in full in such case? I’ve tried different options on the “alpha over” and “color mix” -nodes without results, but entirely possible that I just missed some critical combination.

So, thoughts?

This is a remake of one of my first nature scenes; it's always so satisfying to look back and see how far I've come since then. All made in Blender, rendered with Cycles.

Let me know what you think!

I personally find this addon quite innovative. To me it looks like a 2d drawing toolset inside of 3d program that is more powerful and has unique 2d drawing features absent in actual state-of-art 2d drawing programs like CSP and Krita!

(also; an album: https://imgur.com/a/H4EZCdV - changed the topic link to show the render, for obvious visibility. Album includes node-setups for geonodes and the gist of what I use for most materials)

Hi all, I'm an on/off blender hobbyist, started this "project" as a friend of mine baited me a bit to this, so I went with it. The idea is to make a "music video" of sorts. Gloomy music, camera fly/walkhrough of a spoopy house, all that cheesy stuff.

It started basically with the geonodes (as shown in the imgur album) - basically it's a simple thing that generates walls/floorlists around a floor-mesh and applies given materials to them, nothing fancy but it allows me to quickly prototype the building layout.

The scene uses some assets from blendswap:

• https://blendswap.com/blend/14139 - furniture, redid the materials as they were way too bright for the direction I intended to go. But the modeling on the furniture is top notch, if a bit lowpoly but nothing a subsurf mod. can't fix.
• https://blendswap.com/blend/25115 - the dinner on the table. Also tweaked the material quite a bit, the initial one was way too shiny and lacked SSS.

Thanks to the authors of these blendswaps <3

edit: the images on paintings on the wall are some spooky paintings I found on google image search, but damn it I can't recall the search term to give props. I'm a failure.

The source for the wall/floor textures are lost to time, I've had these like a decade on my stash. Wish I could make these on my own :/

Good morning,

Hope this is not a stupid question, I am very new to Blender. So, my setup is:

• 3d env built from iPad photogrammetry

• we insert some lasers (a simple cylinder with emission node)

• we control the lasers using QLC+ --> artnet --> BlenderDMX and a python expression that modulates the emission color for every laser from a separate dmx channel.

We would now love to be able to store the dmx animation directly in blender as keyframes in order to export the animation and put it back on the iPad for AR simulation. Is there any way to record the driver data in real time?

My wife just finished playground asset pack for our life simulation game :)

Here are the renders in Blender:

I've often seen this sort of thing in videos advertising GI in minecraft shaders, and tried it out in blender.

Currently the elbows are pointing in vaguely the right direction but they are somewhat off. I have checked that they have the right target bone selected. I have a feeling that this is due to some of the rotations of the bones in edit mode... Can someone help me with this?

Been playing with more space stuff. Trying to cook up a TOS style Miranda class ship. I dont have the panelling where I want it but I'm pretty happy so far. Next step is animating some of the ship details like the bussard collectors and anti-colission strobes, etc.

I couldn’t find any good examples of threads generated with geometry nodes, so I made my own following the ISO metric screw thread specifications.

For instance, when setting render samples, noise threshold, or domain resolution I set it at 128, 256, etc. I've just done it this way ever since I learned Blender, but does this acutally do anything?

In addition to my last post I want to share another work with you all. I created a toy car from my exsisting model and I also made a packing for it in the style of a Hotwheels toy car packing as if they would have made it.

For the general shape of the cardboard I found a template on the internet. Apparently I wasn’t the first one that came up with the Idea of creating a toy car version of a casual vehicle. This template saved a lot of time in guessing the correct measurements and proportions.

The rendering of the car on the packing was rendered with EVEE since it must not be too realistic. The cars depicted on these real packings are detailed, but look more like a colored illustration, also there are no enviromental reflections. The glass (windshield) is opaque. I added the „Space Star“ writing to the number plate, which usually would be on the trunk door. Without the number plate the picture of the car would be somewhat empy, although the depictions of cars from genuine Hotwheels packings don’t show number plates since these are mostly racing cars - or at least not boring everyday cars.

With EVEE I was able to render the scene without any background because the rendering was put onto the cardboard design which I created in Affinity Designer entirely.

For the bilster packing I used the subdivison surface modifier for smoothness and the solidify modifier to add a little bit of thickness.

To make my car model appear like a toy car I had to apply some changes to it. The most noticeable one is the tires. I found out that toy cars only have a few basic tire designs which are shared between all kinds of cras. I made another set of tires with the help of the array modifier. Additionally to that I made the tires way wider than they would be in real life. The original car model has raher thin tires.

Another thing I did was to remove all additional things like the decals, the windshield wipers the number plates and the antenna. Also I changed the material of many plastic parts (e.g. the mirrors) to the color of the paint. Usually the scale of these toy cars is 1:64. That means the length of the car is about 6 cm or 2.36 Inches. There are not many details visible.

I changed the material properties as well. The head and taillights of reals toy models seem to be painted on, so I scaled down the transmission value and scaled up the roughness value for these materials.I changed the chrome material to a less reflective one as well.

For the composition of the packing and the unpacked toy cars I choosed a road area rug. I guess many of you had one of these - at least I had one. For the fluffiness effect I used hair particles. Since it was not possible to find a good picture on the internet I was forced to re-draw the carpet using a blurry picture as a template. I did that in Affinity Designer. Then I used that drawing as an image texture. The carpet has 8 million hairs (at 10 million my laptop crashes) and working with that many particles was a pain in the ass. I saw the spinning beach ball a lot. Maybe that is the one of the reasons why desktop computers still have a place.

For all renderings I used Cycles.

I didn’t track time so I don’t know how long all of this took me. What I can say is that the drawing of the carpet took me about 9 hours, and the setup with the hair particles took almost all weekend.
