Animation Nodes

My bad, different project.

Because all faces are transfered to one single mesh object the whole mesh has the same color.

With the standard “Set Vertex Color” you can only color the whole mesh with a single color. I wrote a node a while ago, though witch lets you color a mesh with multiple vertex colors.

You can grab it from here:

There is a tutorial on how to use it in post 3169 of this thread:

Animation Nodes

Hi, here is the blend file, an image with explanation of the AN node tree and an explanation of the scene in text form as well as the material. Note: When opening the file it will not look right. You first have to select the object “Suzanne” and turn its subdivision in the subdivision subsurface modifier to something higher ( I used 4). I had to turn it down because of file size issues with higher subdivision numbers when uploading the file. You will also have to plug some HDRI into the …

Good day,

        I saved a rendered animation video and I want to replay it but I can't seem to. I save it in a folder but all I can see is 100's of Png picture. Please how do I play back the animation

Does anyone know how to scale an object that is fed into an instancer?

Lets say I have a box that is 1 unit and fed into an instancer that instances it over a grid. Now I want to scale the box object down to 0.1 unit so that all the instances are also 0.1 unit.

I tried modifying the mesh data by decomposing and composing (and also trying bunch of matrix transforms etc) it back then feeding to the instance but that does not work.

I can definetely modify the instances inside a loop, but I am wondering if I can actual modify the main object (or its mesh data) in the node tree in a way that also affects the outcome of cascading operations like an instancer.

Hi there,

this is a node setup that works for me. The Instancer gets the standard cube with it’s standard size. (Visibility hidden)

The distribution matrix is decomposed and composed again, but with the scale from the value you want.

Hope this could help

Hey thanks for the node flow. I see how you do. I was some how trying to do it through manipulating the node flow that goes from an object node input (instead you directly selected the object in the instancer.)

Your set up will definetely work for me.

I guess I am wondering if it is possible to do this by directly manipulating the origin object along the way? For instance say you have object input node (that selected cube) then fed to instancer. is it possible to maniupulate the mesh data between the object input node and the instancer such that resulting mesh changes are also reflected in the final node flow, exactly how you did in the alternate matrix setup?

thanks

Hey there,

manipulating mesh data without a loop depends on finding nodes that support vectorization. That means if they are able to process lists. The nodes I found for manipulating mesh data (Object Mesh Data, Mesh Data from Object) don’t support that. (But may be there are some I overlooked that do it.)

Generally you can do a lot without loops by using vectorization, but at a certain point you’ll probably have to use loops.

Thanks, that makes sense. Your recommended solution works for me at the moment.

Any news on AN for blender 2.8?! I saw theres a 2.8 branch on github!?

[greenorangejuice]

I think animation nodes will be replaced by everything nodes in the future (not yet in 2.80). Until then I doubt AN will be ported to 2.8, because the developer for everything nodes is jacques lucke.

[drgci (Jaba)]

Yeah I think in the 2019 they will add some new features in blender 2.81 and 2.82 and 2020 they will start everything nodes project

Thats why i asked, It seems he is working on a version for 2.8 now!

[dimitribastos]

I really wish Animation Nodes ported to 2.8. It would be really bad to have to use 2.79 in order to use it. And Everything Nodes seems like a 2020 project.

[pecador]

It seems that porting is almost complete. Ohmar is using a ported version on Stackexchange. There seems to be one bug with particles on 2.8 that gives errors with AN particles systems. Once this bug is solved, ported should be almost completed.

[dimitribastos]

I hope so! Animation Nodes can be a really important module of Blender!

[Jacques_Lucke]

Omar is currently updating AN to Blender 2.8 in his free time. I don’t know how long it will take to get everything stable, but I think we can at least publish a test build of AN for Blender 2.8 within this year.

[BlenderWillie]

Hi Jaques, thanks for the good news and thanks to Omar for doing the work. Blender 2.8 without animation nodes would be incomplete to me. Hope a lot of comunity members donate to support your efforts.

[drgci (Jaba)]

Agree animation node is a must for blender 2.8
Hopefully they get the job done

Question: Is it possible to bake animation nodes output so I can just throw a thing into 2.8 eevee?
I’m driving material emission strength via AN, but would like to use eevee’s bloom features for rendering.
