Grow weights with nodes - shows how to use memory node for effects like this 251_Grow_Weights.c4d

Simple particle packing. Particle node modifier is used : ) 12_Particle Packing.c4d

Scene nodes are experimental, expect issues to arise. For attachment system to work one needs to be subscribed member. Afaik that is one of the rare restrictions forum has for non subscribed members, site costs to run and maintain.

Getting a point selection into node system would be fist thing that pops to mind. Then, one could connect the points based on angle, distance, or check for intersecting segments - haven't tried it though 🙂

@Eudes Fileti Maybe you missed my second scene in above reply? That is projected lines which is independent of topology. As far as topologically based one goes, that would be using mesh points to construct a spline using any available method

@Eudes Fileti Modeling the saddle should not present a problem. First thing that pops to mind is bezier object, here is an example bezier_saddle.c4d Unless you need real, mathematically correct saddle surface? Also doable, but requires some effort. The animated lines solution depends on some details. Are the lines to follow actual topological structure of the mesh or they can just be projected? If they can just be projected then projection deformer with a swept triangle spline (animated sweep end) should do bezier_saddle_0001.c4d Hope it helps 🙂

@Freemorpheme Hide it with MoGraph selection. Select Fracture, use MoGraph selection brush, from MoGraph menu go hide selected, then you can keyframe the newly made effector (strength)

@Leigh Richert Members without subscription are limited and have no access to attachments system or plugins. They can read and write posts though. Community runs strictly on support from members in form of subscriptions and donations

That seems to be due to your subscription missing

@filip Please share the scene so other members can benefit as well

Yes, unfortunate, but community can't run without some funding and I am happy that I can contribute monthly, it is peanuts really. Most of people are not really into habit of being thankful in any way for assistance, scene, advice, guidance or information that helped them quite a bit. Good thing is that now it is getting less and less restricted with new management, there seems to be just a few restrictions that are present now Rob @Corebot?

@3DKiwi Nice to see you hanging around here, was wondering if you are still somehow in 3D world : ) Still biking?

This shouldn't be problematic, here is a simple example, if I am missing something please attach a simplified scene file so we can see what the issue is rand_target.c4d

Hi and to the forums Can you please post the scene file as attachment here? Users are vary of downloading from elsewhere - thanks Regarding your question, you maybe rather want to use MoSpline with some turbulence and gravity instead of dynamics if you want the appearance of dangling

Lava Lamp with particles, not as good as fluids would do but it good 🙂

Here is a spirit level with bubble that reacts to slope 255_Spirit_Level.c4d

@hyyde Baking seems buggy a bit, however, It seems that if you bake all into keyframes and then clean up the scale keyframes (remove keys and set scale to 1) it is all good?

@Scott Williams There is a full set of boolean logic, conditionals and flow control which Xpresso doesn't have which include LCV, memory node and ranges. It is by far more powerful and versatile.

@Scott Williams Nodes are quite new environment with which you can create, well, pretty much anything. It offers node based programming paradigm as Xpresso does but is buy far more capable. Not only is capable of logic, it has tools for flow control, structures etc. Check the basics here on yt channel https://www.youtube.com/@CORE4D Also, there is node file pit present here where you can get a good idea of what they are capable of https://www.core4d.com/ipb/forums/topic/117017-scene-nodes-capsules-file-pit/#comments

Both 🙂

On port, once exposed in Xpresso is requiring a trigger and is only processing the data while trigger is true @Scott Williams Just out of curiosity, why aren't you using nodes? It is far more advanced and offers vastly better functionality and versatility than Xpresso.

Hard to help without actual scene file. Motion clips do have some bugs in them though...

Please attach a scene file, will be easier to help

So it fails locally for you? Can you post the scene?

@Eudes Fileti No problem. I see that your profile states v2023, it could be that you already have grid capsule asset. Press shift+C in viewport to open commander and search for grid. It is a node based asset which is fully parametric grid object. If it is not there then your version is too old. Alternatively, use a cube and set the subdivisions to desired values, convert the cube, select all edges and convert them to spline by right clicking and doing "edge to spline". Issue is that you wont have internal splines of the cube (just outlines) but you can do some manual work by copying another cube, converting again and connecting the splines. To connect splines select them both and put them under spline mask object (there are boolean operations to choose in the spline mask itself). Hope this helps 🙂
