Hi Vincent Parot,

Thank you for the kind feedback, very appreciated.

Please have a look here:

I have no clear idea what you mean by "via right, via left". Should the result be oriented to the left or right, or do you have buttons in mind?

I used a formula to get there.
?($1<628;314;942)

Which reads If the input one is smaller than 628 (half hour), then output 314 (pointing right), otherwise use 942 (pointing left)

The numbers are based on the setup; they might be different for other setups. Here, 628 was the half hour.

The Module added here was needed, as the reset to the left would always start then with 942, and the formula wouldn't work. In this way, the counting starts always anew.

Tip: while the project is not running, but the XPresso tab "run" is active – pressing the "a" key shortly moves it one increment forward, holding the key continues. (Refresh the scene "a", triggers a new run through the XPresso set up, hence the update)

All the best

Hi Mark,

Thanks for the file and for using Google.

The Light source in some cases is pretty much tangential, and the Phong Angle of 0º is not helping either. While the mesh needs some attention, more below.

However, these stripes look like artifacts to begin with; they should show up that way.

When I cmd-drag the Inlet to make a copy and switch the original to invisible, I get no problems.

When I use the
Main Menu>Mesh> Add> Subdivided in Smooth mode
With a single or perhaps two subdivides, the floor looks right.

Similar to that, the white triangles that do not receive shadows feel like a problem turning those into triangles, which happens for quads one or the other way, depending on their "bend". When I cut the one marked in one direction, it seems to be fixed, then later it shows up, whereas the other cut direction would work. That is not a fix, just an exploration.

If I place an RS Render Tag on it, switch on the Geometry and tesselation, the floor looks right.

I checked it in both cases with the Material provided, but also with a new one, while I used for the final test also Red Emission as the only output from the Material. The floor stays.

The white long triangles are artifacts in my book; they should not show up to begin with. If you delete two zeros from the Plant (RS Matrix), you can see that effect. When they get a shadow, it seems like they disappear.

As a side note, those light setups should be done with a parallel light (Infinite), while the Inlet can be used as a Target. Besides that, have you considered to use an Random Effector for the Scatter, to avoid obvious repetition.

All the best

Thanks for the reply, Pitichi.

I'm glad you found something.

I have no idea how often those things appear on your screen, but allow me a tip: joints might be more adaptable here to various meshes.

All the best

P.S.: I have had no option to see you file. If that 1MB size hits again, I open DropBox, Wetransfer, Google, Adobe or Apple cloud services. Please always the full URL pasted, no HTML wrapper.
If that is no option, I have a drop box account and I can set up an upload.

Hi Vincent,

Please have a look here:
CV4_2025_drs_25_ANsc_01.c4d

This is simplified, and you need to set the time Progress in the Multiply Node accordingly.

Please click on the XPresso to have the User Data in the Attribute Manager. I have introduced a Run, Pause, and Reset button. The current state can be keyframed. Note that you can create a second Attribute Manager to have the buttons in your view.

You can set a keyframe on Frame zero if that is the point you want to reset. While the entry in the Select-Node for the Reset (the input at the bottom) is zero, you can enter any number to reset the "clock-arm" to any position you like. On the left is the information top to bottom, which is often crucial in XPresso.

I use the User Data> Internal parameter as memory, BTW the name is not important. Over the decades, it has shown that this approach is more obvious than a memory node somewhere. This one should not be touched.

The Cloner is there only for optics, and it is not a functional component.

Let me know if that works for you. (The only drawback for this, you can't move back and fore with the Time Slider, it needs all frames )

Cheers

You're very welcome, object-kind.

Thanks for your reply.

My best wishes

Hi object-kind,

Would that work for you?

Please let me know if there are any questions.

Hi Pitchi,

Sorry there is no fix to my knowledge.

All the best

Thank you for the reply, steal-shelter,

You're very welcome.

Let me know how it goes.

Since I write in a Forum, let me add this for anyone reading along: If the amount of the Normal move is different for each polygon, the shared points (and, with that, the edges) will find a sweet spot among all. Then, the Normal direction is not the final determination of the Polygon orientation. Which means the Normal direction has changed.

Enjoy!

Hi steal-shelter,

Since you have explored the obvious "suspects" of this technique, please have a look here:

You might explore some of the MoGraph Effectors, but in Deformation Mode.

Please let me know if that aligns with your targets.

Cheers

Thank you very much, earth video,

You're very welcome.

My best wishes for your project.
