Nested Generators problem

[Sergey_Dobrij]

Hello everyone! It's time to learn RC4. I tried to repeat the steps from the lesson and ran into a problem. Tell me, how can I remove the clipping of the geometry? Can I get a scene from this tutorial to study? Thanks!

Faced a problem in the second part of the tutorial. The expression does not work (

[Sergey_Dobrij]

I removed clipping in the transform node, but there is a new problem. My spheres are missing

[Paul Roberts]

Hi,

Please try changing the Generator's General>Clipping Area>For No Slice property to preserve. The default setting is Remove which will completely remove any geometry sliced by the clipping spline. Preserve makes sure they are maintained.



I hope that helps,
Paul

Thanks for the answer! But it didn't quite help. I will attach my scenes, if you have the opportunity, please see them. Thanks!

Please find attached a couple of revisions. In the instance this issue happens because the individual segments in a nested generator are evaluated individually. As a result, some are sliced and some are not. I couldn't find a way to make this work so I've reverted to an older technique that involves embedding one RC object inside another. The important thing here is to turn on Nest for the embedded RC object. This allows it to be re-randomised each time it is used.



You might be interested to know that we've already changed this behaviour and it should be available in the next beta release.

In the second example, there was a small detail missing from the expression. When you are nesting generators you need to add the name of the generator before the property, separated by a full stop.



I hope that helps,
Paul

Thank you very much. I will check more and more carefully!

Now I have new problems. I opened your scenes and saw that the geometry in the second scene is broken (. What could be the problem?

[Paul Roberts]

That happens because Max's Helix object uses linear spline segments rather than curves. You can fix it by changing Bevel Mode to None in the generator so that segments aren't sliced. You could also turn off Bend and Slice for the segments to make the style more efficient.

When I'm using a Helix I often add a Normalise Spline modifier to turn it into a curved path too.

Thank you! Best regards to your team from Russia!

Please tell me, I correctly indicated here Mode - Adaptive?

[Paul Roberts]

In this case I would suggest Adaptive so that it fits nicely along the spline with no slicing.

1. Please tell me how can I implement the option as in the picture? I understand that we need some kind of multiplier for the general form, but I don’t know how to implement it.
2. How can I animate the propagation of the chandelier along the spline path? Roughly speaking, so that it grows up. Thanks!

as I understand it, I need to get the start of the spline and make a multiplier for this parameter)

HI,

I'm guessing based on your other post that you have found the solution to this issue (using the Start and Length properties is what I would have suggested). If I can help further though, please let me know.

Thanks,
Paul

Thanks! The chandelier is animated and rendered)
