Hey! Thanks for a great tutorial!

Is there a way to save this style in the User library? When I save and load it in a new scene, it doesn't work properly, because the short splines for the pile and leaning books are missing. The only way to make it work is to create new splines and assign them to the nested RailClone objects. Would be nice if this wasn't necessary.

Hi,

Thanks for the question.  We encountered the same issue so since this tutorial was released we have introduced a new feature that allows you to create 1d arrays without the need for a splines. This should allow you to use styles with nested 1d arrays as a preset.

To use this feature, instead of using small splines for the leaning and piles of books, specify a length using the X Size parameter found in the L1S Generator's properties:



I hope that helps, please let me know if you have further questions.

Cheers,

Paul

There is one small issue left - if I want to control the viewport display (mesh/box/adaptive) of the nested RailClone objects in the new scene, I need to extract these segments in the scene.

Not a big problem, but is there some way to control the display from the "master" RailClone?

Hi, I'm afraid this is a limitation when using a nested RC object that includes randomisation, because each inner object must be rebuilt for every iteration. In the past when a style like this has become particularly heavy, once set up I have set it to Display as Box manually from the object properties.



Cheers,

It doesn't work for me on vertical pile of books...

Hi Rokas,

When using the X Size, you may want to set the Stacked RailClone object to Free Object, this will mean that the books are generated on the pivot point. They were being created before but they're lost in the scene somewhere.



Because there's no spline the books are being created horizontally:



So to fix this, open the RailClone object into which they are nested, go to their segment's properties and rotate them by 90 degrees:



The style should now behave as expected and can be used as a preset :)

Hope that helps.

Many thanks,

Paul

Hello,

I'm currently following the randomised books tutorial and one feature is not behaving as expected. Even when I open the books_end_vray file the feature is not working. Unless I'm missing something (I am new to this) this makes me think that with the new RC versions something changed?

The problem appears when you rotate the books. A gap appears between the books, as if their projection doesn't allow them to keep together.

How could I get arround this?

Thank you in advance!

Hi!

Since recording that tutorial there has been a small change to the way in which RailClone handles fixed rotations. You can find an explanation of this and a couple of solutions in our Knowledge Base here .

I hope that helps but please let me know if there's anything further I can do.

Many thanks,

Paul

any chance that you can update that tutorial to mach the new behaviour?

in the knowledge base, you mentioned 2 solutions, but the first one isn`t working, that leaves us the second one with the expressions, but as a beginner, tbh I have no idea how to change the rotation angle or rotate the books to the opposite direction and it feels overcomplicated anyway.

I only work on interiors and I mainly bought railclone for books, bookcases and railings and this is slightly disappointing because you "forgot" to mention at the tutorials that the software has changed since then.

Hi,

My apologies, as I've already mentioned the video was recorded before the change in behaviour. I'll update the text though to reflect the new changes.

I've just checked with RailClone 2.6 and both techniques in the Knowledge Base work fine. I've attached the revised file for you to take a look at. This was achieved by editing the transform operator show in the screen grab below.



If this doesn't help please feel free to upload your version and I'll see what's going on.

I hope that helps, please let me know if you have any further questions.

Many thanks,

Paul

thanks for the quick answer :)
it works in your file so I guess I my setup was wrong.
it seems that if you increase the angle of rotation, the overlapping area is increasing too. apart from that, all the books are rotated in the same way. I guess for both problems, the solution is to use expressions with the `arithmetic` operator. it`s not a big deal though, this version is fine in most cases, so thank you very much!

---
it seems I forgot to change the mode to adaptive on the rules panel of the L1S generator. :)
