Title: empty segment and sequence problem
Post by: manel_reig on July 22, 2021, 10:18:58 PM
Hello,

I have a problem when trying to use an "empty segment". The sequence node seems to not respond correctly to it. When I use a segment with geometry everything works as expected, but when I try it with an empty segment it does not work. The sequence is two elements 1 time each element. With the "empty segment" I get 2 and 1. See image attached:

I guess the error comes from the empty segment...I tried giving measurement to Fixed size and padding and none seems to work. How do I set an empty segment properly?

thank you

Hi,
What is your goal? If you want every second evenly space empty, then just double the Evenly Distance.
However, if you need sequence or compose, the Empty/Null segment will terminate Sequence/Compose. Adding some value to X fixed size should activate Null so Sequence will continue (that can be some very small value like 0.001cm).
Sometimes I use a trick to simulate Null: Add a simple geometry as a box instead of Null but set the Transform Scale X/Y/Z to 0

thanks for your answer, sadly I can not open your file, 3dsmax 2018 here...yes, the goal is to simply put a lamp and a empty segment in a sequence....sadly doubling the  evenly distance does not work in all parts of the spline, I guess it is because the arrays are in adaptative and also the evenly is in adaptative:

I tried to use the "empty segment" giving value to the pading or the fixed size...that does not work.

Yes, I am aware that are other ways to do things, but I am just trying to relearn the basics here after a while not using railclone. I used "empty segments" before, but I do not understand why it is not working with the "sequence" node..my guess is that I do something wrong, but since you tell me that and empty segment with value in the "Fixed size" should do the work... :o...

so, my questions are: How do I configure an empty segment in order to work? Can I use an empty segment in combination with a sequence node?

thank you

Thanks for reporting this. It would appear something is not behaving as it should. You can see the issue when you swap standard geometry for a null. Apologies for that, we're looking into it!

thank you Dragan and Paul...a workaround seems to be using "empty segment" variation tha Dragan suggested, scaling it to 0,0,0 when trying to use it in the evenly combined with a sequence
