tricera Posted April 4, 2017 Report Share Posted April 4, 2017 Hi I'm having trouble figuring out the affects curves. In the attached file, from the "Trunks" path Parameter:Length I'm trying to affect Branches->Length and also the density of the "strings" path. The length of the branches doesn't seem to be following the curve at all. I'd like the "strings" paths to start at about a quarter of the way up the total length of the object. Can't seem to get that working either. Am I misinterpreting the curves function? Is there a better way to do this? I apologise if I'm missing something obvious. Thanks!

Eduard Posted April 4, 2017 Report Share Posted April 4, 2017 Hi Mark, As I understand, you need to create an Affects from Parameter:Levels, because you're use the levels to form the total length of the trunk. Please see my fixed model: tanabataBamboo_009_fixed.max. Cheers! Quote Link to comment Share on other sites More sharing options...
tricera Posted April 5, 2017 Author Report Share Posted April 5, 2017 Thanks! So I needed to use "Parameter: levels", not "Parameter: Path position". I have a couple of questions, if that's ok. 1. Won't using "Parameter: levels" mean that for each level there will be only one length calculated? So all the branches coming out of level 1 will be the same length, all those from level 2 the same length etc? 2. What was the problem with the way I was doing it? The explanation in the Help file seems to suggest that it's possible. Thank you Mark Quote Link to comment Share on other sites More sharing options...

The explanation in the Help file seems to suggest that it's possible. Please see my screenshot: Also you can see the corresponding FAQ https://exlevel.com/faqs/#107, but there is a slightly different situation. Thanks!

tricera Posted April 6, 2017 Author Report Share Posted April 6, 2017 Hi Eduard Thanks for the very easy-to-understand screenshot. I've attached a file. How can I spread the distribution of the branches along the length of each level for "DenseBamboo_01"? In this case, I probably don't have to do it, but I'm curious and I can't find the appropriate setting. For "DenseBamboo_002", I've returned the setting to "Parameter: Path position". I thought that "Calculate all levels" meant consider all levels as a whole, but reading Help again, it looks like that's not it. Can you give me an example of how I would use this setting? Thank you!

Mark Hi Mark, Do you want to get something like this? parameterLevelPosition_002.max Also see the DenseBamboo_003 as the third version, but if you add the Random direction, it will not work. We'll consider how best to implement the generation of bamboo, perhaps we'll add some new features. Cheers Quote Link to comment Share on other sites More sharing options...
tricera Posted April 6, 2017 Author Report Share Posted April 6, 2017 Hi Eduard Thanks. I appreciate the help. Actually, my problem was solved with your last advice, although I'm still not sure what I could use "Parameter: Path position" for. I was just wondering if there was a setting equivalent to the Path distributor Range parameters also in the Path position distributor, but it looks like there are only discrete values you can set? Please excuse all the questions. I'd really like to master GrowFX. Quote Link to comment Share on other sites More sharing options...

I was just wondering if there was a setting equivalent to the Path distributor Range parameters also in the Path position distributor, but it looks like there are only discrete values you can set? If you use a continuous the trunk, as in DenseBamboo_003, and the branches are evenly distributed along the length of this trunk, then you need to use the Parameter: Path position. In this case, we set the Source parameters range from 0 to 100%. But if you create a bamboo like in DenseBamboo_002 or _01, where the trunk consists of short segments, and it's formed using several levels (Levels = 13), then you need to use Parameter: Levels to reduce the length of branches to the top of this bamboo. In this case, we set the Source parameters range from 0 to 14. Here 14 instead of 13, this is so that the last branch is not zero length.
