View Full Version : Instancing vegetation...

05-28-2015, 06:52 PM
Hey all,...

I've been scouring the forums and have come up with conflicting things, changed things, and general lack of direction on somethings I'd like to do for instanced vegetation.

There are a few things I'm trying to do...

One is offset a bunch of wheat growing over time (so that the growth happens somewhat randomly based on either a morphing object or a keyframed one).. the time offset no longer seems to work.

secondly, I'm trying to grow grass outwards radially, or from left to right in a wave like fashion based on a central point, or a weight map...

Any general direction you can point me in here?

I can sort of do what I want using multiple instances in different places, but it's not ideal.

Any help is appreciated.

Hi Steve!

Well if you are asking for time offset for instances like in HDinstance plugin that sadly is not part of LWinstancing. So to get similar setup (with lot less control) you need to use various meshes with baked *.mdds to simulate that offset effect, requires lot more planning/tweaking and it' snot that flexible but no other way so far.

Hey Lewis,..

Thanks for the reply. So something as simple as growing grass from left to right using a time offset is a no go? Does the time offset even work anymore? (I saw dwburman's tutorial on the time offset, but it doesn't seem to work like that anymore). I feel like I'm missing something.

Hope you're well buddy.

Mr. Hurley's Newton Dynamic's Engine Plug-in
called Advanced Placement, may hold the answer,Albeit
at Extra Bucks,but it a tour de force of a plug-in.

See Shrub Tool & Others

If not available, Time off-set that is, then Ask him.

Thanks Ian,.. yes I'm quite familiar with Advanced Placement... a wonderful piece of code.

I'm just struggling to come to terms with why (and what my shortcoming is), the native instancer cannot do what I'm trying to do.

Imagine if you will a table. You have a cube at the left most side that starts off squat, and grows taller over a few seconds. You want that action to be instanced across the table with some control. You cover the table with the cubes, and you'd like that grow upwards to start on the left of the table, and be offset as you move towards the right. So it would be like a wave of the cubes growing from left to right.

I have played with using nulls to drive scale by "distance" to, but that's not really a solution.

There are two offset properties in the instancer, but they don't seem to offset anything except all the instances motion to the original. That is not a true offset "tool" as it is a global shift of everything at once.

I can't see how to do this easily... so I'm seeking some insight :)

Talk soon.

@Igu4n4 have you seen this http://forums.newtek.com/showthread.php?146813-Two-instance-centric-animations is it what you are looking to do?

Rather than using Instancing, I think you might have better (or at least easier) success with a distance based/image map/w.map controlled morph.

will something like this work?

search for the rest of the tutorial in bryphi77's channel
this is the first one
