Default Index - Lightwave Instancing

Hi All,
I've tried google and I've tried searching these forums but...

I'm trying to get the hang of instancing using LW 11.6

I've done a grid, I've done a ring, now I want a specific arrangement, and I'm not having much luck.

Any pointers to suitable beginners tutorials?

(I'm actually after an even square array, but confined to a circle, so evenly spaced on X and Y but forming a disk.)

Thanks,
Nick

G'Day Steven., after several years of illness and also trying to do instances with 2015, found some tutorials on lightwave3d and youtube, (link https://www.youtube.com/watch?v=lm7fHjxkIBY he is placing tress on a deformed landscape, if yu are after a specific shape, maybe get some hints from this, ie create a photoshopped shape to yiur needs and then instance on that.. might help. best luck.

Hey Starbase,


Another way is to use weight maps to control the instances.

This method I find easier, especially if you have Paint Weights where can paint he weight map right in Layout and instantaneously see the results.



Good luck,

Use a gradient for the weightmap, distance to object. Use a null if you have to.

Here's an example real quick:-



I wanted a circular region free of buildings for a dynamics crash, so I used a gradient with distance to object (the ground plane in this case) to create an area to work with the dynamic meshes.

I assume you meant X and Z, as Y is depth, but hey I've no idea what you're doing.

I've done some screen grabs which I hope help you. First has 'fall-off".



This is what I assume you were after, just move the slider with 0% weight right up to the last with 100% and you see the effect is lots of boxes, confined to a tight circle.



GL bud.
