The title of this plug-in suggests that it will populate your landscapes or arch-viz scenes with trees and foliage. And indeed it does just that – but even as a version 1.0 release, Forester does a whole lot more besides.
Lebanese developer Charbel Koueik has distilled the patterns of nature into a series of mathematical formulae, which lets you design a practically limitless array of flora, from simple grasses and gnarled trees to the most complex of fantastical plants.
Everything in Forester is procedurally generated, with a slider for every facet of the mesh. So not only do you get instant visual feedback as you alter values, you can also animate them – mainly for growth, but also for other effects.
All the controls are pretty intuitive, but there's a whole heap of tutorials on Vimeo explaining every feature and function. And, failing everything else, you can just click on one of the many presets for an instant plant or tree.
Models appear with basic textures, but it's a simple case of adding materials to each one and then using selection tags such as petal, leaf, stem and so forth to differentiate each part. UVs are handled automatically, so it's a doddle to add a texture map and alpha from your collection and generate good-looking leaves or petals.
Also, because foliage is largely based on the same poly count, you can use C4D R17's new Variation shader to add diversity to grass or leaves for even more realistic results (although it would be nice to have this hardwired in).
For animated scenes, Forester features Hyperwind, which creates the effect of a breeze moving through your greenery. Again, this previews in real-time in the main viewer (depending on the complexity of the model), and looks great. It can be a CPU-hog but the resulting animation can be cached for use in other scenes.
Room to experiment
We do have a few issues: trees are created as a collection of swept splines, but you don't get a nice smooth intersection at the joint.
Also, they're quite featureless – no lumps or knots or growths – and can't be pruned or displaced to suit, so if you need a hero model you're better off looking at the likes of SpeedTree. There are other minor quibbles, but these are largely personal preference.
Forester is a hugely impressive debut; brilliantly designed, easy to use and rock solid. With the right textures and lighting it's capable of producing lovely results – and we suspect that experimental C4D users will find ways of abusing it for more than just trees, flowers and rocks.
It sounds like the developer has plenty of features on his to-do list, so we look forward to seeing how this budding plug-in matures over the coming seasons.
