thanks guys, that is very encouraging! :-)
Richard, no I don't think I am going to try and reproduce any real existing species. There is a whole library of existing plants one can choose from. When and if xfrog decides one day to put them on sale model by model (and not packed in one library), I and many others have a convenient way of adding real plants to our renders.
The xfrog modeller is very versatile, it would almost be a waste to limit yourself to trying and re-modelling existing species only. With a little bit of imagination, I will be able to create entirely new species, that still look realistic. Like the one in this thread.
That being said, there may be demand for higher quality (real) species, where the xfrog model just is not satisfactory. Klas' oak is a good example - he just made a better one.
Franck, the xfrog UI is so so. It looks a little dusty, I think the last update must be like 5 years ago or so. The UI works, let's put it that way. Here again, it's useful to have a fast CPU when zooming and panning in the render view.
Cheers,
Frank
