With the exception of the GroundCover library, all XfrogPlants libraries have been done with resolutions that range from 20-30.000 (less for plants and grasses) up to 500.000 which is approximately the upper limit. The average is between 100.000 and 250.000 for the majority of models. These are figures that are really average, but we managed to keep the detail quality very high. Then of course there are some models that required additional geometry to look good and in these cases we raised the polycount but always having in mind the 500.000 limit. The libraries have been built with the professional users in mind - and in fact have been used in several main picture movies. They would not have been used if they were inferior resolution. Of course if you want to populate whole ecosystems, it is better to use high resolution only in the foreground, and use other options for the background. XfrogPlants offer the customer some options: 1) The owner of Xfrog 3.5 can use the reduction slider that is built in within Xfrog 3.5, and obtain a polygon reduction that looks very good and is often more than sufficient for the task. 2) With every XfrogPlants library comes a set of professionally rendered billboards, one for each model, complete with embedded translucency (premultiplied alpha) and ready to be loaded within Vue's alpha panels. 3) If there is the need of a super precise control of the polygon reduction, then there is XfrogTune available. XfrogTune is useful (highly useful in my opinion), but it's not indispensable: if you are on a limited budget, you can handle polygon reduction with Xfrog 3.5 alone.
