Per my conversations directly with the IDV folks (the parent company), meshes generated in Speedtree (ST) are definitely restricted from redistribution except in a shared workplace environment where every user possesses a license, and highly doubtful that any resale would be approved.. This is a discussion that has appeared in this forum in the past. Undoubtedly folks have abused the terms of the EULA, and I imagine IDV isn't keen on policing every violation. They (IDV), claim that even altered geometry of ST meshes can be identified as an ST mesh, maybe that's true. ST is an industry standard for both Gaming and Motion Pictures, with all of the awards you can name. With the elimination of the "Studio Modeler" version and the switch to a subscription fee model, IDV pretty much abandoned the "Hobbyist" market. Visiting the IDV site these days, so much of the activity is centered around the versions dedicated to Unity and Unreal (and Lumberyard). At nineteen dollars a month and frequent sales on tree/plant types, that seems to be the sweet spot market-wise, especially considering Unity and Unreal are free. A better solution for tree/plant assets for TG users may lie with an old Planetside competitor: e-on. The ability to model and procedurally change the asset attributes by size, age, seasonality, wind influence, etc, and create an endless variety of high quality objects is what ST does, but so does the The Plant Factory from e-on. e-on, unlike IDV, has an arrangement to allow tree/plant creators to offer their models on a company sponsored online market. e-on offers a free utility called "The Plant Factory Exporter" that loads the Plant Factory object and allows the user to modify the object by all of the above mentioned features and 'randomize' the results. The objects come with all of the maps, and include the seasonal variants. I have licenses for both ST and TPF, and while I prefer ST to work in, the plants from TPF are quite impressive. There is a problem currently with the e-on site and it's online market, but I've had recent conversations with e-on and they hope to be up and running before years end. I can provide the Exporter link if anyone has a TPF model they want to mess with. The plants should be available with the resumption of e-on's full site (Cornucopia 3D). I've attached a few images rendered in TG of modified TPF trees. These were all made by a TPF artist named Frederic Bec, and were $20-25 US dollars each. Not bad considering the thousands of variations each one can provide. Not intended as sales pitch for sure, but having access to quality assets that can be modified to fit the scene for a reasonable cost is a cool deal.
