ShadersPlus and ShaderOps are must-haves since they both have functions not provided in C5 that I use in almost every scene. I would recommend buying these two instead of the PowerPack bundle. These two plugins (along with Veloutfrom inagoni.com) make the Shader Room "full-featured". AnyGrooves seems a little more intuitive than the Displacement channel in C5 but maybe it's only because I've spent more time with AGrooves and it does some things automatically for you.... I recommend you download the demo before you buy and build a displacement scene twice: first with AGrooves then with Displacement and compare. That money might be better spent on another plugin.... AGrows vs the Surface Replicator: as far as I know no one has gone head-to-head comparing these two, and I'm not sure the comparison would be evenly matched. AGrows creates "strands" like hair and grass which you have the option of putting a tip object on. Surface Replicator just distributes 3d objects.... So far I've not seen anyone attempt fur like Wayne's Teddy Bear (link below) using the Surface Replicator, anyone care to try? http://www.digitalcarversguild.com/gallerypopup.php?GalleryID=71&Page=24 At the risk of insulting DCG (and Eric who is a national treasure to this community) I have never seen an image using Starbright that made me want to rush out and buy the plugin. There is a tutorial that uses AGrows to make a starfield on DCG's site (link below). http://www.digitalcarversguild.com/tutorial.php?TutorialId=12 happy shopping! holly
