Ok, let's sum it up again after your great input. *** Challenge name: "The Drawing of the Tree" *** Challenge purpose: to gather a considerable amount of tree objects that will be available to all the community when the challenge ends. *** Challenge basic rules: 1. The scene must be a depiction of nature (landscape, lake, waterfall, forest, woods and so on) 2. The scene must contain AT LEAST one tree created in the Bryce TreeLab. Painted trees and 2D trees are allowed, but only if there's one original treelab-created tree in the scene. B4 users can use the trees that come in the object presets tree section or use one of the links provided by Zhann --- here they are: http://calyxa.best.vwh.net/pearl/miracle.html http://www.j.b.allen.btinternet.co.uk/bigsite/treetut1.html http://www.j.b.allen.btinternet.co.uk/bigsite/bigtrtut.html http://www.j.b.allen.btinternet.co.uk/bigsite/ground.html http://www.j.b.allen.btinternet.co.uk/bigsite/forscene.html http://www.billmunnsgallery.com/xtreetut.html http://www.billmunnsgallery.com/treetut.html http://www.brycetech.com or the tree generator pointed by Rayraz --- here's the link: http//:www.treegenerator.fr.st/ or the B4 content CD or other resources that provide similar models (specifying them in the posting, of course). 3. The scene must be lit and atmosphered with Bryce SkyLab and sunlight. I think Bryster's right saying to not allow any other illumination, so SkyLab will be. In night scenes, the use of other light sources is left to the common sense of the participants, exactly as postwork and imports (see next point). 4. Postwork and imports: as usual, I don't want to make an issue of this. Just keep both to a tolerable amount, I don't think there's any need to restrict this in the rules, we all showed common sense in the past challenges. 5. The trees created must be made available for the community at the end of the challenge, preferably in form of screenshots of the settings of the TreeLab. I think it's about all. If you're ok with it and AgentS and the Community approve them, these could be the official challenge rules. I just can't wait to learn from you :) S.
