====================================================================== ************************************************************ *Product Name: Human Nature - IBL Lightsets *Copyright 12.05.2008 *By: SaintFox and Digital-Lion *Contact: saintfox(at)web.de Please replace the (at) with an @ when sending an email. ************************************************************ Thank you for choosing Human Nature, a light set created for Poser 6 or higher! This package is a well balanced collection usable for indoor and outdoor scenes with a close look on how the lights work with skin to give you the perfect tool for realistic and lifelike renders. -------------------------------------- System Requirements: Poser 6 and higher -------------------------------------- Ownership Statement: All of the content in this package was created by Digital-Lion and SaintFox, and may include derivatives of the following merchant resources: Photgraphs by cgtextures Our own rendered images -------------------------------------- Installation Instructions: Run Winzip or another zip-program and point it your Poser directory. All files will be placed as shown below from the filelist. Be sure to check the "Use folder names" option when unzipping and point Winzip to your Poser directory. After unzipping you will find the lights in the folder "SF HumanNatureIBL" in your light-library. The folder containing the lights may be moved to another folder in the corresponding library if desired. The textures and geometries should stay as is, otherwise you will get an error when loading the lights. -------------------------------------- Usage Tips or Limitations: This package is made and tested to be used in Poser6, 7 and PoserPro with the Firefly Renderer. THE MOST IMPORTANT THING: Be sure to delete all lights from your scene before you add one of the light sets. Repeat this each time you want to change the lighting! We have included a handy button in the light-folder ("!DeleteAllLights") that calls the standard Poser python script to delete all lights from your scene. Using the lights is pretty easy. Build up your scene and choose the desired light. You'll see that you have the choice between "AO" and "NonAO" lights - each IBL based light comes in two versions, with and without Ambient Occlusion enabled at the IBL. If you explore the lights you'll find that each set is made from one IBL-light and one or more "assisting lights" that use colors from the light probe to emphasize the effect. You can change the colors of the assisting lights to your need and taste but we recommend to stay in the same tone or use neutral grays, otherwise you may destroy the overall effect. If you create something beautiful when playing with the lights: Be sure to save the result to your runtime!! This package is a well balanced collection usable for indoor and outdoor scenes with a close look on how the lights work with skin. We encourage you to play around with the camera and turn your figure(s) and prop(s) to catch different parts and sources of the set. Of course you can move and rotate the lights as well but as the assisting lights are placed to boost the effect of the IBL you may achieve better effects when moving and rotating the camera and parts of your scene. ******************************************************************************************* Some important hints about the interplay of textures and light: Please keep in mind that Image based lighting is a technique that came with Poser 6. The realistic effects that IBL can give you depends highly on the advanced material options that the newer versions of Poser offer you for your scenes. If you find your character looking dull or lifeless or if the skin-texture appears very dark we recommend checking the material settings of your figure. Image based light looks best on characters with advanced shader settings. Your character's material settings should contain shaders that add a slight shine to the skin: A blinn-node or a specular node or -map, even better when used together with bump and/or displacement. If you want to use a character that comes with a plain texture you can add a blinn node manually to all material zones that contain a skin-texture or use one of the tools that face_off offers (Unimesh realism kit, real skin shader, V4 realism kit). If you want to set up some sheen manually you can do it in the material room (advanced mode) and finding the first material zone of your figure that contains skin. Now click on the little plug beside "Alternate Specular" and choose New node-->Lighting-->Specular-->Blinn. Repeat this for every material zone that contains skin. If you desire it you can use the blinn node on the nails, too. The blinn node does not cause a glossy effect, the sheen just gives the illusion of healthy skin. The same may go with clothes, every piece of clothing that uses advanced material settings for the surface will look realistic when used with IBL while plain textures may (!) look dull and lifeless. Some words about Ambient Occlusion: Ambient Occlusion, called AO, can be described as an alternate kind of shadow. AO causes the small shadows that appear where surfaces come close together: The edge of a piece of clothing, the interaction of furniture and body, the region where the upperlip touches the lower lip - these things cause small shadows where the surfaces "meet". AO can boost realism and the feeling of depth in your images. You find that each of the lightsets comes in two versions: With AO added to the lightsource called "IBL" and without AO. So it's up to you if you want AO for your whole scene (choose the "AO" version of the desired light) or without (choose the "No AO" version). Often it is enough to set up AO for the character(s) in your scene and leave clothes, accessories and environment as is because Ambient Occlusion, added to the IBL, can increase the render time. But you should give it a try anyway, the effect may boost your render dramatically. If your character is already equipped with AO nodes you should make a test with both versions of the light and decide for the set that meets your taste. Often you get far too hard shadows with AO on the skin and the light! If the materials of your character do not contain AO you can use the "Occlusion Master" by face_off to set it up automatically or set it up manually. If you want to set up Ambient Occlusion manually you can do it in the material room (advanced mode) by finding the first material zone of your figure that contains skin. Now find the button on the right side (under the "Wacros" menu) that says "Set Up Ambient Occlusion". Click it once and you're done. Repeat this for all zones that contain skin but skip the nails, lashes and so on. Now you should render a small test with both versions of the desired lightset and choose the version you like best. If so called artifacts appear in your renders you can alter the value of the Ambient Occlusion in the properties of the IBL. We set AO to an avaerage value of 0.7 for all IBL-sets that have AO enabled. To get rid of artifacts try lowering the value in small steps and do some test-renders. ******************************************************************************************** -------------------------------------- Files Included in the Product: \Runtime\Textures\!SaintFox\HumanNature\ ballpastell1.jpg ballpastell1b.jpg ballpastell2.jpg ballpastell3.jpg ballpastell3b.jpg ballpastell4.jpg ballpastell5.jpg geometries1d.jpg landscape1round.jpg sky1.jpg sky2.jpg sky3.jpg sky3b.jpg sky4.jpg \Runtime\SF_HumanNatureIBL docs\ Readme.txt license.txt \Runtime\Libraries\Light\SF HumanNatureIBL\ !DeleteAllLights.lt2 !DeleteAllLights.png IBL Set 01 AO.lt2 IBL Set 01 AO.png IBL Set 01 NoAO.lt2 IBL Set 01 NoAO.png IBL Set 02 AO.lt2 IBL Set 02 AO.png IBL Set 02 NoAO.lt2 IBL Set 02 NoAO.png IBL Set 03 AO.lt2 IBL Set 03 AO.png IBL Set 03 NoAO.lt2 IBL Set 03 NoAO.png IBL Set 04 AO.lt2 IBL Set 04 AO.png IBL Set 04 NoAO.lt2 IBL Set 04 NoAO.png IBL Set 05 AO.lt2 IBL Set 05 AO.png IBL Set 05 NoAO.lt2 IBL Set 05 NoAO.png IBL Set 06 AO.lt2 IBL Set 06 AO.png IBL Set 06 NoAO.lt2 IBL Set 06 NoAO.png IBL Set 07 AO.lt2 IBL Set 07 AO.png IBL Set 07 NoAO.lt2 IBL Set 07 NoAO.png IBL Set 08 AO.lt2 IBL Set 08 AO.png IBL Set 08 NoAO.lt2 IBL Set 08 NoAO.png IBL Set 09 AO.lt2 IBL Set 09 AO.png IBL Set 09 NoAO.lt2 IBL Set 09 NoAO.png IBL Set 10 AO.lt2 IBL Set 10 AO.png IBL Set 10 NoAO.lt2 IBL Set 10 NoAO.png IBL Set 11 AO.lt2 IBL Set 11 AO.png IBL Set 11 NoAO.lt2 IBL Set 11 NoAO.png IBL Set 12 AO.lt2 IBL Set 12 AO.png IBL Set 12 NoAO.lt2 IBL Set 12 NoAO.png IBL Set 13 AO.lt2 IBL Set 13 AO.png IBL Set 13 NoAO.lt2 IBL Set 13 NoAO.png IBL Set 14 AO.lt2 IBL Set 14 AO.png IBL Set 14 NoAO.lt2 IBL Set 14 NoAO.png IBL Set 15 AO.lt2 IBL Set 15 AO.png IBL Set 15 NoAO.lt2 IBL Set 15 NoAO.png IBL Set 16 AO.lt2 IBL Set 16 AO.png IBL Set 16 NoAO.lt2 IBL Set 16 NoAO.png IBL Set 17 AO.lt2 IBL Set 17 AO.png IBL Set 17 NoAO.lt2 IBL Set 17 NoAO.png IBL Set 18 AO.lt2 IBL Set 18 AO.png IBL Set 18 NoAO.lt2 IBL Set 18 NoAO.png IBL Set 19 AO.lt2 IBL Set 19 AO.png IBL Set 19 NoAO.lt2 IBL Set 19 NoAO.png IBL Set 20 AO.lt2 IBL Set 20 AO.png IBL Set 20 NoAO.lt2 IBL Set 20 NoAO.png IBL Set 21 AO.lt2 IBL Set 21 AO.png IBL Set 21 NoAO.lt2 IBL Set 21 NoAO.png IBL Set 22 AO.lt2 IBL Set 22 AO.png IBL Set 22 NoAO.lt2 IBL Set 22 NoAO.png IBL Set 23 AO.lt2 IBL Set 23 AO.png IBL Set 23 NoAO.lt2 IBL Set 23 NoAO.png IBL Set 24 AO.lt2 IBL Set 24 AO.png IBL Set 24 NoAO.lt2 IBL Set 24 NoAO.png IBL Set 25 AO.lt2 IBL Set 25 AO.png IBL Set 25 NoAO.lt2 IBL Set 25 NoAO.png IBL Set 26 AO.lt2 IBL Set 26 AO.png IBL Set 26 NoAO.lt2 IBL Set 26 NoAO.png -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- USEAGE RESTRICTIONS -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- As per enclosed Renderosity MarketPlace Licence
