Arnold Sher Posted June 6, 2006 Share Posted June 6, 2006 Hey guys and girls... Here is the issue at hand... We are doing a massive project(interior of an airport) that will be an animation. All is good and well.. Everything is modelled but now comes the fun part... We need to light this sucker... We've done some big projects in the past but the space is so massive the our trusted computers just go hmmmm...let me think about it...hmmmm: "NO!!!!!" The interior space is 250m wide by 750m long... Obviously the space is going to include furniture and whatever else is going to go with it... We would love to use vray but it is not handling it too well. We would love to hear from somebody who has done this kind of size of the project and the way of going about it in terms of lighting and keeping the rendering times down... Would hate going back to scanline as that rather feels outdated. Thank you all in advance and looking forward to hearing from you... Link to comment Share on other sites More sharing options...
manta Posted June 6, 2006 Share Posted June 6, 2006 Start using vray proxy meshes, what is this space, its huge ? Link to comment Share on other sites More sharing options...
Arnold Sher Posted June 6, 2006 Author Share Posted June 6, 2006 vray proxy meshes??? Excuse my ignorance, what's that???... and it's an interior of an airport.... Link to comment Share on other sites More sharing options...
manta Posted June 6, 2006 Share Posted June 6, 2006 vray proxy meshes are stand-in objects that are only present in the scene at render time, there will be and object in the scene in place of a high poly object or objects, so you could basically have thousands of high poly objects in your scene and it will run smoothly and render easily...

John Dollus Posted June 7, 2006 Share Posted June 7, 2006 Also, if it is like most airports, you will have a lot of natural light so use fewer artificial light sources. With large spaces, you can get away with using only a few lights. Link to comment Share on other sites More sharing options...
Justin Hunt Posted June 13, 2006 Share Posted June 13, 2006 Try the tried and tested method of 4 non shadow casting omnis above the model and 4 below the model. 1 distance light for the sun (raytraced shadows) and AO in the materials for the corner darkening effect and soft shadows. Then whatever specialized lighting inside as needed, try to keep the shadow casting lights to a minimum. Play with the attenuation and colour of the omnis to get desired results. It should render in no time at all and no worries about GI artifacts. Is the animation 1 long path? Try to break the model up into logical segments so that you can load and unload parts of the model that are needed as the camera passes. Obviously only put detail where detail is needed and use textures to add the detail in objects that are far away from the camera. The biggest space I have ever animated was 2Km of a shopping mall, with landscaping, walking people and moving cars. The shop fronts were fully modelled, but the interiors were just maps. The wole scene was around 3Million pollys and frames rendertimes were between 5 mins at best and 30 mins at worst. The animation was 2 mins total, broken down into 6 paths.

manta Posted June 13, 2006 Share Posted June 13, 2006 this should make things go alittle faster... http://www.spot3d.com/vray/help/VRayHelp150beta/tutorials_imap2.htm Link to comment Share on other sites More sharing options...
