pj1138 Posted January 26, 2004 Share Posted January 26, 2004 Hi, Is it possible to use HDRI based images with Houdini 6 and if so how. I have had one attempt using a light probe image from Paul Debevecs website. Houdini has to convert the hdr format into a .rat file in order for the Vex Global illumination node to use it as a light shader, I have had some interesting effects but not the same as Mr Debevecs work. Has any one tried this before with either a homemade hdr or one from the web. I Quote Link to comment Share on other sites More sharing options...
stevenong Posted January 27, 2004 Share Posted January 27, 2004 Hi there, If you click on the "?" button at the top right corner of the Houdini window, the Houdini browser will open. Next, click on the "User Guide Contents" & click on "Environmental Illumination" under Lighting. It is a tutorial on how to set up "Ambient Occlusion" & also Image Based Lighting (IBL). Cheers! steven Quote Link to comment Share on other sites More sharing options...
mark Posted January 29, 2004 Share Posted January 29, 2004 definitely try the irradiance caching, you can get rough renders that arent much slower than a normal render Quote Link to comment Share on other sites More sharing options...
