Missing Reflection in HDRI About Truespace Archives These pages are a copy of the official truespace forums prior to their removal somewhere around 2011.

Missing Reflection in HDRI // Archive: Tech Forum 1  |   Order by default Post by MadMouse // Jul 8, 2006, 2:10am MadMouse Total Posts: 1069 Hi Guys, Just starting to get to grips with HDRI and have noticed a problem that I hope you can help with:- I was trying to render an object using HDRI for reflections only and normal lights for illumination. All was fine until I turned on mapped shadows on the lights and suddenly the HDRI reflections disappear:confused: I was using a Caligari Phong for the object and no matter how I alter the settings of the material or the lights or HDRI there is still no reflections other than from objects in the scene:confused: Turn off the mapped shadows or set them to Ray and the reflections come back. And now I'm stumped :mad: HELP!!! P.S. Oh if I use some of the other shaders i.e. mirror or glass then all is fine????? don't know if that helps??

If you set the Back.Intensity to zero then a regular background image or colour is used fo rreflections. Also see if you have Use Only Envir. Lights checked or not.

Lightworks MadMouse..it seems that is the case.in lightworks...caligari phong, enhanced phong, enviroment map, caligari metal..[didn't check them all,] but those don't seem to work with mapped shadows just raytraced ones.. vray doesn't seem to have this issue, mapped shadows seem to work.. Bummer.... Ok thanks Gord thats what I suspected:( Post by TomG // Jul 10, 2006, 4:51am TomG Total Posts: 3397 NOte that V-Ray doesn't support mapped shadows - your mapped shadow lights are rendered as raytrace shadow casting lights. This could be why the HDRI works in those cases. HTH! Tom Post by MadMouse // Jul 10, 2006, 8:16am MadMouse Total Posts: 1069 Thanks Tom :)
