Hi first please excuse the the length of time to reply thank you for the material
this is what Im trying to do - no straight lines to hide discontinuities , I am unsure why the materiel works with your example but not with mine - I played with yours and the ground plane always stayed invisible even when sized to deliberately cut the shadow cast :) my ground plane is an sds surface to reflect the land shape Alasdair www.digitalmystic.co.uk ----- Original Message ----- From: Andrew Berge To: [email protected] Sent: Tuesday, December 05, 2006 8:49 PM Subject: Re: help with material Hi, If I understand u correctly then this is the shader u need. rgds, Andrew alasdair wrote: above there is a surface for the tank to sit on and cast shadows on which are mingled with the background picture it is not evident at this size / resolution but the surface is apparent on the backgroud pic to get this I played with lighting levels but have since forgotten / lost the setting :( I need a material which only displays if hit by light rays which do not recieved light directly any light Alasdair ----- Original Message ----- From: Neil Cooke To: [email protected] Sent: Tuesday, December 05, 2006 7:12 PM Subject: Re: help with material Hi Alasdair, >a surface where it is directly lit by a light to be invisible but otherwise normally visible This seems to me to be a time thing where the object(s) become visible when the light is on and becomes invisible when the light is off. If that is the case then animate the Fade material (materials library/Constant/Fade) to coincide with the light. If the light is to shine on only that object and no others then use the Light Sensitivity material. But there are a ton of other things you might be referring to so maybe I'm completely off target.
