Ericoxer Posted September 9, 2007 Share Posted September 9, 2007 I'm fairly new to renderworks, coming from 3DS Max. I've got the basic idea, and for the most part i can make anything look equally good in both . . . except for lighting. Creating the light, and light quality arent really my issue, but i do know that in MAX i can tell light not to affect a certain object, or for an object not to receive light. I've had little success in RW. any help? thanks!! Quote Link to comment
Jim_Allen Posted September 10, 2007 Share Posted September 10, 2007 Eric, I still haven't had my second cup of coffee, but I think you can set objects to not emit and not reflect light. I don't have VW running, but it is in the OIP or edit item menu I believe. Quote Link to comment
Jim_Allen Posted September 10, 2007 Share Posted September 10, 2007 yep it is in the OIP - properties - render tab. Is that what you were looking for? Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted September 10, 2007 Vectorworks, Inc Employee Share Posted September 10, 2007 Hello Eric: You can't exclude objects from certain lights in RW. The Emit and Receive checkboxes Jim mentions are to force objects to participate or not in radiosity rendering mode. Quote Link to comment
Ericoxer Posted September 10, 2007 Author Share Posted September 10, 2007 ok, so its just in radiosity, not renderworks or (obviosly) open GL. Ok, i'll try that. That should get my focuses working better, and i assume this can used to keep the light from passing through the instrument itself . . .nasty nasty shadows. Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted September 10, 2007 Vectorworks, Inc Employee Share Posted September 10, 2007 Hello again Eric: The emit and receive options are to tell radiosity that the object re-emits light to its neighbors, or receives indirect lighting from its neighbors. They are not used to control shadowing or what lights affect the object. If you are trying to keep objects from casting shadows, create a texture resource and uncheck the "Cast Shadows" checkbox in the Edit Texture dialog. Then assign the texture to the object that should not cast shadows. The Spotlight instruments already have certain parts set to this kind of texture, to keep parts of the instrument visible but not casting shadows. HTH, Quote Link to comment
