TomA Posted March 13, 2008 Share Posted March 13, 2008 Anyone know a good Vray mirror material? I've created one with these settings but i've got a hunch they're a little dodgy: Diffuse Raytrace map set at 100%, Reflection colour set to white, refraction to black, shader set to Phong, and that's about it. Know a better 1, or how i can change mine to make it better? Tar Link to comment Share on other sites More sharing options...
manta Posted March 13, 2008 Share Posted March 13, 2008 do not use raytrace maps with vray... Link to comment Share on other sites More sharing options...
TomA Posted March 13, 2008 Author Share Posted March 13, 2008 Had a feeling that was the case. Thanks. So can you recommend an alternative in relation to my mirror material? Link to comment Share on other sites More sharing options...
rivoli Posted March 13, 2008 Share Posted March 13, 2008 use a vray mat, set the reflect color to 255 white and that's it, a 100% reflective mirror. Link to comment Share on other sites More sharing options...
TomA Posted March 13, 2008 Author Share Posted March 13, 2008 Thanks. What about the shader, phong? Link to comment Share on other sites More sharing options...
BrianKitts Posted March 13, 2008 Share Posted March 13, 2008 default "blinn" works. As another note, I always make my mirrors with a diffuse color of black of course and only about 98% reflective, not 100%. It helps it to read, specifically in small rooms where the wall color behind the mirror is the same as the color of the wall in the reflection.

TomA Posted March 13, 2008 Author Share Posted March 13, 2008 excellent thanks i'll give it a go. Link to comment Share on other sites More sharing options...
rivoli Posted March 14, 2008 Share Posted March 14, 2008 well yes, mirrors don't reflect up to 100% the light they receive. you may even try enabling fresnel with a very high ior value, it may end up being more accurate than the totally reflective surface way.

qwinkan Posted February 19, 2009 Share Posted February 19, 2009 i am working on an interior scene of a gym, and there are mirrors everywhere, and they are reflected on each other in black. how do i fix that? thanks please help, it's for work and I will be in big trouble if i don't get this right my email: qwinkan@yahoo.com Link to comment Share on other sites More sharing options...
BrianKitts Posted February 19, 2009 Share Posted February 19, 2009 vray has a cutoff for two objects reflecting each other back and forth so that you don't force it into an infinate calculation of reflections. You can adjust the cutoff number in the global switches. Try increasing the max depth value. Link to comment Share on other sites More sharing options...
riccardomariano Posted June 25, 2012 Share Posted June 25, 2012 Hi everyone, I am trying to make a sun/light beam bouncing on a mirror and being reflected onto another surface in an interior scene. Does actually a mirror like material reflect lights? Is this possible on vray 1.5? here is an example of what i want: http://www.mr-cad.com/mrcad-blog/ref...caustics-9.jpg thanks Link to comment Share on other sites More sharing options...
5ran Posted June 28, 2012 Share Posted June 28, 2012 here is an example of what i want: http://www.mr-cad.com/mrcad-blog/ref...caustics-9.jpg thanks this effect is called reflective caustics (see the name of that picture you have posted :-) its quite tricky to tweak the settings - its based on the photon mapping in most cases see vray on-line help here http://www.spot3d.com/vray/help/150SP1/ for more info - its far to complex for this forum..

riccardomariano Posted June 28, 2012 Share Posted June 28, 2012 thank you very much, It actually worked with Vray for max using a spotlight.... but it does not with rhino and sunlight. I think it has to do also with the kind of light. In the end it's just a basic reflection... Link to comment Share on other sites More sharing options...
5ran Posted June 28, 2012 Share Posted June 28, 2012 i dont use rhino and i am not the caustics or photon mapping specialist, but as i remember.... if you are using sun, u have to watch the "photon emit radius" setting (its the radius of the tube gizmo around the sun object) - I hope its same in rhino... try to keep the radius as small as posible - smaller radius means less photons = less memory, time etc. your mirror should be inside the green tube gizmo representing this setting (photons are not emitted outside the gizmo) Link to comment Share on other sites More sharing options...
