Tim Saunders Posted November 21, 2005 Share Posted November 21, 2005 sorry if i'm getting annoying, but i'm trying to get used to the upgrade from vray free to advanced. just as I was getting comfortable with my glass before i have to change in in order to be able to have the vray frame buffer split up my seperate channels for a render. aparently you need to use vray materials in order to have all the chanels split. with the vraymtl i did some tutorials on glass in the basic parameters. those tips worked great for glass that has curves so you can see some cool refraction effects, but 99.9999% of my glass is in a flat pane and don't need to see those effects. i tried using the same glass settings in the tutorials for architectural glass, but i didn't get the reflection i was looking for. i'm all for fresnal reflections, but to me just checking the box does not give you the right reflection. what i did with standard materials was load falloff in the reflection slot, then in falloff i loaded vraymap in the bottom slot. this gave that fresnel effect. however i felt like i was not getting enough (or any) reflection in the more straight on angles. even though that is the point of fresnel, there still should be some reflection in bright daylight. so i took that same method and made a mix of that fallof and a straight vraymap. then in the mix parameters i would increase the mix amount to maybe 20. this gave a slight reflection in those more direct angles. the first image is what i get when using the same method with a vray material, the second is with a standard material. any thoughts?

alfienoakes Posted November 22, 2005 Share Posted November 22, 2005 Tim, I may be way off here, but the trick to using that fall off map, is to not accept the black / white shades that they give you as the mix of the front:side reflections. If you change the black to a grey, then you will get some front on reflections, other wise the black, front on views will not show any reflections. I think thats what your getting at ..??

Tim Saunders Posted November 22, 2005 Author Share Posted November 22, 2005 that's totally what i'm getting at. i'll give that a try. i never tried adjusting the actual color swatches in the falloff params. Link to comment Share on other sites More sharing options...

alfienoakes Posted November 23, 2005 Share Posted November 23, 2005 Geoff.. Will these work with VRAY free? Andy Link to comment Share on other sites More sharing options...
Jeff Mottle Posted November 23, 2005 Share Posted November 23, 2005 Geoff.. Will these work with VRAY free? Andy No they won't, sorry. Here are the official requirements: V-Ray Architectural Materials Volume 1 is designed to be installed with Autodesk VIZ 2005 and/or 3ds max 6 or later. Currently Autodesk VIZ 2006 is not supported. V-Ray version 1.47.03 or later is required. These materials are version 1.50 ready. Link to comment Share on other sites More sharing options...

Inhibitor Posted December 27, 2009 Share Posted December 27, 2009 Hi everybody, it's my first post here and sorry for my bad english. I also have got a problem with my glass. I took the "perfect architectural glass" from vray-materials (I'm sure, you know that page). Unfortunately the reflections are too strong. I read some tutorials, and did some changes, but I still can't fix it. There is a map used for reflections with (front: side) and black and withe turned up to 100%. Changing it does not help. I just deleted the map and it of course works by editing the grey colour in the upper menu. But I'd still like to know how to fix it in the (front:side)-menu... Best regards, Edward Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted December 27, 2009 Share Posted December 27, 2009 This mat is using a falloff map for reflection? Don't see why it would need that. Simply choose black for diffuse color, set reflection to 100% white with fresnel on and refraction just as strong. That's it. You should also ckeck the affect alpha/shadows options and put the refraction exit color some green (so uou have green, natural looking glass borders).

Inhibitor Posted December 28, 2009 Share Posted December 28, 2009 Ah, ok! Thank you very much. That's what I have done - deleting the fall off map and using the basic reflection option. I will try that refraction colour. Thank you very much again! Link to comment Share on other sites More sharing options...
