Re[2]: Creating reflective glass but not the usual way!

Hello Todd, sorry I read your mistake message after I wrote so using a mix2color node :)

no.. a mixer node.. not a mix2clr node

Hello Todd, so your saying make a texture in photoshop, use a mix2clr node and a transfer mode of screen?

PS- for everyone know one know my car issue?

ok.. can i ask  why can't it be done with the traditional methods? is there something else in your scene that is preventing it?  i still say you should just make a reflection "texture" in photoshop and maybe using screen.. mix it on top of a transparent object (again.. as a texture.. not a reflection) have you tried that? todd Christopher wrote:

Hello Todd, I'm after a car window reflection look but no matter where the car is it still has the appearance of reflections and glass to some extent.

he was suggesting to use them by themselves to understand what each one does do achieve its results... so you can try to recreate them in your own way... my problem is.. i still don't understand why you need to do what you're doing the WAY you're doing it...  but./.. i would change my methodology.. i would like to see examples of what you want that were achieved exactly like you want.. that is... show me a stillfrom a comic book or something like that where there is obviously no reflecting .. show me a drawing.. though.. once i see it... i be i will say.. take that and just texture your "glass" object exactly like that... stop thinking of it as glass if it isn't going to be glass....think of it as a textured object and texture it to look like whatever you want it to look like. does that make sense?? todd Christopher wrote: Hello Tim, I got a chromeshader and a good glass shader and I have them booth hooked up with a mix2color node but my outcome is nothing close to what i'm after ? Christopher Saturday, December 31, 2005, 1:43:10 PM, you w Hi Christopher,       see if you can find a material/shader on www.highend3d.com orwww.xsibase.com also check the samplematerials that come with the XSI install, see if you can find a good glassshader, a chromeshader and maybe something like a carpaintshader.      The glassshader is to get an idea about the amount of transparency and refractions required (to raytrace) a good looking glass(bottle).      The (environment mapped) chromeshader to get used to the look and feel of a good environment map. Take that as an example to google for more reflectionmaps.      The carpaintshader would be the extra mile, it´ll probably have at least one specular component, maybe even several layered ontop each other to give that *the impression of depth* you have when you stare at a highpriced, well-done car. Skip the paintflakes, you don´t need those, replace with the basic glass shader setup you´ve disected earlier    You should end up with a shadingnetwork that let´s you control pretty much everything - optimize down then:-)      Cheers and a happy new year!       tim      ----- Original Message ----- From: "Christopher"<walksfar(at)netscape.ca> To: "Tim Leydecker"<XSI(at)Softimage.COM> Sent: Saturday, December 31, 2005 7:06 PM Subject: Re[2]: Creating reflective glass but not the usual way!     This is exactly what i'm after, you couldn't go into a little bit more detail on how I could pull this off? And to Kim, yeah I know I have to spend a little more time in the rendertree I have been and I understand much more I know those two clr2slcr nodes were not needed i'll put the excuse on I was tired probably at that time :) Thank You all Christopher Saturday, December 31, 2005, 5:52:52 AM, you w Hi Christopher,        I guess you´re trying to get that distinct *white stripes across window* look, as in toons or carphotography but don´t want to have anything else (of the environment) appear reflected?      There´s at least two different ways, depending on wether the reflection should change depending on the cameraposition or not.       If the reflection is supposed to change depending on viewingangle you´d probably stick with an environment map, the more abstract the more stylish/stylized the result. You´d most likely get a good start by finding a chromeshader/tutorial that uses environment maps and just adding in transparency to that shader.    It´s most likely going to be some sort of a black/white gradient map, or something with a large portion of *sky* gradient in it, I guess.       If you map this environmenttexture using surfaceUV´s instead you obviously end up with a reflection independent of viewing angle.       The other way would be to use an extra light/pass on a material that´s all black exept for transparency and specular, maybe even having refractions and comping that ontop later.      Gives great control, adds *brilliance* and you can see the effect in the viewport. Also great for rimlights, backlights, filllights, tweaklights or whatever you´d like to call it. Usually adds quality and detail to a render.            cheers        tim             --- Unsubscribe?
