thejobe Posted August 8, 2006 Share Posted August 8, 2006 i was doing some tests with the IBL and wanted to see what i would get with glass objects Quote Link to comment Share on other sites More sharing options...
Korken Posted August 8, 2006 Share Posted August 8, 2006 Hi! Nice start, but there can be some improvemnts. It seems like there is low transparency, crank it up abit and use Index of Refraction with that and you can get awsome glass. This is one I made, but is isn't finished yet but you can compare to atleast. //Emil Sweden [attachmentid=19445] Quote Link to comment Share on other sites More sharing options...
thejobe Posted August 9, 2006 Author Share Posted August 9, 2006 made a few fixes Quote Link to comment Share on other sites More sharing options...
bentothemax Posted August 9, 2006 Share Posted August 9, 2006 It looks good for a start. The glass seems to dark though, more like a tinted windsheild, than clear glass. What are your settings? Quote Link to comment Share on other sites More sharing options...
Korken Posted August 9, 2006 Share Posted August 9, 2006 If you want, then you can try to set tansparency to >95% then you will get clear glass. But to be sure, please post your settings. //Emil Sweden Quote Link to comment Share on other sites More sharing options...
MattWBradbury Posted August 9, 2006 Share Posted August 9, 2006 That tinted glass can be caused by two things. You may have too high of an index of refraction, and your Ambiance Occlusion could be making the area too dark underneath and arround the glass. My suggestion would be to make your glass models not cast Occlusion because glass wouldn't create that dark of a shadow (AO doesn't simulate transparencies); your glass looks like it has a fair ammount of tinting on it. Glass does cast some shadows, so you can add a light to give you some lighter shadows. Looking good! Now just add some bunsen burners, and you'll be set.

thejobe Posted August 10, 2006 Author Share Posted August 10, 2006 ok settings are as following all glass objects color: white falloff: 120% spec color: white spec size: 50% spec int: 80% transparancy: 95% refraction: 1.5 transluncy: 96% reflectivty: 35 camera settings multipass: on 16 passes AO: on sampling 70% choreograhpy settings: IBL lighting: AI: 21% AO: 70% map: HDR mirror shpere exposure: 2 azimuth: 50 those are the settings i used render time was 22 mins Quote Link to comment Share on other sites More sharing options...
Korken Posted August 10, 2006 Share Posted August 10, 2006 One thing I see is that Index of Refraction is way to high. If I'm not misstaken then 1.1-1.15 is often recomended but i used 1.07 in my glass. This is going to look god when it's done just don't give up. //Emil Sweden Quote Link to comment Share on other sites More sharing options...
thejobe Posted August 10, 2006 Author Share Posted August 10, 2006 ok made alot of changes to the glass to make it more transparant tell me what you think Quote Link to comment Share on other sites More sharing options...
dude Posted August 11, 2006 Share Posted August 11, 2006 Much Better! Looks great -dude Quote Link to comment Share on other sites More sharing options...

aaver Posted August 11, 2006 Share Posted August 11, 2006 [...]If I'm not misstaken then 1.1-1.15 is often recomended but i used 1.07 in my glass.I don't know where you've got that information, but 1.07 is way too low. 1.5 is a good for ordinary glass.

thejobe Posted August 11, 2006 Author Share Posted August 11, 2006 actually for this render i used just 1 for refraction 1.5 was too high and so was 1.07 always seem to make it too dark but 1 just came out good enough heres the new specs i used all glass objects color: white falloff: 120% spec color: white spec size: 50% spec int: 80% transparancy: 70% refraction: 1 transluncy: 90% reflectivty: 35% camera settings multipass: on 16 passes AO: on sampling 70% choreograhpy settings: IBL lighting: AI: 21% AO: 70% map: HDR mirror shpere exposure: 2 azimuth: 50 some one tolded to bump up the spec on the glass to make it stand out more so im going to give that a try and see what shows up but im happy with these results Quote Link to comment Share on other sites More sharing options...
Korken Posted August 11, 2006 Share Posted August 11, 2006 I must say it looks great! But i still miss a little refraction. Maybe just try so set it REALY low, like 1.01? It might give you the right effect.

Drakkheim Posted August 11, 2006 Share Posted August 11, 2006 Well if you're shooting for real glass its somewhere between 1.45 and 1.8ish http://www.robinwood.com/Catalog/Technical...nIndexList.html Quote Link to comment Share on other sites More sharing options...
thejobe Posted August 11, 2006 Author Share Posted August 11, 2006 i added a bunsen burner and even 1.01 was making it too dark for some reason could be something with AO not sure but this gives it a good enough effect of glass Quote Link to comment Share on other sites More sharing options...
