i dont know what the blue in the standard glass material is? is it materials settings? is it rendering settings?

i have imported an obj file from blender, adjusted the materials and changed the glass material to Vue's (7 xStream) Standard glass.

Any ideas?

thanks in advance
chris

Well, the render is very small, but it could be the murkiness factor, try changing the 2 colours in the transparency settings , 1st colour all white, 2nd colour light blue, and keep the murkiness very low.

i tried another link and managed to get the image in here :D

i will try the murkiness thing (have not reached that area in the manual) and i have been experimenting with sub-ray options. that seems to help when i increase numbers there, but increases render time.

looks like it could be murkiness but the pic is so small I can't say

int he transparency tab, Murkiness sets the effect of oh, cloudy, dense materials, from dirty water, to gems or glass that's semi-opaque. Higher the value, more opaque it gets.

Also note, for many gemstones you MUST have that turned on, by the way as they aren't perfectly transparent. Many gems are indeed murky, especially when large or poor quality
:)

here I turn emerald, which isn't normally anything so storngly murky, way up, making a nice interesting material for crystal balls etc.

I had had simular blue sections and i solved it by increasing the  transparantie trace level . This can be done in the render options tab > User settings > check subrays > trace transperancy

By default VUE does look x many times true glass... increase that and you get better results (longer render time.

To test this:

Place a glass cube in front of camera, copy ith a few times behind it. At the third you will get blue sections, increase the trace level and you're ok again.

Sometime glass is picking up the overall sky color as well, so check that. Also, the greater the amount of refraction will cause the glass to shift to the sky color.

I'm afraid the image is too small for me to understand what's happening there. What do you consider wrong here exactly?


lightning2911 ( ) posted Wed, 28 January 2009 at 3:25 AM

i think i understand now  :D

if i want to be able to see through all the glass i need to increase the subrays number.

if i only want to change the color (when the max subrays number is reached) then i change the murky colour.

thanks for all the help

 Yes, when you see the blue, it means you didn't have enough subrays to effectively trace through the glass. Increasing it should do the trick.

Hm I had to increase Max Trace Level AND number of subrays :)
