thanks...

oh... thanks a lot...

the true about the colours is that i didn`t know how to convert hex RGB code to RGB vector... i`m creating manually the materials and i put 10 0 0 to for the orange circle and 0 0 10 for the blue circle... and this is the result... but for me looks nice...

what about the light reflection from the right side? should i remove it in photoshop?

2000 samples/pixel are enough ?

rendering for 30 hours on my ath64 3000+... full size 1280-1024
what do you think? i should continue rendering? or it isn`t worthwile?

absorbtion?
hmm... yes... a grey background should be fine...

modeled in blender... rendered in indigo 8 ....

hmm.. why blender exporter is creating RGB colours with values <1 ? colour Sets the RGB reflectance (albedo). All components should be in the range [0, 1) Each component will be silently clamped to the range (after reverse gamma correction) [0, 0.9]. As of 0.7 test2, the RGB colour will be 'reverse ...

how can i convert a color from hex code (#ff00ff) to RGB vector?

if you create something transparent... the exporter export only the medium.... you should create manually the material in the igs file...
i prefere to create myself the materials in the exported file...

Page 36 in the example: <rectanglelight> <pos>0.0 0 1.9</pos> <width>0.2</width> <height>0.2</height> <spectrum> <peak> <peak_min>300</peak_min> <peak_width>550</peak_width> <base_value>0</base_value> <peak_value>200</peak_value> </peak> </spectrum> < efficiacy _scale> <power_drawn>100</power_drawn>...

tnx for the quick reply...
but how can i render textures?

SceneLoaderExcep: Rotation matrix must be orthogonal (In element 'rotation', around line 277, column 9)

the script have some errors at materials that have name with "." (e.g: Material.001). The script thinks that the Material and 001 are 2 materials blended... Another bug... dont know why...
