hi awsjolie the sun never has passed the glass, you need trick with fallof , two values, i put the same value 0.5 and 0.5, the index is 1.52 for me, same of the glass
the opacity or change just the value 1 to 0.65 or 0.6 is like you wish pass the sun
how you did the wall and ceiling white ? i can't do it, can you share the setting ?
regards

To let the sun caustics generate passing through glass you have to put a value different to 0 in the caustic blur parameter for Pathtracing or PMC kernels

hi ttaberna i been put 0 in the caustic blur and the sun not passed the glass i think so have a trick to do it

Hi merid88
Try something like 0.003-0.01 you will see the light inside your room as render cleans up
Cheers

the first image is direct light and AO
second image is pathtracing with 6000 maxsamples and 8 maxdepth, saturation is visible
third image is camera values

merid, that "saturation" you see is not such saturation. That´s what we call Radiosity. It´s caused by the light hitting the ceiling after bouncing from the red wall. In AO mode, light bounces are not calculated (that´s why AO mode is so fast), while in diffuse mode, path tracing and pmc, you get radiosity calculation. That´s how it works a raytracing/pathtracing render engine, and also that´s how light works in real life.

add image using caustic blur 0.002, the same result, saturation in the view i don't know why
thak you ttaberna for the tip, maybe you can response why i have saturation in the interior ?
thank you for response paquito, but i'm desagree with you, in the real life you see the walls red or orange or blue, not see the the ceiling red or orange,
depend of the light source perhaps window or door or another point light, i remember in previous version that not was a problem, any way, i think so implement more things but have details to fixed like saturation
i think so is a problem like vray, saturation is a problem every day
regards

Take a look at this picture (that´s a real photograph, not CG)


Notice the orange tint in the floor. That´s the light hitting the floor after bouncing from the orange. It´s something physically correct.

becouse that color depend of the hour, angule of sun, camera, etc, etc
thank you for comment
cheers

That is not called Radiosity....it is called color bleeding and is present in real life.
Meri88 PM me with yur problem and I'll try to solve it.
Cheers

in 1.02 the shortcuts to open octane viewports (either from a toolbar or from the quad) dont work..testing in max 2013 64 bit...

btw

HAPPY NEW YEAR TO ALL .
