Cindigo: A few material and sun light questions
Cindigo: A few material and sun light questions
Q1:
I try to let the sun come in trough the windows, the result you see in picture "no_shadow_if_glassmaterial_and_glassgeometry_on.png" but thats not what I want.
I want to let the sun come in an making those hard shadows like you can see in the picture "shadows_if_no_glassmaterial_and_no_glassgeometry.png".
But without removing the glassmaterial and glassgeometry !
And yes, the glass has a thickness
Q2:
I want to get a light blurry reflection on the floor material and some little bump. But I have no idea which parameters I have to change (the documentation has not enough information for me).
I also want to get a reflection on the glass material, which parameter is for reflection ?
Q3:
One more thing that I don't understand:
The angle of the sunlight in cinema is not the same as it is in indigo (compare "Shadows_in_Cinema.png" and "Other_shadow_angle.png").
So I hope didn't confuse you as more as I am already
Regards
Alain

I'm not sure.
I just saw that I can activate "export settings to xml" in the advanced register of the indigo render settings tag (i'm not sure if "export settings to xml" is set to false then indigo looks for the values in "inifile.txt" ??).
it was not activated before.
I can choose there render mode "MLT with BiDir" or "MLT Mode" or "Pathtracing with or without BiDir".
I just tried with "MLT Mode" and "pathtrace with BiDir" but it doesnt change at all. It just takes much more longer to render !

I'm testing the scene now Alain
interesting about the renessance.jpg bump map image it wanted..... must be some bug
damn a lot of objects. also your scene is too big! The autofocus was set at 420037.53196m according to the log file..... need to scale your scene down with the Cindigo cale settings upon export to be accurate, anyway I have hard shadows now..will post a pic soon
I used Bidirectional MLT
also the RGB absorbtion values in Cindigo of white RGB are too low to be of much use, since it doesn't have a scaling parameter unlike other exporters in other programs. Use the uniform parameter instead. RGB white = a value of 1

and for bump map on the floor. Have a bump in the C4D bump map channel for the floor as you already have, and then set the Bump size the Phong material to like 0.001, for a very slight bump, 0.01 a bit more etc
render after some more time, over 500+ samples now, you can see the details and reflections better now
and my settings. Max bounces set to 100 will render faster, 1000 will look better
make sure to select - save to IGI, so you can tone map the image later on with Violet or resume the render any time you want to with the Indigo Resumer program
