Help me to understand if that render is phisically correct

Hi everybody,
please, help me to understand if that render is phisically correct. I'm not sure about theese different diffuse stripes on the ground, like arrow shows on attached file. Materials are very basic, only diffuse and bump maps used. Light sources are made with a metal box closed by a glass surface, like in reality.
Thanks to all! Best regards

Um there is no problem with the reflection as the one you marked is actually the reflection of the statue on the left of the one you marked ;)

... looks odd to me. seems like the exponent of the floor material is changing ... ?

Hi cinema! I experienced a thing like this when using an old version of SkIndigo and Indigo, after having applied a png texture..

1. what version(s) are you using for rendering this scene?
2. is your floor texture a jpg? If not, convert any other format to obtain a jpg

like PureSpider, I don't see anything unusual, except for the weird glares on the floor lighting (too much, maybe?).

It may be that bug where a 1 component JPEG is used for the bump instead of a greyscale 3 component JPEG.

Thanks to all for reply.
I'm actually using the latest release of indigo and cindigo.
Yes, I used some png and some jpeg (<3 because of algorithm limit).
NO SkIndigo used, NO exponent is changing (I think)....only diffuse map with 1 color and 1 bump in grayscale.
I think that stripes limits are too sharp: light bounces should be much more diffuse and scattered.
Sorry for my bad english, thank for reply, best regards!

p.s.: I should continue this way to test indigo....I would like to help this community testing and improving benefits to indigo.
