First, I work on Windows XP SP2, lux 0.5 (11.07.08) and luxmaya
You can see the relative WIP here : viewtopic.php?f=14&t=968
My background (circles) use a texture with tile (x8 in U and V)
But the result is not the same using Maya software or Luxrender
On the left : Lux. On the Right : Maya
With Maya, I see the repetition
It seems not working with Lux
So, can you tell me where is the problem?
