hi again, I question - direct render
.................
at extreme low altitudes weird light he casts a shadow while small source needs to be more brighter than big = = = he himself and leads to a higher height from the floor, but when I bring it to the floor there is a strange shadow - whether all true or is it a mistake ?

Hi Goldisart,
is absolutely obvious, it is shadow cast by light No. 2, if you do not want to see it, put not "visible" to check.

and I'm not talking about the object and two light sources . . . how light can form shadow ? from yourself ? if it is brighter than the main light source ?

I think it will be a wrong calculation algorithm or it is simplified for speed of render and therefore a shadow
....
or is it a mistake ray trace ...

Hi Goldisart,
There are different issues,
if you're using DL-AO your render is correct, you do not have GI.
other issue I think there is something around unit of scale.
My testing seems to work well,
attached the test.
Let me know about.

dear programmers . . . . repeat a million times !!!! the majority of people who work professionally with 3D max do not use the meter the world .... at work ... I use cm and mm .... please .... understand what is the problem and you personally, I suggest before writing the solution - see submitted 3d scene !!!! //// I finally realized what the problem .... dear developers write script dynamics the calculation of the ray Epsilon for different worlds m cm mm inch ... that's because its a static value there are all these problems
....
unit world m = 0.0001 ( 3- 000)
unit world cм = 0,00001 ( 4 - 00000)
unit world mm = 0.00001 ( 5 - 000000)
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

paride4331 - I very much wonder how you work with the meter unit !!!! I would imagine compartment hand or would have gone crazy working in this dimension
