This is maybe not so much a specific VRAY question , but since I’m using VRAY as my renderer , I might as well post it here hope u dont mind
I got this very little and insignificant test scene setup. Trying to obtain realistic outdoor lighting on a sunny day somewhere in the south of France.
I got 1 Direct Target light hitting the scene from very far and rather high
Settings can be found on the screenshot
as you can see the shadows of the orange bar are completely off … they do not “drop” onto the right wall like they should … weird problem
(don’t look at the poor aa, all settings are low for testing purposes)
I think i know what is going on, and its quite simple.
The wall that you think should be recieving the shadows of the orange box looks like it is already in shadows or partially in shadow as there is no direct light hitting it. Try moving the light turner towards the camera, like swing it to the right more so that its pointing more towards the corner of those walls.
if he is trying to simulate correct sunlight (and correct shadows from sunlight) then he is right to use the direct light (from far away) so that he can get parallel rays hitting the model.
i have found, though, that if you place the direct light far away from your model - you can turn on ‘area shadows’ and still get the shadows to cast accurately on the model (using sunlight system to set location of the model, time of day, etc.).
