Need some helps for shadows on rendered pictures

[Matt]

The lighting issues are caused by one or two things.

1. GI cache may be slightly different between each render, and this can be solved by using GI caches files:

2. It could also be that the geometry of the shadows is being optimized too heavily for each view, in which case you can solve this by going to the Advanced tab on the renderer, and changing "Ray detail region" to "360 degree detail (optimal)" or "360 degree detail (highest)"

Would 0 cache work like what is seen in that tutorial? Im actually unsure why he did that. I guess speed?

Cache file is probably help self the spot lighting issue between renders.

First i would like to thx you a LOT for this  It was close to exactly what i was looking for ^^

Then let's be honnest, the result is more enought for what i need to do as you can see, no more shadow bugs and everything fit well 


But like i'm someone a bit curious i'd like to know why with this solution some objects are disapearing ? I mean, i don't see my grass anymore and for the trees behind as you can see some are INSIDE the ground ^^ and less than when i do a normal render :x
Like i said if you don't have any idea it's pretty fine for me, the result is really close to what i wanted ^^
But if i can understand a bit more this software it's always good to take

Did you make a cache file before populating the grass and stuff?

[Azerious]

Nop, populating everything THEN make a cache file ^^

[WAS]

Oh. Hmm. And they aren't set to hold out or invisible or something?

[Azerious]

No, and i can see it on the "models" view before render : 

[WAS]

I am honestly not sure. There is nothing else you did besides creating a cache file?

[Azerious]

Nothing, i open my project, populate everything, then i made a first cache file with the render on spherical camera, then render again my cams one by one with the cache file i just took before.
