Sun or camera shadow on grass | Тень от солнца или от камеры на траве

[hintuc_de]

На траве отображаются непонятные два прямоугольника, тени.

Их положение меняется когда меняется положение камеры или солнца.

 

Translate:

On the grass appear incomprehensible to the two rectangles, shadows.

Their positions changed when the camera or the sun positions had changed.

These are shadows from grass blades. Rectangles mark the end of your shadow casting distance (it is common for all objects in the world). So you can do one of the following:

1. Disable shadow casting by the grass. Go to Nodes settings -> Surfaces tab and uncheck shadows options: Cast shadows and Cast world shadows boxes. You will also get performance boost in this case.
   
2. Increase the shadow casting distance (which is BAD from performance point of view). Go to Render settings -> Comman tab and set Shadow distance to be further.
   

You can also read the detailed info on how shadows from world light sources are rendered in the following article.
