Get rid of the long hierarchies of modifiers. Vray more accurately calculates the shadows in places of fracture of grounds if these grounds belong to the same object, and all the vertices are weld.Ĭonvert all the geometry in the editable poly. As a result, it mixes colors (materials) of both (all) grounds with an unpredictable result.

Polygons must not overlap or coincide with each other, as Vray does not understand which of the polygons are considered basic and should be colored and which must be put on the background. There will also be dark spaces in the grid gaps (shadows). If the geometry is not closed, i.e., the net contains holes, Vray will take into account the internal space when calculating lighting, which will increase the rendering time. This result in following: do not use the standard “boolean” object, because after its application you receive many polygons-triangles with very sharp angle. Every extra polygon increases the file size of the scene, wastes the RAM and video card resources to its display, and requires more time to render the scene. Use the smallest possible number of polygons. Otherwise, you may face a number of challenges like undesirable artifacts in the final image. It is necessary to stick to some rules in the process of modeling in order that your rendering scene took less time and you received better results. Vray tips before you start to learn Vray 1.
