All greetings I bring to your attention the designer of ventilation. The model is prepared for real-time rendering there are textures of high resolution 4096 * 4096
can be used for offline rendering in the interior or exterior.
the scan is performed in such a way that when the length of the cylindrical element is increased, the texture will be torn.
The pivots of the elements are arranged so that it is convenient to assemble the constructor.
