Crown version. In the settings Environment – Effects – Hair&Fur – Hair – geometry
The model is rendered very quickly and 500k hair is enough. Depending on the distance change the number of hairs. The model is more likely for long and medium angles.
There are two versions in the archive for mm and for cm.
The export file without wool contains settings in the archive.

On screen 7 I opened the scene and clicked render without maps and extras. settings the environment is white.
