VRayPattern For Maya Manual

VRayPattern For Maya allows to multiply geometry periodically without extra memory consumption. As a sample you can use any tiled geometry (or those with unobtrusive joints). VRayPattern also allows to curve geometry on any surface. The plug-in works in similar way as displacement map. However, displacement map can only use raster or vector maps of pattern to cover the surface of geometry, VRayPattern can use any of the original geometry.

VrayPattern technology is fundamentally different from the technologies that are used in scattering. Scatters are multiplying individual objects, but pattern is actually a 3d procedural texture. The consequence of this is unique opportunity but lot of restrictions.

The unique features include: Possibility to literally not limit duplicating of elements. Automatic deformation of objects in accordance with the shape of the surface Low memory consumption when rendering.

Restrictions related to the possibility to randomise the elements, possibility to process edges and abilities to limit an area with other tools, except for the physical cut-offs of a surface. The same goes for the preview in the viewport - unfortunately there are no other possibilities to see anything in the viewport, but to generate and assign appropriate geometry texture;

The plug-in best used where large amount of geometry required, but without great accuracy.

Troubleshooting

License error

VRayPattern: Incorrect license!

If you were having Maya running while applying a license key, make sure to restart Maya after it.

In case of license malfunction and errors (which can be caused by disk reformatting, re-installation of the operating system or components replacement) you are free to address the developer at any time by sending your request for a new license key to mail@rendering.ru.

However, we reserve the right not to issue a new license in case of total replacement of a PC if the registration request is submitted more often than once in half a year.

Installation error

  • Make sure Maya is not running, please double check in task manager too.
  • Make sure you are installing with the administrator rights (on Windows 7 right click “Run as administrator”) .
  • Make sure you choose right installation path.

Other errors
