| Issue or limitation |
Workaround |
| The shader does not work with mental ray core version
prior to 3.3, this is due to a newer and required version
of the KD tree. |
Use 3.3 or later. |
| SDS (SubDivision Surfaces) are not supported yet |
Convert to polymeshes or NURBS. |
| Network parallelism is not supported yet. |
None. |
| Absorption and scattering coefficients may require 4 or
more digit numbers after the comma, some OEM UI's show only
3 digits in regular field numbers. However, extra digits
are interpreted correctly. |
None. |
| Objects should have an entering and exiting surface in
order to store photons correctly, open surfaces/meshes/sds
(when supported) may cause storage problems. |
Model with an eye on the storing process, think
volumetrically. |
