Hi Clay,

When using the network rendering in Luxrender, it is Luxrender which takes care of transmitting all the required textures to the render slaves. If the textures work when doing a local Luxrender but not when using additional render slaves then the problem is in Luxrender, not the exporter.

Software: OS X 10.8 - Poser Pro 2012 SR2 - Luxrender 1.0RC3 - Pose2Lux
Hardware: iMac - 3.06 GHz Core2Duo - 12 GB RAM - ATI Radeon HD 4670 - 256 MB
