Hide / Show Material Templates


It is possible to hide or show Material Templates both in the Shelf and the Material Ingest Tool to reduce clutter and complexity

Hiding of Material Templates can be achieved


    • By setting preferences in the Mari Preferences
    • By setting environment Variables



  • Setting visibility of Templates via preferences

You can control the visibility of preferences via the Material Templates Tab in the Mari Preferences (Edit Menu)



  • Setting visibility of Templates via Environment Variables

If you are working within a pipeline it might be beneficial to set visibility of templates globally for your whole team.


The following Environment Variables can be used to control the visibility of Templates


    • MARI_EP_MATERIAL_TEMPLATE_3DELIGHT
    • MARI_EP_MATERIAL_TEMPLATE_BRDF
    • MARI_EP_MATERIAL_TEMPLATE_PRINCIPLED
    • MARI_EP_MATERIAL_TEMPLATE_VRAY
    • MARI_EP_MATERIAL_TEMPLATE_ARNOLD
    • MARI_EP_MATERIAL_TEMPLATE_PIXARSURFACE
    • MARI_EP_MATERIAL_TEMPLATE_UNREALADVANCED


To hide or show a Template set the Environment Variable to TRUE or FALSE


 




As soon as one Environment Variable is defined, any non-defined ones will default to FALSE.


So for example if you just want to see the Arnold Presets you just need to define the relevant Arnold
