Arnold attributes 3DS MAX

[madsd]

This thread is a collected effort from users to dust up attributes that can be called via USER_DATA nodes in shading - for 3DS MAX.


mtlID - Material ID index
uv_1 - UV channel 1, prefix channel number with "uv_"
paLife - Pflow Particles Life
wireColor - transfers a mesh's wire color to shading directly
root_colors - Hair&Fur, pr. strand color based on a control map
gBufID - The Object ID, assigned in the legacy Object Properties

If you find, or have knowledge about attributes and how to enable them, make a post in this thread and I will update the main post so the list grows over time.

Shouldn't this be in the MAXtoA docs???

Some of it is, but it's scattered.
Let us know if you have some more and I will add to the list.

It needs to be documented here:

very useful. The official doc is still not organized properly.
