3D Studio Max 8

This script replaces the built-in light lister with one that incorporates support for VRay Lights and VRay Suns.

Called anytime the selection is changed the script shows in the prompt line (lower right corner, next to the listener ;) the dimensions (as integers) of the selected object in the current units.

Comes very handy while working with interior/exterior scenes. to me at least :)

The script takes existing UVW Elements and scales them relatively to
their proportions in the parent object.

Works only on a single poly or mesh object.

A set of tools to aid in the daily VRay work.

Updated for VRay 1.5 SP2.

Matrix-Weighted Exposimeter V. 1.19 : very similar in principle to that of dSLR, it allows for different weighting of each slice/square in which the image is divided, as well as allowing a different range of pixel brightnesses to be chosen for the exposure (akin to real world lens filters).
Entirely customisable for behaviour.Now with auto-white balance and preset manager!
From V. 1.16 it supports exposure / White Balance animation through the script.
Please note this is not meant to be a frame by frame tool: doing so will result in flickering (like for standard dSLRs) and will likey lead to max crashes due to maxscript memory heap overload.
Keep previews small, Nth frame at around 1 second, and go in and refine by hand activating "Auto Key" from the max interface and exposing the problematic areas.
UPDATE: The Sample Rate calculator, new with 1.19, is an early attempt at DMC AA optimisation.
It will render a sample pass with whatever DMC AA (ONLY!) settings you have, analise the sample rate, and guestimate a new threshold value (AA noise threshold only) so that the BIAS setting may be met (+- 2.5%).
The BIAS indicates the pixel brightness average in the sample pass (where ~0 is min sampling, and ~1 is max sampling).
