Adjusting materials -- questions and suggestions
« on: August 29, 2015, 06:10:54 PM »
I find it tedious to adjust materials when I have a forestpack object with multiple types of geometry.  Below are a list of questions -- and if they don't have easy answers, then I would like to request improvements to make material handling faster and easier.

1. Is there a way to turn off the Forest Color Override feature in ALL materials for the selected object?  Sometimes I want to universally tint an object and I'd rather not dig through all the multi sub materials and turn off the Override switch.   

2. I would like a way to tint each type of geometry within a forest pack object individually.  This is possible now if you dig into the material editor and adjust all the Forest Color overrides manually -- but it can be time-consuming.  I would prefer if the main Forest Pack rollout had the option to do tinting globally (as it does now to all geometry -- AND also had the ability to tint each type of geometry individually.  It would be nice if the control was more centralized so digging through the individual sub-materials isn't necessary.  (This functionality would be much more useful if the idea in #1 was implemented as well).

1. No, unfortunately there is not any option to modify "Override" globally, but it can be done using Maxscript. The following script turns it off for the selected object:

Code: [Select]

fn FCProcessMaterial mat =
local i
if mat == undefined then
return 0
-- multi-material
for i = 1 to (getNumSubMtls mat) do
FCProcessMaterial (getSubMtl mat i)
-- simple material
for i = 1 to (getNumSubTexMaps mat) do
local tex = getSubTexMap mat i
if (tex != undefined) and (classof tex == Forest_Color) then
tex.override = false

fn FCTurnOffOverride fo =
if (classof fo != Forest_Pro) and (classof fo != Forest_Lite) then
return false
-- process all materials of the Geometry List
local i
for i = 1 to (fo.matlist.count) do
local mat = fo.matlist[i]
-- if material is empty, get material from custom object
if mat == undefined then
local cobj = fo.cobjlist[i]
if cobj != undefined then
mat = cobj.material
if mat != undefined then
FCprocessMaterial mat
-- update UI

FCTurnOffOverride $

2. This is more difficult to get. As you pointed out, now there are two modes to adjust tint: globally for the full Forest object, or locally by Material. This third option would need to replicate the tint options in the Geometry rollout (which is a bit complex actually). Or alternatively, some tool to modify the Forest Color settings for a specific geometry (assuming that materials are not shared by other geometries).
