[Closed] get maps aplied to modifiers

you can make your own list of modifier classes which for sure can’t contain any texture in its properties. all other classes should be checked.

OK, that’s a good idea.

res = #()
for m in join modifier.classes SpacewarpModifier.classes do (
	
	try (
	local a = m()
	) catch ( continue )
	for p in getpropnames a where classof (getproperty a p) == UndefinedClass or hasproperty a #maps do appendifunique res m
		
)

This probably can help you a bit. There’re some false-positives in resulting array
Do you guys aware of any other ways of detecting mapbutton of modifier?

enumeratefiles for a specified taget modifier has to work very fast. i think that you lose speed on anything else.

here is 100,000 volume_select modifier tests:

(
	txmaps = #()
	fn addmap map = 
	(
		appendifunique maps txmaps
	)
	m = volumeselect()
	(
		t = timestamp()
		for k=1 to 100000 do enumeratefiles m addmap
		timestamp() - t
	)
)

The scene that I use is heavy, and except this it is located on a slow Hdd on LAN, and most files are found. Found files on LAN is the most awful thing I noticed for max. It takes a lot of time even to refresh asset tracking, however I’m not doing it – just the function itself.

you are trying to not search in instances. which is correct generally. but maybe file enumeration is faster than finding instances.

In my first post I tested the same scene without excluding instances:

enumeratefiles <modifier>:23322ms ram:7120L

With excluding them I get all the files in less then 2 seconds.
23 seconds vs 2.

Except this, I’ve noticed that inside bgworker, when multhithreading, if I use getinstances, then I get unknown error, I spent 3 hours to understand what was the reason till I got to that conclusion. That’s why I do this operation outside of bgworker. Now I get no errors

how many modifiers do you have in the scene?
just simply:

(
    num = 0
    for node in objects do num += node.modifiers.count
    num
)

how long does this take:

(
	global txmaps = #()
	fn addmap map = 
	(
		append maps txmaps
	)
	m = volumeselect()
	(
		t = timestamp()
		for obj in objects do for m in obj.modifiers do enumeratefiles m addmap
		timestamp() - t
	)
)

it’s left from another code. you don’t need.

do your scene have a lot of materials which are used in a modifiers?
