Advice Needed for Asset Management Script


Also don’t count out a full fledged relational database as the back end.

I’m converting our big toolset right now to use MySQL. The entire scene can be reconstructed from the database and it’ll let you use all the existing relational data tools instead of coding them yourself.

If you’re going to go through all the trouble of creating an asset management system it might as well run outside of Max. I would try to do as much in a portable language as possible.

That all being said… what’s in that frame is quite simple. I would define a struct “Categorystruct (CategoryID, Name)”

Create an array of categories.

Createastruct called ItemStruct (ItemID, CategoryID, Name, Filepath, ThumbnailPath)

Create an array of items.

Populate the category drop down from the category strut.
dropdown.items = for o in categories collect

CategoryItemArray = for o in itemstruct where o.categoryid == dropdown.selection collect o

rolloutstring = “” as stringstream

format “rolloutdef = ALL THE ROLLOUT DEFINITION STUFF” to: rolloutstring

then something like

for o in CategoryItemArray do
format “%Button% blah blah blah bitmap:openbitmap % etc etc” o.itemid o.thumbnailpath to:rolloutstring

then something like

for o in CategoryItemArray do
format “on %button% pressed do mergemaxfile %” o.itemid o.filepath to:rolloutstring

format “END ROLLOUTSTUFF” to:rolloutstring

removesubrollout (existing subrollout)
execute rolloutstring
addsubrollout rollout rolloutdeffromstring


so nobody knows of any commercial plugin or script that does this?


Commercial eh? How much you willing to pay. :smiley: I’ll make a commercial script.


Hi thatoneguy.

You want to make a commercial script?? did you know the vrayscatter made by icube. this will be sale 100 euro. If you can make out this , how much do you think It’s fine to sale.


I don’t know what VRay Scatter does. I presume it’s more sophisticated than this. But this’ll merge in a file from a small asset library. Note you’ll need to create your own scene library following the included examples. Also note this will crash if you don’t have a C: est\etc



Ok. I added a button which parses a directory full of directories… which is full of scenes and thumbnails (100x100 pixels)

Or you can hard code in your libraries as before:

well done, thatoneguy~!!
that’s great, I think you can do it whole.



Just to be clear here is the directory structure it expects:

…\LibraryPath<Category Names>\filename.jpg&.max

just did a cursory glance abouts the internets and found no documentation for creating a Vray proxy. So if someone would be so kind as to find that I would tack it on.


I’ve been thinking about this for the exact same purpose. I thought a simple solution could be to use html (i.e. use a web page creation program) to create the directory tree with thumbnails etc and use i-drop links to drag and drop the max scenes (e.g. containing only a pre-textured vray proxy) into your current scene.

I’ll check out your script, thanks.


Our Cat browser uses a dynamically generated html page, via an activeX controller, to display the contents. This allows drop and drop as well as controls to add to a list of items to merge.

A tree view shows all available directories, minus ones that begin with “Z-”.

A simple partial string function, for “seaching”, sorts on the filenames during the generation of the html page.

Wish I could share it, but it’s not mine…


that loosk quite useful Kieth, if i may ask how are you generating the html? this is one of the couple projects that i’m looking at making in whatever spare time i can dig up also :wink: especially since the default max asset browser looks to be completely non-functional at the moment


The webpage was initially designed in dreamwaver then I copied the html in the script line by line as strings to use as a template. There is also a function that looks in the directories and based on the files existing there and with the help of the html template builds the webpage and saves it in a temp folder from where it gets read by the activex. So everytime you change the directory that page is rebuilt.

Some extra functionality that the script has is to enlarge the thumbnail to a full size render, you can open the curent folder in windows explorer and you can add items to a merge queue and import them all at once.

I hope it made sense, it’s been a while since I wrote that and as Keith was saying I wish I could share it but it was done while at Focus so they have all the rights for it…


i agree Gavin Greenwalt. any works should be pay in suitable .

im a max script developer for 3 years , used to work in Crystal CG shanghai for about 2 year .

in china , most animate studio using 3dsmax , and do not have a TD .

for this work , i can work it out in a month . but as for TD , i expect to serve a studio for long time , not just do one script tool when somebody needed . for simple script we can do for free , and for this one , we cant .


i suggest u hire a TD like Gavin Greenwalt , it will be a great help for ur work pipline . a good TD can be freelance guy .


Think I’m going to have to write my own one of these for our company, we could really do with one for browsing HDRs and models.


Hey Anton;
How’z out there in the freelance world?

Perhaps talk to Anton about him writing one of these for you, it’s a great tool and I’m sure he could make it even better the second time around, plus customize it to your file structures and workflow. He was here at focus360 for years and writes some nice code…


Hey Keith, freelance world is pretty good, cannot complain. As from the writing nice code all I can say is that I’ve learned from the master :bowdown:. Any plans for siggraph?

You are right, hiring a TD to help streamline the pipeline is one of the best moves a company can make if cannot afford to have one in house full time which is the proper thing to do!


Thanks for the shot of what you have, and the tip on the dynamic web page, seems to be a pretty valid way to do it.

If i may ask, how are you sending info on which thumbnail or button was clicked back to the maxscript from the web control?


Well, so far I’ve got my auto generation of the basic page (Fills an array of thumbnails into a table) based pretty heavily off of Gavin’s code above, I’ll post something about it when its a bit more stable after I get a few more minutes to toy with it.

I’ve also done a bit towards generating the thumbnails from our initial directory of props, using PEN’s BatchItMaxcombined with a couple scripts Description: here namely the Render Thumbnail script

now to figure out the rest of the UI :slight_smile: am I demented for enjoying figuring this junk out?


The activex control has an event called “NavigateComplete2” and I’m using it to send the path back to maxscript. To find all the events just querry your activex using “showevents”
