Car cad data extreme slow down

[kosso_olli]

I think I might have an idea where ali's model is coming from... Is it that company from Munich, that has it's own "realtime" software?
I get data from them every week, and it is a pile of crap. Every part of geometry is child of a least 15 Helpers/Nulls. See attached screens. And the parts don't share these helpers, every part has it's own set of them!



I don't see the reason for that, but the parts are arranged into groups and nealy all of the helpers have names like "ANIM_ROT", ANIM_SCA", "ANI_TRANS". I can't understandwhy you need seperate helpers for all the transformations, for EVERY part. I mean, while working at Mackevision I learned how to set up datasets for creating configurators and such, but it was a completely different approach that worked very well in Max.

What I do nowadays is rearrange the parts into logical groups like headlights, seats etc. and delete all the unneccesary helpers. The scene is way more responive afterwards, but you are destroying the "logic" behind the clients scene.

Our data is very similar it seems but different manufacturer, not sure were it came from as it was delivered to us from the manufacturers creative department,
How are you getting this stuff working in max?
Going through manually and moving /deleting things seems very time consuming! And soul destroying lol

Our object tree, this is to get to one part its ridiculous,

I am looking at around 5000 meshes, and 20000 objects according to the summary window,

Now I realise this is a lot, but does anyone have any experience with dealing with a similar dataset, hardware wise ideally without editing the object tree,

Thanks

Hi Ali,

I think you can be fairly sure that has come from RTT, because the CSB files that are mentioned in some of the helpers are the native file format for their Deltagen software.
It's not just the German manufacturers that use them - From my experience, Jaguar, Land Rover and Toyota all do, and I'm sure there are plenty of others.

Anyway, I tend to deal with it by rebuilding the structure as layers in Max and getting rid of all the helpers. Takes a little while, but makes it easier to cope if they send you any new parts.

Cheers,

John

That is what I do, too. It takes some time to clean up the scene, but in my opinion it is worth it. Just so much nicer to have a scene that is way more responsive. Usually I end up with a scene consisting of around 20 different layers for exterior shots. For interiors, it is way more of course.

Thanks guys, really good info and good to know people are finding out ways to deal with the data,

Currently trying to find some kind of semi automated way to do it rather than manually digging through the scene explorer.

Also just opening the scene is consuming all 3gb of my video ram, so this may also be why it kills max, so may also have to invest in a card with more memory? Many thoughts?

[kosso_olli]

Check out the Schematic View for organizing these scenes. Most underrated tool in Max in my opinion, at least for the type of work I do. In combination with selection filters you can quickly rearrange all the objects.

Thanks Ill give it a look, something I've been wanting to get used to working with for a while now, but never got my head stuck into it

A quick update on this. We just got a new machine with an nvidia m6000 + 128gb of ram and although very expensive, it is really handling this data well. I can tumble around quickly with every single part turned on including all options for every part, plus 20 sets of wheels. Its extremely mind blowing, this should make digging through and organising this a lot easier,
Also it seems with this graphics card/ system Max doesn't crash nearly as much as it did before,

Oliver I would be very interested in learning more about your organisation workflow? Ive been using the schematic a little bit lately and it is fantastic for selecting objects etc,

Cheers

Interesting, but what is responsible for the speed gain? The M6000 or the 128gb ram? Probably both.

[ali_cgi]

Haven't a clue, i was think tumbling around etc would be the gpu, maybe moving geo the ram not too sure,
Maybe they all play off each other, but i think the 12gb of video ram definitely has a big role

Late question on this post but does anyone know how to remove the geometry from stacks of helpers like this without the geometry moving,
If i break the link the geo moves to its original transforms, and eve piece seems to have different transforms
Thanks Ali

Hi Ali,

Bizarrely, this happened to me today for the first time when I deleted some helpers.
I'm assuming you're on Max 2016, because I tried the same thing in 2015 straight afterwards, and it worked flawlessly, so I guess it's a bug.

Perhaps someone here that posts in the Autodesk forums could let them know so they can sort it out.

Cheers,

John

Yeh running 2016,
I break a link and things will flip out in 90 degree positions,
Strange for a bug, was thinking I had a settings wrong somewere yet too solve it! :/ love max bugs

[kosso_olli]

Interesting, never had that behaviour here in 2016. It is a stable release, didn't encounter any bugs yet.
