Transforming vertices

[patoaltaco]

Could be that this action takes much more time than V3?

Is there a way to improve it, i mean if i could do something for optimizing the file or something...

Cheers.

I have the same problem and already reported it (with a pretty big scene), but keymaster was not able to reproduce it on his machine. So if you have a "simple" scene or a specific material/object causing this problem it would be great :)

[patoaltaco]

Mine are large too...

[patoaltaco]

I think  i have found the problem at least in my files.
Is a window multi sub object with glass / metal / plastic.

If you want i can send you the material.

Cheers,

Sounds like a good find! If you can I'd also like to have a look on your material, maybe i can find some similarities in my scene (the problem is a real pain in the a**, 10 mins transforming vertices :-( )

[Edit] ok, killed all multimaterials in my scene but still the same problem :(

[patoaltaco]

I think is when you have an a multisub object material and the corona submaterials have a map on the difuse............

I will continue testing.....

[patoaltaco]

just for try can you aply a simple corono material to all the scene?

[racoonart]

Yes, when reassign a simple new corona mtl to all objects it's lightning fast, I should have mentioned it before, this could have speed-up your search, sorry.

[edit] oh and i tried to disable each single feature of all materials one by one (per script) but i couldn't find anything. No maps, no colors, no reflection, refraction, etc... The strange thing here is: it got faster and faster the more objects I was hiding - so, it's something about materials but... not only one specific ;)

[edit2] Btw, i also tested if it's something related to windows (I've got win8 here) - it is not... but maybe it's something related to the cpu generation or something (which could explain why keymaster is not able to reproduce it). Could you share some cpu specs?
mine: 2x E5540 Xeon cpus, other machine (with the same problem) 2x E5530 Xeon cpus

[patoaltaco]

i think is that type of material (multi) on objects that have intersected geometry. but not sure

core i7990x 24gb ram / w7

[racoonart]

Not here ;) Since I don't have any multimaterials anymore in my scene

it is probably something rotten inside 3dsmax, not CPU issue...

My actual workflow is to build all the shaders using Multi-Sub Materials. I like to have ALL materials of an object on the same tree. It´s good to make testes on the shading step and faster to exchange any material on the object.

    Right now i am doing an animation of a bit complex object with more than 27 different materials on the same object (a car). 27 Material IDs used on a multi all corona.

     The trasforming vertex part is becaming a issue. It´s like 2-3 minutes right now, but i am not sure the fault is the amount of Ids. It is ???

      Yesterday this render Crashed a few time during the Transforming stage. :( I don´t know why, but after turning of Motion Blur and Dof and close all the softwares but max the render goes ok.

      I am trying Corona on a production as a Fire test, but yesterday (with those crashes) was the first time i was afraid with my deadline. :) I don´t want to remake all my work on Mentalray (please not). lol.

I have this geomtry extracted of a big file i have like 350mb. With a simple corona material (white it have no problem) with a material with some tweaks and maps like difuse it takes long time transforming vertices.

Here I upload de file.

Cheers.

Couple of questions:
What 3dsmax version should I use?
How long does the transforming take?
What CPU do you have?
Is it supposed to take long when I render it exactly as it is saved?

[patoaltaco]

I will give exatly values tomorrow..

but....

max 2012
between 30s/60s on the file I upload with meterial aplied / without material (simple corona material withe) aplied = 0s
core I7990x 24gb ram
could be, but not shure on this.

Cheers,
