Hi Przemas, thanks very much for testing it!

I'm not sure right now what I can do about it... Is Nouveau not good enough to use instead of the proprietary driver?

Thanks, - Michael

@Michael - will try posting on Nvidia boards. Maybe someone will figure it out.
Nouveau is sadly not an option - I use a bunch of 3d apps where it would be a showstopper (Modo for example). In general because of Nvidia policy and trying to keep everything under their control open source drivers support for their cards is lacking (you simply have to use their proprietary driver if you need good 3d performance).
One of the reasons I won't get Nvidia card for the workstation that needs a replacement. But the one in my pc is too new for a swap. Maybe if I do a bit of juggling between PCs and keep Nvidia GPU only for a vm with pcie passthrough...
Anyways ... hope to get MoI running correctly on my Linux workstation - and I intend to keep on trying ;) .

Congrats Michael, this SubDs to NURBS is amazing addition to already great app like MOI.
Thanks.

Just to add my test, too :) Have to admit, this is just what I wanted, ability to convert to nurbs at some point, do trims and blends and export back
to polygonal modeling app. Through years, learned to avoid all edge weighting except full sharpness, where result is same as disconnecting. This was only way to have a predictable results anywhere.

Here something very interesting, made with blender cloth simulator and SubD into NUBRS, very clean result only edges on boundary of surfaces.

The sds mesh to nurbs conversion is a great idea, indeed! Thanks to Micheal for adding such a useful feature to Moi!

Btw, Anto... what tools did you use for producing such a mesh object? Mesh fusion, Hard mesh? Or the new add-on of Blender 'Bevel after boolean'?

It's an old experiment in Houdini, where everything is created by combining the parametricaly created elements, one frequent element is 'bubble' in pic (it starts from modified circle). Then there are interpolations in NurbS blend style between them, projections to mono-wing (also defined by arcs and blends) or these 'bubbles', so on. In Blender world this could be more in Sverchok category (at least I believe). IMHO, not really approach for meeting the deadlines, because in R'n'D style approach one has to take care about hundreds of additional parameters, conditions and such.
Regarding 'mesh cut and blend' approach, while this is possible mission (and btw I did one for Houdini), I wouldn't count that much on them, anywhere. There's immanent problem of highly subdivided mesh, needed to get the cuts smooth enough. For ratio between bounding box and detail, typical for plane or car, that's really, really unpleasant polygon count. While Nurbs easy can go in such challenge, surfaces are meshed just at the end of the day.

Thanks for the reply! : - )

I believe that you can ask something like that to the lovers of Elephant by Max Smirnov! ;)

Here are some steps to repeat a bug that I don't remember being in V3.

Open a 3DM file and select some curves.
Click the Export icon and notice that the 'File name:' box isn't filled in with the currently loaded file name.
From the list of files in the folder, choose the currently loaded file name.
Change the 'Save as type:' to DXF and click 'Save'.
A warning 'Confirm Save As' box appears stating "xxxxxxx.3dm already exists. Do you want to replace it?"
If you happen to click 'Yes', then your 3DM file is replaced with just the selected curves.

Hi Pilou,
Could you please explain the process you used to prepare the demo soldier as an obj for MoI SubD? How many polygons did you convert it to, and how?
Thank you!

<< explain the process

Hello

Very simple ;) (this object .OBJ is start quadrangulated)
Use the plugin integrated inside ZBrush call Decimation Master : so you can take any number of polygons as result.
1/10 is normally sufficient - 50 000 polys seams reasonnable
If you have not ZBrush take any free prog like MeshLab: http://www.meshlab.net
Menu Filters / Remeshing, Simplification & Reconstruction... for Decimation
menu Filters / Polygonal & Quadmesh... for Quadrangulation

I don't remember the exact number i will remake it so be patient 10 minutes! :)

32 544 polys as result : loading in 18 seconds inside MOI 3.0 (on my latop Windows 10 - I7 4 years old)
(I must verify if it's vertices, edges or faces because it just write number during the process inside moi! ;)
Verified : it's 32 544 polys! ;)

I will put here the file decimated !
So you can load it directly inside Moi with _importObj by Max Smirnov for make your own test! ;)

Bump: Just in case it's been overlooked:)

Hi Martin, sorry I haven't gotten to that one yet, but now with v4 MoI is using the dialog through Qt which should hopefully behave in a standard way.

I was wondering if that's intended behavior or not. I need to check out what other apps do to see if MoI v3 was not doing it as expected or if it's MoI v4.

The nudge keys are not working. Specifically, the arrow keys and the page up/down keys for moving the selected objects by the grid quantum. When I press the right arrow, for example, I get an alert that says:
SyntaxError: Expected an identifier but found 'Right' instead
line 1
1: >> Nudge Right

I imagine that these functions are implemented with a script, but even so why is this script failing?

Thanks for making v4! FYI, I've got a file with over 5K objects. V3.2 loads it in about 29.5 seconds. V4 loads it in about 3.2 seconds. Wonderful!

This can be used by a trial version ? Seems there is much jaggies for a big size ...

script: /* Print screen to Clipboard */ var prev_background = moi.view.viewportBackgroundColor; moi.view.viewportBackgroundColor = 0x000000; moi.view.lineWidth = 4; moi.grid.display = false; moi.grid.showXYAxes = false; moi.ui.getActiveViewport().renderToClipboard( 2560, 2560 ); moi.view.lineWidth = 1; moi.grid.display = true; moi.grid.showXYAxes = true; moi.view.viewportBackgroundColor = prev_background;

for beta V4
script: /* Print screen to Clipboard */ var prev_background = moi.view.viewportBackgroundColor; moi.view.viewportBackgroundColor = 0xFFFFFF; moi.view.lineWidth = 1; moi.grid.display = false; moi.grid.showXYAxes = false; moi.view.showAxisIcon = false; /*moi.view.meshAngle = 3;*/ moi.ui.getActiveViewport().renderToClipboard( 4000, 2500 ); moi.view.lineWidth = 1; moi.grid.display = true; moi.grid.showXYAxes = true; moi.view.showAxisIcon = true; /*moi.view.meshAngle = 8;*/ moi.view.viewportBackgroundColor = prev_background;

Hi Christopher, you'd get that kind of error if the Nudge script is not installed. For v3 you must have installed it at some point by copying it into v3's commands folder. You'd need to do the same for v4 to get it to work.

For v4 you can also install commands into a commands sub-folder inside MoI's user data folder, you can find your user data location by using Options > General > Edit .ini file button, a dialog will pop up and tell you where your moi.ini file is located at which will be in your user data folder.

Copy the Nudge.js file from your v3 commands folder into the user data commands folder and v4 will look for it there and you won't have to keep copying it into new versions anymore.

Hi Michael.

I quite like the way MoI V3 handles it as you can look through the list of files, select the name you want and then choose the type of file extension you want to save it as. It allows slow/lazy/forgetful typers like me to have indentical file names with multiple extensions with near zero effort.


Martin.

Michael, thanks so much for reminding me that I installed a script for this. (Sorry I forgot.) I copied it into the Application Support subfolder as you suggested and I have my nudge keys again. Yay!

You might want to change the code that looks for scripts to have it output something like, "Script ____ can't be found. Install scripts in Application Support." :-)
