/ Grease Pencil Add-ons for Animation (Blender)

Jorge Vidal

Here you can find some interesting add ons developed at this french Animation Studio Les Fées Spéciales.
I notice them watching Amélie presentation at the Blender Conference 2022.

You can find the sources here:

This is a list of some of the most interesting add ons an a quick review. Will keep updating while testing them.

  • A color palette for quick pick up materials

  • A multiplane cam creator (2d GP layers)

/ Nuke Launcher for Linux (Centos) (.desktop)

Jorge Vidal

Installing Nuke on Linux doesn’t provide the icon launcher you have on Mac or Windows.

But you can manually create it.

I recommend this tips but you can go to step 2 for shorter version:

/ First of all. Create an alternative Nuke path.

  • I use to install the Nuke App outside my main local disk.

    This way I get a faster and better gestion on upgrading every three months and save more space.

    So, in my Workstation I download the .tgz compress app in my SSD (named SDT01)

    and this will be my Nuke folder:

    /run/media/user/SDT01/00_Apps_Backup/02_Nukes/Nuke13.0v2/Nuke13.0


    If you don’t wanna do the same, just keep in mind the path you have on installing nuke.


/ 1. Editing my bashrc


Then I get this path line (/run/media/user/SDT01/00_Apps_Backup/02_Nukes/Nuke13.0v2/Nuke13.0)
into my .bashrc script (located in my home folder) here:

/home/user

and write down as it drives my Nuke directory:

alias n='/run/media/user/SDT01/00_Apps_Backup/02_Nukes/Nuke13.0v2/Nuke13.0 --NukeX -nc'


Creating this alias I can launch nuke just writing “n” on my console.

This is just useful and faster, and you can create your own alias, as “patata” or “sugarbaby” instead “n”

NOTE: For watching on graphical mode the .bashrc script, use COMAND + H, because is hidden by default.


The launch comands provide you different calls to Nuke and the way you wanna launch the application.
Also you can use it for launching Hiero, Nuke, Nuke X, etc.
I’m using Nuke X in non commercial mode (—NukeX -nc)
Go to the foundry for specific launch comands, or just remove -nc at the end.

/ 2. Creating my .desktop launcher

Now, I’m ready to create my .desktop launcher.

The .desktop launcher will be another script you need to create as root into this folder:

/usr/share/applications

This way you are creating a link to the app using a desktop icon as windows or Mac.

(Also works in any directory, so keet it in mind, you need to mark it as TRUST and Allow executing file as program )

The right way to write the file is:

[Desktop Entry]

Name=Nuke.13.0v2

Comment=Nuke desktop shortcut

Exec="/run/media/user/SDT01/00_Apps_Backup/02_Nukes/Nuke13.0v2/Nuke13.0" --NukeX -nc %F

Terminal=true

MimeType=application/x-nuke;

Icon=/run/media/user/SDT01/00_Apps_Backup/02_Nukes/Nuke13.0v2/plugins/icons/NukeApp48.png

Type=Application

Categories=Graphics;2DGraphics;RasterGraphics;FLTK;

Name[en_GB]=Nuke.desktop



As you can see, I’m writing my path on the Exec line.
Write your OWN real path, and name correctly your Nuke version. On updating Nuke you must to do it recursively.
(Remove -nc if you have license and don’t forget the %F at the end.)

Ok, now log out, this way you will get the changes on your App launcher.


NOTE: This .desktop file can be also created at ~/.local/share/applications in case you have differente users.
Take in mind that on launching the .desktop as root, you will be root user using Nuke. It is preferible to run it as another (non root) user, with non-Administrative privileges.

The .desktop file also can be pasted on your Desktop, this way you can grab your script to the icon and Nuke will open it.
As you can see, it works at any place. But because it is executable file you must take care of the permissions.

/ 3. Open scripts directly in graphical mode

Last step is go to your graphical and click one .nk script + right mouse button and select Open with Other Application.
If your Nuke.desktop is right you can find Nuke in the list and select as default launcher for .nk files.

Easy!!! Now every time you double click on .nk will open the app.


/ 4. Set your mine list

Some times, the .nk file is not recognizable by Centos, then you must edit the mine list.

The mine list is which tell Centos that Nuke run .nk files.

Your .desktop file will work without the mine list, but is better to have it setted.

Here you can find the right way, at The Foundry. I’ve screenshot the main instructions.


/ Final thoughts:

Of course, you can use this tip on any application, as Blender.desktop.

Manage your apps in external drives, much more easy to update.

In opposition they can made your workstation more vulnerable, but you can solve it adjusting privileges.

/ Full Root Partition - tip for manage temporal files (also Nuke tip) on Linux Centos

Jorge Vidal

(updated September 2022)

A fast way to avoid full root partion due to lack of space on older Centos.

/ First look

If you use automatic partitions on installing Linux Centos you get annoying messages soon about being full on /root .

On my workstation it was set around 50 Gb.

df / -h
/dev/mapper/cl-root   50G   28G   23G  55% /

Sooner or later you would need to search a way to resize your /root which is irritating.

So I wanna share a small TIP. This way you wouldnt need to resize anything.

 

/ Check your troublemakers first:

First of all you must look as superuser whose are the main folders you use to get full recursively:

du -h --max-depth=1

If you prefer a graphic way use as user:

babobab

This way you can see graphically which are the most heavy folders that need to be cleened up.

Usually you will notice some folders whose are recursively filled by data and you need to recursively empty from time to time.
The global temporary directories are /tmp and /var/tmp

I use to play a comand for empty this files

rm -rf ~/.local/share/Trash/*
rm -rf ~/tmp/*
etc

But again an againg you lost your time removing trash so, what Ive done is very simple:

This is useful but just for temporal or shared folders, caches, etc. ; not a great idea for important root folders as it can do some damage or vulnerability to the system (you will see on rebboting).

I just use it when some apps download their cache data to root partition instead of my default user; this use to happen on installing as root or by managing preferences in a bad way.

A good example: Firefox downloads and Firefox cache. You can set up your download directory in preferences,
but there is also a caché folder which goes to /tmp/mozilla_user0 so I use my tip on this one also. When I dowload a lot of data I don’t want to full my root drive.

So now we go to a very simple tip:

/ TIP, move /tmp folder to another disk:

Look for your /tmp folder from your root partition.

/tmp

Copy that tmp folder at your /Documents or any place you prefer, or create one from scratch.

/home/user/Documents/temporalRoot/tmp

Create a “tmp” folder alias (dynamic link in linux) and place it where root use to have the original folder.
You will need first to delete the original one in /.
As simple as it is: you are linking the data to other drive area.

Finally manage permissions by chmod 775 or whatever you need. 

chmod 775  /home/user/Documents/temporalRoot/tmp

Generally there is some confusion about permissions, so you need to know:

There is a root folder (generally /tmp, which belongs to root)

There are other user folders (inside /tmp we can have user folders)

For example in case of Firefox, it will be the user folder, as it is user who has the right permissions (can write and delete, etc).

d rwx --- --- 2 user user mozilla_user0

In case of nuke folder should be similar: but due to license, nuke can be owner by user or root, so maybe you are running the app as user, but the real owner is root.

 

/ TIP for NUKE USERS:

When you run Nuke on first time, cache derivates to root device so usually this goes to /var/tmp/nuke-u100 so, any time you reinstall a new version you need to check that folder.

Very often this folder gets full and freezes your system while your /home user folder keeps being full of space.

I have a dynamic link on my root partition, so the temporal data goes to my home.

/home/user/Documents/TemporalRoot/nuke-u1000

Now my root partition use to get enough space and I can empty my temporal folders as non root user.

In case Nuke crashes or you would get an update, your cache won’t fill your /root partition if you forget to set up the preferences, because it will always search this folder.

I setup my permisses on this nuke-u1000 as:

d rwx rwx r—  7 root root  nuke-u1000


You can check your nuke default cache location in your preferences.

Nuke default cache location

Linux and macOS:

"/var/tmp/nuke-{uid}/" 

where {uid} is the users user ID on the machine, e.g. /var/tmp/nuke-u1737/



And here a reminder about permissions:

rwx = 111 in binary = 7
rw- = 110 in binary = 6
r-x = 101 in binary = 5
r-- = 100 in binary = 4

/ BONUS TIP: remove old kernels

As additional tip you can also remove all older kernels.

Centos keeps updating all the time, so at the end of the year you have lots of updates filling space. A way to clean them up is typing the next commands:

# list actual kernel
uname -a

# list older kernels
rpm -q kernel

# remove all except latest 1
package-cleanup --oldkernels --count=1
