Alpha-handlinig? What is that?
Thanks for the Illustrator alternative. Will look into that, too.
When you create textures for real-time engines or just packing several maps to a single image, you need to manually tweak the alpha of an image and export is in 32 bit. An example is for this: RGBA where ‘R’ could be a Metallic map, ‘G’ could be AO, ‘B’ could be a mask and ‘A’ could be Roughness/Glossines (custom setup).
In PS you could display, copy, paste, eikt, etc. Alpha easily. directly and properly, in PL and any other app it was a PITA (finally I wrote a custom FF setup not to use any app for it).
Typical problem is that most of the image editors handles alpha as transparency while it could hold specularity, etc. info, too (any 8 bit info).
‘Thanks for the Illustrator alternative. Will look into that, too.’
I could give you suggestions like this:
DrawPlus for Corel/AI
PagePlus for InDesign (for Serif stuff register for the free version and buy it on Christmas at half price)
ShaderMap instead of CrazyBump
FilterForge for textures (I prefer it over Genetica)
Texture painting: 3D Coat (I prefer it over Quixel and Substance tools for most of the cases), also gives you nice sculpting
Video Editing: Sony Movie Studio (various collections) or HitFilm
You mention you created a custom FilterForge filter to accomplish this? Would you mind sharing it. or is it already available through the FF filters pages?
I sent a PM.
tried the developer version of Gimp 2.9. It doesn´t support openEXR but apparently there is a plugin for that. I couldn´t get it to work, though. Also, I read that it reduces the openEXR channels to 8bit images.
???
VERY ODD
i build the development version all the time
the git pull i have opens and saves milti(RGBA) layer OpenEXR’s at 32 bit per layer and SAVES them as 32 bit per layer
git clone git://git.gnome.org/gimp
now the last build i did was at the end of September
it is remotely possible that some recent change broke it
Hmm… On the Gimp homepage I followed a link to the nightly builds of 2.9:
http://nightly.darkrefraction.com/gimp/
I downloaded that and there was no way to import openEXR.
Now I just downloaded the newest version behind your link but I guess I have to build it somehow as there is no .exe file there or anything else.
What do I have do to get a working copy running?
<edit>I´m on Windows, so that might be the problem</edit>
it builds in MinGW on windows
or if you really are a software / code sadomasochist it can be done using MS Visual Studio
i do forget that i have been building gimp from source for almost 15 years now .
MinGW is a environment that builds Linux code on windows and makes Microsoft *.exe and *.dll’s
Is this something I as a complete layman when it comes to building software can do within a reasonable time frame?
Sorry for my ignorance but where can I get gimp 2.10 or 2.9, because in their official site I see only 2.8
For Microsoft Windows
http://nightly.darkrefraction.com/gimp/
has a nightly build that apparently is only mostly working – works iffy ???
for Linux or if you are building the code your self
git
git clone git://git.gnome.org/gimp
see the DEVELOPMENT section of the wiki

– Apple
http://wiki.gimp.org/wiki/Hacking:Building/Mac_OSX
– windows
http://wiki.gimp.org/wiki/Hacking:Building/Windows
on windows you can also build gimp using VisualStudio
but you will also need to build all the prerequisites in visualstudio
and ALL the prerequisites for the prerequisites , and all the prerequisites for the prerequisites of the prerequisites…
– a royal pain in the rear end
– good to do one time for the learning experience
GIMP 2.10 has not been released yet, GIMP 2.9 is the development version that could be unstable.
You do not download GIMP from anywhere, it can be unsafe. You just download GIMP from the official website, and from somewhere that you are sure it is safe. “Partha” is a known user from GIMP forums and he has GIMP 2.9 builds for Windows and Mac:

Regarding multilayer EXR, GIMP does not support natively this format (and I’m not sure if currently is working opening it through djv tools and plugin)

it works for me
red
green
blue
alpha
open and save
it also works using
Gmic and Nip2 and Cinepaint , and Krita
now i DO have OpenEXR 2.1.0-5.1.3 installed
and as with all software 32 bit float images do need to be between 0 and 1 in values
( like 0.0000000000001 and 0.99999999999999999 )
JohnVV, Are you sure? The other day when I went into the GIMP IRC channel, the developers were not interested in supporting multilayer EXR for now.
Can you see all the layers (layers, not channels) of this multilayer EXR in GIMP?:
If not, open it in Krita and see the layers.
yes for RGBA
two screenshots
this is not from blender but a 3d mesh in a image
red = latitude
green = longitude
blue = distance in RADII from center ( height)
gimp 2.9.1 development
used Autotools and gcc 4.8 to build with a “config.site” file for autotools ( basically a custom build folder), like i have done for many years
Currently i am using the latest stable 2.8.14 and a second build of 2.9.1
most of the programs i use do not make a distinction in red green or blue
those are just 3 bands of many bands
a spectrograph image might have 12 or 24 individual color bands from 350 Nm to 950 Nm
Can you open in GIMP the exr file that I shared above and I had obtained from Blender? I can not open it in GIMP 2.9.
Perhaps I misunderstood what they had told me on IRC channel, and they referred to EXR obtained from Blender.
For postpro, Fusion 8 (free). Make your render pass nodes with images, save them. Next time you render another project/render and render passes filenames are the same than you did in Fusion, woosh and they are loaded.
Wand mask for selecting mask on the fly from object/material ID passes.
Gimp for postpro is like a peeking in the keyhole, no full screen previews for (slow) filters.
The only issue with the free version of Fusion 8 is that it only allows for up to 4k resolution. That may not be sufficient for images.
Because you downloaded stable 2.8 nightly build? That’s my best guess.
On the contrary, the team will review any patches that improve support for OpenEXR. Bring it on.
Does that mean that the main developers are opened to review the code that others write for improve multilayer OpenEXR support? Or does mean that main developers have plans to write this code?
Yes, exactly that.
