BlendLuxCore: Save image while render is paused

[Sharlybg]

This what i've done BYOB :

Code: Select all

 if LuxCoreDisplaySettings.paused:
            if not engine.session.IsInPause():
                engine.session.Pause()
                utils_render.update_status_msg(stats, engine, depsgraph.scene, config, time_until_film_refresh=0)
                engine.framebuffer.draw(engine, engine.session, depsgraph.scene, render_stopped=False)
                engine.update_stats("", "Paused")
                engine.session.GetFilm().SaveOutputs()
        else:
            if engine.session.IsInPause():
                engine.session.Resume()

the code display isn't respect indentation but it is roughly the change

after the line "import os", add the following command:

Code: Select all

                print(os.getcwd())

this will show you the directory where the file is saved in the Blender system console.

EDIT: for me on windows this is:

C:\Program Files\Blender Foundation\blender-2.81a-windows64

I've tested this, but Lux doesn't write an exr, only png, even when I set the output file type in the scene tab to exr

[CodeHD]

here you go, this works for me:

Code: Select all

        if LuxCoreDisplaySettings.paused:
            if not engine.session.IsInPause():
                engine.session.Pause()
                utils_render.update_status_msg(stats, engine, depsgraph.scene, config, time_until_film_refresh=0)
                engine.framebuffer.draw(engine, engine.session, depsgraph.scene, render_stopped=False)
                engine.update_stats("", "Paused")
                import os
                from datetime import datetime
                from ..bin import pyluxcore
                dummypath = os.getcwd()
                dummyfile = os.path.join(dummypath, '{}.exr'.format(datetime.now().strftime('%Y-%m-%d-%H-%M-%S')))
                engine.session.GetFilm().SaveOutput(dummyfile, pyluxcore.FilmOutputType.RGB_IMAGEPIPELINE, pyluxcore.Properties())
        else:
            if engine.session.IsInPause():
                engine.session.Resume()

EDIT: for me on windows this is:

C:\Program Files\Blender Foundation\blender-2.81a-windows64

My bad, I had started Blender from the BlendLuxCore project directory on Linux, which is why the CWD (current working directory) was there for me.

Saving outputs does not work on Windows on my end because it tries to write to a directory where you need admin write permissions (i.e. the Blender installation folder).
So either you have to change the CWD before saving the outputs, or use the function Dade mentioned, which accepts a filepath (but you need to know the output type and/or name, I think).

Here's code that's more into the direction of what you want (probably):

Code: Select all

                import os
                from datetime import datetime

                os.chdir(r"D:\my_renders")
                current_dir = os.getcwd()
                print("The files are in", current_dir)

                engine.session.GetFilm().SaveOutputs()
                date_string = datetime.now().strftime('%Y-%m-%d-%H-%M-%S')

                for filename in os.listdir(current_dir):
                    basename, extension = os.path.splitext(filename)
                    if extension.lower() in {"png", "exr"}:
                        os.rename(filename, basename + "_" + date_string + extension)

edit: if you want the imagepipeline outputs to be exr instead of png, you can remove "RGB_IMAGEPIPELINE" and "RGBA_IMAGEPIPELINE" here: https://github.com/LuxCoreRender/BlendL ... ovs.py#L11

Here is another updated option, which uses the output directory in the scene tab. Lots of code to choose from now
Only problem I observe here is that the filename extension you write overrides the file format setting made below. You might want to get the setting consistent and check if it outputs what you expect. I.e., BYOB was right here:

... or use the function Dade mentioned, which accepts a filepath (but you need to know the output type and/or name, I think).

Code: Select all

        if LuxCoreDisplaySettings.paused:
            if not engine.session.IsInPause():
                engine.session.Pause()
                utils_render.update_status_msg(stats, engine, depsgraph.scene, config, time_until_film_refresh=0)
                engine.framebuffer.draw(engine, engine.session, depsgraph.scene, render_stopped=False)
                engine.update_stats("", "Paused")

                import os
                from datetime import datetime
                from ..bin import pyluxcore
                import bpy

                dummyfile = bpy.context.scene.render.filepath
                dummyfile = bpy.path.abspath(dummyfile)
                dummyext = dummyfile.split('.')[-1]
                dummyfile = os.path.join(os.path.dirname(dummyfile), '{}'.format(datetime.now().strftime('%Y-%m-%d-%H-%M-%S')) +'.'+dummyext  )
                engine.session.GetFilm().SaveOutput(dummyfile, pyluxcore.FilmOutputType.RGB_IMAGEPIPELINE, pyluxcore.Properties())

        else:
            if engine.session.IsInPause():
                engine.session.Resume()

Can you share your python file. I mean the modified ( "" final.py""")

[CodeHD]

Sure

[Sharlybg]

Sure

Woahou it work

just need to reupload the file ""exr"" so i get all the color management stuff applied. It just need now an automatic ""EXR"" reload and save as a specified (jpg/png) extension to be user friendly. Sorry if i'm a bit bothering you. just want to include that in the light group tutorial. It make it so usefull and perfect

Thanks already for that.
