Never stops rendering with LuxCoreRender, README needs a few lines of guidance.

[mangelozzi]

I followed the 4 step guide, using LuxCoreRender, however the rendering never stops. It just keeps going. I can't find information on where to set it to stop and return the render.

Maybe the README could be updated with some information. When one searches for answers to these problems one finds blender tutorials and outdated tutorials for FreeCAD Raytracing WB.

Well, I don't intend to substitute myself for the documentation of each renderer. But if you want to add some instructions to the doc, contributions are welcome. Some answers nevertheless:
LuxCore is by default an endless rendering engine.
If you want to stop it, you have to set up halt conditions, see here (e.g. via the command line).
To export rendering, the way I've found (I don't pretend it is the best) is: Tool --> Image View + Film --> Save outputs. Filename is set in Window --> Film Outputs editor

So where does LuxCore save the output render? I can't seem to find it anywhere on my PC.

LuxCore v2.5

Well, good question! I usually find it in my user directory, but I use Linux... And I'm sorry, I'm not skilled enough in Luxcore.
Maybe you should ask Luxcore devs? Or, as an alternative, you could set a very distinctive filename (with Film --> Save outputs) and run a complete lookup on your directory tree...

I did just as you suggested, searching for the file name. And then rendered 3 different FreeCAD files located in 3 different file folders (which I did for file organization).

1st file's Save Output showed up in the directory for the .INI file for the POV-Ray Rendering WB I had previously installed while waiting for a response to this question.

2nd file's Save Output showed up in the same file folder of the FreeCAD file.

3rd file's Save Output showed up in the same file folder as the 2nd file.

Then when I tried and uninstalled POV-Ray Renderin WB, LuxCore just closes (crashes?) when I hit Save Output, and the file doesn't show up in search.

It's like Russian Roulette! Can a dev from Rendering WB tell me show to set up the directory/file path where the rendered image goes? Because what's the point of being able to render your 3D models if you can't use them outside of the 3D modeling software?

LuxCore v2.5

Maybe you can try -d option on luxcoreui command line.

The steps to follow:

• Open Render preferences in FreeCAD (Edit --> Preferences --> Render)

• Edit LuxCore UI path parameter: in the command, add a -d option with the path of your target directory. Don't forget to enclose the target path into quotes, it's safer.

For instance, for me, the result looks like that: /usr/bin/luxcoreui -d "/home/howetuft/renderings" but please note I'm on Linux and the path points to my personal directory, so it's just to give you a general idea: you'll have to adapt it to your system.

Please let me know if it works (or not).

Maybe you can try -d option on luxcoreui command line.

The steps to follow:

* Open Render preferences in FreeCAD (`Edit --> Preferences --> Render`)

* Edit `LuxCore UI path` parameter: in the command, add a `-d` option with the path of your target directory. Don't forget to enclose the target path into quotes, it's safer.

For instance, for me, the result looks like that: /usr/bin/luxcoreui -d "/home/howetuft/renderings" but please note I'm on Linux and the path points to my personal directory, so it's just to give you a general idea: you'll have to adapt it to your system.

Please let me know if it works (or not).

Thank you! That Actually worked! I guess I'll just have to keep a repository for the render outputs then just move them to the right project's folder.

I wish they had a more "per render" way of setting up where the render output gets saved.

Fine! I close the topic...
