I was just working with the new luxcorerender, and wanted to post some tips anyone who wants to try it:
1) You can download it from the new address - https://luxcorerender.org/
2) Luxcorerender should be able to render the old luxrender scenes (.lxs files) that reality produces
3) EXCEPT THERE IS CURRENTLY A BUG
that throws an error when trying to load most scenes that use emission textures (e.g. reality meshlights). I have submitted a patch for this bug, but it probably won't be in until the next release - until then, you will probably get an error message about a bad IES definition
. You are not doing anything wrong, you just have to wait till they publish the version with my patch.
4) The current stand-alone UI (luxcoreui) is really for development purposes and is pretty hard to use - it sounds like they are going to put together a more user friendly stand alone render app like luxrender had; however, I don't know when this is scheduled.
5) If you are trying to open a getting an error that says something like "PATHOCL missing," it's probably because you didn't download the OpenCL (GPU accelerated) version of luxcorerender. (There also might be a bug that always starts lxs files up using the PATHOCL renderer, I'm not a developer on the project, but I'll look when I get more time.)
6) Luxcorerender should be much faster than old luxrender
7) If you want pretty caustics with luxcorerender, you need to use the BIDIRCPU rendering engine - GPU acceleration doesn't support a bidirectional renderer
To try it out:
1) Download the OpenCL version from https://luxcorerender.org/
2) Open the standalone UI (luxcoreui)
3) Go to Rendering->Load and select a lxs file created by reality
4) It should render*
* EXCEPT FOR THE BUG NOTED ABOVE - it will actually probably give you an error about light IES not defined. I have submitted a patch for this, and it should hopefully be fixed in the next version they release.
