Are you using luxcoreui command ? Is the scene exported from Blender ? In text or binary format ? We need more information.


sorry for the late response.
I used luxcorerender-v2.5-win64\luxcorerui.exe

hi guys, sorry, this was exported by FreeCad 0.19, but I tested out using the same scene from the LuxCoreRender v2.5 folder, same thing happens.

I am having problem getting LuxCoreRender to work with a w530 laptop fit with a Quadro K2000M .

I have a 980 GTX GPU, if I save the rendering with render engine set to PATHOCL, the next time I resume the render, the entire gui application would crash to desktop.
