LuxCore: MacOS Standalone LuxCore.app broken after first Rendering
Just downloaded the newest macOS Standalone 2.4 version from the website.
Loaded Procedural Leaves from the examples.
Rendering once seems to work first hand.
Test wise switching to LIGHTCPU.
- Spinning wheel,
- unresponsive app does not recover,
- Fans going maximum,
- Screen buffer glitch (GPU buffer seems corrupted, OpenGL issue i guess from never ending loop somewhere or waiting for a semaphore that never comes).
- Volume gets data-spammed until full! EVIL EVIL EVIL…
after 3 minutes waiting, finally chose to hard-kick the app
Re-try. Opening second time. > Spinning wheel > no recover > Volume full > app needs to be erased and reinstalled. I need to tell, i had 30GB free HD space…
Is this intended behaviour? If so, there is major design problem
macOS: 10.14.6 Mojave, MacBook Pro (Retina, 15’, Mid 2015) Processor: 2,8 GHz Intel Core i7 Ram: 16 GB 1600 MHz DDR3 GPU internal: Intel Iris Pro 1536 MB

i rolled back, and as all have kinda same symptoms installed v2.5b1 to go forward. discord is fine…
It should work way back in v2.2 but the devs decided not to go after it or better to say it’s a driver issue.
https://forums.luxcorerender.org/viewtopic.php?f=5&t=2155first time app launch, no reaction. second time app launch, slow gui build up. immediately slows down the system, fans go crazy and i can not even open a project. When i wait a while i get two menu points inside the view… both don’t offer to switch the GPU device to Radeon, no menu point, no instructions seen yet.
Which is way i wrote its a design problem, not a bug at first. From my point of view it should never become unresponsive, not even on purpose when the app did nothing then just start up.
disabeling Iris… what the heck is that… You mean the GPU iris berbel nora… kidding But still i dont know Iris. 😃 I may have to explain, i develop in metal, c++, objc, swift, python. Never heard of it…
Oh just saw you are using GPU internal: Intel Iris Pro 1536 MB
Intel GPUs are very buggy and are not supported in LuxCoreRender. As Dave said “As Developers we don’t touch it. Not even with a 2m long stick”.
This means the compilation fails. Which describes the behavior you witnessed.
Use your dedicated GPU but don’t expect too much from Mojave factory NVIDIA drivers. Will take forever compiling the kernel.
For best Performance on NVIDIA switch back to High Sierra and use the NV webdrivers and CUDA 10.1.
And Always disable Iris ! Always !
