BlendLuxCore Alpha5 Bugs

[kintuX]

BlendLuxCore alpha 5 & Blender 2.79a RC
Windows 7 SP1 x64


1. I have a conflict with one of the "addons_contrib" (or? i don't know which - am looking for suspects), preventing registration of LuxCore. LuxCore Engine is not available. Removed them all (only base addons used) LuxCore is found and can be activated.

- also note
console writes: "pyluxcore version: 2.0alpha4"

2. Fresh & Clean Installation
On one occasion with 'atollo238_bug.blend' scene, since it was still crashing i then used "Only write LuxCore scene: Binary", i got couple of errors:
- twice

Code: Select all

Undefined property in Properties::Get(): renderengine.type

& then (3rd)

Code: Select all

Traceback (most recent call last):
  File "C:\programi\b279aRC\2.79\scripts\addons\BlendLuxCore\engine\__init__.py", line 54, in render

During handling of the above exception, another exception occurred:

3. Cleaned it all again, started fresh Blender version and this time "Only writing files" succeeded (both: CPU & OCL).
Rendering with luxcorerender-v2.0alpha5-win64-opencl:

I. OCL version: started fine but then it crashed...

II. CPU version: Rendering went fine (left it up to 4k passes), CPU/RAM performance was stable (no strange jumping or peaks/valleys) & the system was still well responsive through the process

III. OCL version again & this time it went fine (left up to 5K passes) stable, without any hiccups.


PS
Still using older drivers. Will update now & report back.
Also, will try to find the addon which is causing a conflict (blocking LuxCore).

[kintuX]

Drivers updated to latest. Windows updated. Using clean Blender 2.79aRC installation.
Still getting regular crashes with OCL & now also occasional CPU crashes...


& About the installation with LuXBlend not being registered
Error from console at start:

Code: Select all

AttributeError: module 'BlendLuxCore' has no attribute '__file__'

Made me check & i soon realized that 'BlendLuxCore' (addon folder) inside another 'BlendLuxCore' (folder) is the cause. My mistake.
another day, another lesson learned

[kintuX]

Newest (latest) alpha5
Still... Always crashing with OCL (fresh scene, old scene, used to be working scene... even only with cube, plane, sun & HDRI)
as already mentioned, had crashes with every version (made available) after the alpha4 'pyluxcore.pyd' was changed

& still learning ...

thanks for it all & bye-bye

Disable the visibility map for now, crashes for me too always on luxcoreui, any build
Oddly pyluxcore works.

Which Visibility Map?

[B.Y.O.B.]

In the world and/or hemi light settings, open the "performance" panel.
There's a checkbox named "Build Visibility Map".

Which Visibility Map?

Or if you have an exported .cfg already, find and change:

Code: Select all

scene.lights.__WORLD_BACKGROUND_LIGHT__.visibilitymap.enable = 1
scene.lights.__WORLD_BACKGROUND_LIGHT__.visibilitymap.enable = 0
