v2.2 alpha1 released

New LuxCoreRender v2.2alpha1 release is available.

v2.2 release notes are available here: https://wiki.luxcorerender.org/LuxCoreR ... Notes_v2.2

New Features

* Added a new way to blend brute force path tracing and cache in PhotonGI. Cache is now used more often on glossy surfaces
* Introduced a new PhotonGI debug mode to show the mix between brute force and cached paths
* Added the support for automatic PhotonGI indirect cache best radius estimation
* Added the support for automatic PhotonGI indirect cache size by using convergence error estimation
* Front and back material transparency (aka light invisible object)
* Added PhotonGI support for volumes cache entries
* LXS parser now supports instance definitions
* Added the support for new "directx2opengl_normalmap" image map channel selection
* Added new textures: Power, Less Than, Greater Than, Dot Product, Position, Shading Normal

Fixed Bugs

* Fixed a problem with infinite lights and BiDir or PhotonGI
* Fixed a bug when using radiance groups with variance clamping and OpenCL
* Fixed camera invisible objects usage with volumes
* Fixed TASK_EMIT of LightStrategyPower
* Fixed a crash when using RTPATHOCL and editing area lights (issue #173)
* Fixed a bug when using radiance groups with variance clamping and OpenCL

This is the first release created with the new automated release pipeline, which was implemented by acasta69 - thank you a lot!

Hopefully, I made something wrong.


May you have a look at these effects and explain tem to me

I can't test right now, but maybe it's from because some objects don't have scale applied, so epsilon issue perhaps.
The ring noise i got one time with cornell scene when i limited max epsilon to 1e-6

The source of the issue is the3D mapping of the checker board. If set to local stripes and rings happen.
If set to global, needs different scaling, the rings do not appear.

The effect is not related to: epsiolon, type of light source, HDRI, Sky.

Please check the 3D mapping of textures. Thank you,

I think the global 3D mapping automatically applies a tiny offset, but the local mapping does not (?).
The fundamental problem is that the checkerboard texture is exactly intersecting the plane with one of its "sides". It's a bit like having two faces exactly on top of each other.
You can fix it by applying a bit of translation in a 3D mapping node.

By the way, I can't replicate the problem here - maybe it has something to do with scale after all? Can you upload the scene?

Blender crash when using Background image in LuxCore Imagepipeline in both final and preview render.

I can not reproduce this. Can you post the scene with the textures?

It works now! My background image was about (7000x5000px). I reduced it to 1920x1080 and it works.

So you probably ran out of (GPU) memory?
