LuxCoreRender Forums

It is time to start to think to the features to include in v2.3. I'm opining this thread to collect requests and idea. We will than make a poll to decide priorities.

v2.3 will be mostly focused on small and/or quality-of-life features. It supposed to be released in few months, not a year.

The first new feature of v2.3 is already under development and is: SDS path rendering (aka PhotonGI new caustic cache).

The other candidates for LuxCore are:

• Extend our SIGGRAPH 2012 Disney material to include SIGGRAPH 2015 new features (https://github.com/LuxCoreRender/LuxCore/issues/91)
• Support for multiple UV sets for each mesh vertex (https://github.com/LuxCoreRender/LuxCore/issues/134)
• Support Corona-like hybrid glass (https://github.com/LuxCoreRender/LuxCore/issues/233)
• Reduce the number of OpenCL kernel compilation required
• Triplanar mapping with blending (https://github.com/LuxCoreRender/LuxCore/issues/153)
• Add an image plugin to write over the image (https://github.com/LuxCoreRender/LuxCore/issues/45)
• Procedural stochastic texturing (https://github.com/LuxCoreRender/LuxCore/issues/228)

Post your candidates for BlendLuxCore and LuxCore and I will update the above list.

Updated list:

• CUDA/Optix 7 with RTX hardware support (aka fu@k small and/or quality-of-life features )
• Extend our SIGGRAPH 2012 Disney material to include SIGGRAPH 2015 new features (https://github.com/LuxCoreRender/LuxCore/issues/91)
• Support for multiple UVs/Color/Alpha sets for each mesh vertex (https://github.com/LuxCoreRender/LuxCore/issues/134)
• Support Corona-like hybrid glass (https://github.com/LuxCoreRender/LuxCore/issues/233)
• Reduce the number of OpenCL kernel compilations required
• Triplanar mapping with blending (https://github.com/LuxCoreRender/LuxCore/issues/153)
• Add an image plugin to write over the image (https://github.com/LuxCoreRender/LuxCore/issues/45)
• Procedural stochastic texturing (https://github.com/LuxCoreRender/LuxCore/issues/228)
• Porting of procedural Cycles/Eevee textures to LuxCore
• Micropolygon displacement
• Bevel shader
• Dirt shader
• Light linking (https://github.com/LuxCoreRender/LuxCore/issues/147)
• Coating film interference (https://github.com/LuxCoreRender/LuxCore/issues/175)
• Rayswitch (https://github.com/LuxCoreRender/LuxCore/issues/148)
• Geopattern (https://cgpress.org/archives/fstorm-tea ... ttern.html)
• New complete Bidirectional path tracing with vertex merging (BIDIRCPUVM)
• Principled hair BSDF shader and dedicated hair geometry
• Bokeh texture / Optical vignetting support (http://bertrand-benoit.com/blog/wonky-bokeh/)
• Fixed and faster env. visibility cache
• Custom color management inside Blender to match LuxCoreUI (and network renderings)
• Custom split normals support in Blender
• An option to store compressed image maps in GPU memory
• Support for 3D LUT (.cube)
• PhotonGI support for light groups
• Path guiding for Bidirectional path tracing
• Add procedural textures specifically tailored for heterogeneous volumes (for instance clouds, fog, sand clouds, fog, sedimenting heterogeneous mixtures, fruit juice, milk, turbid lakes)

On my wishlist is porting over the procedural textures in Cycles/Eevee to LuxCore so we can be more compatible in this regard (like we were in the past with Blender Internal).

Support for blender custom normals
Micropolygon displacement
raytraced bevel shader
raytraced ambient oclusion/dirt texture (with support for mapping distance)
fixed and faster env. visibility cache or portals as alternative solution
light linking https://github.com/LuxCoreRender/LuxCore/issues/147
coating film interference https://github.com/LuxCoreRender/LuxCore/issues/175
rayswitch or at least this https://github.com/LuxCoreRender/LuxCore/issues/148
geopattern like scattering: https://cgpress.org/archives/fstorm-tea ... ttern.html
texture caching in ram?

The LuxCore standalone ui now can't read render resolution from scene file. This breaks all the new cache and pre generation of different sampling features, that take long time to repeat 2 times. Current working solution is to compile 10 different LuxCore versions wit 10 different default resolutions.

- Fix BiDirVM and make it available in Blender!
- Implement persistent cache for DLSC and EVLC in LuxBlend #293

My wish for that topic would be to disable the auto start functionality with the GUI open file menu (display start icon instead) so that the user can make changes to different parameters before starting the rendering.

Just set the resolution from command line.

"This is madness. This is Sparta."

-Custom split normals support
-Bevel shader
-OpenCL kernel compilation optimisations
-Principled hair bsdf shader

Would love to get Bokeh texture / Optical vignetting support. Some longitudinal chromatic aberration?

@lacilaci
It looks like my wishlist is a subset of yours! I'm interested in (excluding some features already in Dade's original post):

1. raytraced bevel shader
2. raytraced ambient oclusion/dirt texture
3. light linking https://github.com/LuxCoreRender/LuxCore/issues/147
4. rayswitch or at least this https://github.com/LuxCoreRender/LuxCore/issues/148

Point 1 and 2 are very nice-to-have features for me, and point 3&4 are the main deal-breakers for me to transition some of our scenes from VRay.

BTW: I don't know what is rayswitch, and only interested in issue 148, but I guess your use case might be similar to mine, so could you tell me how would you use rayswitch? Maybe I'll added it to my wishlist after understanding your use case
