LuxCoreRender v2.1/2.2 features poll

As discussed here, select the 6 most wanted feature for you.

Given the long list of features, they are likely to require a couple of versions (i.e. v2.1 - v2.2).

Denoiser is already part of v2.1.

Unbiased Photon Gathering for Light Transport Simulation and anditional photon mapping related techniques
WooHoo! A new toy! :D

And the winner is...
  1. Light cache Part II: to accelerate indirect light sampling
  2. Light cache Part I: to accelerate direct light sampling in scenes with many light sources
  3. Walt Disney Principled Shader material
  4. Displacement (micro, vector, volume)
  5. Unbiased Photon Gathering for Light Transport Simulation and anditional photon mapping related techniques
  6. Terminator Artifact Treatment
  7. Support for a native hair primitive to accelerate hair/fur rendering
  8. Support for multiple UV sets for each mesh vertex
  9. New Glossy material with multiple scattering GGX, Irridescent microfacets, etc.
  10. Normals auto-smooth
  11. etc.
A tentative split across multiple versions based also on the amount of work required by each task could be:

v2.1:
  1. Denoiser
  2. Light cache Part I: to accelerate direct light sampling in scenes with many light sources
  3. Walt Disney Principled Shader material
  4. Normals auto-smooth
v2.2/v2.3
  1. Light cache Part II: to accelerate indirect light sampling
  2. Displacement (micro, vector, volume)
  3. Terminator Artifact Treatment
  4. Support for a native hair primitive to accelerate hair/fur rendering
  5. Support for multiple UV sets for each mesh vertex
  6. New Glossy material with multiple scattering GGX, Irridescent microfacets, etc.
I'm keeping "Unbiased Photon Gathering" out of the picture for the moment because it may be a bit useless once we have light cache part I & II (we will see).

BTW, we are planning minimum 3 major releases for each year, better if we can do 4.

If only I've to choose i will keep For 2.1 development :

V2.1:

1. Denoiser (almost done)
2. Light cache Part I: to accelerate direct light sampling in scenes with many light sources
3. Light cache Part II: to accelerate indirect light sampling


IMHO This will catch a lot more testor and will place Luxcore in the range of best "efficient modern renderer" . It will also be a lot more easier to wait for next feature. Gallery will be completly saturated in a month (Just imagine the buzz on the blender community ). In this way the magnetic power is so hard i'm sure we can catch more dev's instantly.

I'm a bit in the same feeling but you're the coders and project manager...so it's up to you.

Well, it can be done (but as shown, it will require to put everything else on hold).

Sharlybg, prioritizing light-cache is a interesting strategy to get traction on the project, and is consistent with the poll's result. Would love to see more of your beautiful interior renders !

Would light cache help "complex path" renders, like caustics in pool or this one, like SPPM did ?

It is great to see the work, progress and motivation put in LuxCoreRender, thanks everyone !

No. It helps to sample lights better faster. (ie. psychopath renderer, Efficient sampling of many lights (@ompf2.com))

For BiDir caustics there's nothing alike SPPM out there. At least i haven't found anything better yet. Check the latest tutorial on caustics with appleseed and use compositing.

I actually like that the Disney BSDF is planned for the next release, I think it will bring a lot more users to LuxRender with the denoiser.
