Re: Normal Map DirectX to OpenGL

I added the support for a new image map channel selection option: "directx2opengl_normalmap"

It should do the job.

Re: PhotonGI cache

guys... so no one comments on the fact that logpower+photongi+multiple lights is broken but logpower is still default option!? Am I missing something here? The problems is: 1) if the sun/sky are more important than other lights for the scene to render, logpower is the right strategy. For instance i...

Re: Ply ASCII

I have added the support of old LXS way to define instances and now the scene you posted seems to work fine:

Re: PhotonGI cache

Are cache entries only stored on homogeneous/hetereogeneous volumes, or in clear volumes as well? Cache entries are stored on path vertices and you can have a path vertex only on surfaces or volume scattering points so clear volumes can not have entries (because they do not need). Yes, I guess you ...

Re: PhotonGI cache

Maybe we should increase the default photon maxcount? In my tests the convergence test did not really kick in with 100,000 photons. Oh, yes, it is now 100,000,000 for LuxCore: https://github.com/LuxCoreRender/LuxCore/blob/afd6d12710efa05f5821edea75da64a208ab7365/src/slg/engines/caches/photongi/phot...

Re: Normal Map DirectX to OpenGL

We have the support for image maps pre-processing for stuff like using the a single RGB channel or using the average, etc. We can add also this "DirectX to OpenGL" translation (aka right-handed to left-handed normal maps :?: ) if it is something may be useful for more people :?:

Re: Ply ASCII

if I ungroup the objects it then works, that's not a practical solution that's going to cause some really horrible geometry I need a test scene showing the problem and an explanation/screenshot of how it should render instead. I have downloaded the latest scene you posted but it renders fine, the p...

Re: PhotonGI cache

I added the support for volumes to PhotonGI. Now cache entries can be created and used on volumes too: bm2.jpg It can increase the raw samples/sec by a 50%-100% and reduce the amount of noise too: media.jpg In particular, it greatly accelerate the rendering of multi-scattering volumes and it is indi...

Re: Ply ASCII

The camera part of the LXS seems to be totally ignored if I run it in luxcoreui, everything else seems fine, the scene has models and texture I thought it was maybe FOV but that appears right, rendering the camera is lower and very close The code to parser the LXS is there: https://github.com/LuxCo...
