Re: Normal Map DirectX to OpenGL

When you download a normal map and it says in the description that it's a DirectX normal map, then you have to use DirectX orientation in LuxCore.
For examples see https://dubcats-secret-little-hideout.f ... Normal_Map

Not in an official release, but you can use a daily build: viewtopic.php?f=9&t=736#p9704

Re: Normal Map DirectX to OpenGL

I have exposed this new setting in the Blender addon.
It's the "orientation" setting in the imagemap node:

Re: PhotonGI cache

Oh, yes, it is now 100,000,000 for LuxCore: https://github.com/LuxCoreRender/LuxCore/blob/afd6d12710efa05f5821edea75da64a208ab7365/src/slg/engines/caches/photongi/photongicache.cpp#L751 100,000,000 may be too much, consider this: the convergence test is run every 2,000,000 photons, how many max ste...

Re: PhotonGI cache

I have exposed the "use photongi" setting for volumes. It is available in the volume output node. NOTE: for obvious reasons, covering with cache entries a 3D volume is more complex than a 2D surface so there may be cases, like a large air volume for a large open scene, where it is not practical. In ...

Re: PhotonGI cache

I have added the support for automatic indirect cache size. Now, if you set path.photongi.indirect.maxsize to 0, PGI will automatically estimate the cache convergence error and stop when it is under a threshold (default: 5%). There is a new property to set the threshold: # Default 5% path.photongi....

Re: Tiled OIDN Denoising

(I don't know how to include this into the settings, so that it could be changed in the cfg file.) You can parse properties here: https://github.com/LuxCoreRender/LuxCore/blob/master/src/slg/film/filmparse.cpp#L603 Looking at the other plugins in that big if/else should help you see how it works, i...

Re: Normal Map DirectX to OpenGL

That's the first time I hear about normal maps with inverted green channel. I think the best (also for rendering performance) is to fix the map in an image editing program. If you invert the channel via shader nodes it's going to hurt the runtime rendering performance. Currently we have no nodes to ...

Re: Normal Map DirectX to OpenGL

I'm not sure what you mean. Blender uses OpenGL to draw its UI, and the Blender addon uses OpenGL in some places through Blender's API (bgl wrapper), for example to draw the viewport render or to show the point light radius. But it does not concern normal maps - they are handled internally in LuxCor...
