Re: Performance cost of a black constantinfinite light

The main problem is when the runtimeerror is thrown when scene editing, on calling EndSceneEdit(). It is annoying to handle and even if it succeeds, it stops the whole rendering just because the user has hidden the only light source for a brief moment. Getting a black render result would be much mor...

Performance cost of a black constantinfinite light

To make my life easier in the addon, I am considering to add a black constantinfinite light (always) in order to fix problems caused by the runtime error LuxCore throws when there are no light sources in the scene. Would this be detrimental to performance, or would this light just never be sampled b...

Oh, I see, BlendLuxCore is using an hold properties name "path.photongi.indirect.glossinessusagethreshold" while the correct name is "path.photongi.glossinessusagethreshold" because the threshold is used for caustic cache too in PGI, not only for indirect cache.
I fixed this in the addon.

Re: Why is there a limit of 8 lightgroups?

Oh, so my statement was wrong, it would have an impact even if no lightgroups are used at all.

Re: Why is there a limit of 8 lightgroups?

We could use a higher number if requested.
@Dade, I guess this would not raise memory consumption when the max. number of light groups is not actually used, right?

Re: Why is there a limit of 8 lightgroups?

Technically there's only a limit if you use an OpenCL engine, the CPU engines have no limit.
But in the Blender addon I'm always using the limit of 8 to make my life easier.

Re: Colour correcting HDRIs

I didnt't progress yet on arbitrary nodes, a lot more of the existing code base to uderstand for that... But I'm also not sure if that would matter with respect to writing the code above, or if it will be just a question of evaluating arguments to pass ? The thing is, if you implement contrast, hue...

Re: Cycles shader support

I will probably add support for more Cycles nodes in the coming months, but it is unlikely that we will support all of them.
You can see which nodes are supported here: https://github.com/LuxCoreRender/BlendL ... issues/272

Also I'm not sure of you know that for the daily builds you separatly have to install the LuxCore binaries?
This is no longer necessary since a while. Downloading BlendLuxCore latest build is enough.
