Colour correcting HDRIs
First of all, I absolutely love Luxcore! It's everything I was missing in cycles.
Usually in cycles I would alter the colour of my HDRI by adding a hue/saturation node in the world tab, but I can't find anywhere in Luxcore where you can change the HDRI other than in the world tab.
Is it possible, or will I have to do the corrections in Photoshop?

Welcome Birk !
Currently you have two way to change your HDRi color first :
The second fashion is by lightgroups :

Sharly, first of all, thank you so much for all your tutorials!
When I change the tint nothing happens?

Apparently it broke during the light settings rework in v2.3.

Re: Colour correcting HDRIs
Light sources in LuxCore currently do not support arbitrary texture node trees, so the answer is that you need an external program.
You can make a feature request for light source node trees by opening an issue here: https://github.com/LuxCoreRender/LuxCore/issues

Re: Colour correcting HDRIs
The general idea is that anything doable at pre-processing stage, should be. We have already many type of image maps pre-processing (i.e. gamma revers, channel selection, grey scale, etc.): adding HSV balancing would be quite easy
P.S. I don't have the time but if someone want, it should be easy.
Re: Colour correcting HDRIs
I'm thinking more in the direction of applying arbitrary node trees to image pixels during pre-processing. Of course it only makes sense if the image is only used in one place (otherwise we would have to make a copy per differing node tree) but for env. light HDRIs, it would be perfect.

Re: Colour correcting HDRIs
This is why I much prefer more independent render engines! There's actual people to chat with and an eagerness to make changes and implement new features
I'm currently doing tests to find out whether cycles, Luxcore or Octane best suit my workflow.
