Does LuxCore have a cubic camera to render to a 360 cube map?

So that's the question.

We are going to render some 360`s and we could do that with separated cameras, but it would be much more efficient to render 360 pictures to a cubic render.
Does lux support it somehow?

Thanks!

We have a Environment Camera (a 360 panoramic camera):

No, I mean something along this lines:

The problem with panoramic 360 is that there is a lof of low quality information at the poles.

We don't have a cube one and it would be easy to add one but there may be some drawback with the Denoiser. It is likely to go mad with seams when going across different cube projection planes. At the end of the day, it is probably faster to do separate renderings (may be there is an add on to automate the renderings).

Yes, the denoiser can be problematic up to some point, but manual denoising in comp may be way easier than having to deal with seams, which is the bigger problem to render this as separated cameras :)

If I get approval for this project I’ll create a bounty for this :)

And then convert it with 'Panorama to Cubemap' online tool in an instant...
