I’ve been testing LuxCoreRender recently and I’m really impressed on how well it handles caustics. The scene is entirely illuminated with light refracted trough glass, which is quite impressive!
Due to its unbiased nature the final render was quite slow, I set the timer for 2h. The denoising algorithm does a great job so I think I could render the final image in much less time. Previewing was quite fast due to the denoiser and the amazing bidirectional path tracing algorithm, so it was surprisingly easy to work with consider the complexity of the calculations.
Hope you like it :3
