Hi guys,
Lighting artist here, I have been trying GPU lightmass a bit. So far here are my observations:
• Blazing fast (RTX 2080 Ti). Turns hours into minutes. Using a low amount of samples + denoising makes wonders in such a small amount of time, it’s amazing.
• Baking trees with a rather high resolution looks possible at a wide scale.
• The infamous seam issue when baking modules is almost gone. It’s still a bit visible when using denoising, I guess it’s because denoising is done on the texture itself, so the system has no idea when 2 shells are contiguous. A great improvement nonetheless.
• I hit a limit with 256 lights being baked. Lights over 256 are ignored.
• Soft shadows do not work on spot lights (works fine on direct, area & point lights).
• Non invert-square attenuation is not accounted for when baking.
• Some VLM are getting weird illumination:
I have been waiting for this for years, and I hope for a swift & bugless release.
Cheers!
