how to properly bake lightmaps in unity if on a low end pc (rtx 3050 laptop 4gb vram)

[viral summit]

i wasted so many hours baking earlier with generate lightmap uvs off in import setting of models
now that i have figured that out i am greeted by this slow baking that looks blurry
i am tempted to switch to ue5 and lumen but it runs crap on my laptop and also i dont understand c++ or blueprints

This is what i am working with right now. it looks ugly from earlier bake and i am waiting for it to finish

Did it? Hard to give an opinion if the bake we see is using different settings than the ones shown

There's nothing really wrong with these settings, except maybe that

• max bounces are high (default is 2) which can make the bake take a long time
• Resolution is high, though 40 is appropriate for your scene it can take a long time (also Min Lightmap Resolution in each mesh's import settings should be as low as your bake Resolution, or you get seams)
• Compression on Low only makes the lightmaps look rougher, it won't help with bake times as the setting is for saving texture memory at runtime
• If your objects don't have normal maps, baking Directional lightmaps is an unnecessary cost
• I'd bake without Ambient Occlusion first when testing

Mostly this looks like a samples or denoise issues, but not something I've really seen before

Samples are fine as defaults but, if your GPU is weak, it might not support OptiX denoising properly

And it really seems to be if this kind of scene takes more than 20 seconds to bake
