Re: Env. Light Visibility Cache

some more testing, assets are in empty space only lit by hdri cache on: kitchenasset_CACHEvismap.jpg cache off: kitchenasset_novismap.jpg artifacting seems pretty random to me, also like I mentioned before in mostly hdri lit case like product viz best performance is without visibility map altogether.

Re: Far end of shadow noise

nope, this is normal denoising. I haven't even seen tiled denoising in blender actually

Far end of shadow noise

This might be normal behavior but if there is an object currently in a far end of shadow of an object, that area won't get denoised. Not sure if noise samples are too far inbetween or there is a correlation but denoiser won't do anything with those areas unless they are very low in noise. In my test...

Re: Env. Light Visibility Cache

I was thinking about these feature speaking about environment lighting. The first one is this (that should be similar of what Dade developed before this Env Lighting Visibility Cache) https://docs.chaosgroup.com/display/VRAY4MAX/Dome+Light#DomeLight-IBL And the next one is this "Adaptive dome ...

Re: Env. Light Visibility Cache

Here's some of my amateur opninions about mapping and caching visibility. no mapping: nomap.jpg cache: cachemap_defaults.jpg It's just my opinion and I know it's early as this just got into luxcore, but I rather say it now since I don't see a happy ending for this cache :D Well, what I see is there...

Re: Env. Light Visibility Cache

... So I say, we need portals and abandon the whole vismap/caching method. People already know the caveats of using portals wrong, it's a pretty much a standard way of dealing with interiors and there is no time spent with setting up resolutions and sampling and then praying it will work. ... I don...

Re: Env. Light Visibility Cache

Here's some of my amateur opninions about mapping and caching visibility. no mapping: nomap.jpg cache: cachemap_defaults.jpg this won't go away unless I'm waiting until the worst area cleans and denoiser might afterwards still pick up the area as pattern and decide not to denoise that. These random ...

Re: Env. Light Visibility Cache

There is also another issue I'm seeing with both vismap cache and photongi cache. If I do render region/border in blender then it takes ages to start rendering. I think it is related to automatic size of cache, because in photongi if I disable automatic size of cache then startup for rendering goes ...

Re: Env. Light Visibility Cache

In some quicktest I've seen ~150-200 MB increase in ram usage. In complex scenes it can probably go higher, which isn't problem for cpu ram since we can have plenty there, but for gpus that go up to 8GB in mainstream range it can matter. I have also noticed that visibility map can even affect a rend...
