Why is 1 = 4.59? But it works in BuilInRP.īakery to 7.81. To get this i need these values in the bakery directional light and these values in the Bakery Skylight. Lit 3D wall in shadow = Lit IBL wall in shadow It will auto fit to the IBL used.Įven integrating a car look the same in shadow and lit areas like on the IBL.īakery L1 probes and Shadowmask is needed here. Now you could integrate real geometrys for arch and nature. You can freely run around and you have a total match in sun and shadow areas. There is a total match and the ibl lighting sceanrio from HDR which is fully captured to the bakery bake. Or brings up exposure by viewing on shadow wall. additionally you even have correct floor lighting in sun whats not avaiable in ibl because complete floor is in shadow thereĮven by running around the automatic exposure brings down exposure by viewing on lit wall. floor material in shadow matches reference wall material in sun and shadow matches reference ibl So after some time you come up with a bakery setting who matches real world ibl input 1) wall material in shadow = 2) wall material in sun Transfer Lighting scenario from IBL to Bakery bake.Īutomatic exposure in post processing should handle everything. Let s try some best practice real world example in BuiltIn RP to show off some stuff who drives me crazy because not archivable in HDRP now. The easiest way would be to make 'render in scene view' just use built-in HDRP postprocessing, but apparently SceneView.SetSceneViewShaderReplace doesn't really play well with it and I don't know any other way to force scene view shader override. Void BakeryVolume_float(float3 posWorld, float3 normalWorld, out float3 sh)īool isGlobal = dot(abs(_VolumeInvSize),1) = 0 įloat3 lpUV = (posWorld - (isGlobal ? _GlobalVolumeMin : _VolumeMin)) * (isGlobal ? _GlobalVolumeInvSize : _VolumeInvSize) Sh.b = shEvaluateDiffuseL1Geomerics(L0.b, float3(L1x.b, L1y.b, L1z.b), normalWorld) Sh.g = shEvaluateDiffuseL1Geomerics(L0.g, float3(L1x.g, L1y.g, L1z.g), normalWorld) Sh.r = shEvaluateDiffuseL1Geomerics(L0.r, float3(L1x.r, L1y.r, L1z.r), normalWorld) Tex2 = _Volume2.Sample(sampler_Volume0, lpUV) Tex1 = _Volume1.Sample(sampler_Volume0, lpUV) Tex0 = _Volume0.Sample(sampler_Volume0, lpUV) Void BakeryVolume(float3 lpUV, float3 normalWorld, out float3 sh) You can find the core functions in BakeryDecodeLightmap.hlsl:įloat3 _GlobalVolumeMin, _GlobalVolumeInvSize Take a look at URP shader graphs, because they show a way how it can be integrated. I tried to copy HDRP's EV100 logic to make RTPreview exposure work similarly, but because of the tonemapper, the result is pretty different anyway, so not sure syncing exposure alone would be useful:Ĭlick to expand.Totally. It was the safest bet because I can't guess which tonemapper is used (it can even be a custom one), and some tonemappers (hi ACES) tend to alter the image drastically. RTPreview doesn't have one, it simply multiplies the exposure.

Why does HDRP scene exposure even make the scene brighter when it's negative? Digital cameras usually do it other way around.Īnother problem is the tonemapper. HDRP's scale is something much more complex and (IMHO) less intuitive. I can probably hack it via reflection, but chances are, it'll break in a month after another HDRP update.īakery's exposure is just a linear multiplier. HDRP authors don't really want us to mess with it apparently. 'HDAdditionalSceneViewSettings' is inaccessible due to its protection level The whole thing is declared inside the HDAdditionalSceneViewSettings class, but I'm not sure there is any public API to get it.
