ReflectionProbs
根據(jù)場(chǎng)景,劃分為3個(gè)主要區(qū)域蜕便,每個(gè)區(qū)域有一個(gè)ProxyVolumn, 這個(gè)作用簡(jiǎn)單的說(shuō):如果沒(méi)有這個(gè)姨伤,那么每個(gè)物體的反射效果哨坪,僅僅是反射球所在位置的簡(jiǎn)單重復(fù),所以我們經(jīng)痴С看到反射錯(cuò)位的現(xiàn)象当编;有了這個(gè)proxy,就可以精確模擬不同位置的反射情況徒溪。
注意:reflection proxy volumn
的形狀必須和反射球 的形狀一致
Reflection Proxy Volumes and reprojection
Reflection Materials in HDRP use Reflection Proxy Volumes as a reprojection volume to apply a reflection from a Reflection Probe. HDRP uses reprojection to correct parallax issues that arise due to the capture point not being at the same position as the surface point using the captured information.
If you do not use a proxy volume, when a reflective Material uses environment information captured by a Reflection Probe, it only provides a perfect reflection for the pixels in the same position as the Reflection Probes capture point. This means that Reflection Probes do not provide a perfect reflection for most of the reflective Materials on the screen and, instead, renders the reflected environment in a slightly different position. If you want an accurate reflection for a pixel that is not in the same position as the Reflection Probe’s capture point, use a proxy volume. HDRP uses reprojection to fix this displacement issue. HDRP projects capture information on to the Reflection Probe’s proxy volume and then reprojects it onto the surface of reflective Materials. This does not give a perfect projection, but it is much closer to the actual reflection than what an infinite projection gives. However, proxy volumes can potentially introduce some artifacts depending on the shape of the volume.
- A Box volume can potentially introduce resolution loss and incorrect angles at the edges of the box.
- A Sphere volume provides uniform quality, but you can sometimes see incorrect reflections on long surfaces that the proxy shape does not follow. For example, for a long plane, the reflections become less accurate the further they are from the Reflection Probe’s capture point.
每個(gè)區(qū)域的反射球設(shè)置多個(gè)忿偷,并且可以相互重疊。
注意臊泌,有些反射球設(shè)置了per axis control
體積光
使用這個(gè)組件模擬
注意這個(gè)組件用到了一張?zhí)厥赓N圖鲤桥,此貼圖參數(shù)如下:
光照探針
戶外少,戶內(nèi)多渠概,頂部少茶凳,底部多(遵循物體分布原則)
Decal
大量使用decal嫂拴,比如污漬、水漬贮喧, 甚至接縫處也使用筒狠,非常細(xì)致
Lights
室內(nèi)光結(jié)合使用realtime+mix類型,同時(shí)箱沦,射燈加上cookie辩恼;
- 同一處燈光,使用兩盞燈:
-
一盞燈為點(diǎn)光谓形,范圍較小灶伊,realtime類型,用來(lái)點(diǎn)亮燈罩
-
另外一盞為spot類型寒跳,范圍大谁帕,是主光,mix類型冯袍,名稱標(biāo)記lm亮度匈挖,并帶有cookie
烘焙設(shè)置
靜態(tài)物體
- 場(chǎng)景中較大物體如墻面地面桌子立柱等設(shè)置為全靜態(tài),小物體一般只設(shè)置反射探針靜態(tài)康愤;
-
極小的物體儡循、過(guò)于復(fù)雜的物體設(shè)置為動(dòng)態(tài)
