[Forward] Realtime lights set to Not Important do not work with Shadowmask

Progressive Lightmapper


Realtime lights set to "Not Important" in Render Mode are not computed correctly in Shadowmask/Distance Shadowmask mode.

Steps for reproduction:
1) Download the project "" and open the scene "Bug"
2) Generate the lighting in "Subtractive" mode
3) Observe that realtime point light contribute lighting to dynamic object (i.e. Sphere)
4) Change the light mode to "Shadowmask"
5) Observe that realtime point light does not contribute lighting to dynamic object

- Lights that have their Render Mode set to Not Important are always per-vertex or SH. Vertex/SH light should be handled in shadowmask/distance shadowmask mode (i.e. occlusion should be computed on the CPU)
- In the reproduction scene, there is one mixed directional light, one realtime point light and there no light probes.
- On the image attached below, plane is light map static, sphere is dynamic
- It works correctly in deferred rendering path, but works incorrectly in forward rendering path.
- Not a regression, realtime lights set to “Not Important” never worked since the introduction of light modes

    Liialliset olosuhteet voivat myös saada aikaan useita kriittisiä tuhoja, ja juuri sellaiset takana olevat lenkkarit, miksi hiustenkuivaajasi on usein no-go-tapa, vahvistaa myös Angsuvarn. Löydät erittäin hyvän todennäköisyyden, että tämä korkea lämpötila yhdessä säännöllisen sekoittumisen kanssa tuhoaa polyuretaanivaahtoasi ja tuottaa väärinkäytöksiä <a href="">buste personalizzate</a>.

    This article offers an inside look at the “darker” side of online marketing – certainly not something we will be rolling out for clients at Web Profits anytime soon, but a very interesting insight into the craftily written ads and landing pages you’ve almost definitely seen all around the internet and the extremes these marketers go to to sell their products online.

    Can I simply say what a reduction to seek out somebody who actually is aware of what theyre talking about on the internet. You positively know easy methods to convey a difficulty to gentle and make it important. More people need to read this and perceive this side of the story. I cant imagine youre not more widespread since you definitely have the gift. <a href=''>Media box</a>
