View attachment while cascade blending would be an improvement and it is definitely something we are investigating, it is a bit of a hacky workaround for the perspective aliasing and has considerable performance implications, and I would prefer for us to focus on a smaller improvement that allows us to restrict the depth range so that we do not undersample as badly with negligeble perf impact. We still need to evaluate performance on mobile, but the decals implementation has a really cool performance optimization, which we will detail in a blog post.
The documentation and sample workflow (by are in progress. We really apperciate all of your feedback, as it is invaluable to The receive shadow setting is now per material so that you can have sub-meshes and then set shadow receiving per-material.Ģ021.2 now has decal projectors which can be used to render blob shadows (and fake lights). We want to make sure that all improvements and new features we introduce are compatible with each other, while also being stable and performant across all platforms. While some of these are pretty easy to get running on a single platform, getting them to be performant and stable across all platforms can be incredibly challenging, and some of these improvements are inter-dependent as I mentioned, so there are significant considerations especially in regards to other new feautres.
I'll try to get some cards added to our roadmap with more details about some of the improvements so that you all can vote and help us prioritize them. Slope scale bias is also in progress, though this is something that is interdependent with other biases improvements. In 2021.2, we also made signficant improvements to the quality and control of shadow fade in URP.Ī critical improvement to shadow frustum culling is currently in progress with regards to culling spheres, which actually affects all SRPs and built-in. I'll go into detail about this at a later time.

#DROP SHADOW AFTER EFFECTS NOT SMOOTH UPGRADE#
Bias improvements need to be done in major release versions, since the upgrade will require you to adjust the biases across all scenes.Ģ021.2 now has decal projectors which can be used to render blob shadows (and fake lights). The only thing we actually have as a higher priority at the moment is moving the shadow depth bias from the caster to the receiver, as that would be a huge improvement in quality. Until this time I have to use a hacky workaround with cookies, and it's not great! but here is hoping that cached shadow maps with per-object granularity makes it's way in The receive shadow setting is now per material so that you can have sub-meshes and then set shadow receiving per-material.Ĭached static shadows is very high in priority on our raster shadow roadmap. For example (this is also in Alyx) in VR, I would be building up a cached shadow map at my own pace, usually within the budget of the device (Quest 2 / etc) in the next room or area before the player reached it. I would love cached shadow maps that can be lazily updated (could control per object - determine if its realtime or cached on demand). Until this time I have to use a hacky workaround with cookies, and it's not great! but here is hoping that cached shadow maps with per-object granularity makes it's way in sometime. AAA games all have this, it's a shame we do not (yet!) The reason I feel the behaviour should be built in is because it's really a massive optimisation for most devices URP will cover, from mobile to VR. dynamic shadows are just way too expensive and not even needed for a large amount of the rendered frame.
#DROP SHADOW AFTER EFFECTS NOT SMOOTH UPDATE#
In Alyx's case, when you let go of moving objects and they settle, you can see the cached shadowmap update with a screendoor effect of the object - a tad polished but you get the idea!Īs you can imagine it pretty much makes shadows almost free for vast levels.
