Before baking, check your project’s Quality & Player settings. When baking, you can improve lightmap quality by increasing the baked resolution slider (40–100 texel resolution is reasonable), cranking up the ambient occlusion and enabling final gather. of player movement) but tricks can compensate (see “light probes” below). Baked lighting & shadows don’t change to realtime dynamic object movement (ex. Especially with the constraints of VR, baked light should be used much as possible. Baked lighting produces higher quality results & reduces performance requirements. Real-time lighting is only needed if change something about the light (color, position, etc.). With baked lights, you see a soft, diffused shadow under the table). (example: spotlight over a table) With a realtime light, you see a blocky shadow underneath. Hard/soft is sufficient for some, but looks horrible in many cases. If you care about realistic shadows, bake the light.

In each rendering pass, each object that a pixel light hits gets rendered.The cost of a forward renderer is proportional to the number of lights in the scene. Does your scene only have a couple realtime lights? Go with a forward path. No anti-aliasing (this is especially bad for VR which benefits greatly from MSAA to reduce shimmer and flickering lines)įorward rendering has a low upfront fixed cost, and thus is best for low complexity scenes, but its performance cost scales up with complexity.So many draw calls (2 draw calls per object in scene * 2 draw calls per light in scene).They affect the entire scene, with an enormous light volume. Directional lights are very expensive in a deferred renderer.You’ll need an additional forward pass for this. Deferred renderers cannot render semi-transparent materials.Every light can be rendered as a per-pixel light, giving you accurate shading on normal & depth maps.

Deferred rendering works best in scenes that require a large number of small realtime lights.Sidenote: UE4 only has a deferred rendering pipeline, which is one reason why many VR demos made with UE4 run slowly on old PCs. Scene complexity (number of objects that a light hits) does not affect performance. The cost of a deferred render is proportional to the number of pixels that a light hits (the light volume). Do you have hundreds of small realtime lights? Go with a deferred path. Here’s a quick overview to help you decide which pipeline is right for your application: Deferred Renderingĭeferred rendering has a very high upfront performance cost but it’s a fixed performance cost, allowing you to add a ton of geometry and a ton of lights without much extra cost. Forward rendering has a low upfront performance cost, it’s easier on the CPU with fewer draw calls, it runs well on mobile VR devices, and it supports anti-aliasing as well as translucent materials. It’s ideal for VR applications for several reasons. When in doubt, go with a forward rendering path.
