📽️ SceneCapture

Scene Capture is an Actor which captures a fully dynamic image of the scene into a Texture. It captures the scene from its view frustum, stores that view as an image, which is then used within a Material.


💂Authority
This class can only be spawned on 🟧 Client side.

🎒 Examples

Client/Index.lua
local scene_capture = SceneCapture(
Vector(0, 0, 200),
Rotator(-15, 0, 0),
256,
256,
0,
5000,
100
)

-- Paints the Prop with the SceneCapture output
local my_prop = Prop(Vector(200, 200, 100), Rotator(), "nanos-world::SM_Cube")
my_prop:SetMaterialFromSceneCapture(scene_capture)
Client/Index.lua
local scene_capture = SceneCapture(
Vector(0, 0, 200),
Rotator(-15, 0, 0),
256,
256,
0,
5000,
100
)

-- Make a SceneCapture to only render a specific actor
local my_prop = Prop(Vector(200, 200, 100), Rotator(), "nanos-world::SM_Cube")
scene_capture:AddRenderActor(my_prop)
scene_capture:SetShowFlag("Atmosphere", false)
tip

You can use the output Texture from a SceneCapture with :SetMaterialFromSceneCapture() method!

🛠 Constructors

Default Constructor

local my_scenecapture = SceneCapture(location?, rotation?, width?, height?, render_rate?, view_distance?, fov_angle?, enable_distance_optimization?)
TypeNameDefaultDescription
VectorlocationVector(0, 0, 0)Location
RotatorrotationRotator(0, 0, 0)Rotation
integerwidth128Width of the generated Texture (max is 4096)
integerheight128Height of the generated Texture (max is 4096)
floatrender_rate0.033Render Rate (how frequent is the capture)
floatview_distance5000Maximum distance of capturing
floatfov_angle90FOV
booleanenable_distance_optimizationtrueReduces the rendering frequency if the entities with this Material are too far or not visible. Disable it to always render at the render_rate
note

Scene Captures capture a scene in real time, this means every tick it will re-render the scene from scratch. Please consider reducing the width/height and even the render_rate to improve it's performance.

We've worked hard to make SceneCapture as performatic as possible! Some techniques were applied for optimization and reducing the render_rate automatically when you are far and when the generated texture is out of the screen.
