The start distance can be set in a SceneCapture2D blueprint from the Draw Frustum component. Additionally, a variable who’s type is Draw Frustum Component can also set the Start Distance. Let me know if this is the information you’re looking for.
I’ve tried to use it this way but it seems it does not have any effect to capturing… Or I’m doing something wrong… Should this parameter create the culled area effect, as on picture? Or not?
Sorry for the confusion. Setting the view frustum’s start and end point doesn’t really influence the scene capture 2d.
You can define the culled area for a scene capture 2d however it takes a few steps.
You need to enable global clip plane in project settings
In the scene capture component you need to enable Clip Plane
Then define the clip plane base (this is the position the clip plane will be in world space)
Define clip plane normal (this is the orientation of the clip plane)
I went ahead and set up a small test project for you so you can see it in use. Select the clip plane actor in the scene and you can change the “Start Clip Dist” Value in the details panel to change where the clip plane will start. Open the render target named “Capture_RT” to see the results.
p.s. I’ve found the Clip Plane options for a Screen Capture 2D, but didn’t managed yet to understand how to place it properly (and it seems there is no docs about it…)
hey, I don’t actually remember, I think I have found a solution, but don’t remember which one You can check my old project about the portal: https://github.com/norlin/portal-actor
