Hi there,
I am using a render texture target cube to generate several HDR images to use with my interior mapping setup for an architectural night time scene. The scene is using lumen and a directional light for the sun, with a post processing volume, sky atmosphere, skylight , volumetric clouds and exponential fog. The scene renders perfectly well, however when I want to make HDR’s i use a Texture Render Target Cube but the scene appears dark in the texture. Placing a light source in the model brightens the Texture Render Target Cube, making the scene more visible, but why can I not get the render quality from the viewport in the target cube texture?
Bumping this. I’m having the same issue. Almost seems like the issue is that the render target isn’t factoring in any indirect light. Could this be a problem with Lumen?
I actually just finally found the solution to this!
If you have “Capture Every Frame” disabled on the SceneCaptureComponent2D, you need to then enable “Always Persist Rendering State” (in the same details panel). Once you do, the darkness should be fixed. This also allows you to make adjustment to the post processing options on the SceneCaptureCompnent2D.
