[LPV] Emissive lighting fails
Emissive lighting fails to render on the ambient environment when configured to do so following these instructions in the documentation.
I'm trying to simulate an LED array - thus far I've setup my material in a way that seems to work as I would like it to look with parameters for the color and intensity:
Then I can put it into a blueprint to setup the color and intensity:
And it appears to get the fog within the blueprint preview, but without illuminating the object under it:
When displayed it does not manage to display any form of illumination, just the color of the plane (it's a 1-sided plane so you can only see a bit of the shading from this angle):
I tried following the instructions here to illuminate the objects in the world around the plane by setting it's
The effect I'm trying to accomplish is like the lighting from this video:
What is the best way to go about this? Do I need to create a bunch of different point light sources for each lighting panel? How do I get the fog to show if I do have to fudge the lighting with point lights instead of using the object's emissive properties to illuminate the objects around them?
Edit: I've tried point lights (can't use non-static ones without it failing to build them and need stationary in order to have adjustable lighting) and that wasn't a solution. There is no volumetric fog so that isn't a solution. I have changed this to a bug report as it is something included in the documentation that doesn't appear to work.
Hi CoryG -
Using Emissive for Static Lighting will only work for baked lighting and cannot be changed at runtime. You will need to have Precomputed Lighting turned on and you will need to build lighting for this function to work.
You can enable Light Propagation Volumes in your Project by adding the 'r.LightPropagationVolume=1' into the Engine's Console Variables INI file found in the Engine's Config Sub Folder. After doing that you can then check Emissive (Dynamic Area Light) to true in the Material. This will allow you to change the emissive color and have the color of the emitted light change as well.
In the Blue Array image above, the "fog" you are seeing is more probably Bloom and can be increased or decreased in the Post Process settings.
