Not sure if a Revit or Enscape issue. But I need my interior lights on during the daylight hours so I can see an interior lit up through an open garage door from the exterior. Anyone have an idea what I'm missing on this or a workaround? Thank you ahead of time if you have an idea to post. The lights go on correctly of course as dusk approaches and night falls. But that's not helpful in this case. This is a warehouse with no windows in the desired region.
Lights are off during day and that's a problem

my lights are on during the day, must be a light setting in revit not enscape

I have tried adjust Revit's rendering settings and sun settings. Exterior Sun and artificial, interior Sun and artificial, interior only, exterior only. I have overblown the lights by 150,000 or more. I'm just not seeing anything change in my exterior view in Enscape that is set of course at around 2pm. Right now I'm thinking I'll have to adjust the time later and then get freaky with the other settings. That or export two images, one of dusk and one of daylight and PS them.

Thanks Scott. I'll have to keep looking for what setting I'm missing. As far as I can tell my lights are set to on. They do show up as on at dusk or night time in Enscape. They also show very brightly now at night since I've kicked lumens up into higher orders of magnitude.

Oddly enough, I noticed if I set the Rendering Engine in Revit to Raytracer instead of Nvidia mental ray my model building completely drops out of the Enscape scene. The site stays and a set of lockers on the interior stay, the rest of the building vanishes immediately. Setting back to mental ray I guess.

I have the same issue, lights off during the day but switch on at a certain point. Not sure what time though

Be sure to have the sun brightness set to 100% to allow for a correct relation between sun light and your artificial light sources. Enscape does not toggle your artificial lights on or off but they might become invisible due to a much brighter sunlight.
For emissive surfaces: Right now, they only create a glow and illuminate a short area around them. The surfaces affected by emitted light will be increased, it's already implemented at the current Enscape for Revit Preview version.

Hi, we just purchased a floating license after a web session I had this morning. Soon after I began testing some interior setup with artificial lights on, I intend to use both sun and artificial at the same time (say late afternoon shot), but I cannot the see the artificial lights unless I choose a time after sunset? I tried setting it at 100%, didn't work either. Is there a standard way we need to create light fixtures that work with Enscape rendering? I realize that only point lights work with Enscape but some built-in REVIT lights are not linked to any IES files.. are they required to?

Thanks Thomas and dsmith86. I'll check those sun settings. That might be part of it, with the sun washing out the interior lights. It appears some of the lights just don't appear to work during the day or simply can't compete with the sun. For an update, I have found that studio lights are visibly on, at least when cranked to something like 700,000 over. Troffer lights I had put in the building don't appear to be on no matter what I crank them up to. I'm just going to add cranked up studio lights below them and deal with all the strange shadows I'm going to get for now.
edit. Looks like I might need to look more closely at what lights I'm choosing. Thanks nvanamudi. I'm going to check out the example lighting file for working types.

A workaround could be using the light material from the Enscape ies revit project, they seem to be 'on' during daylight hours as well as after dark hours. It'll be a bit of a work but maybe create some mass around where the light fixture is and apply the same material to it?
-
It's important to know the difference:
- Emissive: Material option, produces glow, but no real light impact at current Enscape version (Will be changed soon)
- A light: Not geometrically visible itself (as a dot or similar) but creates light in a defined radius around it
At Enscape, there is no way to define lights that go on or off at a certain point of time. Either it's an illusion because the sunlight is very bright and makes the artificial lights invisible, or it is a bug. We'd be happy to get a Revit project from one of you where this issue happens because we haven't seen such thing before. Please just send it to support at Enscape3d.com. Thank you!

Working years with REVIT taught us (or me) a lot of patience and how to tweak stuff so they work (no pun, just fact).. that said.. I finally managed to make the artificial lights work during the night shot, by increasing the light lumens to 10,000+, and ended up with shadows being cast from the ceiling mounted fixtures. Normally these fixtures are a bit transparent and create this ambient diffusion around them and fill the room. See attached for renders Enscape vs Revit raytracing. Note that there is only ceiling fixture in raytrace render but everything else is same. There are invisible lights in both renders,, (no fixture body just light family for extra lighting)
-
UPDATE::
After struggling to make the lights work, I followed Enscape tip and separated the light from fixture and shadows were gone. The light fixture domes are self illuminated though . I think IES embedded lights are the best way to go. Also notice the circled items, the render of the metal (sconce and pendant) is not good enough, what needs to be done? This is the highest quality render. The colors on the final output does not match with the raytracing 'per se'. Any input is appreciated. Thanks

Actually I noticed there is a way to define and I don't know if it's right or wrong. I usually set the time/date of the view thru revit, If the time is set at sometime during the dusk/dawn the overall rendition changes to warmer tone and the lights are on. Maybe Enscape team can clarify. Also I have trouble rendering metals, did anyone else have this problem, the colors are off and metal textures are pixelated.

That should be connected with the auto exposure. During the day the sunlight is so bright that it's smashing your lights.
You could try to turn up your lights (more lumen) and to deactivate auto exposure, set the sun to 0% and increase the exposure brightness.
-
The same issue is occurring for me.
Now I realize my lights need work, but in the day (11:15 am) my space is MUCH darker than in the night (4:15 am). I think there is some sort of daylight compensation taking effect which is causing some oddities in certain scenarios.

This effect is caused through the auto exposure. The auto exposure works like it does in your eye or digital cameras: It detects the brightest spots in the image and adjusts accordingly so that they are properly exposed. If you would only take the average, nothing would look correct in an image with high contrasts.
In your case, the exposure dims down the exposure time because it do not wants the bright sky and outside if the building to be overexposed.
But I agree: It requires a bit of tuning on our side, I'll see what we can do to make it look right.

Hi, Do you have a video explaining the relation between Artificial Lights/ Sunlight and Auto exposure? Or a Video about Lighting in general would be helpful. Can you share the link for the video if there is one already? Thank you.

nvangamudi, Theres a section in our blogpost https://enscape3d.com/architecural-rendering-glossary/ about Auto Exposure. That might explain it for you.
