Rendering with light problem

[Alejandro_66]

Hello everyone,
Can someone explain how come, on an exterior scene, lights dont render when using HDRI maps but do render with Environment Sketchup color set to Black?
Here's the scene to give you guys an idea.

Thank you,

Alejandro

What tone mapping are you using ?
The reason may be because the HDRI is so strong that it simply overpowers the lights. You could try increasing the emission scale of your lights.

Hello HR!
The environment is default to one. Emission scale is at 10000 lumens...
Lights seem to work well only when environment set at Sketchup Black...
Tried different settings but artificial lights + environment maps dont go well together...
I'm sure i'm doing something wrong.
Tutorial where are you??? )
Thanks HR!

It could still just be the light power... this is a known annoyance, but you may just have to try bigger and bigger values until it works... I've have lights at 10000000 lux in the past! It's normally a good idea to overpower the small light sources if anything, you can then turn their individual light layer power down inside Indigo. This can help some images clear up a bit quicker too, as Indigo is applying more of its resources to the smaller lights, which are often the source of a lot of noise.

Yep, just trial and error to massively overpower your lights. I've tried setting lumen values to manufacturers documentation value and the lights barely show up. Its not uncommon for me to have lights in my scene at 50,000 lumen just so they look right to me in the scene.

Probably something I'm doing wrong in setup, but I can work round it now.

Something that would also help is to create a more realistic scene.
Make the ground plane big enough to reduce the amount of light coming from below.

The default background is also not necessarily the best environment to start with for mixed lighting situation. Perhaps try to use a sun-sky environment with the sun almost down.
Or you could try to find an evening HDRI and use that just so you have a lower natural light environment.

Also don't use Reinhardt tone mapping but camera tone mapping.

Django Reinhardt tonemapping?
