Pseudo Color Exposure (LUX)

Post by JuandeLara » Wed Oct 28, 2020 8:22 pm

Hello all,

Do you know if there is any option in LuxCoreRender to do a Pseudo Colour Exposure that measures the lux on the surfaces of a scene?

Like in here?

Thank you. I actually Found it under scene, color management, false colour.

This scale varies if I modify the exposure. If I leave the exposure at 1, I still get a blue color for the lux of the sun which usually translates as 250 lux which is not enough for direct sun lux. What am I doing wrong here?

Your screenshot is super tiny.
But it appears you are using some false-color mode built into Blender. I don't know how that behaves, but it's not what Dade meant.

Also, make sure to set the sun and sky gain to 1 for your use case.
