I have an array lamp set facing up a, moved down a bit so it will give a glow on the top edges. But no matter how big I make the number it won't make it brighter. I can't move it any higher up or else the camera will see a dark spot under the light. How can I fix this, and is there a better way to light it? Im using cycles.

    $\begingroup$ Are you using any clamping for direct light in the render settings? i.sstatic.net/Em7QF.png $\endgroup$

  • $\begingroup$ @susu direct clamping is set to 0, direct set to 2. $\endgroup$

    $\begingroup$ That is the issue right there. When you clamp direct light to 2, then you are limiting how bright lights can be, it doesn't matter if you set the intensiti to two million, values past 2 will be clipped. If you are using filmic, 2 is not white, but a light gray. read: what is clamp direct/indirect $\endgroup$

    $\begingroup$ Does this answer your question? Emissive shader does not change much in changes of orders of magnitudes and emission shader does not bring enough light $\endgroup$

Setting it to 1 MW seems to work.

    $\begingroup$ I bet it does! You'd need a nuclear reactor to power that lamp! :D $\endgroup$ Commented Jan 8, 2021 at 21:17
