spotlight in 3ds max with Arnold

[swechachhap0608]

Spotlight stopped working in 3ds Max even after giving adjusting intensity and exposuer . I'm using 3ds max 2022.

not getting any difference in render . Render is Arnold.

Arnold will not work with standard lights. Use photometric lights or, better yet, use Arnold's own light object.

I'm using spot(light)from arnold only.

see the attachment.

The Radius of your light seems very low. Increase it to maybe 4. Normalize Energy should be deactivated.

If that does not help, then - assuming that nothing is blocking the light - there are other areas to check.

First, Exposure Control (Environment and Effects). Choose Physical Camera Exposure Control and a reasonable Global Exposure Value, maybe 6.0. If Use Physical Camera Controls If Available is active and there is such a camera in your scene, you must also check its settings. The Exposure/Exposure Gain Target value should match the Global Exposure Value you've set before. Check also ISO, Aperture and Shutter values, even if Target is active. Sometimes, by unknown reason, ISO is set to 0.0.

...and finally: Both Color and Filter Color of the light should be white except you want a colorized illumination.
