# Glare Node not act as Expected

Do not understand why Only 1 part of my Emission Tube glow via Glare node in Compositing Tab. Thanks in advance.

The glare node works based on a threshold value. Meaning only the pixels that have values larger than the set value will be affected by glare/bloom/glow.

Use a lower value until you get what you need.

Also, keep the mix at $$0$$. If you set it to $$-1$$ you are actually cancelling the effect completely.

Mix

Value to control how much of the effect is added on to the image. A value of -1 would give just the original image, $$0$$ gives a $$50/50$$ mix, and $$1$$ gives just the effect.

Threshold

Pixels brighter than this value will be affected by the glare filter.
