You could see the burning area...
Right, I have applied buffer_api...
I also know we could increase light cone, decrease the light intensity to get rid of this thing. However, are there anyway to setup a shader that control the intensity or exposure it gets.

You could use the tone mapping in Francescas Ctrl_Buffer shader, it's great for stuff like this.

You need to emit much more photons from your GI emitters. This will reduce such artifuckts.

No, this s just test and I dont care about artifact :).. I also use tonemap in buffer.api now... But I want more control to the exposure of the object, by controlling the shader

[Wish]

The best control of exposure is 32-bit non-quantize image and Shake at your hands

Yeah, I know how to control now with surface luminance

and use color 1 of blender node to control the exposure, a blacker color mean the less exposure you got

I got some misssunderstanding. You say, you control exposure from shading network?

Yeap
With this node connected, you could control how exposure on the surface is

Right. This is the same.
PS: As for me, I like multiply node between lum and texture more (or m.b. not lum. This is depends on the case).
