Anyone Have Tis Problem ?

I have problem with some glowing parts of body when touching other mesh surface. Figure doesn't matter, it's the same with V4 or G2.
Here is the image with the problem.

I was using 3 light:
Distant light
Spot light
Advance Ambient Light (tried using UberEnvironment and have the same effect)

I have tried to change the light angle and camera, but the problem persist.

It looks like shadow bias is too high. Look at each light in the scene in the Parameters tab and see if it has a shadow bias setting. If so, reduce it to something like 0.1 for starters and see if that improves or eliminates the problem. Adjust until you get acceptable results.

Jaderail

Ambient Bounce light, as the item is CLOSE to another item the Bounce light is more concentrated on those areas. As noted above Shadow settings and the Ambient settings together can fix the issue.

Thank you barbult and Jaderail, I will try the shadow bias setting, since I already turn off all ambient color / strength.

It seems that shadow bias setting and ambient setting lowered the glowing light, but I can't completly remove the glowing except make the figure not touching any other mesh at all.

Jaderail

Well believe it or dont but that really happens in real life as well, it's just more noticeable in 3D renders.

I see, but it's a bad thing, our eyes seems attract to the brightest of the image. Guess I'll need to play the lighting more

I am having the same problem. It seems like it only happens when I use the advanced ambient light. If the scene is well lit, you don't notice the problem. I noticed it in a scene where the figures feet were in shadow. In that instance here toes look like little beacons in the night. Not the look I was going for.
I can probably fix it in post but I would like to not have to do that. I will continue to fiddle with settings.

I test another render last night with UberEnvironment, and produce the same problem, it seems doesn't matter what the lighting is as Jaderail said, it is the law of bounce light ^^

The only way to fix this is by give a little space between object so it won't have object collision. I know then it would looks strange like floating but thats the only way I can fix it right now. It will be nice to hear another suggestion.

Just in case anyone still looking for a solution to this problem.
Try this,

Add another primitive like plane, or cube, make them a layer beneath the glowing surface.

Ex:
If the glowing parts are on the floor, then add a layer beneath the floor and give a little space between the floor and the layer (you can use plane, cube, etc)
