A strange dark dot on the HDR screen

[AlexBBM]

Hello. A strange dark dot on the HDR screen. Appears in the falloff mode Quadratic.

I'm not sure, but I would check the part/mesh just turning along its axis to see if the dark area still exists. And perhaps a normal recalculation or re-import with higher tesselation or maybe NURBS mode should change the result.


Hope that helps

Thx for answer. Tesselation 0.5, render like NURBS, axial rotation... nothing helped

[AlexBBM]

If falloff is changed to linear or exponential, then a bright point appears in the given place, as it should be.

Could you share the environment file (hdr or hdz) to replicate this effect?


I guess it must be in the environment settings (size, height, pins).


Or could be in the mesh. What modelling tool was used?

[AlexBBM]

Model SolidWorks

The problem depends on the fall off mode of both (side) pins. I changed the fall off to "from edge" and changed the fall off value to 0.5 as similar to your example.


Hope that helpes

Is it a bug of quadratic mode?

Hi Alex,

Yes it is a bug in the quadratic falloff mode. Thank you for reporting it.

It has been fixed in KeyShot 8.

Hmm. But I have one question: Why do you use the quadratic fall off?

Just for expirience.
