Thank you Dade for the fast reply,
but I guess i haven't expressed myself well, i know how to achieve that look with a point light, that's how i made the example in my first post.
The sphere was also just an example, in an actual scene you have alot of different light sources, but i want that ...

Fade out / smooth shadow terminator ?
Happy new year everyone :D
I want to know if its possible to blur or make the transition from shadow to lit area (i guess its called the shadow terminator ? ) more smooth, without changing anything in the scene(e.g. lights) except the shader.

Re: Weak Caustics with BiDir, Path Caustics ok
Yes, only BiDir was used.
Wooow, after I had checked everything again just to be sure... now i FOUND the real cause :lol: WTF, this bug is caused by the receiver , the ground geometry. Also the glossy material used only exagerrated the effect. :shock: Subdiving, cutting, adding edge loops ...

Re: Weak Caustics with BiDir, Path Caustics ok
IIRC, there's something wrong with HDRI rotation. At least last time i checked it was quite different than in Cycles. Gonna test now.
EDIT... looks fine, just intensity differs a bit, but was expected... sorry for the false alarm :roll:
EDIT2
I think Path caustics with small resolution (1k ...

Hello community,
sorry to bump this thread again, but i’ve downloaded the new BlendLux Version ( BlendLuxCore v2.0 )
And tried my old scene again (first post in this thread ), and noticed that the BiDir render-mode is still flawed.
Somehow the generated caustics in front and behind the sphere are ...

Weak Caustics with BiDir, Path Caustics ok
Hello Lux Community,
i have a problem with caustics and the Bidir rendermode, maybe you can help me out with it.
I cannot get a visible strong caustics effect with the bidir render mode and a hdri as lightsource.
I works fine with a sun light or spotlight, but i doesn't work with an hdri.
I know ...
