Its a low quality with proxies hidden version.

And i am facing a problem here with Vray caustics.
Caustics is only visible in reflections and not in refractions. any solution?

Using Vray sun with HDRI for lighting.

Attaching the images.

I have a problem with an interior scene and I do not know how to solve it. I attached a crop of the picture.
The scene is lit by a vray domelight with a hdri in it. And I get those light dots on my walls. I tried everthing I know to get rid of them but nothing worked. So I am happy for every hint!

Name: crop.jpg Views: 1034 Size: 164.4 KB

Scene setup:
Overall: Gamma 2.2
Scene light by vray dome light with hdri in it. Multiplier 1,0. Gamma of hdri 0.8. Subdivs 64
Color mapping: Reinhard; 1,0; 0,05; 2,2. Sub-pixel mapping, clamp output checked
Image sampler: Adaptive DMC; min subdivs:1; max subdivs:20; Clr Thresh: 0,002
GI: IR+LC
IR: min rate: -3; max rate: -1; HSph subdivs: 120; Interp. samples 60
LC: 1200 subdivs: retrace treshold checked
Camera: vray physical camera

The only way I get rid of them is when I check Store with irradiance map in the vray dome light.


I hope somebody can help me!
