remove dot effect from renders

[geomap]

hello to all I pose my problem....I make mental ray in ambient/reflective occlusion, in practice when I make the image is not beautiful sharp but has a annoying dot especially in the shadow zones... help me step by step to understand how to remove this disorder? is the second day that one this program....so excuse me x the terms I used do not even know if I said qlke caxxiata ps the verse I use and the 9

What if I'm in a closed environment? without windows

What if I'm in a closed environment? without windows

if you are in a closed environment the dot is given by light photons of light sources (quantity, size, intensity, distribution and interaction).
you need to correctly set these parameters according to the scale in which you designed, at the nr of lights present in the scene and materials especially reflective ones.
There is no rule, so you have to figure it out on your own.

and there is no guide or similar that can explain to me a little these things?
type where to set these parameters? in the properties? and I guess I'll have to raise them to make the dot disappear

Anyway thank you for telling me what it depends on:smile:

1. the guide goes according to the rendering engine you use (v-ray, i-ray, mental ray, arnold, scanline, etc...)
2. then there is to understand whether you are using standard lights or photometrics, however the settings of the lights find them in the editing panel of the lights themselves
3. I don't remember if you have to increase or decrease, you have to do tests by changing a parameter at a time
4. Please.
