If you are using vray and sometimes find that when using a vray dome light as a light source you get pixelated reflections of the sky, try this:
Select your light and type the following in the MaxScript listener:
$.dome_visibleOriginal=2
That comes from Vlado on the chaosgroup forum, he goes on to explain:
It just controls when the dome texture will be evaluated fully and when the values will be taken from the pre-sampled version specified by the “resolution” parameter. The presampled version is calculated faster, but is jagged. A value of 0 means that the pre-sampled version is used always; a value of 1 means that the presampled version is used for GI and glossy rays, and a value of 2 means that the presampled version is used only for GI rays. 2 should probably be the default, now that we have it.
I have never really noticed it, because the places it might show up (architectural glazing for example) I usually dont use glossy reflections. When I say glossy reflections, I mean any vray material with a glossy reflection value of less than 1.
Here is an example of the problem:
and fixed with the secret maxscript code:
Hope that’s useful to someone!

It’s not what you know, it’s who you know! Good stuff Peter.
Great tip! Probably better making it default
Noted, thanks Peter!!
thx Peter for sharing this secret code
You are awesome! Thanks!
Many thanks Peter, very useful tip!!
Thanx, really great stuff.
i’ve already suffered with this!
Thank you very much
I come across this problem frequently, thanks for the tip.. Awesome!
“.. I usually dont use glossy reflections. When I say glossy reflections, I mean any vray material with a glossy reflection value of less than 1.”
are you sure? what else do you use? I mean, glossy reflections are essential and it is working in vray compared to mental ray.
@florian like I said, in the places where this phenomenon might show up, architectural glazing for example, I don’t use glossy reflections. For arch glazing I use a glossiness value of 1.
I have a problem when i use the script it gives me this error message (– Unable to convert: 2 to type: Boolean) what to do ?
did you make sure you had a vraylight selected when you ran the script?
yeah i have tried different lights as dome sphere and plane but still the same error accured
I’m getting the same issue as Jasper, although it’s only just started happening. I’ve hard it work before now
