Hi guys, any idea what settings I need to change to get rid of these spots? Scene is lit by a HDRI environment.
Re: Scene “spots” problem
It helps if you take a screen shot of your render settings. We need to know what your using.
Re: Scene “spots” problem
I might trying increasing the subdivisions of the materials that are causing the problems. Also…are you using an HDRI? If so, check this thread. http://forum.asgvis.com/index.php?topic=6191.0
Re: Scene “spots” problem
aclark, yes Im using an HDRI and if you look I actually started that old thread, lol!
So I guess they never sorted the problem out for the new rollout of this version of vray, unless someone can see something wrong with my settings.
Re: Scene “spots” problem
What kind of HDRI map do you use. A lightprobe or a regular environment HDRI?
When using HDRI for lighting it’s best to reduce the size of the HDRI image and blur it quite a bit. If not, then you’ll quite likely end up with lots of artefacts.
Re: Scene “spots” problem
Its an evironment HDRI, commercially sold by “hyperfocal”. I have reduced the size of the hdri to practically nothing and also blurred it.
Not sure if using someone elses HDRIs would solve this or not as I dont have any others.
Re: Scene “spots” problem
Ok problem sorted for now, thanks guys topic can be closed.
Re: Scene “spots” problem
How was it sorted?
Re: Scene “spots” problem
Oops sorry, I was broken away from my computer when I was typing that last reply for some reason I thought I’d mentioned it. I took the HDRI lighting file into photoshop and applied yet another gaussian blur to it (4 pixels was enough) and now it works fine.
The actual file size of the lighting is tiny now! But I am happy with the results. Just out of interest thomthom could you cast your eye over my settings and see if anything you would do differently I would appreciate it when you have time.
Re: Scene “spots” problem
Settings looks ok.
Do you have an octa-core? Asking because I saw you had 8 LC passes.
Re: Scene “spots” problem
Hi guys, i had a similar problem with spots
I used sunlight with Evermotion hdri. Sometimes appear one or more lightinig spots (very brilliant). Is this because my hdri? Specially when i use refracted glass
Best regards
Re: Scene “spots” problem
I have an i7 which uses 8 threads. Hoping to get one of the newer ones with 12 threads soon.
Re: Scene “spots” problem
I was wondering if really each thread uses the 2.6 Ghz(or whatever you bought) ?
so with i7 you get 2.6 Ghz x 8
Whereas quad uses 2.6 x4
Right?
Re: Scene “spots” problem
As mentioned earlier in the thread, HDRI for light sources needs to be reduced significantly in size and blurred.
Re: Scene “spots” problem
Yes thats right, and the new i7980x has 12 usable threads, very nice but pricey!
Re: Scene “spots” problem
Thats a LOT of power for one machine 8)
Re: Scene “spots” problem
There’s a group in Texas called Boxx. I bought a machince last year that is the i7-965 quad core (8 virtual cores which equals 8 buckets when rendering). The i7-965 is the one you can overclock and Boxx overclocks this 3.20GHz CPU to 4.0 in the factory and warranties it. It requires a pretty good power supply and liquid cooling but you can barely hear it when it’s rendering.
It’s a beast, I love my compy. Call it a bump, but I would definitely recommend these guys for anyone looking for a render machine.
Re: Scene “spots” problem
They are nice machines Omega, but I built my own same spec machine for less than they sell them for by sourcing the components myself.
Re: Scene “spots” problem
will asgvis plan to render using gpu’s? or will they continue using cpu for rendering?
I also built my own spec. though it is only core i5 
hehe
