first attempt - a few questions

[dynaman]

Hi all,

 

First of all, greetings as this is my first post in these forums. Lots of talented artists out there!

I have just started using vray (I'm a late bloomer from scanline...) and have tried re-working one of my old scenes. A nice small bathroom with minimal polys and light sources.

In general, I like what I'm seeing, but I do have a one question about some persistent areas that are giving me grief. In particular, I get a splotchy, light bleeding effect around the edges of the light panel in the ceiling and the window in the wall. What's strange is that I actually get better looking results when rendering with a "very low" setting on the irradiance map (see the two images attached). I'm guessing this is really only due to blurring on the very low setting, but nevertheless, I don't know how to get rid of this blotchiness when rendering at higher settings.

Other than that, I'm pretty happy with the progress. I think there's probably too much noise on the ceiling, and render times are slower than I'm used to, but I'm having fun learning this new tool.

Any suggestions to fix this light problem as well as other C&C are welcome.

 

Thanks!

I'm not sure what to do to fix it, but are you trying to tell me that you can have a scene with that many reflective materials and that quality of light render in 8 mins in scanline? I'm calling your bluff. Me, I would go with the lower irr setting. In fact I often plan on using the lowest setting I can unless I need the shading detail of a higher preset.

scanline, sure. attached is the original project done in scanline. i don't remember exactly how long it took at 800x800, but it was definitely not more than 4 minutes. lighting quality isn't quite the same (or why use vray?), but that's also partly due to client direction.

i have noticed that the lower IR settings sometimes will produce satisfactory results, especially depending on the materials in the scene. anyway, i still think there must be a way to fix those light blotches...
