lighting problems or gi?

[Martina82]

Hello everyone!I am new to the forum and I hope you can help me.
I have been working with revit for two years.. and have passed from 2009 to 2011.. find remarkable movements from the point of view of the graphic rendering and rendering. but I have a problem that I had before. .that is, I noticed bubbles (to tell us) in the shadows and surfaces..more clear...in the rendering set with daylight and artificial...it was suggested that it is a scarcity linked to the few samples of the gi...but sincerely I do not know what parameters I could change...I have already activated in the window to make in which I choose the quality - personal settings - the voice that specific natural light filters from the windows...and have fallen a lot. but not enough. . .suggestions? Has anyone had the same problem? I attach image to understand. .
thanks for the help!

What does that mean? image management?
if so, there are discussions about the forum: use the "search" button on the top right in the revit forum ....

I think it means global illumination.... try to raise the number of rebounds of indirect light

thanks for the answers...I meant global illumination...however I managed to solve with the parameters within the customization of the quality of rendering! thank you very much... :

Excuse me............ you could explain yourself better!
but how do you eliminate "sfumature" from the suprtphs during rendering-internal sun and artificial light-?

if I rise (starting from optimal) the value of indirect lighting bounces, after hours......and hours the sumatures remain.

If you point out options enter daylight,.... hello the render no longer comes out.
the image is an interior whose resolution is 2000 x 1500 to 300 dpi .
I miss something

hi! then...premitting that in part the speed of performance of the render depends on the processor and the machine you have... I had the problem that created super bubbles on the surfaces.. and eventually I solved it like this:
-in the rendering parameters dialog box, you can choose the quality of the processed; by clicking on the drop-down menu relative draft...bass etc.. you can select edit.. and you open another window: optimal or high selections..(I selected the latter) and I put copy in staff. and there I went to change the parameters relative to the precision blurred reflections increasing it to the maximum;
- then down I selected active soft shadows;
- then option entered daylight..that from me was windows. . .

Actually in the parameters you have to play until you get good results. . .
maybe you should give an eye to the guide that clearly explains all the voices and what changes by changing the values...(http://docs.autodesk.com/subscripti...73099cc142f48755-42d82bfb116e746d5a6-4a9c.htm)

and one last thing: 2000 for 1500 being in mm...it is 2 meters for 1.5...cmq would take a lot...you know... be careful about the size of the rendering window. .

I hope I've been helpful. .

2000x1500 are pixels, about the size of a digital photo.
in high quality with the entrances of the light and all the lights off, i.e. internal only sun, it takes me four hours. If I turn on the lights.... pass the desire.
I will try to understand better on the site.
Thank you
