PW2 weird dots in rendering

PW2 weird dots in rendering

PW2 weird dots in rendering

(OP)
Maybe this has been addressed before, but I get weird dots on the mirror surface of my object.  I tried all different kinds of settings (indirect illumination, anti-aliasing, raytrace, anything) , but the dots keep appearing. I have no clue what this could be...:( The upper part is plain glass as material, the metal part has a mirror as material. Rendered this in PW2, modelled in SW'03, opened in SW'04.

FYI, I am two days into SW'04 and PW2, pretty amazed by the quality of PW2, but it is darn slow.

I take any suggestions...

RE: PW2 weird dots in rendering

The dots were a bug in PW2 when using Indirect Illumination.  I think this problem was sloved in SW2005 PW2 using a seperate setting for the Indirect Illumination radius.  If your on 2004 there is a work around.  In the Scene Editor you want to go in to the room tab.  Next set your length and width setting for your room to a very large size in relationship to the object your rendering(example I render a 15ft x 15ft object I set the room size to 500 ft x 500ft).  This should remove the dots.  If not keep increasing the room size until they go away.

PW2 does produce a much higher quality rendering than PW1.  The high quality does come with a decrease in speed.  The single biggest factors on speed in PW2 are the anti-alias settings, Indirect Illumination setting and the shadow quality settings.  I start my rendering with these settings in the low position.  As I work through the material application, scene and lighting adjustments I increase the settings to a higher position incrementally.  I use the higher setting for the final render only.

Simple and effective answer, no more dots. Thank you rockguy.
..but, don't want sound like a whiner, but the picture got a lot duller and less interesting to look at. Especially around the legs the shadow is much lesser.


Can I admire ur render work on a webpage or other forums? I always am on the look out for nice renderings and render tips. Modelling is half the fun, the other half is to get the rendering as close as possible to the desired reality.

RE: PW2 weird dots in rendering

Unfortunately I don't have a web page.   I do have lots of renderings though.  I have been thinking about setting up a page showing PhotoWorks renderings but haven't taken the time.  I agree, modeling is only half the fun.

The indirect illumination is diminishing your shadows and  things may seem dull because your moving the reflective wall surfaces of your room further from the object.  The only help I can offer here is to adjust your lighting or material settings slightly to make up for the larger room size.  You might also try lowering your room ceiling closer the the object.

SW2005 has also fixed this bug and lets you control the indirect illumination seperate from the room size.  This allows you to lose the dots and keep the deep color reflections.
