THE PLACE FOR ALL THINGS BRYCE - GOT A PROBLEM? YOU'VE COME TO THE RIGHT PLACE


Subject: True ambience comparison

I used a white 90% ambient 10% reflective sphere, same mat on floor plane, 1 std spotlight with 25% edge. Sunlight disabled. I wanted to see what True ambience would do in and of itself to a standard scene file. Thought others might like to see the results too.

And for those of you who have used that lamp, I deleted all the radial lights so they wouldn't interfere.

Pretty cool! thanks. Are you saying the scene is inside the sphere?

Try adjusting the .jpg to compress at 'best quality'. The jpeg artifacting on this detracts from the high quaility of the scene.

I couldn't remember what the size constraints were on forum images so I went a bit further into the compression than I normally do. high quality - Really!? LOL! Thanks though! I'm not making any fun of you TB, I had just dropped in the three freebie objects, positioned them, added the light and made the sphere shell/mat setup and go. Approx 10 minutes total. To me it was just a throw away test. It is an interesting technique in certain instances but the render time penalty is way out of line (extrapolate to a 1280x1024 and you will see what I mean) for most of my work. I will probably use it again though.

Treemont, Yup! dead centre. May experiment with offsets (interesting idea)

Incarnadine: The chair looks really good in the 2nd pic. I figured you were testing a lighting set-up. This looks like the beginnings of one of those 'true ambience' pics and as such would have 'high quality', the kind that looks very impressive. I am constantly ammazed by these t.a. renders as I cannot even come close to them. The size I think is 200kb and 800x600size. I find that jpeg artifacting is pretty fickle stuff. Some of my pics come up alright on the Rend but others simply look awful...there's the breaks....

Bryster- If the limit is indeed 200K (pretty hefty, most of my posts in the gallery are in that range!) I certainy could have put the originals in here (LOL!) As to jpeg artifacting, I use PhotoPaint 9 for all my postwork and have rather good control/preview functions in that regard. What are you using?

Incarnadine: I use PSP7 to convert my Bryce .BMPs to .JPG. I have set the quality/compression to 'Best' but I don't always get the best pic. They usually look great on my monitor but can look poor on the REND.

Hi Just a thorght TB I sometimes use PSP7 but I found not to trust the "Image Information" from the pull downs they always give miles bigger file sizes than they really are (checking saved files against those loaded values) so perhaps you could get away with less compression and still keep the file size down. I may be wrong but it's just an idea. Dave

Is any light coming from the sphere? This looks mighty cool, but would crash my little k62-400mhz machine in a heartbeat. I should say that it would crash Bryce on my machine.

Wanderer: You're quite right! I always read the picture files size in the directory, not off the PSP7 screen toolbar. I also tend to balance the size of the image(kb)against the probable download time for the REND. I would use bmps instead if it wasn't for their horrendous size. The Bryster

Just a word...Internet resolution has been updated to 96dpi instead of the 72dpi which has been standard all along. This is due to higher resolution video cards and monitors. Most folks have set their screen resolutions to 1024x768 and higher. Try outputting to 96dpi in Bryce to get some fairly sharp and clean cut images. But be careful with output bytes which are still heavy and play havoc on deal-up modems still largely used. Long download times turn viewers off to the point of not wanting to wait around for the picture to fully materialize, thus, many a good image goes un-noticed.

Nice one, Quest! I didn't know that! But 'outputting to 96dpi in Bryce' is something I'm not familier with...... Thanks!

Yup! I think I've got it....go to page setup, this allows you to customize the resolution. Many thanks.

So as not to hi-jack this thread, which we've probably done anyway, I've started a new one......entitled Jpeg Artifacts...tell me what YOU think!

To change the dpi in Bryce, you must render to disk and manually change the dpi. Go File--->render to disk...--->enter dpi in print resolution. Because the pixels are packed closer together for the printing option, means a cleaner rendition even when you optimize for file size.

Sorry, I moved my post down when I tried to add to it so it seems your post is out of wack TheBryster, many apologies on my part.

Groingrinder- all the sphere is is a jacked white ambience to 90%. Zero transparency and sunlight disabled. The only light is a down directional spot on the three objects. What I had wanted to see was what the true ambience effects would 1) do for me imagewise and 2) cost me, render-time wise.
