Bobby,

She mentioned using it to convert images directly to .hdr - in that blog.

Rosemaryr,

What size are the images you made?

Come to that, how the heck did you make that bendy multicoloured image?

D'oh...musta been the colours on the page (excuses excuses) LOL.. ...

Hi Rosemaryr, I took a look at that yesterday and was put off by it's technicallity LOL. I use the right side of my brain incidently :blink: so I need more practical on hands use like put A here and put B there. I really am thick when it comes to tecnical stuff, I usually just guess and stumble on something new with Bryce. :biggrin: I do watch Start Trek regualarly though, but it don't help none. 

INTERESTING POST! :)
I wil try some experiment!

Oh....okay.  Let's try to address some of these responses.

Fran....The initial renders were larger....for my test renders I run around 600x600 or 800x800.  I kept the images small to keep the blog entry fairly light weight.  I can post some of them here if you want ....I can show a few more (larger) renders here if people want.
As for making the initial "bendy multi-colored image"..I started with a square-aspect new image in Photoshop.  Made straight-edged selections (use the 'shift' key to confine the selection to pure vertical, horizontal, or 45-degree lines) to make the triangle shapes, filled them with the colors, then circular selections to cut the white and black in.....Quicker to do than to explain it. grin

Dhama.....if you want I'll post some test .hdr images for you.... Here is the steps:
Step 1) Save the .hdr files somewhere on your computer where you can find them again.
Step 2)  Create a basic scene... Add some primitives, color them flat white (the better to see the effects)
Step 3) Kill the sun and any or all lights.
Step 4) Enter the HDRI/IBL section of the Sky Lab. Click on "Use HDRI image" and locate where the file was stored in Step1.
Step 5) Set the following settings: (adjust later as needed)
             Quality: 256 (about halfway on the slider)
             Intensity: 5-15  (as needed)
             HDRI Effect:  100 (percent)
Step 6) Render.
Step 7) Experiment....

Jeez...now i really want Bryce6..ah...the lot of the impoverished Mod....LOL.....someday soon.. ...

ps. "nudity" flag for just in case...she does wear sufficient clothes, but don't want the mods to get annoyed  grin

(Clicky on piccie for even larger version)

I have prepared a zip file of various hdri images, mostly based on gradients, but also including the "Multi-colored box" used in one of the above examples.  Anyone who would like to experiment with them, just drop me a line....either through a IM here, or by email....and I will email the zip file to you.
The zip file is ~480 Kb, if that makes any difference.

No boobs[nipples covered] or pubes...you're O K ....LOL.. ...

aaah, gee, Bobby!  Didn't that just annoy you???  ROFL

**@Rosemaryr....why not post it in Bryce Free Stuff...you have a captive Free Stuff Mod here[me] who could approve it nearly instantly.....
**

Rosemaryr,

YES!!!!  Pulease!!!!

(I couldn't make one myself even with your explanation, I guess I'm like dhama, I need the 'put a here then put b there' type of explanation)

Fran - jumping up and down frantically.

Quote - And for a more 'real-world' application, I used my test Poser subject, called "Red" (for obvious reasons grin).... This shows how it affects skin tones.  I used a simple linear gradient (shown in the inset box on the lower left.... blue for sky, and pink-red for earth).  Same method as described above in my notes to dhama..No other sunlight or other lights here...just the hdri image.

ps. "nudity" flag for just in case...she does wear sufficient clothes, but don't want the mods to get annoyed  grin

You call that nudity??!!?? Heck, that rates an easy G or PG-13 rating.... LOL... I ain't the mod but I was ROFLMBO...

ou call that nudity??!!?? Heck, that rates an easy G or PG-13 rating.... LOL... I ain't the mod but I was ROFLMBO...

Well, call me a bit old-fashioned, I guess.  While I do enjoy the beauties of the male and female human form as an artist, in real-life, I would blush if I ever encountered "Red" on the street!!  LOL!

Fran, bobby...I'll see what I can do to post it in FreeStuff.... that'll be a New Thing for me.

Okay, I have navigated the FreeStuff uploading, so now it's a matter of approval....I'll let you guys know when.

As for playing with these, one way of 'seeing' the effects of it, is to make the camera the "parent" of every object in your scene, then rotate the camera on the World z-axis.  This allows a view of all the various color gradations effecting the objects.

All done...they're now available in Free Stuff.. ...

Er... Bobby,

Rosemaryr,

something's not working there, I'm getting this error message when I try downloading:
Sorry,

Rosemaryr, I tried going further back, by cutting off all but:
http://www.rosemaryr.com - but there seems to be no other route to it that way, so... Help???

Trying to rush it too much; leads to error, leads to confusion.  Again, my bad!

I'm also working on making some others.  So keep your eyes peeled for more test renders, and more freebies.

Worked fine for me but it may have been fixed before I just tried it...works fine from the Free Stuff page as well now.. ...

That's better....

Didn't know how to make one but figured out how to adjust one pretty quickly.

With this as the Hdr:

Gonna see what happens when I rotate the hdr's 90 degrees next... I'm having so much fun with this, I can't thank you enough Rosemaryr, for coming up with this...

Oh, I am sooo envious of this ability....some day soon.. ...

My brain thanks you Rosemaryr. :thumbupboth:

I will test it out on some of my Landscapes.

I find it absolutely fascinating that a simple change like rotating the image can make such a difference to the scene's colours.

Fran, if you do a search on the net there are a fair number of HRDIs out there to play with. Although I don't have Bryce 6, we over in the Imagine forum tho not having true HDRI capabilities have a user who wrote a script that uses the light gen plugin to freate arrays of light based on the image that very closely approximates HDRI renders so I obviously went out and found bunches of em. Sorry now I didn't save the links but I got em with Google so you can too.. ...

I'm working on one that will imitate fire-light at night with random candles.... Sure, it could be done with actual lights in the scene, but this way you don't have to actually have them, which will increase render speeds, especially if the candles and fire aren't visible in the view.   You can get the effects without the cost of the lights.

I'm also working on some to imitate sunlight in a dense forest....and other natural lighting of that sort.

As an OT, concerning lighting and color, I was just pointed to this site:
http://photo.net/photodb/member-photos?user_id=2231437&include=all
This guy really understands lighting!

This is kinda what I hope to achieve with this.

Hoooeee...mucho gracias for that ...I've sent the link to my whole address book.. ...

I was just intrigued by the thought of using images that aren't scenic, as hdr's.

I believe Agent Smith (our Kirk) did a few experiments into this, but I guess I just wasn't enough up to speed with B6 at the time to follow much of what he was saying, anyway I think he only used 1 non scenic hdr image and that was black and white. 

Doesn't have quite the same appeal to the child in me, as all these colours do.

I'm now experimenting with red and green hdr's, and sometimes adjusting the sunlight, with or without, direction, colour, etc

Fascinating....

I've also tested out changing the amount and position of the red and the green and the strength of the colour, the strength of colour it seems doesn't make a lot of difference, since you can adjust that in Bryce's IBL via Intensity and HDRI Effect - or you can adjust it in HDRShop  via Gamma Curve.

Area "1" will be directly in 'front' of the default scene.
Area "2" will condense to an area similar in size to area 1, but 'behind' your scene.
Area "3" will be 'overhead', and area "4" will be underneath.
Areas "5" and "6" to either side.

By using these, you can pre-plan where your major lighting effects will come from: 
Do you want 'noon-time sunlight'? Put a yellowish light in area 3.  Windows or doorways would be in 1, 2, 5, or 6. 
Lighting from the spooky dungeon...from below, in area 4.

This will also help you anticipate the major lighting from hdri's you find out on the web, as well.

Cheers.

Brilliant work Rosemary...I'da never thunk that out in a ba-zillion years...thanks...really.. ...

Thanks Rosemaryr,

That's exactly what I was beginning to wonder about.

If it wasn't 20 to 4 in the morning here - I'd try that out.

yawn, night night.

Actually, I do have an addendum to make about the 'layout' hdri image.
I said originally, that this is how it would look at the 'Default' camera position...but it turns out you actually have to set the camera to 0-0-0 rotation, and position, (in the attributes menu) to see 'area 1' directly in front.   My error in the original post.

Ah so what effect does it have on the Director's viewpoint?  I never use anything else.

Tried what you posted, but with the camera at 0,0,0, position and 0,0,0, rotation all I see is this:
(top image)
which isn't too surprising when you see where 0,0,0, & 0,0,0, puts the camera (bottom image).

So for me, that doesn't work.

For these, I've been mostly using the 'Camera' view.  But that was mostly because I linked the scene's objects to the camera, in order to keep them in position as I rotated the camera, so I could 'see' the different areas of the background render.

If you are happier/work easier with rotating the hdri image's colors, then do what's best for your working style. 

Experimentation is at the heart of all this, and I certainly don't claim to be the end-of-the-line authority on it all!  grin

Awwwau!  I thought you'd come up with this brilliant solution to easily figure out what colour does what, where, to what!  Now you go tell me you're fallible.

shakes head sadly

Lol!

I certainly think you've managed to wrap your head around this subject somewhat better than I've managed so far, so no running away just when it's getting interesting.

raises admonitory finger at you

and tries to look as scholarly as possible

fails miserably

ROFL!

Hey Rosemaryr, have you got any further with this?

What about the firelight effect?
Ditto candles?

Oh, and you said you were going to have some more freebies???

I like freebies.

I was also just wondering if anyone wanted to try out any of my rainbow.hdr's?

What about the dense forest sunlight you were trying out?  Did that work?

Can we see your trials on it?  Pretty please?

I'd really love to know how you'd even start with that!

Would you have to put lots of trees in a scene first?
Cos that'll slow down a render right from the start!

Please, please let us in on all the secret trials?

I mean the end results are great, but the trials would be so much more informative!

Heh.... been a bit busy in real-life....
I promise to get back to this Monday morning, when I get home from work.... (...night-shift... blehhhhh... plays havoc with my sleep cycle!)

Goody goody,

*rubs hands gleefully...
