A little paradise

Very nice paradise. It looks detailed enough to be rendered much larger.

@GussNemo thank you, I’ve been working with objects and single light sources trying to become more famliar with the Bryce lighting system.

@Horo raydepth is 128 premium render 64rpp soft shadows turned on.

I’ve noticed some odd behavior with lights and shadows that seems to occur if you turn off abience in sky-fog, that looks like objects don’t cast shadows anymore.

Here with Ambience turned off followd by ambience on

Rareth, the global ambiance control (on the sky & fog shelf) also doubles as a control for the shadow intensity.  So switching off the ambiance control as you put it, effectively switches off global shadow casting for all direct light sources.  The controls this control relates to are seen in the first tab of the sky lab.  You will find a colour swatch for ambiance (global) and a shadow intensity control under the sun (above soft shadows) although this control is under the sun it is in fact the global control for all direct lighting shadow intensities - harking back to simpler times when the Bryce sun was usually the only light source in a scene.

In the mean time, not getting on with any useful work myself, I’ve been lured into exotic lighting experiments.  Or rather obscure lighting experiments.  I hereby dub these, “obscure lights”.  Since I am fairly confident that this is the first time this approach as been taken, I will invent a name for them.  They are an extension of “gel lights”.  Which in turn are an extension of the TA optimised lighting system added by our man Vasily at the behest of the Steering Committee.  They also take advantage of “Light from Inside HDRI feature” which is about as obscure as it is possible to get in term of Bryce lighting - hence the name.

Be warned, you need to be a pretty big fan of listing to me wibble on about lighting and watching me noodle around in Bryce to get anything from the video.

Len - I offer you no choice in the matter (but of course you do have a choice, I’m just not offering you one), you’ve got to watch this video - it should be of special interest to you.  Since it is a means by which very good global light simulation can be achieved in Bryce within decidedly tricky lighting environments.

ok that makes sense, will play around with it some more, thanks for the explaination

A slightly more interesting subject rendered with obscure light.

Thank´s. I have a big problem with this picture. If i try to fill the terrain in the background with grass or other things (with the instancelab) Bryce crash. Sometime Bryce crash if i try to load the scene.

I have a new PC. Intel I5 2500 K - 8 GB Memory - NVIDIA GTX 550 TI with 3 GB memory - win 7 64 bit

What is the problem ?

The problem is that Bryce is a 32bit app and as that restricted to 2GB of Memory.
You can make it Large adress aware to use 3GB :

Hi,

I am lately rendering in Bryce 7 Pro again.
The render I post here is all Bryce except the terrains (GeoControl) and the person (own photowork).
You’ll find more work in the Renderosity Bryce gallery.
Comments are always welcome.

Kind regards.

Thank´s. I have try it and it seems that it’s better now, but it look´s not good with the grass. The picture look´s better if i take the premium effect with soft shadow and depth of field and higher Rays per pixel (64) + light boost without fog.

That looks incredible

more playing around with Bryce, with some DAZ imports thrown in.

Here’s the how to without the theory Bryce 5 minute lighting project - how to set up “obscure” lighting - a tutorial by David Brinnen Five minutes of your time… and some more of your CPU’s is all you require.  Bearing in mind that you already have a version of the HDRI shown in your content supplied by Horo that you got with Bryce 7.1 Pro!  Know your content?  Bryce Content PDF by Horo

@eireann:  That’s a real neat looking image.  Reminds me of the rifling inside a gun barrel.

@Roland:  Little Paradise is very nice, though I think the bars are more distinguishable in the first image than the others.  I don’t see bars in the other images, just black lines.  Perhaps adjusting the color, adding a bit of blue will give them a more bar look.  Or lightening the background color.  Still, all of them look great.

@David:  Anyone whose watch any number of your tutorials are used to your wibbling and noodling.  It’s part of the reason they are good.  I’ll have to watch your two new videos when I’ve time because the newest images are marvelous.

Friends on another site I frequent, suggested I put my pumpkins on a set of steps.  I’m sure they had house steps in mind, which I didn’t think would look good sitting by themselves.  These type steps would look great against the side of a house, with a door and maybe side windows.  Something for another time.

Instead, I decided the steps would be as you see in this image.  An expanded, and flattened cube, cylinders to cut the cove, and cylinders to cut the flutes.  I first tried to use HDRI lighting, but realized I didn’t know enough about setting it up to produce something acceptable.  I’ll have to go back over the HDRI tutorials.  So I stayed with TA lighting, a fiddled with wood texture on the infinite plain, and on the shelves and spindles.

As usual, comments and suggestions are gladly welcomed.  By the way, in checking this post after submission, I saw the image can be enlarged and looks so much better.

A secret place.
