The first picture shows the settings and the second image shows the result. I added an additional light source and placed it on the right side from the camera. Without the additional light source the glass is to dark.
@Jay: Darn, I didn't compliment you on your latest scene. Though I'm not to keen on the sky--as if I should talk. :lol:
@Roland: David has made a few videos covering making glass, and talks about the darkness of the glass.
The RW had me tied up for some time so I hadn't done any Brycing for a while. David's Space Invader Wings 3d tutorial gave me an idea and the image below is the results. I'd never tried this type image using just a star field, but it's not a bad start. Any comments or suggestions gladly welcomed.
Thanks GussNemo, but in the moment i can not look videos, bacause in moment i only have a usb internet stick with 5 GB / month. If i look video the stick is unusesable after one week. But i will have your tips in the mind.
Cheers, Guss...yeah, sky normal-ly...B O R I N G, and yacht, I guess, should be smaller - to scale-to-suit.
All I can suggest is LMB, Dodge, RB, slide/LB, then shoot-combine Dodge, and finally SPLODGE (note, all must be done within 0.003455 seconds, else, lost). And if that makes sense, you're a better player than I am ;-P
Jay
attempt number 2 at using wings 3D and following David's tutorial, it also gave me another great chance to use a bit more of David & Horo's metals pack :)
@Roland4- try setting the Quality to 16, Saturation to 100, intensity to about 10-20, Specularity to 0, and the HDRI effect to about 25-30 ...i hope this helps :)
@Tim Bateman
I have use your settings and this is the result. I have delete the additional light source. It is to dark.
@Jay: Don't you mean joystick left, button, joystick right, button button, repeat as often as necessary?:lol:
@Roland: I just watched part of a video about glass, try raising the Maximum Ray Depth (MRD) in the render window. In the video David showed that a low MRD didn't all enough rays to pass through the material, as did a higher setting.
@Tim Bateman: You're getting nice results.
I give up (for the moment).
@Roland4 - thanks for the screenshot. First, set preview at right in the IBL tab to Render in Scene (down arrow) because that helps you adjusting the values. You have Pitch low which means that the sun is near or below the horizon and you only get ambient light. The screen shots at left show a simple glass vase light by such a setting and at right when pitch is at 90 degrees to have the sky above the horizon. You'll notice that you get weaker light out of the HDRI but on the plus side more ambient light.
What you cannot see is that I've enabled Apply to light source at right of Intensity. This is to get enough specularity out of the HDRI. HDRI Effect has now too much light, so I used Linear Falloff at a Radius of 100 to compensate for that.
The vase I cobbled together with two spheres and a torus has the material shown below. Glass is transparent and specularity gives the gloss. Refraction makes it reflective without using reflection.
If you cannot watch videos because of Internet bandwidth, I have transcripts of some of them as PDF documents on my website (see sig). Go to Bryce Documents > Videos > Horo. There are links to the videos and also links Transcripts.
@Jamie - reminds me of games we played in the DOS times.
@Tim Bateman - looking really very nice.
More experimenting from me.
I tried using Horo's 'creating a terrain by using different resolutions' method. I had a great terrain and foam but Bryce crashed, not for the first time, and I lost it and all the settings. This is another try but the foam isn't as good as the last time but I am getting there. I remembered to save everything this time too :) I haven't bothered about lighting and the sky is the only thing I changed, and I don't like the horizon but as I am experimenting with other things I'm not really bothered at the moment.
Roland-very nice renders. Horo has helped with the tree in the bowl, give it another shot.
David- thanks for the new tutorials
Jay – cool job with the stacked terrains, not sure about the sky
Horo- thanks, you are correct Sean is my hero. Love the IsleX-beach render. Thanks also for all the detailed information you are posting for Roland, very helpful to me too :)
Tim Bateman – You are getting nice results with Wings 3D
Guss- Cool game, I agree with Jay some buttons are missing. I don’t think anyone plays video games with joysticks today. ;)
Fishtales- nice experiment. Saving all the time is the lesson I learnt from Bryce crashes.
@Horo
Thanks for your sreenshots and explanations. If i have make it, i will show the results here.
Why So Many Shadows.
Why is it that if I use a standard Bryce Sky I get 1 shadow from
an object when the sun shines on it, like in real life.
But when using an HDRI for IBL I get loads. The HDRI image is a sky with 1 sun and clouds.
Even with everything in the Sky lab switched off, apart from Sun/Moon Shadows in Sun & Moon section,
and the Cast Shadows in the IBL section. If they are switched off I get no shadows at all.
I thought IBL was supposed to give a more realistic lighting effect to a scene.
Sorry but HDRI / IBL is too heavy for me (in the moment). I have found a very good compromise between beautiful appearance and lower render time (40 minutes) without HDRI and i am more than satisfied with the result. I call this render ´My little tree`
IBL simulates real lighting, it doesn't reproduce it exactly. The HDR has several points of light... Or several really bright parts which act as lights and cast shadows. The easiest way to solve the problem is to set the soft shadows to full and they usually diffuse enough to not show.
@Sandy - the archipelago looks quite nice.
@StuartB4 - an HDRI is a sphere with point light sources. What you see is an image, Bryce sees the point light sources that are generated by the median-cut algorithm. Quality 16 means there are 16 lights. Actually, the HDRI is divided into 16 rectangles with a light in each of them. If quality is at 4096, the HDRI is divided into 4096 rectangles. Brighter parts have smaller rectangles and nearer together, less bright ones larger rectangles with a point light source in the centre. By the way, there are means to make those light sources visible using specularity, but it's tricky.
Now multiple shadows become clear. The sun is one point light source and therefore, there is only one shadow. If you use soft shadows, this point light source is slightly displaced several times depending on the quality setting.
Assuming a fully white HDRI and rendering a cube on an infinite ground plane with quality 16 there will be 8 light sources around the cube that cast shadows. The other 8 are below the ground plane and if Cast Shadows for it is not disabled, none of those lights can shine up.
Multiple shadows are a disadvantage of IBL and also of dome- and fill lights. Increase quality and you get more but fainter and less offending shadows but even more and eventually they blur into each other. That won't happen at 4096, it would need yet more light sources.
People using more expensive software than Bryce is use motion blur as post processing (done in the program) to blur the multiple shadows.
What we mostly do is disabling IBL shadows and keep the sun as key light with casting shadows. This gives you nice ambient light without shadow banding and renders very fast, besides. IBL shadows need time to render and the higher the quality setting (i.e. lights), the more shadows have to be calculated and that needs time.
@Roland4 - I like the left one more, but both are nice. Though I'm a great fan of IBL, it is not always the best lighting method.
another little experiment :) .... also, I am wondering if some one can help me out with something ? ....I have seen a lot of the "Golden Lighting" pack ....but can not find it any where, any help with this would be greatly appreciated :)
@Bateman
Is this real or a render ? I can see no difference. Very nice !
Well Horo, if you like the Left more, this is now for you. For your help and explanations. (Obviously I have today the intelligence of a potato.)
@Tim Bateman - outstanding render! Haven't you asked about Golden Lighting before? It was David Brinnen and my Xmas 2013 present to the Bryce community. DAZ 3D hosted it in our stores as a free product during the season. We asked to put it back into the store in the second half of January 2014 for free (like the Golden Rules). However, it never appeared. I'll ask whether they could put it back. I'll send you a PM once I have news.
@Roland4 - thank you very much. First time I've had dealings with an intelligent potato. ;-P
Thanks very much TheSavage64 and Horo.
Easier to understand now.
@Horo - yes your right i have asked before about that pack, but as you have said so far nothing has shown up :( ....but thank you for the help in trying to get it back up in the list's ...i really appreciate that a lot thank you :)
@Roland4- yes its just a render, good HDRI lighting with the right material can do amazing things in bryce :)
@Sandy: That's a nice looking experiment.
@Roland: Whichever one you go with, the tree in a vase is a real nice image.
@Tim Bateman: I'm with Roland, hard to tell that knight on horseback is a rendered image.
@Horo and GussNemo -- Thank you.
As I didn't like the horizon I lowered the camera angle and decided, as I had lots of sky to play with, to try out the Sky Lab.
This is probably the best of a lot of trial and error :)
It's all learning though :)
This started off or at least was going to be something else, but when I'd created the terrain, it looked like a good one to "stack".... so I did.
Now I'll get on with what I was going to do originally.
@Fishtales / TheSavage64
Very nice, i love these landscapes.
@Sandy: That's a really nice test image. Changing the sky and adding the sun really changed the atmosphere.
@Dave: Love that scene. The water really pulls it all together.
@Tim Bateman - Golden Lighting will re-appear, though it'll take a while because I'll have to re-submit it and it takes a while to go through the QA process and everything.
@Sandy - nice sunset (or sun rise).
@Dave - that terrain came out great. Mordor, isn't it?
