Well this is.. embarrassing. I managed to release the wrong version.
Everyone, please re-download the installer. The link in your email should still apply. Install right over the top, no need to uninstall.
Keeping the version number at 1.0 because this is the real 1.0
(I'll post this in the other thread just so everyone sees it) |

This would be great, but I'm tied up on Thursdays (not literally) as my wife has classes. Depending on what time she comes in I might be around, we'll see. |

okay i just downloaded dribble and it runs.
Is there a way to simulate a fresnel shader for dribble ? |

indeed, would be interesting to know what kind of shaders dribble support/can use. I got 3delight now running with silo and ambient occlusion like in the past, jippie. Is something like that also possible with dribble? AO? Whats with blurry reflections? |

Thanks Simon. Let us know when you've got a new version for x64 people to test out. ;) |

I am having fun again here. Dribble needed reinstalling. Emmanuel, care to share how you are getting fur?
here is a first attempt |

Ok I'll re-download when I get home (as usual I'm checking the forum over a coffe at work!). This will correct the problems allowing hdri, gi and crashing - yes?
Is it correct that I have to redo the 3Delight licserver startup everytime I want to use dribble the first time after a computer startup? That's been my experience so far. If so, is there some way I can create an automatic bat file/shortcut on my desktop to double click rather than messing about typing into a prompt window? |

SIW, how do you enable SSS effects if you do not have Vray installed? |

3delight installs a short cut that you can use to run the license. Drag and drop that to your startup folder if you want it to start when you computer loads. |

Using the translucent plastic shader triggers SSS.
I'll be beefing up support for the remaining reflectance shaders - Vizu, is there a Lightworks reflectance shader you use now? Or do you want it for transparency effects? |

Only shader I need is a mapped phong or blinn that lets me set a texture and/or multiplier for each channel. Fresnel and a setting for blurring reflections included of course.
Guess we could call it the (begin deep announcer voice)....OMEGA SHADER ;) |

SIW, can you post a sample scene with some "new" shaders and working GI. Honestly, I still (dribble is reloaded) can not get any difference between GI and non-GI renders. The only GI looks result is with HDRI, but again it does not matter if irradiance is on or off.
Thanks. |

SIW yes i work with the reflectance shader of Lightworks.
Yesterday i try to render few scenes (a sphere on a plane) and use different shaders for the objects.
I can´t get a good result :(
Can you share with us one of your scenes where the lights and materials in with the settings in dribble to play with it ?
This could be useful for all them they don´t know how dribble works (like me) |

Well like a good sheep (BAAA!) I to have purchased dribble and ran the gauntlet that is the 3delight registration process.
A couple of problems/questions:-
1) when using displacement why does the mesh 'blow apart'? is there anyway to stop/control this better.
2) I get no shadows at all when using mapped shadows, is this correct?
3) when using subdivision on an object the UV mapping gets badly messed up?
4) When using HDRI is there anyway to remove the color cast from the HDRI image (i.e saturation -1 in lightworks)?
5) When using HDRI is there anyway to prevent the graininess of the render other that increasing the samples which cut badly into render times?
6) And one I just thought as as I type... are dribble settings saved with the scene or do they need altering when reloading a scene?
So far I have had no results that even come close to the renders shown on the dribble web site. Would you be able to supply some of these scenes so we could try them for ourselves. (especially the displacement one)
Maybe a list of functions that are and are not supported in dribble would be a great help.
I don't want to sound too negative as I can see the potential of dribble and the work that has gone into it so far, but at the moment I cant see it being a lot of use as anything more than an amusing distraction. (sorry, sounds harsh but I'm a little disappointed right now:( )
Thanks in advance

Steve are you doing the SubD in workspace or model side? I suspect that we have to use model-side SubD for it to export to 3delight through dribble. |

Yeah, I wasn't bowled away per se but I am optimistic about it's future.
A few test scenes and tips might help...:) |

Here's a quicky shrine to the shiny ball....;)
8670
Looks like another steep learning curve in our futures. The above image is a simple blue HDRI and yellow infinite light.
Couple of quick notes:
GI seems to only equal color bleed with Dribble/3Delight.
Anti-aliasing setting doesn't have any effect.
-Jack. |

Why you don´t use Textures to give them more realism ?
but this pic shows that GI works okay so far. |

Jack can you post the same scene rendering with GI off to compare? |

I'm not seeing any difference, but it does take a lot longer to render with GI on.:confused:
I did notice that dribble didn't save my settings. So I can't exactly duplicate the previous render. :( |

I agree : this is the main issue with displacement. At the moment I can't create fur on characters.
I would advise Simon to work on this until his Windows64 arrives :)
GI still don't work for me, nor HDRI with my own maps ; you are not alone Changa ;) |

Remember that the only HDRi that works is a sphere probe. They work for me (see earlier image). |

For the curious, here is a scene rendered in LW and dribble.
Right image is dribble with same (LW) settings as the left image but with GI etc.
Notice heavy bump in left material to get displacement on the right. |

Oooh, lots of stuff to talk about, but I have to nip off for lunch. I was getting a 64-bit environment setup this morning, so I was away. Quickly:
- The issue with dribble not loading on 64-bit OSes appears to be solved. Basically, I should have specified that you must install the 32-bit version of 3Delight as dribble links directly to it. I also discovered that an error will occur if you don't have the latest C++ runtimes. I've updated the readme to give this information. If you're running 64-bit and have already installed the 64-bit version of 3Delight, it must be uninstalled first, then install the 32-bit version, then reinstall dribble. License should be the same, you can just copy it over.
- When you use higher order surfaces (subdivision, NURBS) the UV information is implied by the geometry itself. This doesn't affect Lightworks and V-Ray because they're rendering the polygonal representations, which tS applies its own UV mapping to. If you need specific UV info, you should "extract final surface" before rendering. If enough people want a toggle in the UI to automatically convert while rendering (keeping the original intact), I'll do that. If you don't mind getting your hands dirty editing text files, the option is already there in the default.drb settings file - look for <nurbstopolys> and change the 0 to 1.
- Displacement cracks. As I've mentioned, some are inevitable, but some are also avoidable with a change in the way I export geometry. I'll make that a priority then.
There are other settings in there that I don't expose in the UI - I don't really recommend messing with them, but if you absolutely have to, please make a backup :P
Alright, back in a bit. |

Got myself dribble. Here's a render i did with it. I like the light. I think it needs antialiasing though, how do i set that? |
