Ok in TS 7.5 WorkSpace with Bridge turned off, how do you change light intensity? If you drag in a spot or infinite light are there sliders?
Nothing in the Stack?
Why do I sense someone is going to mention the LE again.... |

probably you can't..
there is nothing in the LE that wouldn't showup in the stack for those lights..;) ..I noticed some don't even allow shadows :confused: how is this better? |

Yeah I too have to admit that working with the lights in the workspace is not at all intuitive. There really needs to be a more simple intuitive way to interact with them (like a simple intensity slider).
You can change things in the LE though. If it's a spotlight or omni, try changing the "AttConstant" and "AttLinear" settings. What do those mean? I have no idea. It's confusing but it seems that setting them higher makes it darker and setting them lower makes it brighter.
If it's an infinite or ambient light, you change the color to change the intensity. Unfortunately you are limited to how bright you can get them. Can't go brighter then white like you can on the model side.
Hopefully they will make the lights in the WS much more intuitive soon.
Edit: I guess Omni has a color setting too. |

Attconstant appears to be the intensity. Fractional values make it brighter. Whole numbers darker.

Thanks guys! Something as important as lighting certainly needs more attention. |

Really we should be able to select a light (in either LE or workspace view) and all relevant adjustable parameters should appear under the panels tab in the righthand stack. Burrowing into the LE for even the simplest tasks seems like an excessive number of mouseclicks - not to mention a pain in the butt. Perhaps its one of the things that will come with 7.51? |

Actually, when a light is selected it does show up in the panel section in the stack. It's the same panel as the node in the LE. I guess I just always have the LE open so I've gotten used to burrowing around in there more. |

Same here. I use the LE as a scene manager. It's a lot easier to select in the LE than in the 3D space if you use descriptive names.

Maybe I'm confused about available options for different lights but I had an occaision last night when I looked at a light in the panel view and all I had available to change was a colour box. I found everything such as AttConstant after a half dozen mouse clicks in the LE.
I too tend to have the LE open but shrunk - gets in the way otherwise - I still find it a pain and seemingly inconsistent at times but I'll save those observations for another thread. |

No Burnart your observation matches mine and welcomed here. Are there any controls other than color for an infinite light in the stack for example? |

i hope this is one of those things that'll get changed in the 7.51 patch. i don't mind the model/workspace thing that much but i hate having to flick back and forth for small things like this. |

Not to forget that switching forward and backward kills your shaders ... |

and no shadows on infinite lights ..guess the lights aren't really compatible with vray :( |

actually, if you flip over to Model side and select the light, you can add shadows, then go to workspace and render in V-ray, or render in V-ray on the Model side and the shadows do show up. While I was trying to learn V-ray, I ran across that "longcut" :D |

Actually I was not really referring to lights - mostly at this stage I'm confused by the way materials are presented in the LE - VRay vs LW compared to what is accessible in the Library and Panel views .... I only got hold of 7.5 a couple of days ago so I need to look at it a bit more and see if I can pinpoint the issues or resolve them via experience. So I won't comment more about that here I'll just keep tinkering and start a new thread if I feel its necessary.
Back to lights - I was going to ask about infinite lights but it seems that conversation has been had.:) |

I though the idea with lights was that the luminosity of it's color governed it's intensity. Adjusting the AttConstant value has the same effect for lights with this option, although it's more intuitive imo.
You can do both of these things in the stack. |

Having an intensity value separate from colour is important when you are trying to keep track of rgb colour change over time distinct from intensity change. Imagine the effect of a complex exploding overhead firework and you should start to see the idea. Intensity fluctuates - colour changes. You can do it with a single colour box changing over time but it would be easier if intensity and colour are separate. |

nice to know...but why not have it do shadows on workspace side then..:confused: thats not intuitive..it's a 'long cut' for sure :( |

OK, I'm back home now, and I decided to see if I can find it in the Link Editor - it's not intuitive, and I don't know how to bring it up one level, but I found it for the infinite lights.

that works..I exported it so it is now on a tab on the light in the stack or LE ;) |

Have you actually checked if Vray renders with shadows after checking "Cast shadows" in the Object Render Attributes?
Is not this the "light widget" object render attributes? There is also a "receive shadows" checkbox there (makes no sense for lights). |

The reason the shadow settings are buried like that has to do with the bridge. Checking the box will no longer allow it to sync with the bridge. So if you set shadows in WS side you'll need to manually change it in Model side.
Personally I'd rather have the check box on the top level and just know that I have to set them separately.

Nice pic Leif - when you re-read this thread from the beginning its easy to see why people are frustrated with this LE stuff for setting light parameters. Your picture makes it all look very complicated for those of us use to drop down menus and buttons - the LE is a deeply strange place. |

but by jove you are correct! and I did figure out how to export the parm. right-click and choose export. Then go up one level and export again to put it at the top level of the object. Naturally, for those things that are deeper in than two levels would have to be exported further. The first time I did this, I accidently exported the wrong thing. By right-clicking at each level and choosing delete, it removed it from that level only. Guess you would have to be careful not to delete it at the lowest level. ;) |

Just think of all the junk you have to dig through just to change shadows or light intensity. Is this better than the old way? Put the necessary controls in the stack like they should be. Was TS QA'd by LE freaks? |

LE may be where they are going. it is where you can change the gross dementions of object. also where you can add segments to the objects. I would at least like to have the shadow information right up there at the top. Including if they are mapped or rayed |

Thanks Leif, that is better..I didn't get a chance to try the other shadow checkbox before going to sleep last night but did think it seems like it was render options not light shadows..:rolleyes:
makes me think of an old joke..
how many experienced truespace users does it take to change a light setting in ts 7.5 workspace? :confused: |
