setting global ambience value based on active pass

[Tim Leydecker]

Hi guys,

is there a way to set the Ambience value depending on the
current pass, e.g. have one pass with zero ambience and
one pass with something like ambience = 1.

I use the architectural material as well as the strauss material,
these don´t have ambient values I could mess with, wait,
I really wouldn´t want to do that anyway on a per/material
basis...

You can make an override on the individual RGB values of the ambience, I believe.

Maybe

Hey Dawa,

thanks for the suggestion but that´s exactly what I´d like to avoid,
simply because I allready have loads of materials scattered all over
various passes I can hardly keep track of and there´d also thats some
of these don´t have an ambient slot (althought they react to ambience...)

I could allways create an extra scene or manually set ambience
depending on the actively selected pass but I had hoped there´s
a script (e.g. pseudocode "on pass active/rendering set ambience=[value])

flash, about the only scriptlanguage I can grasp, barely.

Whatever, "I´ll goto and stop"...but Thanks!

Cheers

Actually I mean that you can override the scene ambience setting not the local material setting. If thats what you want. I'm not exactly sure.

i seem to remember that you can't get to the global ambience at a pass level.
I usually have a hidden basic object with a material named sceneAmbience with a lambert connected. The ambience values for this can be linked via an expression to the scene ambience.

The 'sceneAmbience' material's ambience values can then be overridden as you wish.

Yah that should work, but you don't need to.
When making your override just go into any object in your partition and select the Ambent Lighting->Ambience->then set an override for each of the RGBA nodes.
Then you can set the colours levels for each in the overide, it should affect the entire pass not just the partition or local objects in it.

Greetings all,

By chance has anyone had any fortune getting the Realflow import/export
plugin installed and running for 64-bit XSI? Next limit's XSI plugins
only seem to support 32-bit. But before I fly to Spain and raise hell,
I thought I'd ask the community. Any feedback would be appreciated.

Thanks for anyone's time.

Best,

Chadwick

When I enquired few months ago they said no, things *may* have changed since then....
Please do let us know if it has
Cheers

Getting stuff like this out of them is like getting blood out of a stone. Their problem would appear to be the time it’s taking them to build and maintain a number of plugins for their product. My argument would be that it’s as much a part of the product as is Realflow itself - after all, what good is wireframe and hardware shaded - but it doesn’t seem to be sinking home that they need to spend time there, for the sake of their users as well as their own reputation. In the past they’ve been able to play the XSI user base card but that’s changing fast and if they’re careful it’s going to bite them.

 

They do seem to be aware there’s a problem, even if they’re reluctant to address it. Several months ago they raised the question of open sourcing their plugin code and asked if I’d be prepared to take handle that process. I did say I would but that’s pretty much the last I’ve heard from them. It seems to me that in this case, open source would be a pretty satisfactory solution for all concerned but it seems they no longer agree. Shame.

 

There’s also a lot of useful information you can export from Realflow, velocity, temperature, etc, that won’t have made it to the standard importers. Once again, shame.

So it sounds like they need a good, swift kick in the rear!  Lets give them hell!  Seriously....we should all bombard them with phone calls, email and forum noise until the give in.

Hi guys,

I´m sorry for the delayed response, am stuck
head over heels in renderbin.

I resorted to setting ambience by hand, since
I had to again go through all passes anyway.
Umhhh, the joys of last-minute, nested changes...

I´ll look into what you´ve suggested, setting
global ambience per override seems plausible.
(I must admit I avoid overrides usually).

Thanks again,

[kim aldis]

Been done. Honestly, it’s a black hole

Then we need a doomsday machine. Professor Farnsworth should have one
close at hand.

FYI -I gave the RealFlow sales manager a bit of a nudge and shared some of your comments.

Hope you didn't send them by email.

Maybe their email servers don't work. It would explain the
longstanding issues the XSI community has had getting responses from
them.

Send your chair or dead fish.

To add some more, I've had couple of opportunities regarding fluid sim,
but what I've read about realflow scares the crap out of me. That is the
reputation I'd not take such burden to cope with. It is engineer stuff
anyway, seems industry is having interest on it and money to be taken.
Others might tear their hair off, I'd die. So you people keep tearing your
hair. Sorry can't help with more noise, ran temporarily out of it.
