Lighting Plugin for Sketchup

AdamB

adam,

two questions:

@unknownuser said:

Also by default any material whose name begins with “$” will be skipped
when calculating lighting so they will be displayed at full brightness all the
time. This is useful to create fake emitters.
(from getting started with lightup)

this must sound like a dumb request, but would you care to elaborate on the above? i do not understand what you mean by it. and what would be a fake emitter in LUp's sense?

and secondly, what is this component for?

Fair point, "fake emitter" is a bit confusing. What I mean is that a face with a material beginning with '$' will be always full brightness as if it is self illuminating like a real area emitter. This is useful sometimes when you want something to look like a bright light but not actually emit light. I posted studio2.skp a day or so ago; the windows at the back of the room are bright white "fake emitters"; they come out bright white but add no lighting to the room.

Secondly, that is a LightUp component called an Irradiance Cache. It is discussed in the getting started document. Basically, you place these in your model to hint to LightUp where reflective surfaces can get there reflection information. It is a method getting fast reflections during the Tour tool mode.

PLEASE HELP!
I just registered trying to downloud this MARVELOUS plugin from AdamB,but unfortunately the compressed file does not appear.what do I must do?

Edson

adam,

thank you for your patience. fake emitters understood. i went back to the skippy and played some with it.

as for the Irradiance Cache, understood in theory . i have yet to see it in action to fully grasp the idea.

regards.

After you've registered an email is sent to you.
You need to click on the link in the email LightUp sent to activate your registration.
You then login and go to the download page to download the demo.

I'm planning a video tutorial very soon.

Is it possible (or can you make it) so that we could export the model with baked lighting?

Efrado

Thanks ADAM for this your astounding work
which promises to be an incomparable and fast tool for rendering the SU projects.

I am going to start studing the documentation.

By the way did you find the corkscrew? Ihope so. Drink a big sip for me

Thanks Adam. I just got my DEMO and docs. Anxious to play with it. Congrats!

Hi Adam and thanks for your plugin.

I'm playing with light up now but I don't find the point light component in the component's window.
Where is it gone

Thanks.

I reproduced the steps shown in the video tutorial but what I get is a white screen.
what I am doing Wrong?

For all those who are unable to unzip* the file (blocked), is there any chance of a new zip file?

*despite using properties to unblock. BTY this zip file is the first I have ever encountered that will not unzip.

have you tried reversing faces?

Efrado

Hi Edson,Yes I always check that,

I wonder if it could be a graphic processor problem?

I use a tablet PC with GP Intel(R)

thanks

i want too to ask...i remember some technics from skindigo by Dale Martens (aka Whaat and thanks a'lot for it): exporting of photo matched picture...Can we use sample preset to do it?

Might be. You could try Tools->LightUp->Force Simple Rendering, then restart to pick up the change.

LightUp only draws front faces so Edson is right, checking your faces are the correct way and/or fly around the model to check they're not facing the opposite way you expected!

You might also set a non-white background to be sure its not white materials on a white background rather than not drawing anything.

Although they will be fixed, right now LightUp has problems with:

groups of groups
components inside components
Instance/Group materials
Highly tessellated geometry.

Yes, mail "help at light-up.co.uk" with your reg details and I'll flip some bits.

[FWIW Its just a regular zipfile. No, really it is!]
