Lighting Plugin for Sketchup

REGIS

Hi AdamB

I have this problem with LU when I apply a texture in my model.

An idea ?

Its a bug in the demo. (TBD came across it earlier too). Easiest solution is to regenerate the lighting by making a small change to the model (eg add a single line) that will cause LightUp to regenerate everything.

Thanks Adam

I'm really appreciating the feedback on LightUp (good and bad). Models that show up problems are especially welcome..

BTW I worked on a model this morning that was causing a user some problems. So I've identified some code I can really speed up which was the bottleneck. However, it showed up because a model of a small room with 500-700 faces had a plain dish/plate on a table - it had 21,000 faces in it! Yikes! Made me smile anyway.

Adam, good to see the info is of some use. I would imagine that the plugin would have to be fairly robust as there is bound to be a high number of polygons in some scenes it will be used on eventually. Most people using this plugin will be professionals, which leads me to conclude that the models won't be that simple or necessarily low poly.

I've had some SU instability issues with the demo of the plugin loaded, but it is understandable seeing that it is still in development stages.

Speaking of which, you know what you've done by releasing the demo? Created a HUGE anticipation. Now I can't wait for it to feature. I've also left a comment or two on the LightUp forum you've set up.

Fantastic....this will be an excellant plugin when ready.

No, I wasn't suggesting that. I was observing that when LightUp is tried on a "simple" model and takes 10 minutes then perhaps the model isn't as simple as you think! Or its a bug.

Can you PM me with some more info please. Platform, crashlogs would be great etc.

Well I'd be a liar if I said I'm not a bit apprehensive but I wouldn't have started this if I didn't believe its 1. its useful to people and 2. its do-able.

Adam, some people don't understand where it to apply, maybe they test and don't want to involve it into main workflow('coz it is simple enigma for someb...)

For me, 1. lighting analysis(most of my work is engineering)...in mobile process with client...without connecting with any standalone application or web service.
2. shadow helper(maybe with skp-styles) for fine pre-viz picture in sketchup enviro. 3. again shadow helper with uv-wrapping(mapping...) for external app..

Anyway thanks for your hard work!

Thanks Adam for what looks like the future of Sketchup!

However, I'm can't get past this step... my setup, old iBook G4, OSX 10.3.9, sketchup ver5.

You'll think it'll run?

Thanks a million!

Well LightUp is for SketchUp 6 so its looking for a path on your Mac:

/Library/Application Support/Google SketchUp 6/SketchUp/tools

Its not finding it so indicates it cannot install.

What you could do is create that folder, let it rip and move the files manually. No idea whether it will work. It may be wholly incompatible with SU5. I have never tried this.

You would need to copy over from the "tools" folder, lightuptools.rb to your SU5 installation/tools and the entire folder called "lightup".

As I say, I've never tried this, I can think of many reason why it won't work. But let me/us know!

Ah, ok sounds like you're out of luck, spadestick. I'll be watching closely to see if there is any demand for this though.

thanks guys!

This looks very promising Adam !!
What is the maximum face number in the present demo?

Hey thanks!

There isn't a hard limit in the demo. However, the demo has some crash bugs in it (now fixed internally), some incomplete features (eg support for Groups and Components which is now fixed internally) and more importantly used some Ruby methods to extract geometry information which is very slow.

It is this latter issue which means for larger models you have to wait an inordinate amount of time. We know how to fix this and it will be for the next released version.

Short answer is LightUp is aimed at large models.

Great!
Thanks
will be resolve feature for user with limited rights(non-admins...for windows)?

^^ Brings tears to my eyes...

If only SU would handle large models better... (nudge-nudge, wink-wink GSU developers)

Yes saw your post. I'm a bit unclear what the problem is here because LightUp isn't doing anything that requires special permissions. Its just some Ruby and some C++ running as a plug-in to Sketchup.

Any more info you can provide would be really appreciated. And I'll try and get a repro here.

Thanks.

what happened to the lightup forum? even logged in i cannot seem to find it?

I did some tests.
To get rid of the psychedelic effect, I had to either explode groups, or make sure there are no groups in groups or modify the group, like add a line in the group.
Adding a line at universal level did not correct the problem with the group.
Also, (to contribute);
There is light behind the feet where there shoud not. The dog looks above the platform.
Some faces of the "dog" are somewhat transparent; see the corner of the platform that should be hidden, for instance.
And edges appear somewhat chunkier then model really is. (maybe because of the unwanted transparancy)

The test model has 2 groups, the dog and the platform
The transparent effect is gone if I explode the group.
