Hi,

 

i'm new to podium but familiar with rendering etc etc. i'm not sure on how to create omni lights / directional spotlights as other programs offer this to you as standard. i know podium is a smallish wonderful plugin that has very good rendering capabilities with lots of more experienced users / creator of such lights. Could these lights be made into components and made available for general use? therefore us not so experience light creators could benefit from them and they would everyone along with their lighting issues.

 

just a thought

 

i have looked around the forum for this topic but i couldn't find one so apologies if i missed it and double posted!!!

There was a few threads around discussing a possibility of a lighting forum where people could post and exchange pre made lighting components but it has yet to be created. It is a good idea though!

Nigel,

 

Some lighting manufactuirers already have downloadable lighting models. I looked up some manufacturers and posted a message about it elsewhere in another thread.

 

If you search the forum for 'IES' you should find it.

 

IES data for us is the 'holy grail'. It means we can just insert components and the light distribution and type are already predefined. Podium supports something a llittle like this actually with omni lights, so it might not be such a big task to implement.

 

Some time ago, I discussed with TBD the possibility of a part of the forum for sharing components and textures. Personally I think that this might work best if everyone sticks to a certain format to create these components, i.e layer names, grouping and texture names for LEMs and light spread.

 

I'll make some more enquiries.

IES implementation could be a BIG progress in Podium. But after the speed amelioration, TBD will probably have some other amelioration to work with (yes, I'm thinking about bump mapping , you know it's my favourite revendication...). But for sure IES and Skylight level total control could be... wawwww

Are you saying that we would be able to pull a light fixture out of a component catalog or D/L it from a  manufacturers website and drop it in my model and it will already be set up? That would be great..as would an open forum to exchange textures, components and pre defined lighting modules. (although being forced to do it yourself is a valuable learning experience!)

 

As someone with no previous render software experience, I have to say that getting the lighting set up so your model looks right is the toughest part of using Podium.

gotta say, that setting up the lights is the toughest part of any render

Fella,

 

This is exactly what IES data does - that's if I understand it correctly.

The IES data is the little graph type diagrams you seen in lighting catalogues which graphically depict the light spread. You just select the fitting you want, with the correct size bulb, and the work is done for you.

 

Viz has this facility, and God would I like it if SU and Podium came along and stole AutoDesk's lunch...

 

It is the best way to model lighting for realistic results, but there aren't that many manufacturers producing 3D models at the moment. Perhaps there is an opportunity there for someone enterprising who knows how to build 3d fittings with IES data attached. Even better, perhaps there is a Ruby script waiting to be written to automate creation of this sort of thing.

 

I guess it's a long term aspiration really, a bit like GDL support for SU...

Hi,

i have looked through various posts and tutorials regarding lights but i'm confused. Omni lights. i am i right in saying that you create these yourself by making an object, grouping and applying light to it? if not, how do you create an omni light? also, los of people mention LEM like its a selectable thing in podium of sketchup. what is it? am i overlooking something? please advise me as it looks easy for some people but its harder for others.

 

regs,

Nigel,

 

You are correct about omni lights. That is how you create those in Podium.

LEM = Light Emitting Material. It is a plane/surface/face that you apply 'light' to.

Other than the kind of lighting effect both create, the main difference between the two is that -

Omni Lights: In render, you see the light but not the group itself

LEM: you see both light and the face.

 

Hope this helps.

Er, at risk of repeating myself (again) there is an explanation and illustration in the FAQ that should be available any time now.

 

Come on TBD, it can't need that many changes

Er,

without repeating what some other users also point out, the tutorials are not that clear. not everyone has used this in beta stage so not privvy to long usage! maybe the tutorials should be more forgiving as they explain in a way that assumes you should already know. we don't all know therefore ask questions which is what a forum is all about otherwise, just post a heap of info and us read only. i'll try and be an expert for my next question but please, lose the sarcasm......

Sorry Nigel,

 

No sarcasm intended. That post was the latest in a series of about four which said the same thing, but about different topics.

 

I found a series of similar questions cropping up in the forum, which were being answered, but to varying degrees of clarity, and it seems that most people don't search the forum for answers first.

 

This isn't a criticism, because it is only natural, and I am as guilty of this as anyone else.

 

So I decided to try to make things easier for everyone and answer all the most common questions in an FAQ, but try to do it in an easily understood way which was quite comprehensive.

 

Anyway I completed this last Thursday (I think) and sent it to TBD. The reasons for this are that he may be contemplating producing some 'official' documentation or a helpfile (or perhaps posting a sticky 'FAQ - Please read this before posting' thread) , and that this information might be of some use in that regard.

 

So, I have been trying to help as many people out as possible so that we get a critical mass of expert users (not that I consider myself to be particularly 'expert') at least one of whom will be available to give help and advice at any particular time.

 

So, sorry if my frustration showed, it really wasn't intended! I'll try to be a bit more patient next time.
