Very nice I would love to see an image rendered with these lights, to show its full effect.

I WANT! ^_^

Will it work with P5? I've noticed alot of P4 python scripts and other utils don't work in P5.

Very interesting postapulcino.
I presume you have seen shademaster's Poser 4 renderupgrade in freestuff which simulates HDRI using one supplied image.
Your app looks like it maps the light sphere to a rectangular map allowing colour gradiation on the map and corresponding lights.
Can you integrate the colour picker tool with this? Can the rectangular map take imported bitmaps/jpegs etc.?
If I can make one further comment, that is an awfull lot of lights in that array. Render time must be very high. Do you plan the app to use a standard array size e.g. 80 lights or will this be variable?
Otherwise this looks very good.

ooops you just answered the mapping question.

postapulcino you'll be my best friend forever if you make this available :)

great idea ;) when will be available ? P.S. but so you are a programmer ? best reagards Andygraph

VERY interested in this when it's available.

OK, I'm going to ask the foolish question. What are HDRI Lights?

My God, i've been waiting for such a software for so much time ! It looks excellent, so now, if it works as it should, you already got one sold :)

This looks like it could be very cool. Keep the information coming. I second STORM's question about render times. Do all lights cast shadows? Or will there be some way to disperse shadow rendering between the lights? Cool cool. Looking forward to this...

Brilliant! (In both senses of the word.) Looking forward to more info, and hopefully, a release...

That is awesome! I am interested, that's for sure!

Hi postalpucino !

it sounds interesting...but I don't understand why you call this application "HDRI light studio".

HDRI (High Dynamic Range Imaging) is an image format that encodes proportionaly the amount of light as floating point number instead of "colors". This is a more accurate physical model as you can have an "infinite" light intensity (from a very weak light source to a bright sunshine). With normal 8 bit low dynamic range image (jpg, bmp, etc...) you're limited to 255 shades for 3 channels (RGB).

Poser's illumination model use low-dynamic range (8 bit) value. Even if you use an HDRI light probe to set the intensity of lights, it will be limited by Poser's 8 bit format. Whatever you'll do, it's impossible to create or use HDR image in Poser.

What you are proposing here is "image based" lighting. This method - used mostly with radiosity rendering engine - has nothing to do HDRI. It's only a global illumination method...

But, hey, image based lighting in Poser is already great !

Looks like a winner, but I sure would like to see a demo before buying it - I've wasted too much money on lightsets that don't deliver already - not suggesting that yours wont - but I think you are on the right track here and it looks very promising.

Um... have you actually tried this? As a programmer I know that each poly will have to be lit by each light even in preview mode. My experience with poser is past like 4 lights or so your performance, even in preview mode goes down. That is a heck of a lot of light calculations and even more with shader nodes. What do you have like a 100 lights there? That's at least 100 dot products per vertex to calc lighting. Plus shader nodes that rely on light direction etc can even do dot products at pixel resolution per light. Well I hope it works but I don't think poser makes any distinction between static and dynamic lighting.

Mason, I regularly render with 20-35 lights in a scene for simulated GI. From what I see above, the system allows you to control the number of lights horizontally and vertically, thus enabling you to have,say, only 2x2 lights if you want a "quick render" GI, or, say, 7 x 6 lights, for a 42 light incredibly detailed GI setup.

Valandar I know the system allows it. I haven't tried it myself but my experience with programming graphics apps and using poser is the more lights, the slower the system. I'm just wondering if this has slowed down the system. I would imagine it does unless CL has some way to compute 100s of dot products as quick as 4 or 8.

This HDRI creator looks very cool indeed! I made the rendrupgrade by placing the lights by hand and tweaking them one by one. This would make it a lot quicker for sure. One question: When will it be released :) ?? Can't wait to try it out.

I think that if you have a system capable of running P5 you won't have a problem. I used GI all the time and it doesn't seem to affect P4 at all (I've got P5, jjst don't use it much) later jb
