No, I dont think you read and took on board what I had to say.
I have incorporated emissive materials but I was asking for meshlights to remain (even if you do convert them yourself inside indigo)
Getting to lights from inside the phong menu for instance doesnt make for a logical UI/workflow
Look at this statement:
Sure, just integrate the emitted spectral radiance (as determined by Planck's law) over the hemisphere, over all wavelengths, and over the surface of the emitter, which will give you the total emitted power (100W). Then, assuming your undetermined variable is either the surface area of the light source, or the temperature of the light source, solve for that variable.
This is techno gobbledegook to most people.
It may be quite true but its far more than people need, or want to know or grapple with.
No matter how accurate this code is it has to be readily useable by the 'public'.
If I make a script available to Blenderheads I want them to be able to use it pretty well straight off cos it makes sense.
Blenderheads are all nationalities and ages.
I dont want to have to spend hours interpreting and translating stuff and answering forum questions for people just to get a simple render out.
Why shouldnt a 14 year old from Chile be able to use this renderer?
Furthermore time is money in the commercial world. People want to load something up and use it directly. People love great render results but they love simplicity as well. KISS wins.
Quite obviously you have a particular interest in the scientific aspect of rendering (which is good cos it makes for high quality results) but you have to think of what the end users need...and I dont want to hear a fob about it being the exporters responsibility to patch together a lot of obscure variables...
You want to sell this renderer..- it has to have a market
Like any successful product you need to tailor it for your customers needs.
This is a fact.
Producing a blue and yellow striped Rolls Royce with a 660cc engine may be personally interesting and satisfying to some manufacturer but its not savvy and wont keep him in work or help people with transport who cant use his produce.
sorry to get on your back but it seems necessary
