So I've been back for two days and haven't commented. I actually lay in bed till 3 AM this morning, disturbed by what I'd read here. Yes, I've had a cow.

What really troubles me, more than the refusals to simply read what has been presented in the past to the tune of THOUSANDS of posts about GC, is the mis-representations of things I've said. I never said GC is some sort of cure all nor that you can only produce crap without it.

I have said there is a lot of art that shows the symptoms of not having GC or any other attempt to compensate for the sRGB color space we all see with, because we all deal with digital images and we all use digital devices that EXPECT sRGB images, regardless of whether they are photos or renders.

But more than all that, what really upsets me is the mischaractarization of postings in other threads, arguments about communication style, and the total bonehead arguments about t-poses and other dumb stuff. Seriously? You want me to spend 100 hours making "art" to demonstrate a simple skin lighting concept, comparing the difference between a couple settings? Pay me.

And that time I said "try VSS, then come back" was not the way it was represented here. It was not at all a case of me saying "use GC first or I won't talk to you". The poster needed help to make skin more realistic. I have written thousands of hours on that subject and posted over 1000 images about it and provided free software and shaders to make it a 5 second operation to fix skin. I asked the poster in that case to give VSS a try, and then if that didn't fix all his problems and completely blow him away, then he should come back and I'd give more specific help around the specific lighting and textures he was using. No way was that rude. And he was blown away and did not need more help, as far as I recall.

You who like to mispresent how I talk and then complain about it really irk me. The mods here have repeatedly stated that it is inappropriate to demand a specific communication style from others, particularly when you're complaining about how somebody is helping someone.

Bah.

People - do searches. Search for the word "crap", posts by me. Yes I use the word. No, I was not rude.

I also really am pissed about claims that I promote GC because I'm affiliated in some way with SM and this helps them.

That is the stupidest insulting part of this discussion.

Go back and read my posts for 5 years, trying to figure out why skin doesn't look right in Poser. Go read what I learned when GC came out. At that time, I was a user, nothing more. I did not work for SM.

Go read my astonishment at the difference it made when Poser Pro came out.

Then go read how I developed hundreds of ways to do it WITHOUT BUYING ANY NEW VERSIONS OF POSER.

Are you people so stupid? Did you think that SM was happy that I posted how to get GC done WITHOUT buying Poser Pro over and over? Do understand the ramifications of that? How could I be accused of some sort of nefarious "evangelism" when what I was teaching actually hurt SM's sales?!?

Perhaps it isn't clear, so I'll spell it out for you insulting bastards.

I published how to avoid giving SM more money for Pro features by using Poser 5, 6, and 7 materials to do the same thing.

I'm not asking you to buy anything or use anything. I'm simply sharing what I know. Yes there is always more than one way to get something done. And some of those ways are my favorites, and I understand them really well, and I talk about them, because they are the fastest easiest ways to get lights to behave as you'd expect, instead of getting stuff you don't want.

Double bah!

I'm going to a party now.

Go read this. I thought I already explained everything.

Note in the opening statement I said:

"You need to use gamma correction. I don't care if it's in your postwork, or you use Poser Pro, or you use gamma correcting shaders, or you use a GC lens. Take your pick."

Yes, it's my opinion you need to deal with it, but if Photoshop levels is your choice, that's fine. I never said you had to use Poser Pro or GC shaders. However, there are reasons to do it in-render, although such reasons do not apply to every situation. To use an analogy, if I suggest you should try limes in your cocktails, doesn't mean I reject lemons, nor does it mean I demand limes in everything you eat or drink. You guys need to stop putting words in my mouth.

Go look at the images in the linked thread. If you say you can't tell the difference, you're a liar.


Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
