today I learnt…

…that HDR maps exported directly out of the Sky Lab in Bryce 7 as EXR are kinda different.

The torus on the left uses the Cook-Torrance model built into 3Delight’s trace() shadeop. The torus on the right uses the Ashikhmin-Shirley one. Look closer, and you’ll see that the A-S model somehow thinks the skymap is grayscale, while C-T does not.

It’s not the best example, really, but it’s a fact. I’ll post a more noticeable one later.


My old skymaps I rendered to HDR “normally” are seen by both models as coloured.

I need to see if saving to actual Radiance HDR will change anything about the way Sky Lab exports maps (it’s significantly faster than having the whole scene render!!). Failing that – I’ll have to figure out what all those parameters mean and if they affect the export somehow.

I don’t even know the mechanism that may cause this to happen. Damn, I honestly don’t feel like reading through the whole OpenEXR specification.


just in time

DAZ3D just unrolled a Victoria 8. And a new free female Genesis model – which isn’t called Genesis 4 but Genesis 8.

I don’t have the time to look at the free one right now – but the marketing talk includes “a new expression engine” and “automatically flexing muscles”.

For the latter to be included in a base figure – or at least a major character like V8; no idea yet if the free one features it or not – I honestly applaud. One of the reasons the original Genesis is my preferred figure is because it has a system like that available in one of the add-ons (Muscularity, I think). G2F had a similar add-on (which I also have cuz it was in a nice sale), but nothing of the sort is out there for G2M (and I can’t be bothered to convert all those JCMs and MCMs, y’know).

Now, expressions, I wonder if they did hire someone with a basic understanding of anatomy.

No idea when I’m going to look into that, but hey, as soon as I do, I’ll drip some acid right here.

Meanwhile fire up your DIMs and go download the new G8F starter essentials. They say there is some clothing there. It’s reasonable to assume it’s backwards compatible ;D

these are in FastGrab today…

…and I confess I do not see the point.

The alterations these – or any other “bend fixers” for Genesis 2 and beyond – bring are minuscule. I need to really scrutinise the renders to see the difference. It’s not Gen4 or earlier Poser stuff, where the improvements introduced by similar products jump out of the screen.

And none of those ever made raised-arm poses look believable.

Is it just me?

PS I think I’ve only seen two “hand fixers” in my life: one for Genesis, which makes the results even less realistic IMO (at least when I compare the promo renders to my own hands); the other for G3F, which I have obviously not even looked at because I use G3 in a very limited capacity (and actually I’m thinking about transferring those morphs back onto a more manageable figure like the original Genesis…). Which is weird because hands are the second most important thing in portraiture after the face.
