Learning to Render (using Twilight)
-
Yeah the KT tutorial is great, really helped me out in the past.
Try these too:

Speaking of studio lighting, if you don't already know, also these are interesting (scroll down the page, it's called "lightsmith collection"). You have an OBJ model and an EXR file for each one. You can't use them properly in Twilight, but for example in Thea you can assign an emitter material to the emitting surface and then load the EXR in the emittance color slot.

I'm starting to get a bit of an understanding of this rendering business. Still not great, and only using the simple presets in Twilight but I sort of like the unfinished nature of this. It reminds me of many days in my work life. An empty, usually sterile room in the process of being set up for an exhibition. There should be packing material and crap everywhere but just imagine the blast of icy wind from the window has blown it all to the other corner. It's purely an experiment, how the light falls and transmits the glass colours etc. The figure on the table and the Cello on the box are two views of the same sculpture, and the leadlites in the windows are anatomically correct.
-
Those windows are great.
It does give one a chill from that background. (HDR ?)
Prefer less DOF for forground., (IMO) -
Cheers for the thumbs.
The windows were a bit of fun, a simple throwing together of shapes in my head used in decades of windows. I make them for a living. But it was the first time I've actually modelled one precisely in SU. The lead profiles are exact and cut as you would in a real one.The chilling background is the view from the window next to this computer taken a few weeks ago with my phone.
Off now to work out what DOF really means and how it's used. I assume it's depth of field, but I've done nothing to the camera view, pure vanilla SU and Twi settings
-
Just a close up showing that the windows are properly made. If you know your way around stained glass you will see that the lead work has correct profiles, only things missing are the solder joints, but that would be one more step into madness, and I think I've gone a bit too far along that road already. Next stage will be to make textures from my actual glass supplies so they are truly real windows.
-
Excellent work, Box. I like the glass composition in the frame on the floor. And of course the cello.
-
Thanks Tim, the one on the frame is an existing window. And it shows what I mean about making textures from my stock glass. I can then design and use "Real Sheets" of glass in the design, so the client gets what they see, not just an an ink or pencil representation of what the glass would look like.
-
Hell, they're all great. I am jealous.
-
Well while Rich is off there with his flights of fancy and the Borg Cylinder, I'm stuck here in reality. A broken bevelled leadlite stuck in the workshop corner awaiting repairs.
I really must sort out the colour balance, brightness etc of my monitors, I have three and these all look totally different on each. Who knows if even one of them is correct.
-
Regardless of monitors, can't you turn up the exposure or add a light? This whole thread if very interesting. Shows that rendering may come easier to someone who is already an artist. Good work! Is that some sort of beveled / quilted glass in the background. What is that piece?
-
That's sort of what I meant about getting my monitors balance properly. The one I mainly work on is much brighter than the others, so it sort of throws my lighting to crap.
The "Quilted" one in the background is what is know in the trade as a Convexlite. Very popular in the 60s in Australia. I made that as a tester to see how the distortion works, and how well the shaping shows up. The glass panes are heated so they soften and sag through an opening, this makes a sort of flat bubble with straight edges.
-
Yeah Box, they all look a bit dull or muddy. I think you need to calibrate your rendering monitor as you have said. Loving the work though, with some contrast adjustment and exposure tweaking they'll be gold. Get some more light coming in to see the caustics from the coloured glass, using interior+ preset works best for scenes with refraction and caustics
-
Oli, I've decided everyone else needs to change their settings as mine are obviously perfect.
-
Wow, bubble wrap doors. You should put those on Kickstarter
-
They'd certainly add a little something to your rubber room Rich.
-
Done a quick calibration of my Monitors.
Can anyone tell me if this looks clearer and brighter?

Excellent John, thanks for letting me know.
-
1000x better. Great image too.
Looks great on my mac. Not like anyone cares. I'm counting down the days til I get a real computer!! Sick to death of mac.
If you're looking for crit I suggest much more reflection to the wood textures. Gives a bit more oomph!
