Twilight Render - Challenge
-
I took an existing model (not a good one) that I had had problems with before and tried some of the things Box had pointed out. Well, I got the glass showing up the way I wanted it but the background is a mess. Here is the render I created and a screen shot of all of the Twilight settings.
Notice how the background is a mess. I also tried a single background color and it did not come out correctly either. In particular, notice the grainy top portion of the background.
I have not even tried putting anything other that the silly objects inside the glass.Here are the Twilight settings (notice there are no lights in the model).
Welcome all suggestions on how to get the background to come out right/better. I am satisfied that I now understand how to control the glass itself. Thanks Box you gave me the tips..........
I have attached the skp file as well.........

a quick test with a different background

and the one on a wooden floor

I tried a of floor too but did not get it to work right either. Would you mind sharing you background info and the various settings?
-
Well - I finally made some progress.
Here is latest effort:
Now off to go back to the original challenge and draw the glass (and maybe a bottle) with liquid content.

at bigmanwashes they certainly have some big ass glasses!

Not big glasses, just small blowers

Is your background just an HDR image, rather than a physical plane?

In this particular case, yes.

My latest endeavor.......
Still not exactly what I want but getting closer. -
It's a funny result!

Dave C. , Stumbled across your post today. Twilight user also and you peaked my curiosity. Never have done the
glass of wine business so figured why not. Built and textured my glass like Massimo shows ( thanks
for posting that Pilou ! ) .Below I've listed how I set things up.Materials , Wine Glass - Snow , TW - glass / common
Top of wine - Indian Red 12% opacity , TW - glass / water
Side of wine - Fire Brick 12% opacity , TW - glass / water
Backdrop - Cool Grey #4 , TW - paint / eggshellTW render preset - 08 Exterior Daytime Progressive
TW Sun Settings - Physical Sky , Brightness - .800 , Haze - 20% , Sun Strength - 3.0
Gave the sun a very light yellow color. all other settings left at default levels.Let the render run for 100 passes. It took about 19 minutes. Probably as good as it will get with this setup. Need to
try some shots in an interior studio setup. Better chance of playing with lighting and use some other objects for
reflections and such. Good luck and just keep working with TW you'll get better with practice. Thanks for the kick to
do something a little different with SU & TW than I usually do. It was a nice change of pace.

Very good, andere cheers
-
Well, here is my latest try............
The wine does not really show up in the render but otherwise, it is acceptable.I have done a bunch of tries and just do not seem to get it right. I have also attached the SU file if anyone wants to take a look at tell me how to adjust it more properly.

Dave, scale is important when trying to get accurate materials, the above is way too big, try reducing it to accurate size before rendering.

I scaled the glass down to the correct size and rerendered using most of tuna1957's settings (not all).
Still does not match what it seems like everyone else is able to do. Either I am expecting too much or I just do not get it. I am failing miserable at this challenge.I am open to suggestions or if someone who has done this successfully would like to share your SU file (with Twilight settings) for me to study, I would really appreciate it.

Dave, Take a deep breath and step away from the keyboard
On a serious note try not to get to frustrated.
I'm no expert at this either. I remember having days I wanted to jab pencils in my head sitting at my keyboard trying
figure this stuff out. I've been messing about and tweaking settings and such. Posting another pic of a "rocks glass". Was going to tweak on your model but I'm still working in SU2015. If you'd like I'll post my rocks glass model so you can get in and check out how the materials and sun is set up.
-
is your index of refraction too high Dave? It looks like extremely thick glass (even though we know it is not)
keep going!! You'll nail it soon.

@tuna1957 - Thanks for your reply. Yes, I would like for you to share your model. I think I am missing something very basic but I do not know what it is.
@olishea - Yes, the IOR setting for the glass was too high. I set it lower but I am still doing something very basic wrong.
I have another question for anyone looking at this that uses Twilight. When I use the template to set the texture of the liquid in the glass, SketchUp reverses the faces of the liquid group. Is that supposed to happen?
