Twilight Render - Challenge
-
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?
-
Dave, I'll post the model next day or so. Haven't had the "faces" change when working in TW. I will say SU can get a little crazy with face orientation sometimes while I'm modeling. Never an issue when setting textures in TW ?

@Alvis - I really like this. My favorite is #4 (counting from the right). I downloaded your model and will try to understand it. I got an error because it is missing the background image. The background in your images does not match what I am seeing in SU but that is probably related to the error in not finding the background image.
Now I would like to understand the differences in the settings between the 4 images you posted. The only way I got the wine to show up with any red in the glass (in my image - not yours) was to go to an external render and then I lost the wine color in the shadow.
Just to let everyone know I have not completely given up, here is my latest attempt.
OK - One big thing I learned in this was that I was not paying attention to the shadow settings in SU because I never use them in the work I do. That helped a lot. Still a lot of experimenting to get this far. What bothers me most is not necessarily that the image is not the greatest in the world but rather that I do not seem to be picking up on some of the elementary things needed to do good rendering.
In another thread I did try some building renders with section cuts and hiding some walls but doing something like this wine glass is totally throwing me off. http://sketchucation.com/forums/viewtopic.php?f=15%26amp;t=64285

Dave , Posting the "rocks glass" model. You'll be able to check out materials and sun settings I used . It's a simple set up but gives a nice render on easy low through easy medium+ . Have one scene set up. Hope it's helpful.
