Add reflection to wrapped image

Hi Carrara Group,
I’m trying to add a reflective layer over a UV wrapped image on a cup and I’m not sure how to do this in the Layers Tree.
The reflection will be meant to represent shiny clear plastic with the label being behind it or under it.

Sorry I can’t post an image, it’s for a job.

Any advice will definitely help. Thanks.

If you want that deep, image under glass or plastic look, I might try duplicating the model, scaling up the second and giving it a glass shader - straight from the exAample shaders that come with Carrara - so that the second (outer layer) model is nothing more than a transparent, reflective surface… much like how DAZ figures have a clear coating over the eyes for such reasons.

So you want just the UV mapped image to be reflective?

You may not be able to share the actual image due to contractual obligations, but can you post a reference image from the web somewhere that shows more specifically what you want? Maybe a simple mock-up?

My first thought is that you could put an image map in the reflection channel to define what reflects and what doesn’t. If the whole label is supposed to be equally reflective, trace the shape of the label that you’re using in your image editor and make it white with the non-reflective area black. I could be have it backwards, so if I do, there’s an Invert Color checkbox that you can enable near the image map thumbnail.

I find it somewhat liberating not to be encumbered by accuracy.

Dartanbeck,
Works beautifully, Exactly what I was looking for. Thanks for pointing me in the right direction.
I was stuck in Shader mode.

Thank you, I’ll remember this tip.

I’m in the middle of rendering right now, so I’ll have to get back to this when I have some time.

So here’s a simple UV mapped vertex sphere. I saved out the template so I could do a basic paint job in PS, although you could use the 3D paint tool in Carrara for this as well.

I created a color map and loaded it into the color channel. I also created a black and white map and loaded it into the reflection channel. The shape is white and reflects. I inverted in one of my examples to show how it looked.

Thanks Evil Producer,
I will try that technique out also. Very Cool. It’s always great to learn something new.

Here’s a unbranded example of the Plastic Cold Cup. This is using the an additional cup wall with the plastic applied.
The actual render that we’re using came out much better than this example. Tweaked the lighting a lot, but this should get the idea across.
The environment map and the counter top are showing up in the reflections on the cup.

That looks great. Can’t wait to see the advertisements! As usual, Dart’s advice is spot on!

When the ad does come out, it would be cool if you could let us know where to look for it if it doesn’t violate any NDAs. People here are always eager to see Carrara used in a professional context, Wouldn’t hurt DAZ 3D to know that people actually use Carrara to make money as well. wink

Will Do,
It may take a couple weeks for everything to go through. I’ll make sure I get a copy and post it back here.

I’ve tried many 3D programs, Carrara made the most sense (to Me) from the first day I tried it, it just clicked with my brain.
It allows me to visualize concepts for the non visualizers and I can do a lot of things the guys with the $3600 programs do.

Every now and then I get hung up on something, but there’s always help here on the forum.

Thank you Evil and Dartan, you really helped me out.

Awesome! (Just got home)

When I was first trying to wrap my head around what the various shader functions are capable of… or more… just trying to create various looks via shaders, I found that the immense catalog of examples that come with Carrara are a great place to learn from. So I made some sky domes (this was before I discovered how easily Carrara can make and use spherical background images) so that I could really see the effects of highlight, reflection, refraction, etc., and would load in example shaders onto an object and set up some lights to experiment with how the shader looked. ThenI’d head on into the texture room and take a close look at each shader channel that was not set to “none”, and learn ways to use various procedural channel configurations.

Generation 4 figures, namely Victoria 4, really blew my mind as far as how nicely a 3d figure can be set up for great texturing. Having a separate mesh on the outer circumference of the eye is SO exceptional in a fast ray-tracer like Carrara! If youever use figures like V4 that have an outer eye layer, try the fun experiment of dragging the example “Glass” shaders onto that layer. Then you can go in and tweak the shader to be more or less reflective, change the highlighting, etc., just play around and render the results.

Speaking of learning from Carrara “Example” files from the browser, the “Scenes” tab has a plethora of excellent lighting setup examples to glean ideas from! There’s the “Lighting” category, but also “Interiors”, Logos, Effects, and more. Most of the scenes that come in the browser have some sort of great lighting technique to examine - much more so than any other 3d program I’ve ever seen.

It’s like having tutorials built right into the application!

Check out the Misc tab in the browser. There’s presets for modifiers, skies, volumetric lighting… all manner of fun experiments to delve into!

Carrara - the Home Movie Maker’s Dream Software!

There was a buzz regarding a great effects software on the market called “Hit Film 2” recently. I checked it out and… yeah… most impressive it is! Then as I was checking out a bunch of the highlight videos, I was seeing effects that I can already make using good ol’ Carrara - a wonderful app that I already own, and love to use!
True, much of this stuff can be a real benefit to be able to add quickly in post. I bought Dogwaffle Pro: Howler for just such things. I’m not sure about Hit Film 2, After Effects and others, but in Howler, I can use Carrara to actually create animated effects brushes with an alpha channel rendered into it! What a blast! What a Pile of Power!

Okay… perhaps a but over-enthusiastic. But it’s coming from a guy whom never really has a pile of cash to toss around. So I have to invent ways to fix things using parts from my local hardware store… ways to create my animated visions using not much more than my favorite reason to head to my computer… the amazingly inexpensive Carrara Pro, with the amazingly inexpensive Carrara Partner Post Softy: Project Dogwaffle Pro: Howler!!!

Oh… am I babbling again? Ummmm…. Yup! Sorry!

I did not forget about Posting the Flyer. just checked today and it’s still in review.
UPDATE:
I have attached a finished, clipped, render of the Aroma Joe’s Cold cups. All modeled and rendered in Carrara 8.5 Pro.
These were used for conceptual design to show the client and were going to be used on a counter card but they ended up changing the size of the cup midstream, so Photographs were used instead. The current taller cup is available through their Stores and website.

I was very happy with these renders. I know there’s a little bit of cut off of the pattern at the top and bottom edges but I’ve since learned how to fix that. 3D is a long road.
My Design is on the left and my co worker’s is on the right. He’s a very talented artist. He sketches everything out. inks it, scans it and creates the final art in Illustrator. Both cups have artwork all the way around.

Very cool! It’s nice to see the final product. It’s also great to see Carrara used professionally.
