To Render or NOT to Render

Hi,

Difficulties in creating a realistic rendering lay in details. You have to think that the real jewel doesn't have any sharp angle because of the polish work for example. You have to use metal not 0% rough because it is something we never have in reality.

The lightning is not really important for reality, because a bad photographer - as I am :'( - will have bad ligthning results when rendering or when shooting.

As a photographer you will alsways be able to tell such things. It's not about how you see the rendered image, but what the mayority of the people/customers thinks about it. And as Sebastien says, the finished product will always have less sharper edges as drawing, but when you use variable fillet under the modelling tab, you can get your drawings to look more realistic.

I have used some rendered images for advertisments and always got someone in the store with the ad asking if i still had the jewelry in stock. So for me it works and it saves both costs as time.

here's an example:

Hi Bokeh, 

No, it wont. You just need to know a few tricks. Whith Render Studio, you don´t have to worry about lights, or material, it´s all predifined.

The worst part comes when we extrude. If you don´t use variable fillet,  your renders will look cartooned. As Sebastien and Jochen said.

 If you have shapes, they will look great.

I'm still very new to R/G so please excuse me..

You use variable fillet and the rendering stage? Is that right?

So, the benefits of rendering are you can show clients, and would you say it is a cost effective way of working, not having to carry stock? not having to produce items that sadly might not sale

Hi Bokeh, 

that´s right, the benefits are that you don´t have to carry stock.

Again:

• When you extrude your curves, you will need to make a variable fillet on borders. ( be carefull with the radius you fillet, if it´s too big, it will break your solid) Then you go to render studio, and you apply materials there. Be sure that you have installed Rhinogold render studio. Otherwise, if you render with native Rhino rendering, that will be very poor, you won´t get real metal effects , and it will take you ages to get a decent rendering. Also with RG Render studio, you can make easily animations. Check on the video section some of my videos, and you will see what you can get.

Regards

The render can give you the aproach of the finished piece, in my case the jewelry I design is meant for mass production so I need to make my idea the more real as possible in order to get myself clear to handcrafters. And for adrvertising or freelance work, remember that the love from first sight is possible so the better you show your idea to the client, you'll have much more possibilities to success. And I think that the lighting its the most important thing for a render, such as fillet edges antialiasing efects and photoshop postproduction.

 

Sorry if I made mistakes, I'm improving my english... :)

Here are a couple of images rendered on V-ray.

 

Have a nice day!!!!
