Do you like this image above? Do you like the realistic lighting?

I made this rendering using 3ds Max 9 and Vray render… and I want to give you that scene as a present for you readers!

3d model to add nice ditails in bathroom scenes type. Toothpaste, toothbrush, liquid soap, box and something else with V-ray 1.5 high photorealistic setted scene. Just Clic render button and get a photorealistic shot!

I hope you’ll like my 3d files! It’s a good opportunity to investigate my V-ray settings, to compare my setting with yours… to help each other about settings and lighting concept.

Tell in your 3d forum, tell your friends…. Download and enjoy it.

(The file is for 3ds max9 and V-ray 1.5 - Please don’t ask me about other format)

I feel sorry if someone of you got something strange from my blog.

I noticed unsubscribed users during these day and right now - Thanks to Peppons - I found my blog hacked.

I care my blog just because I’m 3d fanatic… I love sharing and to be a part of a community. I can’t understand why people are happy making this bad things.

So sad.

head 3d modeling

My first tutorial to start learning 3d modeling was Joan d’Arc!! almost 10 years ago!

Actually Joan d’Arc is the most famous tutorial for poligonal modeling in the world. But during these years many users added to the web their own contents about 3d modeling.

One of the last tutorials I liked is Head Modeling by Hatice Bayramoglu. Very detailed tutorial that start from a sketch and conclude with a finished 3d head model. Here the link:

Reading on the Hatice Bayramoglu site you can understand that this tutorial start with “head tutorial” but the idea is a complete tutorial about an human body!! Eye, hand, foot, lip and 3d nose.

Enjoy this fantastic tutorial and tell me… How many tutorials about human 3d modeling do you know?

training mental ray

Mental Ray training: A new videoguide to learn the excellent render engine that rendered the cult movie Matrix.

Even if there are many render engines on the market, Mental Ray is still used from many users. Mental Ray is very power to create special effects and it is excellent working with layered rendering!

As I wrote in my italian post Tutorial per Maya there are many resources about it especially for Maya users. A very interesting community is Mymentalray.com.

Recently I found this video guide that I think very interesting. Here a brief description of the author:

The only video course in english for mental ray. his video course is compound from 168 lessons for a duration of 22 hours. The treatment includes all the versions more important of this powerful motor of rendering. Examining the courses of the version 3.4 3.5 and 3.6 you will be able to manage all the versions
included in 3dsmax8.0 3dsmax 9.0 and 3dsmax 2008.

Besides the vision of the evolution of the sundry ones versions it will give you a mastery superior respect to a single video course or similar text in once of reduced learning thanks to the video.

Inside the course they are present the files 3dsmax for the tutorials.

The entire Metal Ray Training is based on 5 volumes but purchasing all together you will have a saving of 136 $ in comparison to the purchase of the single-hit 5 video course valued 295$

Have a good Lessons!

ivy-generator.jpg

Today is the first day of spring! So to celebrate it I want to purpose you same nice collection about 3d spring!

  • XfrogPlants Billboards: Fruit - This product features 60 billboard props of fruit trees and plants, coming from the much popular and praised XfrogPlants Fruit library.
  • big trees autumn - The plants show a surprising depth of detail. Single leaves and twigs are perfectly cut out.
  • tropical trees - Trees for exteriors - Texture Trees

But the first day of spring you cannot forget about the Ivy! I’m sure that a lof of you know Ivy Generator!! but If you never heared thi name I suggest you to follow this link!

Ivy Generator is a standalone program that will import .OBJ files and “grow” convincing ivy on the objects in the scene. Its actually quite nifty, once you get it to work. It took me the better part of a day to actually get it to work. That is, to import files exported by 3Ds Max.

Last but not least… Vray Sun! Tha first day, spring is coming and the sun shines in the sky. Here some tutorial to set vray sun and vray sky:

Have a nice first day of spring!!!

big render

Recently I rendered a lot of 6m x 3m Posters for Buildings under construction… and I want to share with you my idea to choose how many pixels I need setting my rendering panel.

Everyone knows that a book is printed in 300dpi: that’s the best standard resolution.

But if I see this book to 5 meters I don’t need to increse the resolution, I’m not Superman!!! I just need to increase the format. That means I’m reducing the resolution!

Ok.. look at this file: it will explain my idea in a look!

Considering the Visual Field: looking a book (21cm x 29,9cm) to 30 centimeters is the same thing than looking an imaginery Big Book (574cm x 395cm) to 5 meters!

So, this imaginery book is 19 times bigger than an ordinary book: that means I can print a big poster with a resolution 19 times smaller: 300 dpi / 19 = 16 dpi!!!It will be a good resolution.

a4-prova-rendering-thumb.jpg Checking resolution

If you want to check your rendering resolution, print a little part (20dpi!).

The quality image is not so good, but just see the printed paper to 2 meters: Perfect!

This is the method I use to verify the quality image.

Concluding

To print a 6m x 3m rendering:

  • Set rendering out to 4724 x 2362 pixel
  • Create a new document with Photoshop (6m x 3m / 16dpi)
  • Put your rendering into new photoshop document

Last suggestions

  • I prefer 20dpi that 16dpi… it’s my safety margin
  • You can render 80% and increase up to 100% with Photoshop: Render time will be cutted and nobody will notice that
  • If you have problem with memory errors, render your image in 2 parts

Et-voilà, Les jeux sont faits!

vray pinscreen

[ Vray Tutorial ] - In the 2005 the Nine Inch Nails made a new video: Only. It was a great success, especially among 3d lovers in the world!

Many people like its music, but the 3d lovers like the videoclip because it’s made totally with Vray! Vray Render is the really main actor in this 3d short movie!

The Photorealism is amazing, but the special effect who surprise everyone is that you can see at 1′30″: the singer appears in the Pinscreen singing!! That’s a gret effect… but not so complicated to realise.

Suppose to start from a 3d head model. This is the idea:

  • Render a sequence with Z-Depht (front view)
  • Use these images as Vray Displacement Map!
  • Final Render

Et-voilà, it’s done!

This is the summary of the Alzhem Tutorial. Here the link… enjoy it!

I would to see your results! Send the images at my email address! I’ll publish it with your name. Subscribe to the Newsletter!

color mapping

[ Vray Tutorial ] V-ray has various method to control the light in the scene. You can tune the lights and the environement but also you can play with Color Mapping settings.

Linear workflow: understand it!

Have you ever wondered why your GI renderings start out so dark? Well, in fact they are not so dark. The problem lies with the display device (the CRT or LCD) and that the software is not making adjustments for the gamma that the displays put on our images.

Look at this tutorial to solve definetly your darkness… ; )
