Rendering Optimization in VRAY Sketchup

I have encountered these following questions "My client wanted me to print A0 size paper with nice quality, how can I do it?" Today I receive this from one of the follower with my Nomeradona Facebookpage "Nomeradona, I am working on a Google SketchUp 3D Floor Plan, and trying to Render it in Vray. I am able to Render it at (800x600), but I run out of ram, when I tried to output the (4000x3000 dpi) file size. Are there any tricks you can recommend to reduce the file size or increase rendering optimization?"

In this case, what shall we do? The good news is there is a very simple solution in Vray Sketchup 1.49.01 and here is this using the output vrimage.

This is an old Sketchup file which I did almost four years ago. Let me just use it to quickly show you the trick

Step 1: The output size

I have rendered before more than 8000px width x 4000px spherical panorama render which I used for this Virtual reality post. CLICK HERE to view this post. So far this was the maximum size I have tried. Anyhow in this particular render, I will make an output of perhaps half of this.

Step 2: IR passes
Since the image is huge, you don't need that high min/max rate. I lowered my min/max rate to -5,-3

Step 3: VRImage output. 

Locate the output roll-out window and under the setting output, tick the box "Render to VRImage". Once selected save it in exr root file to any folder that you want.

Step 4: Preview Image. 
Vray SketchUp will now begin to write the data in your hardrive. The Vray frame buffer will appear and you will see on the very top it reads "preview of the file output size that you have entered".

Once done, the image file will be written to the assigned folder that you have chosen.

Open Photoshop and load the exr file

Step 5: Converting the Gamma 2.2 to Gamma1.0
Vray SU by default uses gamma 2.2. When we open the file in Photoshop you should not be surprise why it's too bright. In order to convert the Gamma 2.2 to 1.0, select image/ adjustments/exposure.

Enter the value 0.45.45 ( 1.0 divided by 2.2)

Here it is..

I hope this is useful!

Abvent S.A has introduced Artlantis v7 for improved rendering

Abvent S.A. has recently introduced Artlantis 7, the most updated version of its robust 3D visualization software that is specifically designed for architects and designers.

Artlantis 7 comes up with various new features which can enhance the calculation speed and rendering precision. Besides, this newest version launches Twinlinker, an application that empowers the users to quickly generate and distribute virtual visits of their Artlantis and Twinmotion projects online.

Artlantis 7: New features

Superior artificial lights: With the accurate artificial light sampling method, it becomes possible to enhance the energy diffusion of the light sources in the 3D scene and reinforce the reflection of the satin materials by means of a brighter gloss.

Adaptative anti-aliasing: Powerful anti-aliasing facilitates the users to locate the areas to be rendered, optimizing calculation and curtailing rendering times, devoid of any modification in the image quality.

Twinlinker: The virtual visits app is created by Abvent R&D. It facilitates the users to generate and distribute virtual visits of their Artlantis and Twinmotion projects online quickly and easily.

Just export the images, panoramas and videos produced in Artlantis 7 to Twinlinker, then connect them to develop virtual visits. These can be distributed extensively by email (a simple link) or made available for screening on a website.

V-Ray 3 for SketchUp – Render with Accuracy

In the 3D modeling world, Rendering makes your design live and vibrant. It brings in the needed visual that you expected to have in your design. With the introduction of V-Ray 3, renders have found a way to easily convert their 3D model into the photo real images. The definition says that V-Ray 3 is a rendering extension in an advanced level that uses simulated photon wizardry to produce the photo-real 2D images.

SketchUp has popularly been known for offering the simplest solutions to the complex designing issues. Today, designers and artists use this software application widely because it offers really comprehensible functions that engaged solely for the designing purpose. V-Ray 3 is such an advanced extension that allows renders to make their design cutting-edge and stunning. The flawless depiction of your design is possible for the simplified user-interface offered by V-Ray 3 extension. There are more things to consider as it comes with a promise to give you a never-felt-before experience in the rendering process.

With an array of functions and features, it indeed gives you a new world of rendering. The content discusses further the benefits of using this application.

• Easy to use – this application, like other applications of SketchUp, is easy to learn.
• Quality – It offers you the highest quality renders.
• Power – as claimed by the application, it can render everything, even the most complex 3D models instantly.
• Speed – Speed is definitely faster than any previous extensions available. It allows you to spend quality time in designing.
• Creative Control – it concentrates on every detail of your design with different creative tools used for lighting and rendering.

It cuts down times that you suppose to give to other than your design. This makes your designing accurate and precision. Some factors need to be discussed without which the content remains incomplete.

Quick Start:

Clean and simple user interface comforts renders and designers so that they can use their creativity in the best way. The quick presets and streamlined controls enhance the workability and they are also helpful to bring out your creative skills. The features that may steal your attention away are described below:

• New UI – easiest user interface to boost the faster workflow.
• Material Library – it comes up with the 500 drag and drop materials to enhance your speed.
• V-Ray Swarm – scalable rendering system for a faster rendering.
• Denoiser – it eliminates the noise and makes the rendering time faster.
• VR – VR ready 3D model that allows users to witness the in-depth of your design.
• Aerial perspective – It understands the atmospheric detail of your design
• Grass – It gives your design a realistic perspective with real grass, fabrics and carpet.

The functions and features of V-Ray 3 are organized and simplistic. They look after every angle of your 3D model and come up with a proper way to solve the complex puzzle of your design. Whether it is adding physical materials or maintaining the accurate lighting, it offers the desired solutions. The realistic details are advanced to add a feel of a real world experience to your model. V-Ray 3 SketchUp changes the world of rendering completely.
