Cool Video on the Merits of HDRI for 3D Rendering

The images you use as sources and output have a big impact on the realism of your renders. This video from dimensiont on YouTube looks at the value of using HDRI images when doing renderings. I think the video could use a different soundtrack, but the examples given are convincing.

Merits of HDRI in 3D Rendering

In the video, you’ll see the difference in colors, shadows, lighting and reflections between high dynamic range images and formats like jpeg and png. The video does a great job of making the difference in contrast and detail obvious. It also gives you some hints to the value for different lighting environments though I’d say the video could use more lighting examples.

Watch this video if you’re working on placing made objects and people into real-world environments or struggling to fine-tune a render.

Cool Video: See How Rendering Works in Games

Found this video on the HappieCat YouTube channel. This video is focused on rendering in games, but it does a great job of explaining the basics of 3D modeling including the different technologies and math behind it.

I work for a 3D rendering and visualization company, but my background is in marketing. While I’ve learned a lot working with FluidRay, this was actually a great video for me to learn a little more about the concepts behind modeling.

I definitely suggest this video to anyone looking for a very straightforward explanation of what goes into modeling, especially if you like video games.

Where to Find .3dm files

You can build your own .3dm files but it takes time and you may not get the best results. If you’re like us, then you’ve probably got a few spots you check for models, and you’ve also probably bought some sets over the years. But you always end up needing something you don’t have, and having to look around.

I did some snooping through my lists of sites to find ones that offered a good mix of .3dm models. Not all the sites are free or have large selections, but they are all dependable. Take the time to browse through a few of them when working on a project and you should be able to find what you need.

TF3DMhttp://tf3dm.com/3d-models/all/1/3dm
This site has a good selection of models, but they range in quality from high-end to beginner. You can find anything from full buildings to Black Hawk helicopters to a T-Rex. Prices vary a lot, and you need to be careful to check which license is available for each model.

CGTraderhttp://www.cgtrader.com/free-3d-models
A library of free 3dm models, heavy on automotive but you can find some animal, environment and product models if you look around for a bit.

GrabCadhttps://grabcad.com/library/software/rhino?per_page=20&query=3dm
Not a very large selection, but there are some nice ones here & the site has good search functionality.

AD-3D http://ad-3d.com/free-rhino-3d-nurbs-models/
This is a free collection — available for both personal and commercial use (but not reselling) — from Aleksandar Dimitrov. Mostly furniture models, but some exteriors like fields thrown in.

FlexiCadhttps://www.flexicad.com/download.php?lang=de&misc=1300
Honestly, it’s only 4 models here but its worth going to pick up the Audi TT model.

Aversishttp://www.aversis.be/3dmodels/
Not many here, but they are all decent quality. Click the links labeled “Rhino” to get the .3dm files.

Turbosquidhttp://www.turbosquid.com/
You’ve probably come across this site before. Big selection of models. You can search subject and then filter to get models compatible with Rhino. Pretty much everything here is high-quality, but you’re going to pay for it: prices range from US $5 – $500. Fortunately, you can filter by price. If you need a model for work, then this is a good place to look, but not sure its the right place for a student.

Craftsmansspacehttp://www.craftsmanspace.com/free-3d-models
If you’re looking for free geometries and pattern 3dm files, then I’d check here. Nothing to fancy is available, but you can use these models for things like fencing, icons, wall art without too many problems.

Yobi3D – https://www.yobi3d.com/
It finds 3D models on the Internet with simple keyword search. The models can be previewed in 3D right on your browser.

This list is a work in progress. If you’d like to have your model site, set or file added, then leave a comment.

MaxScript to prepare for exporting to FluidRay

This Maxscript for 3dSMax prepares the scene for better exporting to FluidRay RT. In particular, this script:

  • Converts proxies to full-res meshes
  • Converts VRayMaterial to Standard Material
  • Converts VRayCamera to Standard Camera
  • Converts VRayProxy to Regular Mesh
  • Adjusts textures to be more faithfully exported

Right before exporting, load the script in the Maxscript editor and press Ctrl+E to execute the script.

The export format that provides the best results is .fbx.

Get this script in the Addons Page.

How to Combine FluidRay RT Light Channels to Quickly Adjust Lights

How to combine and adjust different light channels separately without redoing the rendering. This tutorial builds on top of the Light Channels Tutorial.

The final rendered image is just the sum of the contributions of every single light in the scene. By rendering every light to a different image, it’s possible to adjust the contribution of every single light before summing them up to obtain the final image. This video will cover:

  • Extracting light channel outputs from the renderer
  • Visualizing the light channels in the Render View
  • Changing the light channels scale and intensity in real-time
  • Using the Image Sum node to add together the different light channel outputs

How to Use FluidRay RT Post Processing for Fast Render Tweaks

Introductory tutorial on how to setup a basic real-time image post-processing in FluidRay RT.

Rendering complex scenes can take some time. Post-processing in FluidRay RT lets you keep refining renders without starting over and see the changes in real-time. This video will cover:

  • Extracting the different output images from a rendering
  • Visualizing the output images in the Render View
  • Changing the color and intensity in real-time
  • Applying Reinhard Tone Mapping to adjust appearance
  • Automatically saving the output images at specific intervals

How to Use FluidRay RT Instancer Nodes to Render Highly Complex Scenes

FluidRay RT Tutorial on how to create scenes with thousands of objects without using much memory, such as a forest.

Complex models, such as trees and grass, can use huge amounts of memory. Instancer nodes allow to re-use the same models in different location of your scene, allowing you to create renderings with thousand of complex objects without much memory consumption. This video will cover:

  • Creating the Instancer node in the Graph Editor
  • Assigning trees to the Instancer node
  • Making the Instancer node duplicate the trees all over the scene
  • Making the duplicated trees stick on the terrain

How to Use FluidRay RT Volumetrics for Fast Fog Rendering

FluidRay RT tutorial on how to add real-time participating media to a scene, supporting multiple scatterings.

Volumetric effects, such as fog, god rays and clouds can add great realism to a scene.
FluidRay RT supports rendering homogeneous (i.e. the density is constant in the medium, such as fog) and heterogeneous media (i.e. the density varies in the medium, such as clouds). This video will cover:

  • Adding a homogeneous medium to the scene
  • Adding an object containing a homogeneous medium using drag & drop
  • Change medium parameters

How to Use FluidRay RT Ambient Occlusion for Fast Preview Rendering

FluidRay RT tutorial on how to render ambient occlusion in real-time.

Ambient occlusion is used to quickly generate a preview of scenes by approximating the light reaching each shaded point, based on how much the point is “occluded” by the surrounding geometry. This video will cover:

  • Using the Occlusion Integrator to render Ambient Occlusion
  • Tweak Ambient Occlusion Paramenters
