3DS Max And Vray Tutorials for The Masses and A Whole Lot More. CG Education. Switchers For Randomizing PatternsBy Neil BlevinsCreated On: Dec 10th 2013Updated On: Feb 17th 2014Lets say you have a bunch of rocks in a scene, and you want to give each rock a slightly different color to add variety.

What you need is a switcher. What is a switcher? Basically, you define a set of patterns, and they get assigned to specific groups of objects, faces, etc, usually using some sort of ID value that connects the pattern to the thing its being applied to. So for example, you create a rock material that has 5 different rock colors, and then spread randomly the ID 1 to 5 on a bunch of rocks, and each rock receives one of the 5 rock colors. Lets use 3dsmax as an example. Using Multi-Map / MultiIDMap / VrayMultiSubTex If you want to apply completely different materials to these objects, you'd use a material switcher like the sub-object Material. So here's the basic process... Lets say you have a bunch of seperate rock objects. Run my iDSetter Script.

Set Low to 1 and High to 5. HDR Sky Lighting for Interiors. Notes on noise..

HDR Sky Lighting for Interiors

For people thinking that the above renders look too noisy for their uses.. then I would just change the noise threshold from 0.01 to something lower. The renders are just for comparison purposes. When I do high res renders, like over 5k, I sometimes even increase the noise threshold to 0.02. I never do animation work so have no experience with having to output super clean renders so please bear that in mind in the comments. Notes on render times All images here were rendered at 1024 x 576 pixels, but on TWO dual xeon workstations. Addendum 1. 3ds Max: Working with big scenes.

3ds Max: Working with big scenes

Click on image to enlarge Introduction Based on the statistics on our site the visualization we make is more often designed for big residential complexes and villa communities. Sometimes these projects consist of dozens of multistory blocks, and the 3D-scenes include great number of greenery, automobiles, people and other objects of fillings. Most of all, our clients don’t have the ultimate version of materials and that is why we have to make such-like projects upon the conditions of numerous corrections and alterations. The most frequent question we’re asked: "How do you render such tremendous scenes? The answer is: No, the hardware we have is common as dirt. We do not work on anything that cannot be seen by camera in the sceneWe organize our projects and workflow. After reading this article, it can seem to you that these rules just slow down the work.

Hardware configuration. V-Ray Render Optimization. Intro This tutorial attempts to cover the process of optimizing your V-Ray render settings to get the best possible render quality and fastest render time for a given scene.

V-Ray Render Optimization

There's often a lot of confusion surrounding V-Ray's sampling methods and what 'ideal' settings are. Many times you'll see artists adopt the 'Universal V-Ray Settings' of having the Image Sampler (Anti-Aliasing, or AA) Max Subdivs value set very high (like 50 or 100), and then simply lowering the noise threshold value until the render becomes clean enough - thinking that it's the best / fastest that V-Ray can do.

As I have mentioned in previous posts, I am going through a process of updating old skies that feature a strong sun to include a new alternative version. When shooting HDR skies, it is very difficult to capture the full dynamic range of the sun as it is so incredibly bright. To combat this, in the past (following on from Bertrand Benoit's lead) I adopted a workflow that involves lowering the gamma of the HDR to make the bright parts of the sky brighter. This method has its drawbacks though, mostly in that it makes the colours in the sky a lot harsher, and sometimes makes the sky appear too bright in relation to the sun. Unwrap Techniques.

Tutorial / Random object visibility in 3dsmax with MaterialByElement & Opacity

This simple 3dsmax technique is quite useful when you have to trigger the visibility of numerous objects. Instead of deleting “randomly” some elements, you apply randomly materials that are visible… or not. This is a very simple flexible method, and it works normally with any rendering engine inside 3dsmax. It doesn’t involve any script (although I think it can be improved with scripts) We’ll take this 3D array of cubes for example, collapsed in the same object. First we appy on it a Multi/Sub-Object material composed of 1) whatever base material you like and 2) a material with a plain black color in the opacity slot (We do it in the example with VrayMaterial + VrayColor but it normally works with any material with an opactiy slot) Then you apply a MaterialByElement on the array and you choose the This is very flexible because you can choose directly in your viewport the distribution and the frequency of the voids.
