Tutorial 4: Volumetric light
Some weeks ago, when a saw the marvelous tutorial of making of the “saint-benedict-chapel” at Ronen Bekerman site, I decide to try this for a scene I was working on.
It’s very simple and can be very effective. Using this method allows you to tweak the light. All you need to do, after finishing the whole scene, is as follow:
1.Make a copy of your 3d scene and turn off all the lights except the ones you want to effect the fog, like the sun in my case. If you are using a HDRI or EXR turn it off also.
(remember, turn off ALL lights except your main light source)
2.Apply a 100% black VRayLight material to the entire scene.(click on image for higher resolution)
3.Select (CTRL+A’) all the geometry within your scene and right click and go into the “Vray properties” dialogue. (click on image for higher resolution)
4. Finally you’ll need to go into the ‘render set-up’ dialogue and make a few changes.
-Turn AA filter OFF.
-Turn ON ‘Optimized atmospheric evaluation”
(click on image for higher resolution)
5. Now configure the ‘VRay environment fog’.
Below you can see my settings, it should work well for pretty much all scenes providing you have worked to real world scale. Press ’8′ to access the environment effects dialogue and enter the settings below, chance the settings to your taste.

6. Once you’ve done that, hit render – after some while you get this (as for my scene):

7.Now the fun part, go into your favourite postproduction program and apply the layer with a the blending mode set to ‘screen’. To tweak the the fog you can use the ‘levels’ tool to strengthen the intensity.
Raw render (nothing special, don’t you think so!)
After some corrections in Photoshop, you get this final image:
I hope this has been useful to you, if there’s anything unclear about this or you want to know more, fFeel free to ask me anything more in the comments area below. Thank you!

Tutorial 3: How to quickly make a 3d roof
ATiles is scripted 3ds Max plug-in FOR FREE for quick creation of tiles, paving floors, brick walls, roof tiles, fences and other objects of repeatable elements for architectural visualizations.

Tutorial 2 :Manually clear out unused bitmaps from memory
Using the MaxScript command below you can clear out any unused cached bitmap from the memory. Sometimes when you have been doing a lot of test renders and / or work on materials stuff gets “left behind” in memory. This command is useful to get rid of that:
Open the MaxScript Listener (F11) and type: FreeSceneBitmaps()
That’s it.
Tutorial 1:Composing your image
A quick way to help compose your images is to adjust your safe frame settings to act as guides in your vieuwport. For example, you can split into thirds for compositing your images.Have a look at the settings:
