Blender Transparency Map Shadows Quick Fix

Over the weekend I was working out how to tear a piece of paper in Blender and stumbled on the annoying but easily solvable issue of transparency shadows.

By default a material will not receive shadows based on the texture but on the geometry of an object. As seen here:


To fix this, go to the receiving material’s proprieties and click “Receive Transparent.”


Now the shadows are based on the texture:


A simple fix, but if you are coming from a 3d software using clip maps or settings on the texture this can be a bit difficult to find. I will be taking a closer look on how this effect is best used and if it affects render times in a later post.

Blender 2.5 Network Rendering: Part 01 Systems

This post is an outline for setting up an offsite render network mainly for Blender Rendering but also for After Effects and possibly Premiere. I had started a series on this before but ran into a number of problems, which have now been sorted out. The network has been in use for a few weeks now and consists of all of the major platforms; Linux (Ubuntu,) Windows (XP/7,) and OS X.

The main objective with this setup is to have a remote render farm where work is offloaded from the main workstation and left to work without constant management; however, variations based on individual needs this setup should be easy to do. I will be covering everything from the OS setup for easy remote management to Blender install and setup to terminal commands. I won’t be covering hardware setup, OS installation or general use for each program; there are any number of guides these so no sense going over them again, I’ll be sticking to what you need to manage renders in Blender.

Blender Network Rendering: Quick Update

I’ve noticed in the past few weeks the site getting more traffic and most of it to the Blender Network Rendering post, there will be an update on this soon. I wanted to point out that the tutorial series isn’t dead but it did end up going though major revisions when put into practice; the changes are mainly due to LuxRender being a bit too heavy for animation use and my workflow switching to Blender 2.5.

Animatic Builder Animation

Animatic Builder v1.40

Animatic Builder v1.40 - Auth: Whitney Krape The new version of Animatic Builder is up. This update includes a whole offline system taking advantage of HTML 5’s manifest and localStorage for offline use anywhere. To complement the new offline functionality is a redesigned UI which now scales to mobile platforms as well, specifically the iPhone. The are a number of speed improvements allowing well over 200 frames in a sequence without impacting playback performance. (The SQL updating and the uploading for the demo are disabled.)

Dynamically generated HTML5 manifests

In the specification for HTML5 several methods for storing data locally are outlined including localStorage and manifests. While building out the offline storage for Animatic Builder, I attempted to keep the stored data dead simple; as in the case of the shot information which is stored as one long JSON string. In this way the shot data can be pulled into any other use by reading the string. Keeping the images stored proved more difficult due to the number, potentially hundreds, and their format as many separate files. As well as making sure the storage is universal on mobile and full client systems.
