Fighting Compression in Blender German version Especially while working with selective color correction, you may quickly strech the heavily compressed material to it's limits. So, because of the low bit-depth and bitrates you will encounter annoying compression Blocks, primarily in the color components. Yet, Blender's compositor provides a little workaround to save the trouble: The Bilateral Blur Node. Though that name sounds quite complicated, the way it works is rather simple. It blurs the picture while trying to preserve important details. It is not that easy though, because Blender's internal computing in a linear, set-related color space will lead to the darker areas getting blurred much more than the rest of the picture and that's not what we want! Look, the traces of compression have vanished! Unfortunately this is also true for many details. Finally, we get a clean picture (Aside from the nasty web compression here ;) )
Small Blender Things messiahStudio Animation and Rendering Software Home | YafaRay Blur your Traces in Blender Gernan Version The last time I have explained how to hide compression artifacts using the Bilateral Blur. But there are many other situations which lead to nodes destroying your picture. Here for example: We see that a simple Hue Correct node may give us hell quite often! The Idea is to extract the change a node has applied to the image, do something with and then reapply it. This simple setup does exactly that: We subtract the original image from the output of our node and so get the difference. The artifacts have gone! That´s it for today.
Material World | Great 3D materials for blender News If you haven't seen Tim's Vermeer yet, go see it! It's about using technology to make great art. It's about persistence and plowing through an insane project one day at a time. Things every photographer and 3D artist can relate to. My friend Bob Groothuis, maker of the famous Dutch Skies 360 collections, actually played a vital part in this movie and was at the movie shoot in the Vermeer museum. Bob's been very busy. He just published Vol.5 of his Dutch Skies collection, with ... wonderful new HDRI containing all the golden light and fluffy clouds the dutch painters - including Vermeer - were famous for. We had a little chat about techniques and how he has streamlined his approach, and the result is that Bob sponsored this month's free sIBL-set and wrote this sweet tutorial for us. I still recommend reading my HDRI Handbook 2.0 (and working through the tutorials in it), but if all you want is a quick online tutorial, then listen to the things Bob has to say.

Setting Up A Render Farm What and Why? A render farm is simply a collection of networked computers that work together to render a sequence in less time. By dividing your sequence between multiple machines your total render time becomes a fraction of what it is on a single computer. Most production studios will fill huge rooms with server rack upon server rack, full of thousands of rendering computers (or render nodes as you’ll hear them called). A render farm can be a custom built cluster for a few thousand dollars or it can be a collection of arbitrary computers, a computer lab with networked stations, or you can invite all your friends over with their laptops. Blender makes it easy to take advantage of network rendering. I will be walking you through 3 stages. The second stage covers the networking process of connecting all the machines on a local network and controlling all render nodes from a master machine with VNC. Prefer to watch instead? Step 1: Building a Custom Farm Unit 1. 2. 1. 2. 3. 4. 5. 6. 7. 8.
Re-rendering GH House Hi, this time I invite you to create an exterior architectural visualization. The model that will be used is the GH House that you can download from the link here You will learn: - How to set the camera - How to set up outdoor lighting - How to arrange artificial lighting - How to provide the elements of nature - How to do post processing in Photoshop Category : Intermediate – Advanced Text version : Open a new file and change the rendering engine into Cycles Render Download 3ds file from Ronen website here Import 3ds file to Blender Set Units to Metric Tidy up parts that need trimming, as the pool area, the pole (the column house) and others. Create a plane, go to Edit Mode, on the Properties pane [N], check Length on the Mesh Display section The next step is scaling the whole object, but here we need a guide object to scale. Select all mesh objects except the plane object, then scale it until the chair dimension fit with plane object dimension. Focal Length is used for adjust the lens.
Surface Knowledge | mínima expresión Procedural Stippled Finish August 5, 2013 in Surface Knowledge by Juan José Torres You might have noticed the stippled finish in the background wall I used for my last scene. Stippled finish paint was very popular back in the eighties, so I created this material to get an old fashioned feel that would fit the vintage hardware portrayed in the scene.
