New Post: Essential Materials for C4D • helloluxx - https://lnkd.in/gtcti98w Each material contains notes on how to use it! A super handy feature is that every material includes notes in the Xpresso node editor which explain how to work with each particular setup.  No more searching YouTube to remember how to wire-up a Falloff mask or render X-Particles Trails colours.  You’ve got this! Not just materials, everything you need. Another cool feature is that the set contains not only materials, we include the complete scene file required for that particular effect. For example if you need to render the Matrix Object and use the colour from your Fields, this requires not only the correct material nodes to read the colour attributes, but also the scene needs an RS Object Tag with the appropriate settings. These are all configured and ready to go. There are a multitude of effects crammed into these materials, create dispersion, absorption and sub-surface effects, add wear and tear or dust to your models. Need to render Volumes, Hair, Splines, Particles, Mograph, Sprites, Wireframe? No problem! For more information and to purchase learn. Redshift Essential Materials, please visit the product page here. Source link

We all know data footprints for 3d scans are just stupid huge. I've been experimenting with more web-based rendering and data formats. I know I'm late to the game, but it seems to me this hasn't really hit the #3dartist ecosphere as most artists will tend to use more traditional file formats for a number of good reasons (obj, fbx, exr, png, etc..). But I thought this was pretty cool: 3.5 million triangle OBJ file: 251mb ..FBX file: 60mb ..DRACO-compressed GLTF: 890kb. Basis/KTX2/UASTC compression is impressive too. These 3d web file formats are strong here, but man how I wish the graphics capability wasn't 10 years behind. WebGPU is on the horizon, but I'm not holding my breath.

Importance of understanding colour representation in digital media. Why use YCbCr when RGB is a highly effective way to represent images? 🤔 If we consider the diagonal that goes through the three dimensions of RGB space, commonly known as the space diagonal, we can identify different shades of gray, which are also referred to as the gray scale. It is important to note that for any point on the Gray scale, the corresponding values of red, green, and blue are always the same. By using 24-bit RGB, we can encode a whopping 16.7 million distinct colors 🌈. However, it is noteworthy to mention that the human eye can only differentiate between 10 million colors 👀. Here, the reference standard is the capability of the human eye. The human eye👁️ is more sensitive to variations in brightness ☀️ than color differences. Hence, RGB format is not necessarily needed or not the most efficient way to save or transmit the images. 😕 Disadvantages of RGB system: In RGB system, color information and brightness information are combined. Flexibility of YCbCr format. The key feature of YCbCr format is that the brightness of each pixel is encoded separately from the color information. This means the color information can be changed independently of the brightness information.
