The examples below show a calculation of the raw size for texture with a resolution of 2000x2000px in RGBA (4 channels) mode with 8 bits/channel. Image file size on hard drive = Raw image size x compression ratio + additional file data Raw image size = Horizontal resolution x Vertical resolution (in pixels) x Number of channels x Color depth (Number of bits per channel) We can describe the size of the raster texture with the below formula: What does the raster texture “weight” depend on? They are saved on a hard drive as files in various formats like JPG, PNG, TIFF and many others. Nowadays, the most commonly used textures in 3d graphics are raster textures, created based on photographs or painted in programs like Photoshop or Gimp. With this knowledge, you get more creative freedom and tools for troubleshooting all kinds of technical issues which are part of a professional 3D artist’s bread and butter.Īs with our 3ds max render farm, the following types of textures are supported: It is a roadmap that helps you choose different image formats, bit depths, and color models. This knowledge is substantial for every CG artist. In this first one, we will talk about the theory behind digital images. Because of that, when rendering on render farms, large texture files can slow down the speed of uploading your project on nodes and opening your scene in a 3d application which can result in higher rendering time and consequently, cost. The overall space textures can take on a hard drive can be bigger than the scene’s filesize. Textures are one of the assets which, like geometry, may need a lot of a computer’s RAM, and to a lesser degree, their size and resolution can have an influence on rendering time. In this guide, we will focus on 3Ds Max textures. In the previous part of our guide to rendering series, we talked about optimizing scenes in 3ds Max through geometry.
