Once the basic nodes are in place add another Image Texture node, Add » Texture » Image Texture. Set up an initial basic Material by dropping an Image Texture node into the Node Editor once a material is available or assigned, then set the ‘diffuse’ image using Browse Image to be linked or Open to use/load in a bitmap, which is then linked to Principled BSDF. ĭesign note: once set up the Material will only appear in Material Preview/Rendered display modes if the selected object has been UV unwrapped and mapped. Finally click-drag the Image Texture nodes Color output to the Base Color input of Principled BSDF. Switch to Shading Workspace and in the Node Editor (lower area) click the Add menu and drop an Image Texture node into the workspace, Add » Texture » Image Texture, then click the nodes Open button, browse to and load in a new image, or the Browse Image to be linked button to link an existing (previously loaded) image. To set up a transparent material governed by a separate image, first set up an initial but basic Material (select the object and) in Material Properties click + New to create and populate a new instance if one does not exist. Masks are typically black and white images, essentially a stencil or cutout, whereas a map might be more complex, offering degrees of opacity, and be fully grey-scale. Generally speaking then, transparency results from a process that ostensibly filters certain aspects of a material such that content can be seen through it, a cube placed inside another object being visible through the outer objects surfaces for example.īroadly speaking opacity maps – right, and opacity masks – left (also alpha maps and alpha masks), function the same way, both define areas of transparency or opacity. In some circumstances this can be confusing, especially so referencing external assets, tools or processes. In essence this is done by translating tonal information from an image specifically tasked for the job into transparency values – depending on the type of transparency being rendered, black equates to a surface rendered fully transparent, white fully opaque, grey being degrees of transparency or opacity in between.ĭesign note: the nomenclature used to describe transparency may differ depending on context, for example black values generally render fully or 100% transparent, which can also be referred to as being none or 0% opaque. In this context, creating materials that display some degree of image or object transparency, opacity maps, opacity masks, alpha masks, alpha maps et al are all functionally the same in that they provide Blenders node-based material system the data necessary to render transparency using separate instead of inclusive images ( i.e.

There is some cross-over depending on context, especially when assembled and/or used outside Blender.ĭesign note: materials that make use of a separate image to define opacity/transparency should render without issue in both main Render Engines, Eevee and Cycles, but may be subject to other limiting factors contributing to a given material instance or engine used to render.Ī simple opacity map based transparent material assigned to a Cube rendered in the 3D View using Cycles (note absence of sort-order issues common to Eevee). They do differ generally in that ‘maps’ tend to comprise more detailed and graduated grey-scale tonal values, whereas ‘masks’ are typically more oblique, defined by simple black and white values only. Important: in this context, using a separate image to generate material transparency (technically ‘blending’), ‘ maps‘ and ‘ masks‘ are essentially the same, they result in variable transparency (or opacity) of materials. One such approach is to use an Opacity Map, a separate image that defines material transparency.ĭownload: Opacity Map defined Transparency example file *.blend (c.200 KB). Despite the removal of the Blender Render or Blender Internal rendering engine from Blender 2.8+, there are still a number of straightforward ways to create node-based transparent materials and/or transparent objects ( transparent surfaces).
