Viewport material view I'm wondering why viewport material shading would draw an image texture fine, but doesn't seem to be able to draw a procedural texture:




The same is true for texture shading. Is it possible to get procedural textures drawn in the viewport without having to render?
No.

This is because the procedural texture is actually calculated by the render engine. The closest you can get is by "caching" the texture to a conventional raster image via texture baking, then using that as you would any other image texture.
