Displaying Textures in the Hydra Viewer

If the texture maps used in your renderer's shaders are in the form of .tx or .tex files, you can show these in the Viewer, provided they have the file suffix .tx, rather than .tex. In addition, the Viewer can render RGB and RGBA image formats, such as .tif, .png, and .jpg. For example, create a primitive, assign it a Viewer shader material, and map the Texture parameter of the Viewer shader material to an image file.

Watch this short video to learn how to apply textures to your geometry in the Hydra Viewer.
