ix. Let’s make a preview look of the BerconNoise map! Launch the TextmapPreviewUI shortcut that you created in Step 1. It is shown to the right.
Basically what this tool does is it will display whatever texture you have selected on a selected model, as it would appear at render time. This is super useful for procedural materials as they will not render correctly (or at all) in the Viewport. Under “Which Objects” you want to make sure you have “Selected Objects” selected. Under “Which Map” you can choose to lock a map you have selected, or it will choose whatever map you have selected at the time. NOTE: This tool will render ONLY the object you have selected.
Self Illumination can be adjusted to make the texture more or less clear.
Finally, under options you want to either set it to Render Current Viewport or Render Locked Viewport (controlled in your render settings). You also want to make sure that “Use Slate Mat Editor” is selected.
Hitting “Do” will run the tool and close the window. Hitting “Apply” will run the tool and keep the window open. We recommend you mostly use the latter.
