Notice the gaps in the udder area, between the checkered sides and the brownish back part. If we re-load the cow model, perform 85% reduction and look at the cow's rear end we will find such cracking: Notice that the reduction algorithm has also maintained the overall texture mapping quality even though 80% of the underlying polygons have been removed.Īs explained throughout all of the polygon reduction tutorials, performing polygon reduction on multiple objects which are not pre-welded together can lead to cracking and holes in the final model. This problem will be fixed further into this tutorial. This looks fairly close to the original model except that the outline of the eyes have become smaller in size. This removes 80% of the polygons, leaving 1154 triangles: To make a quick test reduction, press the " Reduce!" button right away. Press the " Reset" button to reset all the options to their default values. The polygon reduction options dialog box will appear next. Now select the " Okino Polygon Reduction/Apply to selected instances only" menu item from the main menu. § Left click on the " cow" yellow folder, shown above, so that all sub-objects of the cow become selected. § Select the " Okino Polygon Reduction/Apply to all objects in scene" menu item from the main menu, or § Right click on the " cow" yellow folder, shown above, and select the " Polygon reduction" menu option, or To start the polygon reduction algorithm on this object, select one of these common starting methods: The cow model originally was imported as a series of distinct parts, as shown in this screen snapshot of the Selector Window: For this tutorial we wish to reduce the number of polygons in this cow object which originally has 5804 triangles: Polygon reduction is a mathematical technique whereby the number of polygons in an object can be reduced without significantly reducing the quality of the resulting model. This is the simplest tutorial in a series which shows how to apply polygon reduction to a cow model. Simple Introduction to Polygon Reduction: Reducing a Cow You are here: Home » Specialized Sections DWF for AutoCAD, Navisworks, Revit & Others.DWF (AutoCAD, Navisworks, Revit & Inventor).When the “Decimate” window appear, the polygon count is displayed. From the menu panel, select the tool to access the modifier panel. To reduce the polygon count of a model with Blender 2.7: Open the model with Blender then select the object polygon you want to lower. How do you increase your rank in VRChat?.
