===== Decimate =====

==== Tris to quads ====

In edit mode (1), select Surface (2), then Tris to Quads (3). To ensure that all faces are selected, press A. This converts triangular polygons into squares and reduces the complexity.

==== Decimate ====

Decimate is a modifier that simplifies the polygons and complexity of the model to reduce the processing load on the computer. This step should be performed by [[en:blender:smoothing|smoothing]], beautify and shade smooth.

Switch to object mode(1). Then click on the spanner to open the properties of the modifier(2).

{{en:blender:reducing:decimate_2.png?direct&800|}}

Select "add modifier" (1) and then "decimate" from the list (2).

Here you can select the ratio of the decimation. For example .5=50% of the original model complexity.

In this case, the polygons have been reduced by half. Finding the perfect mix of reduced polygons and a beautiful look is a matter of experimentation.

To apply decimation, first click on the arrow next to the decimate modifier.

Click on "Apply" in the drop-down list to make the decimation permanent.
