Performance Tips

This section will cover a few Performance tips.

• Using caching is very important to save performance. Even if you have to exclude layers for some special effects, use caching !

• Avoid using a Metalness map, as it will require processing of the Sub-Layer to be done even though it may be cached otherwise ! It's as heavy as excluding the layer !

• If your Sub-Layer is uncached, be careful of how many features you enable in the Material Options. Some like Triplanar will require the material to be sampled multiple times, or UV Variance will also sample additional textures and will make the Sub-Layer more costly overall. However, if the layer is cached then this is a non-problem.

• If you are using Tessellation, use the Quality setting to adjuste the strength of the nearby Tessellation.

• If you want to use a sub-layer only in a specific place, avoid using a Mask. Just paint it, and it will be calculated only in the landscape Chunk it appears in. (Sub-Layers calculated on specific chunks like this have their toggle in White in opposition to the blue ones which are calculated for the whole terrain.)

• See the complexity below :

This chunk is the only one affected by the difference
