Performance Tips

Builder Interface performance tips

• Be sure to use the paths sourcing features in the settings to reduce the number of unneeded textures shown in the Asset Picker. That will improve the startup time of the Interface and show less textures that aren't need, so it's recommended for both usability and speed reasons.

Shader Runtime 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 or UV Breaking will increase shader complexity. However, if the layer is cached then this is a non-problem.

• Avoid using Nanite Displacement as it is very heavy on performance as of 5.4.

• 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
