<member name="rendering/textures/default_filters/use_nearest_mipmap_filter" type="bool" setter="" getter="" default="false">
If [code]true[/code], uses nearest-neighbor mipmap filtering when using mipmaps (also called "bilinear filtering"), which will result in visible seams appearing between mipmap stages. This may increase performance in mobile as less memory bandwidth is used. If [code]false[/code], linear mipmap filtering (also called "trilinear filtering") is used.

<member name="rendering/textures/lossless_compression/force_png" type="bool" setter="" getter="" default="false">
If [code]true[/code], the texture importer will import lossless textures using the PNG format. Otherwise, it will default to using WebP.

<member name="rendering/textures/lossless_compression/webp_compression_level" type="int" setter="" getter="" default="2">
The default compression level for lossless WebP. Higher levels result in smaller files at the cost of compression speed. Decompression speed is mostly unaffected by the compression level. Supported values are 0 to 9. Note that compression levels above 6 are very slow and offer very little savings.

<member name="rendering/textures/vram_compression/import_bptc" type="bool" setter="" getter="" default="false">
If [code]true[/code], the texture importer will import VRAM-compressed textures using the BPTC algorithm. This texture compression algorithm is only supported on desktop platforms, and only when using the Vulkan renderer.
