Texture Importer
To import textures using Toolkit, you'll need to access the Texture Importer context menu.
There are 3 ways to access the menu:
- Selecting it from the top bar under Tools -> File Utilities -> PNG/JPG to TEX will allow you to choose an image and export it to an external .tex file.
- Right clicking on a folder with New -> Resource -> Texture will add it to a .farc you choose and prompt you to set a filepath and GUID.
- You can replace an existing .tex file entry by right clicking it and selecting Replace -> Image.
The texture import menu has several options, but generally you'll leave them unchanged.
- You'll always want to leave this field as DXT5, but the option is there if you'd like to use the other formats.
- DXT5: Supports full range of color on the Alpha channel.
- DXT3: Supports limited range of color (4-bits) on the Alpha channel.
- DXT1: Supports limited range of color (1-bit) on the Alpha channel.
- If the texture only uses brightness and alpha; this is primarily used for bump maps, as they're used to calculate height instead of storing color.
- LBP2, LBP3, and LBPV use GTF for their textures, so you'll want to use this for those versions of textures.
- Icons in the popit will appear clearer when this is used.
- Adding mipmaps to the texture will add smaller resolutions of the image with lower detail for when the texture is far away; this saves on rendering memory.
- Generally you'll want to leave this checked, but if you have a particularly large texture this can save on filesize.
Texture Standards
- Imported textures need to have dimensions with a power of two; 32, 64, 128, 256, 512, etc. but they don't have to be square, so you can have 512 x 64 for instance.
- Unless you're disabling mipmapping for the texture, you'll usually want textures to be 512 or lower since the game will default to using 512 when possible on larger textures.
- Bump maps are LBP's equivalent to normal maps; they serve the same purpose but save on space for the cost of minor detail.
- To create a bump map from a normal map you can either convert it using bog's tool normal2bump, or you can separate the texture fields using the image program Gimp.
- The brightness (RGB) fields of a bump map are used for the Y-Axis, with highlights on the top and darkness on the bottom.
- The alpha (A) field of a bump map is used for the X-Axis, with highlights on the left side and darkness on the right side.
- SDF images, or signed distance field images, are used for the game's UI since they can be resized without losing much detail.
- As of yet, there is no support for importing SDF textures or textures that are stored in a 32-Bit format.
