A lot of the shaders used in the game are VT-only (short for Virtual Textures), meaning their textures can only be loaded via specially encoded .gtp files. Currently we can unpack and edit these but not re-insert them back into the game as VT’s or create custom ones without the setup and use of Script Extender (see guide [https://github.com/Norbyte/bg3se/blob/main/Docs/VirtualTextures.md here] if interested). | A lot of the shaders used in the game are VT-only (short for Virtual Textures), meaning their textures can only be loaded via specially encoded .gtp files.

Some shader configs allow you to create completely (or partially) transparent parts on armor/clothing without needing to edit the mesh. A standard one is:<blockquote>Materials\Public\Shared\Assets\Materials\Characters\CHAR_BASE_AlphaTest.lsf</blockquote>Any transparency is added via the Base Color map, by creating a white Alpha channel and painting in parts you want fully transparent with black (grey for partial transparancy). In the game files these files might be called _BMA instead of _BM, but the naming doesn’t matter - they’re just _BM files exported with Alpha active. | |||

A way to make your model appear double-sided without editing the mesh, is to use a shader config that allows for Backfaces. A standard one is:<blockquote>Materials\Public\Shared\Assets\Materials\Characters\CHAR_BASE_AlphaTest_2S.lsf</blockquote> | |||

You don’t need to do anything special when switching to this shader, the textures used within the materials will now just appear double-sided. Note that this one also allows for transparency, as a non-VT alternative just for _2s exclusively doesn’t exist for us to use. As long as you don’t have an Alpha channel in your Base Color Map it won’t affect your textures. | You don’t need to do anything special when switching to this shader, the textures used within the materials will now just appear double-sided.

=== VertCut === | === VertCut === | ||
Shaders with this term in their name allow for using vertex colors to mask parts of clothing. For example, a pair of boots are too long and clip through pants - a VertCut shader will allow you (with an appropriately set up model) to hide the part of the pants the boot overlays and avoid clipping. You can read more about them in general here | Shaders with this term in their name allow for using vertex colors to mask parts of clothing.

=== What if I want to use x and x? === | |||
Some combinations of the above are also possible, though again, we are limited by the amount of non-VT ones that allow for them. See the page [[Modding:Non-VT Shaders|here]]. | |||
Many more shader configs with specific purposes exist, you can always check within the shader config .lsf file to see what texture maps + parameters it allows. | Many more shader configs with specific purposes exist, you can always check within the shader config .lsf file to see what texture maps + parameters it allows. | ||
