Support for DDS? PNG and TGA are great but don't support mipmaps.

Trying to mod the new yugioh game.

For importing or for exporting? UABE normally generated mipmaps for png and tga files so they didn't have to be included with file when importing. UABEA doesn't support mipmaps at all (even when reimporting) although that will be added soon (hopefully). If you need them for exporting, then that's probably a valid reason for dds, although ImageSharp doesn't support dds right now.

For the edit texture plugin. Loading textures on the Texture2D type.

[nesrak1]

Are you okay with uabea generating mipmaps for pngs? That would make things much easier.

[fuwafoowa]

I am I think... I'm not too savvy about any of this. I just know I need mipmaps haha.

UABEA doesn't support mipmaps UABE normally generated mipmaps

As far as I remember (I do not have the UABE source code now) All PNG's converted to DDS with DXT compression + mipmaps generating and all it depend on asset's setting for each textures while importing (used PVRTexTool Library) Also DXT1-5 depend on alpha type (may ignore asset's settings) Export or import DXT compressed DDS it makes no sense, because with each DXT recompressing operation the quality will be lost

PNG - the best solution Never use TGA (often editors uses non standard RLE encoding and exiF table) There may be unpredictable consequences when importing targa images

UPD: PVRTexTool Library should build mips by default for PNG->DDS (while importing to assets)

UDP (offtop) Possible issue: Need excepting exporting some DDS textures (3d\cube, but stored as 2D) Exporting and reimport will broke this textures.

When I have time, I'll take a look and report what needs (may not need anything)

textoolwrap.cpp

crn_mipmap_params mip_params;
mip_params.m_gamma_filtering = true;
mip_params.m_mode = cCRNMipModeNoMips; //cCRNMipModeGenerateMips

Need check for m_mipCount in Asset Data for current texture m_mipCount = 1 then mip_params.m_mode = cCRNMipModeNoMips (no mips) m_mipCount > 1 then mip_params.m_mode = cCRNMipModeGenerateMips (rebuild mips)

Thats all

• No mips for all textures - performance lost and more vram usage (actual for 3d games)
• Force mips for all textures is not good idea, as this greatly increases their size (so we need to check source mip settings for each textures, before import PNG->DDS)

@nesrak1 Hey, sorry for the ping, but is this still a planned feature? Kind of need it for a project, and this issue looks rather stale.

[nesrak1]

It's definitely a planned feature and I've even started work on it (but not pushed it). I had a few issues with certain texture formats and I haven't touched the code in a few months to fix it. On top of that, I added switch texture support which might complicate things a bit. I'll make the priority on this feature higher (hopefully to make it into next release.)

School has started up again though, so I'll be a little short on time...

Thank you, I really appreciate it. It's a really essential feature if you want to mod 3d games :D.
