Image Engine: 3Dc textures mips

[alvarome]

Hi:

Once more, I´m not sure where to post this because I have no idea if I am working with faulty textures (most probably) or this is a toolset bug (I hope is not).

I have a few ME2 upscaled 3Dc normals that all have one MIP less than expected. And that missing MIP is the 1x1 smaller one. That may explain why I have not noticed any vissual glitch ingame.

I loaded them in Stable 3.0 TPF Tools and after analysis those are not flagged. I´m unable to recall if this is correct -because these have equal or more mips than vanilla- or if should have been flagged because the mip count is not that expected for their size.

Those are installed anyway.

I loaded one of those 3Dc normals in Image Engine:

And, FWIW, this is the DDS header.

I tried to fix the mips using IE:

But the resulting image has a wrong number of mips too:

And this is the DDS header:

But a workaround that fixed it was to remove all mips using IE:

And, then, fixing that "no mips" texture with IE again:

So the new texture has the correct mips count.

I´m sorry to say I do not have knowlegde enough to determine what´s wrong in those textures but if anyone out there wanted to take a look, here you got:

I was aware of Mips issues in the past for V8U8 textures but these are 3Dc. I cannot tell for sure about it´s source but perhaps these came from faulty V8U8 ones. -?- No idea.

Any input will be highly welcomed!

Regards!

Think this is fixed now.
