ConverterPIX - Game formats to middle formats

[Takahashi]

... Wow... I spent my whole summer trying to convert my truck to the middle format, and I only got the interior fully done. With this tool, I seamlessly converted the interior and exterior in ten minutes... (even though the emoji looks sad, these are tears of happiness lol).

Thank you very much for this tool! If this forum were to have a post-liking capability, I would like this thread too.

=========================================

EDIT: I do have a question though. When I import my middle-format truck into Blender, I notice that there are no lamp materials. Is ConverterPIX supposed to convert the lamp materials, or no? I have my hookup and material.db in my base directory, and set in my Blender Tools.

Hi Mwl4! You can would you put the versions in convertpix (example: ConverterPix1.27.2)? Sorry bad inglish, God Bless!!!

Hey mwl!

I don't know if you are aware of it, but every time I convert a model with your tool, the values for the specular levels are not the same as in the material files. The values of the specular levels are always closer to 1 than the materials they are based upon. For instance, a material with specular levels [1.6 1.6 1.6] has after conversion only a specular level of [1.24 1.24 1.24]. This works the other way around to (lower values end up higher). It seems that we're dealing with a non-linear effect. All other material values are copied appropriately however...

Could you investigate what goes wrong here?

and mind you, that MAT files are using linear color space where PIT files are using sRGB color space. And there is more! This only applies on values representing colors. For example "shininnes" and "add_ambient" attributes are not part of this.

Yup. If you convert that back to binary format via SCSCT, the material values should come out correctly (± some amount of floating point conversion error). It confused me at first too. Still not as bad as how long it took me to realize that the UI colours are in ABGR.

As the predecessors wrote, converter converts linear color space to srgb for "ambient", "diffuse", "specular", "tint", "env_factor", (also there should be water aux converted, however I am not sure how exactly it should be).

Here are conversion functions:

Code: Select all

/**
 * @brief: Converts srgb to linear color space
 * 
 * @param[in] x The srgb value
 * @return @c The linear value
*/
static float s2lin(float x)
{
	const float a = 0.055f;
	return ((x <= 0.04045f) ? (x * (1.f / 12.92f)) : (pow((x + a) * (1.f / (1.f + a)), 2.4f)));
}

/**
 * @brief: Converts linear to srgb color space
 *
 * @param[in] x The linear value
 * @return @c The srgb value
*/
static float lin2s(float x)
{
	const float a = 0.055f;
	return ((x <= 0.0031308f) ? (x * 12.92f) : ((1.f + a) * pow(x, 1.f / 2.4f) - a));
}

if you want to convert values for some reason (it might be useful when you want to put some mat values into blender).

Is there a log file somewhere?

[mwl4]

Not in the current version. Program print results on stdout. You can redirect it:

converter_pix -b "C:\example_base" -m "/model/example" >log.txt

Thanks!
