Good catch, yes we are missing color space assignment on color textures in MMD loader.

I tested locally with a PMX file. Using SRGB color space looks fine.

Thanks guys. It looks better (more color now) but it still looks a bit light compared to the rendering in r92. Not sure if this is the intention? See the following:

@jasondalycan the renderings above appear similar enough to me that they may be caused only by lighting and not color management. Some adjustments to lighting are to be expected, given changes in the past few releases. Adjustment to renderer.toneMapping or renderer.toneMappingExposure may be worth trying as well, but less likely in this case.

If there does seem to be a remaining color management issue, I think we would need an example (model) to investigate it.

Ok thanks I'll work with adjusting lighting settings and report back if any additional findings. cheers

By any chance did you find a fix for this? Almost a year later I keep observing the washed out colors, even with lighting on/off.
