Any 3D programmer anon know how I can get the right model to look like the one on the left? Left is how it's previewed in https://www.deviantart.com/sab64/art/MMD-Model-Roon-Download-970826887 and right is how my code is rendering it. I don't know if it's

Any 3D programmer anon know how I can get the right model to look like the one on the left?
Left is how it's previewed in https://www.deviantart.com/sab64/art/MMD-Model-Roon-Download-970826887 and right is how my code is rendering it. I don't know if it's the lighting or if I'm missing some fundamental concept in 3D rendering, but it looks so dull.
I have the texture and the specular map loaded. Does it look like it's a problem with the lighting, a problem with the specular, or something completely different? Or is it hard to tell just from the screenshots...

You need to enable toon shaders or whatever in MMD, it's been ages since I used MMD but if the shaders are missing, you just download and install them.

Shaders. The right one is closer to 'naked' lighting which is closer to realism, but anime-style aesthetics can't function in that environment. The left one still isn't full cel shaded, but you can tell that the face isn't responding to normals the way it's "supposed" to for a real 3D object.
2D faces can't exist in 3D space, so the two solutions are either extremely warped geometry or hiding it through incoherent shading.

Also the left might be using subsurface scattering to give it a softer look for the skin, but it's hard to tell from the image. https://en.wikipedia.org/wiki/Subsurface_scattering
But basically the main difference is shaders. 3D models for fantasy stuff hasn't changed much between now and the PS2, but the shaders and all the computational stuff they do are hugely different.

Thanks anons! Now to get into the math behind those concepts...

If you're going to work at building shaders then you'd better like math and physics, yeah. It's not modeling, it's programming. With lots of math.

Heh, that's what I'm here for.
The render on the right is something I'm working on right now; doing all the programming, math, and all that jazz. Was trying to make it look more realistic, but I guess that was not the way to go. Realism in surrealism.

That sounds absolutely miserable to me, but it's good that there are people with different mindsets. Shaders are one of the things that make games or movies stand out from others so it's probably a great skill to have.

>sounds absolutely miserable
It is miserable... Especially when you don't have a background in math. I'm learning everything as I go, not a moment I don't feel like an absolute retard. But then when it clicks, and that feeling of understanding makes it all worth it. I'm an addict and my drug is learning.

The static in her eyes actually generates a very quiet crackling inside my headphones when I open the image.
