Just a short video trying a bit more on Blender, this time using UPBGE to see if it managed better performance, which i'm not sure it did, the viewport was at 60 fps but went down to 2 every time i changed a material property or scrubbed trough the timeline, rendering on EEVEE at 720p gave me an average of 2fps when rendering with settings far higher than on previous videos, the part where the model removes its panties was made on the spot with 5 Shape Keys (Vertex Morphs in MMD language), also used keyframing on materials to hide parts, but it seems that the DOF still sees them as opaque, also noticed an error on the scale of the skin material on her breasts after rendering, so i didn't bother fixing it, there is no HDRI nor sun light on this video, instead its all in the dark other than the small lights around the character, i made the stage look like its on day time by adding emissiveness on it.
