Conflicting "matcapFactor" default values in README

[kayhhh]

In both the English and Japanese README: https://github.com/vrm-c/vrm-specification/tree/master/specification/VRMC_materials_mtoon-1.0#mtoon-defined-properties-4

Table says default value is [0, 0, 0], but further down it says default value is [1, 1, 1]. The spec says it should be [0, 0, 0].

actually i can just make a PR

Thank you for the point out!

However, I think it's [0, 0, 0] instead. People might want to just assign matcapTexture and not matcapFactor, and it's gonna be a problem if the matcap does not appear in the situation. The matcap texture will be black if it is not specified, so it's fine to leave the default as [1, 1, 1] even if it's unused.

I was just going from the json schema, where it says [0, 0, 0] is the default.

I think you might be right that [1, 1, 1] would be a more sensible default. I can update the PR to use [1, 1, 1] if you'd like (and also update the json schema to match).

Even the schema is different! I see, thank you for the fix.

@Santarh just want to confirm that [1, 1, 1] by default is more appropriate, right?

[Santarh]

Looking good to me.

But this issue reveals more complex problem because of default value of matcapTexture is undefined. The problem should be discussed in another issue.

@kayhhh Would you change the PR to use [1, 1, 1] for now? We are going to address the spec side in the different PR.

ok, updated it
