By setting shadowLength to 1, the length of the shadow will be equivalent to the distance from the light to each vertex of the shadow, in pixels. 2 will be twice that, 3 will be three times that distance, and so on.

To modify the variable, just do shadow.shadowLength = value;

Alright, thanks. I'm also having issues with soft shadows. On the documentation under the light types section, the direct light preview shows the shadow almost fading out into the light, and I've also seen this behavior in some of the test rooms provided. However, my shadows appear to have hard cutoffs instead (im using SHADOW_SOFT_TRANSFORMED) and don't fade out. (see img, i'm using a spotlight here but the same issue is still there when i do use a direct light)

Also, soft shadows with a low shadow length appear to not be completely softened, and only the vertexes of the shadow are not the edges in between, however I'm assuming this is intended behavior. Either way, how do I replicate the effect shown in the direct light preview?

This can be solved by setting the light's shadowUmbra to 1
