I loved using CSP's vector tools for my web comics...it makes it so much easier to edit things or re-purpose items at different scales...but, yeah, I don't think I tried exporting SVG from CSP. This was mainly because CSP's vector tools are primarily designed for linework, not fills. (TBH, it's been a while since I last drew a comic in CSP but that's how I remember it.)
So which vector programs do work well with Moho?
When I was busy on
Fast & Furious: Spy Racers, I used
Adobe Illustrator to create a lot of screen graphic elements as SVG and imported these elements to Moho, but whenever I animated a 2D story segment in Moho for
Fast , I was using either bitmap art (usually from
Photoshop provided by our art department,) or vector art I drew directly inside Moho, or a combination. Based on comments elsewhere in this forum, another popular vector drawing program that works well with Moho is
Affinity Designer.
I imagine almost any drawing program that has full support for vector strokes
and vector fills,
and can export SVG, should work with Moho. Moho also supports .ai format but I don't think this as reliable as SVG because the import process alters the construction of the paths.
As mentioned earlier, if the intent is to create vector drawings for bone rigging and deformation in Moho, the best results come from using Moho's Add Points tool. And if you're going for a 'painted' or 'photo-based' look, bitmap with custom warp meshes created in Moho is the way to go. And you can always combine the two: for example, create a path with a vector brush stroke and use Image Texture to apply a bitmap fill. My old Moho work for
Puss-In-Boots and
The Croods was created this way. (
My 2017 reel has a lot of these vector-bitmap hybrid examples.)
For painted or otherwise bitmap images to use in Moho, the popular programs are Photoshop, Krita, Clip Studio Paint, and ProCreate. (Note: Krita is free (donations accepted,) and ProCreate is iPad only.)
Hope this helps.
