I have imported raster images from photoshop to CTA5.
I have imported SVG from illustrator to CTA5
Today I have managed to import svg from Animate> illustrator> CTA5.
SVG is working just fine.
It is how you create a template and name the layers in the outside software that matters more.
If one word or letter is missing in the layer names of the template it is not going to work.
I am not so sure about Inkscape and other software because I use Adobe products, and even with that, it takes hours to create a custom template properly rigged.
Search for online tutorials. Rigging in CTA5 is a bit different than in CTA4, so that could be an issue as well.
Check out tutorials on 2danimation101.com. I got the courses for free with CTA5 and it has really helped me a lot with this rigging part.
