Heavy aliasing when rendering SVG

Hi there,
I am new to CTA, so hopefully this is easy to fix: I have imported a prop from an SVG file (created in Illustrator), it looks perfectly fine within CTA viewport. But when rendering it gets heavily aliased (jagged edges, see image on the left). For testing I have imported the same prop as PNG, this always looks fine, both in the viewport and in the rendering. I have also tried to activate Super Sampling. It gets better, but not as smooth as with the PNG. I thought using vectors would always be the better choice for image quality. Am I missing something?

I have rendered -  the robot as a vector image and it is not jagged at all.

Maybe when creating in illustrator, try to enlarge the vector image to a big HD size, you can always resize it in CTA5.

Even as PNG files, always use HD-size images, which can be scaled down.

Hello,

Thanks for the issue reporting.
Please submit a support ticket; we may need some data from you. :laugh:

Thanks for the tip Famekrafts, but it is already created with an artboard and export width of 2K, so that should not be the problem.
I have just created a support ticket with the SVG file attached, maybe you will find something.

Thanks,
Bob
