I recently imported a Daz3d Genesis 3 Character with clothes and hair into 3dexhange then into iclone7. I exported my final scene  in AVI at 3840 x 2160 and i notice in the "Render Export" preview the hair on the character is glitching, but if i were to export an MP4 at 1080, it is perfectly normal. Is it because the textures are not high enough to export at 3840 x 2160 or do i need to turn the hair into sotfcloth? Images are shown below. Thanks!

It might be a shadow bias adjustment problem -- would have to see the file to be sure.
