LOW QUALITY RENDER

Hi, I´m a begginer user of corona, I´ve tried to render floor plan in HDTV, after many hours, quality of render is very low,. Size of render which I need is 40x40 cm in 300 dpi, for modeling I use 3ds max, can you help me? with render set up, it is very urgent, thank you, and sorry for interruption

Very comprehensive description this is not :] Could you at least attach results that you’re getting?

in the top menu:
Rendering → Print Size Assistant

This is horribly upscaled image. I’m not aware if 3ds max can upscale its renders in VFB, did you do that in photoshop? Anyway, 40 x 40 cm at 300 DPI would be 4724 x4724 px render. Open render settings>common tab and enter aforementioned numbers into output size field.

Then HDTV start to print in 300DPI ? I think you are new not only in corona =)

Please write what you exactly needed. And show what you have. Attached image not direct result it’s upscale picture not from corona but from photoshop cs6 according exif info
