Can there be Fish eye rendering ??

Introduction to Maya - Rendering in Arnold

This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

yes, select the camera, or create a new one (create>cameras>camera) , and open the attribute editor.......... go to the camera attributes tabby thing in the Attribute Editor.......... set Focal length to 15... and Angle of view to 100.3... that should work or you can set the Focal Length to less, to make the effect more Exagerated

and what maya doesnt offer, you can script easily in MEL or make a plugin in c or c++ (which is really easy as well, the plugging in part, cuz the graphics programming is a piece of hard crap)

For additional effect you could use mental ray with a lens distortion shader. There's one in Puppet's shaders_p pack here: https://puppet.cgtalk.ru/download/shaders_p_e.shtml

thanks allot. without proper rendering your image is never complete huh i mean a good model with no proper texture and no proper render is as good as a crappy model.
