i am sure that if vray - exe is published then there will be plug-ins for many 3d packages.
if there is a Vray.exe , then , it is just a thing about implenting the standalone - programm into you 3d - application with a (more or less) complicated plug-in.
developing a standalone raytracer has to be planned very well , and a very difficult process. but developing plug-ins for the application is then rather easy .
You can write an exporter from c4d to the vray scene file format, which is a text file that you can hand down to the standalone version of vray. There will be more info on that soon.
the vray-fileformat is exported from any 3d-application ( if there is an expoorter ) . the vray-format is a new fileformat which , similar to FBX*format or *.max(3d studio-format) , has all needed information inside:
camera-movement, objekt-geometry, UV-sets and texture linking . lights and their information (intensity, color+ special attributes for advanced lightning). skeleton animation , vertex animation, different possibilities for binding objects , “baked” information on dynamic objects. it will be ( i guess ) like a shading-language describing all kinds of happenings in a scene (like a artificial studio) and their materialinformations such as reflectivity of objects and so on…
you can programm (develope) the plugin for cinema4d , then - of course - you can simply generate a picture by clicking on the render button.
potential coders can ask (i guess) to participate , if they are experienced plugin-coders for their favorite 3d-application … make this world dream :idea:
