Hello.
My current model is around 15 million polys and I’m wanting to render it with Cinema 4D version 10.
My question is I have no idea where to start.
I tried exporting some subtools as .obj files and they rendered nicely in C4D but obviously C4D can’t handle all the 15 million polys at once.
If anyone can give me some ideas I would be grateful.
Cheers!
I don’t use C4D, but I’d bet finding a way to do sub-pixel displacement, or out putting a smaller mesh with a normal map of the finner details would be the way to go. Even in XSI, unless you have an Uber computer and/or video card, loading a 5mil model can put a cramp in your style in my experience if it has UVs applied etc. XSI is supposed to be one of the best in these regards…so
I’d start at say 3mil If you have to and try and import that if you have to into C4D and see how that goes…then try higher and higher…
At some point though you’re going to reach the point of diminishing returns where a normal or bump map would make more sense.
Near the end of this tutorial it looks like it goes into Sub pix-

AS mentioned above, unless youre working with XSI and a decent system, you’ll have to go the Normal/Displacement route. Since Z3 is awaiting its Normal mapping utilities, youll have to make due with displacement. Aurick said the enhanced Mulit displacement utility would be available later this week.

am taking his word for that! lol
Ok thanks a lot for the replies.
I’m not familiar with displacements etc. Would it be hard to use that method with my current 15 million poly model? Am I right in thinking I lower the sub-div levels in ZB for a low poly model and then the displacement map would contain all the high def stuff?
Yeah. Im not familiar with C4D’s displacement capabilities, but yeah…you genrate a displacement map from the High res geo in Z, then apply it to the low poly mesh in C4d like a normal map that actually changes geometry.
In the “other applications” part of the tutorials section of this site, theres probably something written about c4D and Z2 thats still largely relevant.
