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

roof - capacity problems

Hi there!

I'm having a capacity problem with my house project. I'm building a roof made of 1000's of small nurbs surfaces. They each have a UV span of 1 and 40. I've made one nurbs surface, and then instance copied it.

First problem:
The roof is killing the realtime renderer, even in wireframe mode.

Second problem:
The roof is killing the raytracer.


I really want to model each roof tile, and not use a texture.

My hardware is ok, but not in the professional league: 2 Ghz Athlon processor with a GeForce4 Ti400 (128 Mb)

I'm not very experienced, so maybe you could help me out on this, please...

Thanks in advance...

Kitoc

One thing that might help is a Level of Detail control type thing. For instance, the house far in teh background doesn't need to have each tile modeled... as you can't even tell! Same for the tiles on the opposite sides of the house that aren't in view.

One way to do this would be to control the transparancy of the tiles switching between the individual tiles and one large low-res mesh simulating the tiles. If you plan on animating the camera to zoom to other areas, you can key the transparancy of the two objects to switch places. It would be hidden in the movement and motion blur of the animation.

Hope that makes some sense...

The only other thing I could suggest would be to render the roof seperately and than compile together in an editing program.

Thanks a lot...

The problem is that I'm making a presentation-movie, which means that I can't presume anything about camera-placement. I want the entire model to be complete, so I'm able to mode the camera freely.

Is it possible to bypass the raytracing for the roof-tiles (render layering or something?)

I appreciate your answer mtmckinley =)

Doh! Now I finally understand what you were saying in you reply, mtmckinley =)

Is it possible to do that LOD-thing automatically, so I can move my camera freely?

You can use Set Driven Key, so when the camera gets to a specific distance, it switches between the two.
