material: ray trace glass

smr_VIZ · October 9th, 2007

Hi,

I did one exterior glass material based on Ted's tutorial idea. It contains fall off map, raytrace map and others.
For the small object testing, it looks convincing. But when I put it for large curtain wall, it takes foever to render.

I think I am not naive to the raytracing rendering. I experience main Raytrace lighting Quadtree Depth from 10 to 7. In the render scene pup up, under "Raytracer Global Parameters", I set Ray Depth Control's Maximum Depth to 2. Under "Global Raytrace Engine Options", I only left "Enable Raytracing", "enable self Reflect/Refract" selected. But it is still slow.

What else I should do?

I will post the glass material later if anyone want to see it.

just curioius...

what is your platform...
what you doing sounds like a processing hog

I have a slow pc also (at least for rendering ws)
so i avoid complex raytracing which is unfortunate

also, don't know if you are using daylight system.... if so turn the sky lite off this really adds time

this probably doesn't help much... but i feel your pain
