hi,

I've got a scene set up with an hdri dome. I've checked the emit light box under the image based lighting tab, so my hdr image is my lightsource. The scene is not very eavy poly wise, but there are a lo of high res textures. About ten or twelve 2048x2048 tga's at 24bit. Also the hdr file is quite heavy, about 18meg.
I am rendering in MR and Final gather. I left all of it at the standard settings except the min and max radius which I adjusted according to my scene.
The rendering times I have are a bit too high, it's about 20 min per frame in 1280x720. As I will have to render about 1000 frames you can probably see my problem. I was wondering if the texture resolution has a big impact on render time, same with the hdr image?
Also is it possible that maya writes a cache file?

thanks
