Hello everyone,

Just wanted to ask if texture resolution affects rendering speed ( considering that we can set mentalray to get textures from hard disk intead of ram)?

So is it a good idea to use all my textures at a large size irrespective of whether characters are up close or far away in the scene?? Also, if a am using the same image file as color maps in multiple shaders, is it going to be less expensive than using multiple image files? Similarly, is it less expensive to use the same shader instaed of multiple shaders on multiple objects??

thanks in advance. :)

Memory usage shoots up when using high res textures.
I would suggest converting your textures to "mipmap" , this creates massive files , but it holds a hierarchy of different resolutions in one file , so for far away characters , it would use a low res version of your texture , and for close up characters it would use the high res.

Not sure about render times , but it is definitely more memory efficient.

Read up on mipmaps (Maya help) , it will change your world!

Cheers

thanks a lot derik,

didn't know about mipmaps.sounds really cool.seems it'll save me tons of work of manual reasizing.will check it out.thanks again
