Save yourself time by using the Renderpeople Resizer plug-inResize and relink hundreds of textures in your 3D scene within only a couple of seconds. Never worry about slowing down your system through lots of high-res textures again. And the best part is that it’s free for everyone!
Or use multires tx or exr.
I am not familiar with those.
So with either, you can run an image through a little command line utility. It creates a new copy of your image which has the original res of the file, a half res, quarter res, eight res and so on all the way down to a minimum amount of pixels you specify. When the renderer starts a frame, it looks at how far away something is and loads data from the file at a res that’s good enough for the distance from camera - it’s maybe adding some overhead to the render but it’s keeping your memory requirements lower. You use the vray hdri bitmap loader for each.
I’ll play with all of them.
The rule is exr is better for 16 bit + images like hdr’s and exr files that have float data, .tx or multires tif is better for things that started off as 8 bit images and don’t need higher colour depth.
The Renderpeople script is pretty slick. Basically, you select your texture from your scene, and pick at what dimension to optimize it. It’ll optimize the image, save as, and re-path.
This could be pretty cool for taking stuff to Unreal.
i dont think it gets any easier than this
