View Full Version : rendering while using large Texture files

I need to render an environment sphere for a panoramic shot. This is for film output, so we are using an 8K 16bit tiff with RLE compression that was stitched together.

Simply importing the file into a file texture node gives off a warning that its too big (200 mb). Has anyone successfully rendered frames using files this large? At this point we can render in maya software of MR...

The render simply aborts when doing this under maya... When I try from a dos shell, I get a warning saying the texture file is too big, and the render aborts... I've never had to deal with textures this big and I'm sort of on my own to figure this out... ;)


Any help would be appreciated.

Is your camera moving in the shot? If not can you maybe crop your image to only include the information that is necessary (viewable to the camera)? If not is there a way you could comp this image in post? Perhaps transforming the image to match the camera move etc. Maya does indeed crash when you try and use too large a texture. Perhaps you can break the texture up into smaller pieces and then apply them to different sections or the geo?

This image is a stitched environment, to be mapped spherically. I need most of the texture for sure, because of camera movement. Also, It would be very hard to cut the texture into smaller pieces and not run into seam or mapping problems...

My only hope so far is that 4k will provide enough resolution... I'm also going to look into exporting an MI or a RIB file and using MR or Rederman standalones..

If you can, I highly recommend you check out the follow Gnomon DVD by Eric Hanson. He talks a bit about hi res panoramic environments and how to get around Maya 8K texture limit.

- Just an idea.

We made a test in image.tex file format for renderman and even in 16k it works!

Mentalray would prefere image.map format.
Mayasoftware image.bot.
