VP2.0 texture format questions

[szabolcs.horvatth]

Hi,

What is the most efficient texture format to use with VP2? Are there any preferences of file formats, bit depths, channel counts? Are there best practices and issues to avoid at all cost?

Maya used to prefer iff for textures to avoid internal conversion, but I doubt that its still relevant with VP2. Or does Maya read and process the texture file before sending it off to the GPU?

So many questions and so little information found in the documentations. 🙂

Cheers,

Hi szabolcs,

I think after loading into memory, the texture data should be same for the VP2. There may have some performance benefits for loading iff file, but once it is loaded, they should be all the same.

Hi Li,

Thanks for answering! I'm curious about the process that happens *before* the GPU receives the texture data. I'm not sure if the texture file is loaded by Maya (therefore going though the old school texture API preferring iff files) or is simply the file path passed on to a video card driver that does the file load and data conversion for the GPU.

So the main question is: what kind of format should I use to have the most efficient texture loading, with the least amount of data conversion?

Use .iff because Maya likes it? Use some special format that nVidia cards prefer? Use jpg or png because of the faster IO? Whats the VP2 texture magic bullet in 2016?
