Loss of quality in texture

Cadu · Sep 2013

I've been noticing that the textures to be put in the viewport are experiencing a loss of quality. In this image i tried to show what I mean.

It is a mistake when exporting or is a matter of size / resolution texture?

Thanks as always for your help.

looks like you've got some stepping going on. What format are you exporting as?

Dustinbrown. No, you dont need to guess that. I'm using 3dsmax/vray by the way.

MikeF. I using jpegs in 4096x4096. Painted initially in zbrush them exported to photoshop and 3dsmax.

yep, exactly what perna said. jpeg is just about the worst format you can possibly use for anything

Gamma issue as usual. Max convert your 8bit map to gamma 1 then "rescale" it to gamma 2.2. Gamma is vital for rendering and this is only a display issue, but once again a smart move from autodesk to activate this by default for people who don't know what it is for.
Disable gamma/lut correction.

But shutting down the gamma/lut correction wont turn off the linear workflow?

Yes it will.
Are you making renderings ? It should look fine then.

Actually, after a few adjustments i would render the scene.

Any way of working around that issue without turning linear workflow off?

hotfix4 for max 2011"Gamma: When using the DirectX display driver with Gamma and Exposure Control, banding could result in the viewport. This issue is resolved."

Well, obviously not Autodesk.
Ok, so tested with Nitrous, doesnt work either and i'm up to date on 2012
With direct3d, if you want the correct display, desactivate correction, if you want a correct render, activate it.

As long it affects only the viewport, should be ok right? Thx Noors.
