3ds Max texture colour or gamma exposure bug in viewport
polycounter lvl 8
I was texturing a model, when suddenly the texture quality in the viewport became really bad.
Here is an example
Inside the viewport: http://i.imgur.com/5rI45Qh.jpg
quick render: http://i.imgur.com/EhWV794.jpg
Notice how the dark brown parts on the window frame especially looks horribly
It has never looked that bad before, and i saw it change quality after i updated the texture.
I have no idea how to fix this, and i don't want to scratch my model completly

I tried following the post, but i can't configure the settings, and trying different drivers didn't help either.
It seems it only happens to jpg files, atleast for now. It looked fine at first, but then suddenly degraded to this quality. Not sure if it could happen to the png files aswell.
Also it's only this file/model, if i start a new project and put a jpg texture it looks just fine.
Thanks for the tip, i'll remmember that
I just recently begand at a 3D artist school for gaming, so far i'v been working on a small Unity game.
I know this isn't what this thread is about, but do you know if i should use PSD, TGA or TIFF files for game textures aswell?
Some game engines have trouble reading alpha channels from PSDs. If so, then saving your PSDs out as TGAs is a good choice.
Making those TGA files can be tedious though, since you are saving your textures constantly, so there are a bunch of Photoshop scripts to automate it... see http://wiki.polycount.com/wiki/PhotoshopTools#Export_Tools
For example, many artists build the diffuse map, normal map, and specular map, etc. all inside one PSD. This makes it easier since various details can be shared.
So then you need to split them out so the game engine can read them as distinct textures. Those export tools are really handy for this.
I guess i'll just stop using jpg's, and hopefully i won't get this problem anymore
What is your graphics card? If you're using a laptop, and you have both an integrated GPU (usually Intel) and a dedicated GPU (AMD or Nvidia) then you may need to force Max to use the dedicated GPU. The integrated GPU is usually too weak to handle 3D graphics properly, causing all kinds of errors.
Sorry, i didn't see your message.
Yes im using a laptop with both a integrated card and a Nvidia card, however i can't seem to change to my other gpu. I can't find anything besides the driver options where im using Nitrous Direct3D 11.
I can't find the change graphic mode in the Autodesk files either.
Im having this problem with both jpg, png and targa files now.
I tried changing from 16 to 8 bit on a texture, and the quality dropped. Not sure if it's the same problem though.

For me, the second link under See Also was all it took. I did not have to mess around in my BIOS.
16bit to 8bit is a different issue.
I already switched via the Nvidia control panel to the 3ds Max program, didn't help. Atleast not on the issue with the weird colours. But thanks for the help, i'll report back if i find a fix or something.
However, for the time it seems to only happen when i change my texture bit size in photoshop and save over the same file max is using.
What is the option you use to change the bit depth... what is the exact name in the Photoshop interface of the buttons you press?
Image > Mode > and then 8 Bits/Channel, 16 Bits/Channel or 32 Bits/Channel.
Does the texture look bad in Photoshop too? Or only in Max?
Changing to 8bpc will cause banding sometimes, but in my experience only if the file has really subtle gradients. Normal maps can get this problem for example, because they often rely on subtle gradients. Or if you have a layer which is mostly transparent, with very subtle colors, then this can be banded when converted from 16bpc down to 8bpc.
Take a good look at the layers you are using, and simplify the PSD. In general it's best to use as few layers as you can, don't over-complicate things.
Yea sometimes they will change in photoshop too, like colours will change. Im almost certain that is the problem, and if it is then im glad i atleast know how to deal with it now. Atleast it isn't a Max error
