Disable texture filtering with Nitrous in 3DSMax?

PolyHertz · May 2013

I was wondering if this is possible? It's one of the main reasons I use Direct3D instead a lot of the time, but the viewport runs much smoother with Nitrous on my Geforce660, unlike my old card, so I'd like to avoid jumping between them.

I'm running Max2012 but it's fine if its only on 2013/2014 as I'll eventually be upgrading anyway.

bump.

Having the same issue here: i'm using Max 2014 with Nitrous Direct3D 11 and I can't get the textures to load with full resolution. Would really appreciate some help.

Thanks!

Update: Apparently, one cannot access the Nitrous texture quality settings without the use of scripting.
I've found a really cool script on ScriptSpot, with which I resolved the issue in a matter of seconds. It lets you adjust the Texture Size Limit within the viewport.

HERE is the script.

There is no way to turn off texture filtering with Nitrous. Sorry.

There are a couple of ways to see the full resolution of your textures.

Change the viewport shading to Realistic. In the viewport dropdown choose Materials > Realistic Materials with Maps.

Or you can try this script.

The posted script seems to have problems with Max 2013
Here's a script that is compatbile with Max2012/2013/2014 and provides some more options..
Nitrous Texture Tweaker

But:
filtering in Nitrous cannot be controlled, as monster already stated
If you are brave, you can use tools like "Nvidia Inspector" to enforce some filtering options. I did not really test this with the aniso/mipmap filter options but AA options etc.. can be forced for nitrous with this tool

Bump.

Any changes with Nitrous in Max 2016?

Noors · Oct 2015

Nope. Still have to switch to legacy directx.

jRocket · Feb 2019

Bump. Is this supported yet? I'm running in legacy d3d to get around it, but the uv editor crashes all the time.

I just checked the brand new OSL bitmap in 3ds Max, because OSL has texture filtering in the spec. It compiles, but doesn't display with filtering disabled. Sorry.

Bumping this topic because AD seems to be working on improving the viewport lately:

Anyone know if this age old issue is finally resolved, or is at least on the roadmap?

---UPDATE FOR ANYONE WHO FINDS THIS THREAD---
This issue can now be resolved by creating a ShaderFX material with the TextureMaps "Sampler / Filter" property set to "MIN_MAG_MIP_POINT". This setting used to be broken in ShaderFX but apparently it got stealthily fixed in one of Max 2018s updates.

Hey, looks like that works. I've never messed with ShaderFX at all, any tips on how to get this unlit/flat shaded?

Yep, just plug your map directly into emissive, and set MaxNumberLights to 0.
Alternatively, here's the FX file I made for retro stuff (supports unlit + unfiltered textures, as well as vertex colors, tiling, and vertex alpha opacity): https://www.dropbox.com/s/0har718krnizic5/3dsmax_retroShader.fx?dl=0

Justin Meisse · Nov 2020

Awesome, that works perfectly! The reason I couldn't just switch to legacy DirectX is because it doesn't seem to work anymore
