.dds mipmap viewport render in max.. how?

deohboeh

I am quite confused.. I have a mipmap http://www.crazybump.com/MipmapTest.dds.zip
that i took from http://www.polycount.com/forum/archive/index.php/t-60842.html
the concept is that the colours will change with the distance from the camera according to the mip map level(?)..
i am trying to render it in viewport and render it as image through mental ray.. It wont work.. it wont change its mip map thingie in viewport or render.. I changed to d3d, opengl same issue..
I made mip map look at linear nearer no change..
I need some help please i have been searching all day to no avail.. please help..
am using 3ds max on a macbook pro 15” 2011(late) through bootcamp.. ati6700 HD intel i7

Have you tried Xoliul's shader? (I don't know if it'll work)
You can always export it to Unity too.

If you're pressing F9 or using the Render menu, it won't work. Mental ray is an offline renderer, which won't load mipmaps from a texture file. This will only work in the viewport. You can use the Make Preview to render the viewport out to a file. Or you can use a Maxscript that lets you render a preview larger than your display resolution, if you want a really big image.

Here's an example I made a few years back, with a similar test texture.

I have downloaded xoliul's shader.. i havent tried it yet.. but the main aim is to be able to view this texture in the 3ds max viewport...
which i cant seem to be able to do...

I am just trying to view the texture on the 3ds max viewport... I changed the viewport driver from nitrous to direct 3d to opengl nothing seems to be working at mipmap look at set to nearer or linear.. all i get is red..

Eric Chadwick

Can you post a screenshot?

Eric Chadwick

What shader are you currently using?

Eric Chadwick

Mipmaps don't work with Max's standard materials, unless you have Show Hardware Map turned on... this button here:



And this won't work with mental ray materials. Must be a Standard material only (or a Multi/Sub-Object with Standards in it).

deohboeh

I put it on direct 3d with mipmap look up with standard map on hardware map on... No change...
I have shader as in? Everything is default 3ds max 2012

Eric Chadwick

Try this... in the Configure Direct3D dialog, in the section Download Texture Size, turn on Match Bitmap Size As Closely As Possible. Then reload the bitmap. You might need to close and restart Max to get it to reload properly.

deohboeh

Nothing changes.. I changed match texture size as closely as possible but it reverts when i restart.. so does mipmap lookup... reloaded the texture no change...

Eric Chadwick

Oh wait, I forgot this is a Mac! Direct3D doesn't work on a Mac, only OpenGL. I wonder if that means a DDS texture won't work... You're probably out of luck.

Direct3D doesn't work on OS X but works on Windows 7.. .dds should work on opengl too..
