Does DAZ Studio 4 (pro) use anything like Poser's Texture filtering?

McGyver

If it does I'm not seeing it... but that is no big surprise to me, because at the moment I'm googly eyed from checking for flaws in a model and going back and forth between Poser/DS4... and two, I am still extremely unfamiliar with DS's materials.
Thanks in advance for any info on this.

I've never heard that it has it at all, but I'm certainly willing to be corrected on that point.

I recon it does more than a few time I've seen in the render dialog box listing optimizing images 1,2,3 until it goes though all the images.

SickleYield

Ah-HAH. I didn't realize that was what that was!

Isn't optimizing just loading? All my textures are sharp by default. I know in poser you have to switch texture filtering off to get clear sharp textures. Where would you find this setting in Daz if it exists?

Yes it's a hard one you could be right to!
But it's crazy wording as optimizing and loading have totally different meanings, and if you can't turn it on or off than there's one point worrying about it anyway. Where's a DAZ guru when you need one LOL.

Optimizing images is running "tdlmake" on textures to make them more palatable to 3Delight. It is a speed/compatibility stage.

In other words, no filtering?

That depends on what options DAZ is sending:

Usage: tdlmake [options]  
  -envlatl         : build a latitude-longitude envmap
  -envcube         : build a cube envmap, needs six input images
  -twofish         : build a cube envmap from two fisheye images
  -lightprobe      : build a cube envmap from a lightprobe
  -skymap %s       : build a skymap using the given space/time coordinates
  -shadow          : build a shadow map from a zfile
  -dirtex          : create a "directory texture"
  -fov %f          : sets field of view for cubic envmaps (in degrees)
  -lzw             : compress texture data using LZW algorithm (on by default)
  -zip, -deflate   : compress texture data using Deflate algorithm
  -packbits        : compress texture data using Apple's PackBits algorithm
  -logluv          : compress texture data using 'logluv' algorithm (only valid with -float)
  -c-              : do not compress texture data
  -separateplanes  : write output file with separate color planes
  -smode %s        : s wrapping mode: black|clamp|periodic
  -tmode %s        : t wrapping mode: black|clamp|periodic
  -mode %s         : wrapping mode in both s & t
  -filter %s       : specify the downsampling filter (see -hh)
  -window %s       : specify filter's windowing function (see -hh)
  -quality %s      : quality mode: low|medium|high, default is medium
  -sfilterwidth %f : filter support in s (filter's diameter)
  -tfilterwidth %f : filter support in t (filter's diameter)
  -filterwidth %f  : filter support in both s & t
  -blur %f         : blur factor (>1 is blurry, <1 is sharper)
  -scale %f        : scaling down factor (must be <=1)
  -preview %f      : add a preview image with given scale or size
  -preview8 %f     : add an 8-bit preview image with given scale or size

'tdlmake' converts TIFF, JPEG, Radiance, OpenEXR, GIF, IFF, SGI, PIC, PSD, TGA
and bake files to 3Delight's texture format (multi-image tiled TIFFs).

EDIT to add

'-filter' accepts the following downsampling filters: box, triangle, gaussian,
sinc, catmull-rom, bessel and mitchell.

'-window' allows a windowing function to be applied to infinite support
filters (such as bessel and catmull-rom) to achieve a softer cut at filter's
support boundaries. Possible windowing schemes are: lanczos, hamming, hann
and blackman.

'-quality' controls the mipmap downsampling strategy: when 'low',
each mipmap level is created from the previous one, at 'medium' quality,
each level is created from the 2nd previous level and at 'high' quality
each level is created from up to the 4th previous level. The default
'medium' setting is more than enough for most applications.

'-skymap' takes a list of arguments separated by a comma in the following
format: latitude,longitude,timezone,day,time,turbidity
More about argument meaning and ranges can be found in the documentation

EDIT Again: The user can determine the filtering in the Advanced Render Settings under "Pixel Filter" in conjunction with "Pixel Filter Width (X)" and "Pixel Filter Width (Y)"

I was hoping that there was something the texture filtering quality setting within Poser's Material room (none, fast and quality).
On occasion I have noticed that certain triangulated polygons tend to blur or distort along the edge... often turning off texture filtering for that material and then rendering at a high quality will fix it.
For the most part this seems to occur far less with Studio than Poser... I just noticed something like that occurring in a model I made... I wanted to see if trying different settings would make it go away.

I decided to actually fix the offending polygon by going back and redoing that part of the mesh... It seems okay now.

Thanks everyone.
