Good lord...I went through and turned off all texture filtering and what a world of difference!  Why have we all put up with this for so long?  Why is it even there?

Crazy.

For some things it's handy, but for the most part I turn it off.  It would be sensible if it defaulted to None :) can take me ages to set up a new product if I am not paying attention.

John.

Yeah, I always turn it off. Still not sure why it's on by default. But then, so is Reflection_Lite_Multi which is also crap and which I also always turn off ;)

It is useful, if your texture is large compared to your image (in pixels) to prevent aliasing. You probably will not need it, if you are using a large rendersize and a lot of antialiasing samples. These however usually cost more time than a little texture filtering would. The difference is most noticable when the texture shows great contrast. In the attached image, the floor has filtering, the wall not. As one can see, the farther the distance, the smaller the patterns become, and therefore the greater the texture (512 pixels) is in relation to the image, so it can look unpleasing (nevertheless interesting) when the aliasing artifacts show up.

It would be nice if someone would do a script that turned filtering off.

It can be time consuming to do it by hand.

I've noticed with a lot of hair products my machine hangs if I don't go in and turn texture filtering off for each map.

Edited to say:As a texture maker/vendor, I am now creating all my textures with texture filtering off and oit hasn't effect the quality of the renders so far.

Don't hold me to this. I could be a thousand miles off.

My understanding is quality as the default renders quicker per a thread here a long time ago.

I think the script I have is by SVDL (sp)? that allows you to turn off filtering by selected figure, selected actor or the whole scene. Freebee here if I remeber right. I can check when I get home from work and supply more details if need be.

Be aware that rendering without texture filtering can be significantly slower, especially with large textures.

I've found that often hair tends to look better with texture filtering on than off myself.

Useful script by svdl:

A bit down on his newest freestuff page.

several scripts for that are available, try freestuff or python forum.

svdl made a script to turn it off ages ago, for Poser 7.  i don't know if it works in P8. 

Yes, most hair props do look better with texture filtering, but when I'm doing just tesrt renders I prefer them off.

In the final render, back on.

I'll check the links, thanks.

Is there a script to turn of Reflection_Lite_multi?

IIRC filtering is needed sometimes, but not always. It also looks beter if you use sinc filter rather than box in your render settings.

import poser
mats = poser.Scene().CurrentFigure().Materials()
for mat in mats:
    nod = mat.ShaderTree().NodeByInternalName("PoserSurface")
    inp = nod.InputByInternalName("ReflectionLiteMult")
    inp.SetFloat(0)
    mat.ShaderTree().UpdatePreview()
poser.Scene().DrawAll()

This will set refl lite multi off for all materials of the current figure

There probably one in freestuff, poser, utilities

markschum if that a pythin script? How do I use it? SOrry I know nothing of pythin scripts but click, click.

wow, this is an awesome demo.  Thanks! 

seeing before and after effects is a big help to learn this stuff.

Cool!

Sorry for my ignorance but what is bad about refl lite multi? and what is it to begin with... :biggrin:

create a new text document somewhere and rename it to something you can remember , like set_multi-off.py  then copy and paste the lines of the script from the forum window.  Use File, run python script to run it.

or download the attached file , and rename it to .py

Thanks markschum. One day I'll learn python. It's on my to do list right after vss, idl, and matmatica. 

actually, Matmatic is a Python interface to the material room.  you can't use Matmatic without learning Python.  it's really powerful.  i've been creating Photoshop blend mode functions from equations i'm finding online (and editing because they're mostly not entirely right).

thankls for the links RobynsVeil

so is this something to turn off before saving a mat pose for a figure?

Yes... I would turn it off by default for everything... whether mat pose or mt5 or whatever. You never want either of those on.

Quote - without it, Poser renders most hair textures pretty poorly, in my experience, unless at a higher resolution than my usual final renders (3600 x 2700) or a facial portrait at that resolution.

svdl made a script to turn it off ages ago, for Poser 7.  i don't know if it works in P8. 

It does, and in Poser Pro 2010
