i made some new textures but it wont let me use them withought a rsr datei for poser 6 how do i do that ??? do i need a diff prog .. **huggles

RSR's are generally obsolete for any version of Poser above P4.  If the object you are trying to apply it toalready has an RSR, then delete it and try to reapply your new customized texture.

They are generally obsolete, but are used in full force by DAZ - one supposes as the widest support.

An RSR file is the 'file' version of a MacOS Resource (which is part of the filesystem on Mac, not a file) so that it can be used on Windows.  It contains information and data.  For Poser, this usually means thumbnail image data in an embedded PCT format - but can also have other information such as OBJ geometry for Geometries.

My question is this: how are you attempting to apply the textures?  An RSR is only required if it is a Material or MAT pose so that it is visible in the Library.  Even then, an RSR is only one form of thumbnail - Poser can also use PNG images as thumbnails - and if the texture information is in Poser format (PZ2 or MC5), it just needs to be in the proper location in the Runtime Library to be seen in the library even without a thumbnail... (?)  Otherwise, you can add texture images to an Image node by selecting it using the file reference on the node.

So, I'm trying to figure out why you need an RSR file.

Uhm, they aren't used by DAZ anymore either.  DAZ no longer supports PP and lower with the new products.

Okay, but that doesn't include V3, M3, D3, H3, A3, SP3, and the thousands of DAZ related content that still does.  The majority bulk of their products have only RSRs.  Okay, now they've flip-flopped and gone the other way - will they friggin' make up their minds! ;)

There are 2 ways you can apply your textures.

1.  Manually in the material room by going there. Select "Advanced" mode. Make sure you have the item you want textured showing in the drop down menu at the top on the left and whatever part of the item you want to texture showing in the drop down menu at the top on the right.  Right click in the working window, pick "New Node" and "2D Image" and then "Image_Map".  Then browse to your texture. Connect that node to the 1st and 3rd node of the Poser Surface window. Repeat for each part of the item you want to texture IE: head, hips, legs, arm etc.

2.  Use Mat Pose Edit  to create .pz2 files so that you can apply the textures from the Pose folder.

I'm not sure why you need an RSR for your texture, but to create an RSR from scratch:

1.) Get RSR Converter(At the very bottum of the page)

2.) In Photoshop(Or whatever...) create a 91x91 pixels image, and save it as a .PICT.

3.) Load your .PICT into RSR Converter, and export your .RSR.

Poser has stopped using .RSRs.  The new format for .RSR is .PNG.  To create a .PNG from scratch:

1.) In Photoshop(Or Whatever...) create and image, and just save it as a 91 x 91 pixel .PNG!  You don't need to save as 91x91 pixels, but the Poser library thumbnails are 91 pixels wide.  Sometimes you see thumbnails that are 91x182 that are interesting, but if you forget to resize then the Poser library WILL display the whole image!

Another quick way to get an .RSR or .PNG is to make a copy of an existing(to a seperate directory,) rename, and paste wherever!

=  )

Oh, now I understand why you need an .RSR, you do'nt know what one is.  Sorry, I missed the "what is and..." part of the title to this thread.  Actually, I think everyone did ;  .

A .RSR file is the file that Poser uses to make the thumbnails in all of the Poser Libraries i.e. Figure, Expression, Light, etc.  That's all they are, just a picture.  And whatever, library preset, file(.pz2 for Poses, .MC5 for materials...) has the same name as the .RSR is the file that get run when you double click the .RSR from a Poser Library!

Now what I said up top should be easier to understand.

BTW - RSR Converter is a free utility.  I should have mentioned that also.

Oh, and a good reason for using .PNG instead of .RSR is that Windows Explorer can make thumbnails of .PNGs, but not .RSRs.

That's not to say the Poser can't still read/use .RSRs, it's just they are'nt favored really.

lol your all so friendly, i was just looking because of rsr file because i made new textures for eyes and added them in the texures folder then loaded them with materials room and tried to save them that way in my mat pose library and i did but when i click on them they wont open grrr and all that i could see what was different is that they dont have a rsr file

There is a difference between a Material (MT5 or MC6) and a MAT Pose (PZ2).  Materials are new to Poser 5 and are directly connected to the newer Material Room/Shader Node system added then.  MAT Pose files are the old, but still very much employed, way of setting up materials.  They are two different file formats and non-interchangeable.  An RSR will not help make the MT5 file work in the Pose library.

What you'll need to do is convert the Material into a MAT Pose.  This may be possible by loading the Material onto the target Poser figure/prop and then adding the pose to the Pose library ('+' at bottom of Library).  If the materials are included with the pose, you can edit out other information to make it a MAT Pose.  At worst, you can save the Figure or Prop to the library and edit the file down to a MAT Pose.  It's a cumbersome process, but Poser really doesn't offer the tools to make things like MAT Poses or MOR Poses (morphs only), these being more or less exploits not official formats.

RSR!  ACK!

hides from the .rsr

Mommie, make it go away!!!

lol ughhhh !!!!!! what prog do i need to develope clothes n skins n so ??? i wanna make sum stuff myself lol

You'll need UV Mapper, and Photoshop.  Paint Shop Pro is like Photoshop, butmcheaper.  If free sounds even better look for GIMP, or DogWaffle.
