I have a figure Boston terrier: When I load it and go to Poses I choose a mat file and then Poser 8 on Mac. starts asking me for a long list of ChanVis,and Deltas. Where can I put these files so It Poser 8 can locate all of them without asking me to locate them. Here is where I have them.

Look inside the pz2 file you are invoking and see where it thinks those files are, then put them there.  It may reference yet another pz2, so you may have to check that one also

How do I look into the file and what do I look for. Sorry I've never done this. Thanks

the pz2 files are just plain text, any text editor will open them. If the file is using other files there will be a readscript  line with a file name and path. A mat pose file should NOT be loading deltas or channel visibility because those are morph injections.

It looks like those poses are loading morphs and textures, which is OK .  It may be that your preferences are set to a shallow search path which will limit finding the referenced files.

You can use any text editor to look inside PZ2 file (you can't with PZZ because they are compressed)

For example, below is injecting base morphs to V4

{
 version
 {
  number 4.01
 }
 readScript ":Runtime:libraries:!DAZ:Victoria 4:Deltas:InjDeltas.V4BaseAll.pz2"
}

But that points to another file, so we look in that and see what it wants (part below)

{
version
 {
  number 4.01
 }

** readScript ":Runtime:libraries:!DAZ:Victoria 4:Deltas:Base:InjDeltas.CTRLTongueSide-Side.pz2"
 readScript ":Runtime:libraries:!DAZ:Victoria 4:Deltas:Base:InjDeltas.DSTStrength.pz2"
 readScript ":Runtime:libraries:!DAZ:Victoria 4:Deltas:Base:InjDeltas.FBMMale.pz2"
 readScript ":Runtime:libraries:!DAZ:Victoria 4:Deltas:Base:InjDeltas.FBMMaleNS.pz2"
 readScript ":Runtime:libraries:!DAZ:Victoria 4:Deltas:Base:InjDeltas.FHMGeorge.pz2"
 readScript ":Runtime:libraries:!DAZ:Victoria 4:Deltas:Base:InjDeltas.FHMJohn.pz2"
 ....and more stuff**

so make sure the files are in the folder it is asking for.
 

Sent you a site mail.

Ok I'll give that a go. Thanks
