It is the Angela morph that is giving me the problem I can render everything else. It is as soon as I add the morph is when DAZ crashes when I try to render.
I have the Angela morph by Morris, is that the one?
I reset my downloads, and installed it. I loaded V4 with the base morphs and Morphs++ (although not strictly necessary), and applied the morph. All went well, until I tried to apply the MAT for Angela. DS4.5 could not find the torso and Limb maps. I looked in the textures folder and they were not installed.
I reinstalled both installers to a Temp fiolder on my Desktop, checked the folder, and this time the files were there. I merged all of the textures into the correct folder in My Library, and the MAT loaded with no problems, and I was able to render it with no problems.
The installers I have are 11944_4_dpc_AngelaforS4V4_4.exe and 11944_3_dpc_AngelaforS4V4_3.exe, but they did not work properly the first time. Perhaps you should try to redownload them, reinstall, and see if that fixes the problem?
I don’t remember ever having this problem with installers, and whether it was Win7, my PC, or something funny about the installer, I don’t know, but it worked correctly the second time. Give that a try and see if it works for you.
