Yes, I can tell you the work around, since I'm having this problem since Poser Pro and they've never been able to resolve it. I've reported the issue again with P8 and SM is still working on a solution, but this problem has been there since P7, so I'm not sure if it will ever be solved.

The solution to the problem is very easy. Simply copy the textures complete with folders, into your P8 runtime. That will solve the problem. Poser 8 seems to fail to locate certain textures in external runtimes, but if you place them in the P8 runtime, the problem is solved.

For example textureX.jpg gives you a problem. It's located in C:Program Filesmy runtimesRuntimeTexturesRDNA textureX.jpg

Just copy the complete RDNA folder to where you have installed Poser 8. The you would get something like C:Program FilesPoser 8RuntimeTexturesRDNA textureX.jpg

Make sure you copy the files and don't move them, they still need to be in the original runtime for whenever you apply the item it belongs to, in a scene. First time it will apply fine, after saving and re-opening the problem comes most often.

I've done this with various texture folders and it works great, problem solved for me. The bug is still there, this way you get around it.
