Hi Paul,
Weird problem in Poser2014 Pro:
Have Octane rendering in the viewport.
Change the material node type from a material with texture images in it from ex. glossy to diffuse
This crashes Poser with an error on wxmsw291u_core_vc_custom.dll (2 times in a row, then Poser closes)
This happens with both versions 1.14a and 1.16a
It does not happen when the material nodes are changed without the render window open.
It does not happen with materials with just RGB values.
It is independent from the scene, any object, even the simplest primitive, with a texture provokes the crash.
This does not happen wit Poser2012 Pro (on the same machine).
Extra info: i use a seperate videocard (onboard Intel HD4000) for Windows. The Nvidia card is dedicated to rendering alone.
