Re: [MORPHMET] Error with read.ply in geomorph
Thanks again, Emma.

Re: [MORPHMET] Error with read.ply in geomorph
Hi Emma, which version of Rvcg did you use? could you send me the file for debugging? I have tested the function with a variety of textured files without issues (at least no R crashes). in case your file is not a png and/or split into multiple images, you should get a message stating: please convert texture images to png format only single texture files supported, only first one stored and if that is the case, when rendering with rgl you will get a warning: Warning message: In rgl.material(...) : RGL: Pixmap load: unable to open file 'Desktop/smilla1_0.png' for reading Best Stefan On 16/12/14 05:02, Emma Sherratt wrote: Dear David and Stefan, The issue was that the PLY file of David has textures, which our read.ply function currently does not support.
