Some OHous objects will crash binarize, I dont know the p3d names at the moment but will try to look them up.The lousy Binarize usage, for some reason will not function properly on my computer, try to include a tool that will take image back to wrp with the push of a button.
I imagine it's a software issue cause the computer reports that Binarize exe failed to initiate properly. Do you wish to send a report.
Are there any other programs that could possibly convert back to wrp , I love this tool especially the road tool, but with Binarize not working for me no sense for me to use it at all.
When I'm binarizing my own wrp, in the end binarize crashes, so you're not alone here

What comes to us making utility to replace binarize, I dont know as we dont have such knowledge at the moment. If anyone knows some technical details, feel free to share and we'll see what we can do.
Also make note that you do not NEED to binarize your wrp file for OFP usage, its our understanding that OFP has "internal binarize" so to speak. Of course if you need to get 4WVR file into Visitor or WRPEdit, then you indeed need to use binarize.
