Clint, I am not sure if it is worth it if you already have version 3. For me it was worth the purchase for the 3d material creation I use in 3d modeling. I do not use it for the CW designer pattern building at all. I only mentioned it because I know there are some folks on here that use it and are way more familiar with it than I am.

Maybe someone smarter than me on the software can give us their 2 cents.

I am discovering material/texture for 3d models is harder in some ways than just building geometry for the models.
