Buying RizomUV

Friday marked the final day of my evaluation period for RizomUV. The application developer graciously doubled my time because most of the first period was spent looking at an older version of the program. I appreciated his generosity.

A full license will cost about $230. But given how much better RizomUV is over UV Layout, it is worth it.

That said, RizomUV is not without its quirks that one must get used to. But if you are aware of these idiosyncrasies and work carefully, you can avoid them. Truly, the biggest knock against the product is the lack of proper documentation.

Some users have started creating YouTube tutorials – I’m not yet sure if I’ll do the same. For now, the best learning resource is a Discord chat channel. You can text with other users and the developer directly.

What makes RizomUV superior to UV Layout? The selection ability. It is far easier to select edges for cutting in RizomUV. It has an edge loop selection. You can select individual polygons and RizomUV will cut them around their perimeter. The application also has several automatic selection features, such as box model and sharp edges.

I mentioned some quirks and the biggest one for me was that RizomUV includes the entire still-folded 3D mesh in the UV space. UV Layout used the metaphor of “rooms” to separate where you perform cutting from where you perform unwrapping. This means that in RizomUV, if you are not careful, you unwrap a part of your model but if there are other visible parts, those will become highly deformed. Basically, RizomUV is trying to unwrap a 3D mesh that does not have any edge cuts yet. The results can be bizarre and jolting.

But all in all, it is a great product. I’m glad to have bought it. Hopefully I will get my bell tower model unwrapped in the near future.
