Help please. I bake normalmap in another program. UVunvrap changes every time you start Houdini. Maybe because of the compression of solo lovpoly model. How to make that UVunvrap not changed.

Sorry, no time to check your .hip file but what if you lock the divide1 node?

Edward did not help. Then look at my file please.
xNormal prog does not accept a model in which the polygons have more than 4 edge so I put divide1.

It looks like a bug in the PolyReduce node to me. If I right-click on it and choose “Lock”, then saving and reloading afterwards gives me consistent results. I'd submit a bug with your .hip file. Use the Support menu on this website above.
