I've been using Genetica for what seems like a dog's age, and over the years I've become quite dependent on it for generating textures for Second Life. However... it has failed me and I don't know what to do.
The Issue: I am building a texture in the Canvas. I have two layers, with a single rectangle in each. I go to the top layer to Style; the first part of the node is a Gradient fill at a normal blend. So far, so good: the style preview renders in a timely manner. The second part of the style is a second Gradient fill at a multiply blend. I set up the gradient (type, direction, etc.) then go to edit the colors. I get as far as adding a node to the gradient and try to change the color... and the preview rendering starts and everything freezes. Production halts, and the program can only be closed through the Task Manager.
I'm still using my antique PC running Vista Home Basic (!!) and Genetica 3.6 Basic. Up until yesterday, everything has been running well and life was beautiful.
So, the question becomes: Where does the Preview Rendering happen? CPU? GPU? Some dark corner of the Outer Planes? Knowing where may be a clue to what is broken on ol' Bessie.
