In the v2 version of the multi-style mecha testing, new additions include animal mechas such as wasps, ants, squirrels, cats, dogs, wolves, turtles, lobsters, hippos, elephants, rhinos, and sharks. This version performs well at a style strength of approximately 0.8, with steps around 20-25 and prompt coefficients between 7-9. By using specific technical steps and parameter settings, realistic-style mecha images can be created.
