The reasons are predictable:
However, the apparent "savings" vanish when you account for the real dangers.
Cracked DLLs often cause random crashes, lower render quality (intentional crippling by some crackers), and conflicts with other plugins.
V-Ray 4.2 has known bugs (e.g., material editor crashes, network rendering issues). Legitimate users get patches and support. Repack users remain stuck with flawed versions.
Many small development teams rely on license sales. Chaos Group started as a small company; piracy hurts innovation, especially for specialized render engines.
