WW1 - British Mark IV Tank

The Mark IV Tank was a British armoured vehicle used extensively during World War I. Introduced in 1917, it was a major improvement over previous models, showcasing enhancements in armor, reliability, and firepower. Equipped with either machine guns (in the case of "Female" tanks) or 6-pounder cannons (for "Male" tanks), the Mark IV represented a critical step forward in tank design, becoming a symbol of early mechanized warfare.

How to use

This LoRA of a British Mark IV tank (1917) should be easy to use. You can keep the LoRA weight at 1, and you can invoke it with the trigger word mkiv17 (meaning "mark IV 1917"). You can then personalize the tank by adding colour, camouflage, symbols, numbers etc in the prompt.

For other parameters: Checkpoint should not matter, this model works as a realistic and illustrated concept. CFG should be kept around 7 but try not to go above 9. In terms of the Sampler, I use DPM++ 2M Karras 20 steps. In terms of Hires Fix, I use a 200% scale with 4x_NMKD-Siax_200k, full steps (0), and 40% denoising. For Clip Skip I recommend 1 since it was trained with it. But you can experiment.
