I've created a checkpoint using Dreambooth that is a merge of two LORA's I have made previously. This checkpoint can be used to create epic, sweeping landscape shots in both a realistic and a fantasy style. This checkpoint was trained on, and is a merge of the excellent Landscape Photoreal checkpoint, which you can find below in resources. Please also use the ClearVae VAE for best results, as it works extremely well in my testing. I have also had great results of generating at 512 x 512, with Multi-Diffusion at 1224 x 1224, however this will increase the generating time significantly (most of the sample images you see above were generated using these settings.)
If you are interested in similar results to these, but want a smaller download, you can check out my previous LORA's here:

I've also included the training data, if anyone is interested.
