Usage

Insert "SEGA Anima" node to between "Load Diffusion Model" node and "KSampler" node.

What should I do when output image is bad

1. If image does not appear, first thing you have to do is decreasing "training_resolution". Too low "training_resolution" results structual inaccuracy.
2. Adjust CFG. Normally, higher CFG is needed for high resolution output.
3. You may adjust "theta", "base_mscale_coefficient", "mscale_alpha" or "d_mul".
4. Creator of the this node does not know what rest of parameters do. You may do experience with those.
5. If changing none of above work, Increasing steps may work.
