Batch Size: Leave it automatic.

Crop size: Smaller crop Faster to train, is only aware of smaller details
Use or 256 or 512 for better quality.

Log2Lin4：typically used to convert an image from a logarithmic color space to a linear color space. This is a common operation in the compositing process, as the logarithmic color space is better suited for images with a wide dynamic range, while the linear color space is better suited for compositing operations and adjustments.

Check point. You can link other data set with similar content in your training.

Change the RGB channel in the shuffle and connect the mask to the grade, so that the roto of the eye is reflected.

Particle in nuke:

• By changing the axis of the card, you can change the direction of particle emission.

• Different options can change the emission state and shape of the particles

• Adjusting these nodes can change the size of the particles

ParticleTurbulence: change the particle direction and add some blur.

Test of head:

• at first, put in the file of head, and change the texture.

• create another transform which is change the rotate of head, just like particles of head.

• this part, focus on adjust noise and blur and some distort when we export the last step.
