Baking models with multiple ultra-high detail diffuse textures (e.g. 10 x 8k textures) would typically require a 32k texture bake. Whilst InstaLOD is capable of baking these massive textures, many modern-day render engines only support textures of up to 8k. Therefore it would be desired to create multiple 8k textures for the output model. Whilst InstaLOD currently does not support this behavior, this feature is already on the roadmap and will hopefully be released in a future update.
Although InstaLOD does not currently have the capabilities of baking multiple diffuse textures within a single remesh operation, there is a workaround to achieve the same result with just a few steps.
Make sure to turn off any texture baking features as this will only slow down the process. Textures will be baked in the end.
Split the remeshed low-poly model into individual parts
UV unwrap the parts individually.
Bake the high poly details to the low poly meshes. Specify the texture size and output channels in the "Texture Output" settings.
To bake multiple parts in one step, duplicate the high poly mesh and rename it to match the low poly. Make sure to add the suffix
_low to the individual for correct baking behavior. More information on baking can be found here.
If required, combine the parts into a single node by using the
