If you use a viewportshader like mine, it ignores the Driver settings. Though 4096 is really, really big and you will probably get into trouble if your spec and diffuse are also that size.
I gotta stick with Rock Bottom here: rendering a map out at larger resolution and scaling it down does give you better quality. Scaling a 4096 to 1024 essentially gives you a 1024 with 4x multisampling. You have to make sure to control the resampling though, and you have to keep in mind you will be scaling your padding as…
ok so in conclusion baking a 4096 map and lowering it to 1024 with Bicubic Sharper in photoshop works? good? is it also ok to reduce and then make the difuse map?
