GAWD, Why does it take so long to bake simple textures from materials?

[Pte Jack]

I've built 11 rather simple materials and I'm baking Diffuse textures from those materials because I need actual texture images. WHY does it take so long to bake that are between 64x64 up to 2048x2048 textures. They've been baking now over an hour and a half and I only have 5 of the 11 done.

Anyone have any suggestions on how to make this run faster? 4 or five of these are just different coloured blender materials from the principled shader and are only 64x64. One would think these would be like a blink to bake.

That doesn't sound right, baking the diffuse of a simple principled shader onto a 1024 texture takes maybe 5 seconds for me.
No idea what the reason might be, though, sorry. I am assuming it has something to do with your bake settings and/or scene/shader complexity but at this point it's just a wild guess.

dont use blender to bake, its ♥♥♥♥. use marmo or substance

Kind of hard to do when a couple are procedural in Blender and you need a sheet. But yeah, that's where i usually do my textures, SP and GIMP.

Correct me if im wrong but when you bake textures you should turn down the sample count in path tracing. It is only necessary to have samples in baking is when you are baking AO.

This is going sound like a stupid question and I use to know where to find Samples, but for the life of me, I don't see the setting in my property panels at all now. Where can I find them? NVM, found them. Ok render was set at 128, I ramped that down to 10.

Also, I found that Blender defaults the Render Device to GPU Compute (doh), I changed that to GPU Compute and it did boost rendering a bit. I don't see an option to use both, and I'm not sure why you have to reset this when I have preferences set up to use both and have my Nvidia Cuda Cores enables.

But thanks Toster, that did help quite a bit in the render speed.

You dont really need any samples at all when baking.
