Texture high poly?

Mike123

So hi, i have a bunch of questions on how to texture/bake my model. I made a model of a rifle M4A4 from the game CSGO, and i did the uv´s as a pretty high poly model they are all done now and i would like to texture it but i would like to texture it as a high poly because im going for a more photorealistic render for it and well i dont want to do another model (low poly) and uv that. Im going to texture it w/substance painter but i need the maps baked right? So my questions...

Is there a way or is it possible to just texture the high poly, if possible how do i bake the maps for SP (all the requiered maps)?

If not do i need to do a low poly of it by retopology (topogun) and well would i need to uv that again which i wouldnt like to...

I thought about this but i dont know if it could work, could i use the same model (high poly) and make another one even w/ a higher poly and then bake those maps, even if they still have the same details?
I hope anyone understands what i mean by al this!ask for ks! (have images if required)

Depends need to see the model but inherently the idea of "baking" is to transfer high poly model information onto a lower poly mesh. If you aren't doing that then you can try to bake a self occlusion map and that help, you may also be able to bake out a convexity map to help as well and un fortunately I'm not sure if you can bake a normal map without a lower poly model. On a side note ai don't know what your intent is with your model but if you don't make a low poly it won't be game ready and will only have an aesthitic quality. Hope it helped.
