[Q] Big Mesh Textures

LaurentiuN · Mar 2016

Hi there,
I was wondering how a unique mesh like in the example ( the door ) gets such a nice crisp details, do they use a large texture like 4096? i dont think a 2048 will give you nice details especially when its a big object that occupy the whole screen. Any thoughts?
Thanks.

Something like that could probably be done with tileables and good use of blendable materials. Another option would be to simply use two 2048 maps or a 4096x2048 rather than go all the way to a full 4096x4096.

Yeah but with blend stuff you need all kind of masks for edge scratches and dirt etc...the shader will get big and maybe not that good for performance.

Is that Doom? if yes, don't they use mega textures? That means dynamic mip mapping, everything around gets quickly mipped, leaving you enough material resolution for that door... I could be wrong, but that's what sounds like to me.

Yes, its doom and i dont know anything about mega textures, what means dynamic mip mapping? I know what mip mapping is but dynamic ?

Not sure what it means but unless you're planning to use idTech, I don't think that method is going to help you anyway since as far as I know no other engine uses megatexturing.
