Poor texture resolution after baking with Arnold

[Anonymous]

Hi,

I currently trying to bake some custom PBR materials I've created onto objects in a scene. I've UVW unwrapped the objects as well as tiling the textures to achieve the desired look. Everything looks good in viewport and when rendering with Arnold. However, when I bake the textures and save the maps, the resulting maps look blurry, like the resolution hasn't bake correctly. I've tried with different forms of lighting to no avail.

I'm trying to apply the textures to materials in Unity.

Could anyone give any suggestions to how I may fix this, please?

What are your settings for Baking? Can you upload one piece of geometry for testing?

Hi  CiroCardoso3v,

Thanks for the reply and sorry for the delayed Response.

So I've attached what I hope is what you're looking for.

The Model is only very Basic, it's just a piece of floor which will be embedded into terrain and covered by quite a few objects.

If you could offer any assistance that would be great!

Cheers

James

Hi CiroCardoso3v

Thanks for the link. Possibly, you've helped me work out where I'm going wrong. I think the answer lays in UDIM multi UV tile mapping. When I bake, I think I'm trying to bake a 2K texture on an area about 1500M2!!

If you agree, could you point me in the direction of a UDIM tutorial, or offer any advice on how I go about baking with a massively tiled 2k texture?

I have tried multiplying the tiling amount in the UVW Unwrap editor window, but that doesn't seem to translate to the baking render. I see there is an option for UDIM in the UV channel column, however, I've tried adding different map channels to parts of the mesh, but without achieving any good results. My only other thought was - I could try making an enormous texture in photoshop, tiling the 2k texture hundreds of times, but I feel it would reduce performance in Unity somewhat.

Cheers

Glad it helped. I think for the UDIM is better if you check the Arnold Answers. Lee or Stephen will be able to reply to that.

No problem. I don't use that feature that often, but on Arnold Answers you
will have the Devs there that will know the solution.
