Mudbox forgot UV example:2
polycounter lvl 9
Hi,
I recently made a model (look at attached picture) , and forgot to uv the model. I know that i can export the lowest level and unwrap that and import that level again, but the problem is that i need to make a new lowpoly version of the model that will work ingame. This is what i want to do.
1. create a lowpoly model in Topogun from the level5 in Mudbox.
2. Unwrap uv:s in other application.
3. import the new lowpoly model into level 1 in Mudbox.
4. Somehow make the level 5 details remain working.
5. bake a normalmap in Mudbox /Xnormal from the high-res. (hopefully aligned with the uv
from level 1.
I hope you understand what i mean. Sorry if this is unclear in anyway. Am i thinking wrong or what is the easiest way to do this ?

there is no need to have the details on the new mesh...
mud is able to bake between arbitrary meshes...
Thanks for the answer oglu, can you please clarify what you mean ? ,
import it into the same scene as your old highres and bake between them...
I am sorry man i still dont get it, If i make a new lowpoly object that is the final version that i want in the game it will be very optimized. Even if i subdivide it like crasy it seems to me that mudbox will never to be able to project all that detail becouse of how the topology is on the new lowpoly object.
It really feels like i am doing something wrong here. This seems like a logical workflow for me:
1. start with a character in Mudbox from the default human model.
2. when the character is done export it ,and remake the topology so
that its optimized and work perfect in the game.
3. import the new mesh and somehow get the detail from the high levels
on the old model.
Am i thinking wrong here ? , and when you say bake you mean displacement maps ?
thanks alot man for you patience.
you can find a lot of tutorials on this topic, either here or google...just search for "lowpoly workflow" or something like that
you can also do that in Mudbox with the Extract Maps feature under Maps, but I would suggest using xNormal as well.
But the model that i have now doesnt have any uv... so how can i bake the normalmap then ?
edit: oglu, same time!
Okay will try if it works ! , thanks.
