hello=)
im new to z brush an i want to make some items for Dota 2, for that i need to work with X-Normal, so the question is how do i use X-Normal to bake the textures? If i try it the error message: The lowpoly models geometry is void(no triangles). Please sure you selected almost one lowpoly mesh and is marked as visible.
ok hope someone can help me
cheers Laslo
you need a highpoly and lowpoly object inside of xNormal. I would appear that you don’t have a lowpoly as the error message is saying.
hmm the item im working on only have less than 500 polypoints
could u please explain me what u mean with low and high polyobject?
and how i get them to xnormal
thank you=)
Laslo
ps: do someone know a good tutorial wich shows ZBrush 4R6 and xnormal?
if it has only 500 polys,
why and what is there to bake?
grtz p
Call that mesh low poly and clone it, subdivide it to make a higher poly one. I don’t know what xNormal can import. And since reading more of the post again and seeing the word tri’s, you may have to divide a couple times and then run DecimationMaster.
xNormal is a baking software. It is made to transfer highpoly information to lowpoly models. You can find a ton of tutorials on http://xnormal.net/Tutorials.aspx
oh nice thanks =)
xnormal bakes textures using the detail on a high resolution mesh and organizes the surface information using the uvs of a low poly version of that model. The models are usually saved on a hard disk and do not have to be open in any applications for the baking process as xnormal only references them. This makes it possible to get incredible detail onto a much lower resolution mesh which allows for easier rigging, animation, final rendering or integration into game engines.
xnormal handles .obj files that you can export out of zbrush. You can export a high poly model (many millions of polys but it depends on your computer) with a texture or with polypaint. If you export a highpoly with a texture the highpoly needs uvs and the texture must be applied to the model. If you export the highpoly with polypaint then your model needs no uvs but you have to check that the colorize button is activated under the polypaint menu.
The low poly mesh is usually made in an external application but with zRemesher and even the topology tools in zbrush you can produce an excellent low poly mesh. There are a lot of retopology tools out there and the low poly is usually drawn over a decimated version of the zbrush highpoly. If the low poly is made this way then it is possible to use the decimated version of the highpoly as a reference for a projection cage. The projection cage is needed in all but the most simple of shapes. When you install xnormal then usually an export plug (xnormal .SBM) will be available for the purpose of exporting the lowpoly out of the external app. The SBM exporter allows a cage to be included with the export. The model with the cage must be a mesh not an editable poly.
The tutorials will show you how to use xnormal but there are a few things that may help. If you are exporting the highpoly with a texture attached you will need to enter that base texture in the same line as the hipoly model in the xnormal ‘High definition meshes’ dialog. You can find the correct texture in the same folder you exported your highpoly to. The texture will have the same name and is in a BMP format. You can leave ‘ignore-per-vertex-color’ checked to bake AO maps. If you want diffuse maps then you have to use ‘Bake base texture’ under the ‘Baking options’ button. If you are using a polypaint zbrush highpoly then you have to uncheck ‘ignore-per-vertex-color’ and use the ‘Bake highpoly’s vertex colors’ option. Uncheck ‘ignore-per-vertex-color’ if you want to bake AO maps.
Hope this helps
Cheerio
thank you kanga this helps me alot =)
Glad I could help!
Reading the post back it looks really complicated but just in case you dont get the textures you expect then it might be some of the things I mentioned above.
ZBrush and xnormal are a perfect combination. You are going to have a lot of fun.
