UV Master work like I think it does?

Ok, so I’m in 3d class using Carrara. I decide to utilize ZBrush to create a high poly detailed mesh. I exported this object and the maps back to carrara. Everything fine so far.

Now, I try to place the high poly maps unto my low poly mesh. Unexpected results. I asked my instructor for assistance but he said it isn’t possible to achieve this. I have been searching for an answer and signs point to “yes I can do this”

To end my heartache…
Is it possible to place a high poly ZBrush map unto a low poly Carrara object?
I may need to mess around to find out how, I just need to know that I am heading in the right direction or waisting my time.

P.S. also am i smarter than my instructor?

why not export out your lowest level in zbrush and use that version, in your other app. That way your UV’s line up. You cannot copy UV’s across mesh with different vert count.
You can bring in your original high rez mesh and give That one UV’s to work with as well.

Please, can you being more accurate in your problems? when you write about the high polymaps, do you mean the displacement maps made in ZBrush?

For your info, you can use ZBrush displacement maps with Carrara, and also normal maps (but you need Deeper for Carrara, a paid plugin: http://www.inagoni.com/e107_plugins/content/content.php?content.2 - perhaps the last release of Carrara support them natively)

But Carrara support the Displacement for sure since Carrara 5…

“P.S. also am i smarter than my instructor?”

I don’t know if you are smarter. But right now you are lacking knowledge. And if the instructor cannot help you with this very basic CG issue then go and get your money back.

Your question is hard to understand as the terms used are not describing a problem in particular. It reads like ‘my hovercraft is full of eel’. Sorry… can’t help. But read up on Displacment, Bump, and normal maps and what they do. And read the manual of ZBrush and Carrara. All is explained in there.

Ok, I’m still noobin’ over here. This weekend I’ll be reading and watchin tutes to prepare me for next week.

Here’s the situation. I am a graphic design student who dabbled in multiple 3d apps prior to starting school. And now that I’m in school they are teaching us basic 3D. So a lot of the nomenclature is missing from my studies. Basically, if it doesn’t pertain to Carrara it doesn’t matter. But I wanted to take it to the next artistic level.

So thanks for your assistance, to all who reply.

Let me try to clarify. I have a model that is built in Carrara. I export this model into Zbrush and subdivide it. I add texture to this model in Zbrush and export both the model and the textured UV maps. When I bring this model into Carrara with textures, everything works. But I want to be able to place this map unto the original Carrara model because the Zbrush model has too many vertices to manipulate for posing this model.

I hope this helps and I hope I’ll find my answer in my readings this weekend.

If you don’t need to animate your model and you just need to do still renders, you can simple decimate your model: it means removing a lot of vertices without affecting the visual aspect of your model. But it creates a lot of triangles.
Then you can use Decimation Master plugin to do this step with the UV option enable and then, export your optimized model with Carrara. Then you won’t have to deal with Displacement maps or Normal maps, just your color texture (diffus map)

That was going to be my next step, to bypass the rigging and just export the model in different poses then add detail in Zbrush. but I have other models that this one will interact with so I figured being able to manipulate it in Carrara would be best.

You have to deal with two different maps. One is the texture map, the other the ‘displacement’ map. The workflow is to take the model from into Zbrush.
Then mess with it, paint it, deform it, subd it. Then you go and go to the lowest subd level again in the geometry tab. From there you export the model again as low poly model. Then generate a displacement map in Zbrush. Search the forum and watch some tuts in case you are having difficulties with the 3d app in question and those maps. You are not the first… it’s been done.
Then export the texture from Zbrush as image file. In Cararra you assign the displacement map and the texture to the low poly mesh. And viola… all looks (hopefully) like the highres mesh in Zbrush.
best of luck

Yeah going through some tutes right now. Where I’m at in the project is not the import of my maps.
They import just fine. What is happening is the maps do not sit on the low poly mesh properly. I inverted the axis like the tutes say but no luck.

I also see that when I export the high poly that I placed in Carrara as a new .obj Zbrush does not accept the textures

back to the lessons…

Yeahhh, you must have something basic stuck the wrong way around. I’m sure you’ll find it. Try with a simple object. Just to get a hold of the workflow. Don;t focus on geometry. Take a simple sphere and subd and texture that.
