Hi!

I'm using Baker (very handy tool!) and have some trouble with applying the baked texture back to the model. I have a model I created in the vertex modeler and it is simply a hollow tube. I created it by removing the ends of a Constructed 3D cylinder and then Added Thickness.

I texture it in the texture room using the Checkers preset texture. To make it align properly with the model I apply a cylindrical projection mapping. At this point the texture maps perfectly to the model.

Off to the assembly room where I invoke Baker on just the Diffuse channel, get my checker skin and assign it to a file. Back to the texture room, where I assign a new multichannel shader to the model and load the baked texture into the color channel as a texture map.

Now the texture is distorted on the model, the checkers having wavy edges. I get the same result when I apply this texture in my game engine, which is what I'm really doing, but the problem is easily demonstrated just within Carrara.

Is there something I should do differently or is this a limitation of some kind?

Thanks!
Mal

Sorry for this late answer. I didn't see that there were a new post in the forum before today (for some reason, the alert mecanism didn't work).

The process you describe here is the right one, I don't know what is going wrong. Does it diseappear with a higher texture quality ? Otherwise could you send me your file, I'll check it here.

Julien,

No worries on the late reply. I did eventually figure it out, and I should have posted the solution sooner.

It seems that Carrara often generates a default UV map that extends outside the valid UV map coordinates. A procedural texture applied to the object will work fine, but a texture map will be distorted. The solution was to remap UVs for the object using Carrara's UV edit tools. This is unfortunate, because I find the Carrara UV tools to be rather lacking.

In any case the problem lies with Carrara and not Baker. Once Baker had a proper UV map to work with it performed very well.

Cheers,
Mal
