UV mapping odd directions

Krisidious · 3rd October 2010, 03:43 AM

hello I am wondering if someone could explain how to UV map an object that is rotated to face 45 degrees off of the box plane... how can I map it straight on to the face but still have the object rotated.

a valve cover on an engine. pointing up at a 45 degree angle.

thanks for any help...

also is there a way to only select faces that are actually facing you? you know a no back faces selection? this would be very helpful for UV mapping each side of a complex object.

(I've used the "select surfaces with the same material" to circumnavigate this issue. however "select only surfaces facing me" would be great or "select surfaces and not backfaces".)

Answer: at the very bottom left of AC3D UI there are two selection boxes "grid" and "select through" the select through is the equivalent of no back face selection.

still no answer? already bought the software. trying to map an object on a 45 degree angle... any help would be great. .

Select the surface you want to map via the AC3D views and then adjust the vertices in the TCE so that you get the vertices at the right position over the image in the TCE. If you still have problems, post a picture of AC3D with the engine valve cover selected and a pic of the TCE at the time.

A selection tip - hold down control+shift and then you can 'paint' a selection with the left mouse button.

Thanks for your help Andy, I know you're very busy.

I seem to be dense... here is a screenshot of what I'm working on, with the two screens the TCE and the Main view and you can see I have the vertexs selected.

when I rotate it just spins around though. and if I pull individual vertexes it skews the surface.

I'm not building something that already has a picture, I'm texturing what I built in 3d and just painting the surfaces of what is there.

this and the gas cap and the camera are all I have left to map... your program has slammed out all the other maps I've been working on for months in Max... in just a few days. thanks!!!

switch to surface select mode and select just two adjacent triangles of the engine at a time from the main views. Work on them in the tce to make them flat. Then you can position them over an existing image or in a clear area ready for painting later.
