A lot of folks have most likely come across this issue.
I use Autodesk Alias to build geometry and use Maxwell Studio to render.
When I import a simple cylinder in Maxwell Studio and choose the 'cylindrical' type mapping option, the result is perfect after minor adjustments. But when the cable geometry is laid out in a natural, relaxed non 'directional' way, then a close up shot is not possible because it reveals the flaws of the texture UV directions. The best way I was able to fake it was by using the 'cubic' type.
Does anybody have a suggestion, a way to get around this? A plug-in is not available for Alias. :(

Thanks for any help I can get.

Hi I'll see if I can help. It implies using 3ds max, if you have access to that. If anyone else knows better I'd like to know as well.

When I export to obj from proe (or wildfire/creo elements) mapping is set to planar or xyz coordinate system. This means the nice uv-coordinates along the surface of for example a wriggling cable is lost. I assume the alias export is doing the same to the uv on your model.

My way around it is to either export the specific surfaces that need that along-the-surface mapping as iges into 3ds max. There when I convert them to meshes, the uvs are there as they should after conversion. From there you can go to studio.

The other way I have is to make a spline 3d line in 3dsmax and check renderable and choose diameter as neccessary. Then that object in turn can be coverted to a mesh and exported, with good uvs.

It seems strange however that Alias can't export good uvs as obj is the good old Alias own format for triangles/meshes...

Also I guess any polygon modelling software could produce that cable with uvs...

Hope this helped

Thanks Johan,
I will try to export from Rhino since there is no setting to choose from alias when exporting as obj.

Thanks for you help.

Old thread, but the issue persists. I contacted my Alias support. Since version 9, Alias OBJ format is exported without surface texture coordinates. So, if you need to map a surface directly (not projecting planar, cubic, spherical, cylindric, etc.) your best option is to save the Alias surface(s) in .IGS format, open them in Rhino, assingn a surface texture, and export the OBJ from there. Odd, but true.
