Mesh texture in different Visual Styles

[Anonymous]

Hi all, 

I see the differences in applying material to a SubDMeshes (with texture coordinates) created in different visual styles.

I've noticed that texture image is always applied rotated by 90*, and therefore always multiply V coordinate by -1.

But when mesh is created in visual style "2d Wireframe" and then switch to "Realistic" texture remains wrong rotated.

There is several ways to switch visual style (using properties window, using "Visualize" tab, using Visual style controls in a View port and using Visual Style manager). Only the last one (Visual Style manager) seems to work properly, because texture is applied well when switch from Wireframe style to Realistic.

Please, see the attached .gif 

Maybe I am doing something wrong? How can I affect the texture displaying?
Or it is a AutoCAD's bug and material with textures should be assigned only in realistic mode?

I am using AutoCAD 2016, SubDMesh and texture material was created programmatically using .Net ObjectARX.

Hello,

We have also recently experienced this issue, and are very interested in a resolution or work around.

We have noticed that since subdivision mesh handling supported texture coordinates in AutoCAD Map 3D 2012, that the default display worked until AutoCAD 2016, after which the default appears to that the texture is vertically inverted then mapped with the texture coordinates.

However, as noted in the original post, it is possible to start with an incorrectly inverted texture application and by changing the visual style in some specific way, it can appear correct, and vice versa.

We are writing textured subdivision meshes for years with different REALDWG versions, and the behavior appears to be the same for older and newer versions of the data.

Looking forward to your reply,

Regan

An sample data case, with screenshots depicting the results of setting the visual style in two different ways.

Note that these were taken with Civil 3D 2015 as AutoCAD. Newer versions of AutoCAD as mentioned produce the incorrect texture behavior by simply switching from 2D view to 3D view mode.

Still waiting for a reply / confirmation / work around for this.

Thanks,
